these are the pairs that i have.

Attached Image

rx is a 4 lobe rhcp skew planar and tx is a 3 lobe rhcp cloverleaf. just found some extra info:

QUOTE
The Skew-Planar Wheel is best suited for the receiver, but will work pretty well as a transmitter antenna as well. It has an excellent radiation pattern and very low gain. The reverse polarization rejection pattern is much better and more uniform than the Cloverleaf, making it excellent for the receiving end. The lowest SWR possible is 1.2.

Gain: ~1dBi
Lowest SWR possible: 1.2
Directionality: Omnidirectional
Difficulty to make: High
Best suited for: Video receiver


so it can be used as either but there are best suited conditions. i have a 4 lobe skew-planar antennas on my other quads(as TX).
so in conclusion, the TX/RX pair type of antenna is not a scam after all. it's just best to use them in that particular pair configuration. myth busted! sweat.gif

this why learning to fly with GPS is dangerous. "commercial" operators are ruining the hobby mad.gif . as always, i blame DJI and their drone enthusiast community as well. hmm.gif

hello, i just gotten into quads. got myself a radiomaster tx16s and currently practicing in simulator...its so hard...even turning left n right is hard...
do you know any active FB or whatsapp group to join?
*
a beginner with a tx16s? wow that must be pretty confusing at 1st. opentx is not actually beginner friendly. 😅

i,ve recently upgraded to the same radio as well. after 4 years of fs-i6. i did find it confusing at 1st. at least there's lot of video guide for it.👍

yup, controlling 4ch at the same time is not that easy. just need to keep practicing until it becomes muscle memory. usually your brain will click after some hours in the simulator.

I dont join local groups, when you are part of a group, you get poisoned easily.😅 this hobby is already expensive as it is. i usually fly alone, which can be scary when you're doing fpv.

the usual question is, where are you from?

lol still ok, not tht hard to understand. have been following a youtube channel with great opentx guide.

im based in penang.

mind share how u learn when u started? do you straight practice using real drone or sim?

im now practicing hovering in place in simulator, its hard to stay in place.
*
i started with helicopters. from coax to a honeybeev2. started doing sims after the honeybee, so it's not too difficult by then. still can't fly upside down reliably though sweat.gif . didn't have the funds to go to 6ch heli, so i moved to quadcopters. also, heli flying was dying and spare parts are becoming scarce.

naturally, a quad is easier to fly and maintain by design. so i'm stuck here for now. maybe someday, i can actual get a 6ch heli. good offering these days. back then, it was very expensive and choice were limited.

do you have a quad already? get at least one micro whoops. these things are good for indoor practice and with prop guards, they are resilient to crashes. good for beginners. these things are my go to these days, especially during this PKPB period. just have to keep flying laugh.gif .

keep practicing the hover. hovering is your "stop", so you must be able to hover steadily(and manually) at will, especially in a panic. this will save you from a lot of crashes. nod.gif

Similarly, I started on simulators DRL and Velocidrone and find it very hard to control at first.

I used to think practice hovering first is the way to go. But what I found out that gave me the instinct to control is to just move forward. Look forward at where you want to go. Eventually you'll get the hang of of it. Set challenges for yourself as you progress.

This hobby is very challenging, yet very satisfying and rewarding. To me, I can relate it to playing guitar.
*
i do both guitars and rc flying, and i would say hovering is your basic strumming. if you start with a quad, even more so if with dji stuff, yup this could work. hovering is not that important to practice too much. since stabilizations helps greatly. but not knowing to hover with a heli means bye-bye within the 1st few seconds nod.gif akin to you just want to play heavy rock on your guitar. strumming can be skipped since you'll be mostly "chugging it". cool2.gif laugh.gif . so, from my own experience, hover 1st is basic.

also, u can't really do smooth landings if you can't hover precisely. you see this a lot in YT videos. they just disarm when close to the ground. dropping instead of landing.

QUOTE(chinti @ Oct 15 2020, 02:10 PM)
havent gotten a quad yet but already got a list of parts i wan to build my first toothpick (i like smaller size rather than standard 5inch)

planning to get the mobula6 micro whoops to practice for now. not sure should i straight get a goggle too as well or just practice with line of sight
moving forward is a lot easier than hovering tho.

i can move forward and turn at higher speed in velocidrone, but i cant hover at a same location for long.

one tiny movement on the gimbals n my drone is pretty much everywhere  rclxub.gif its so tough to have tht precise micro movement
*
a note on building yourself, i wouldn't advise to beginners. even with my friends, i'll always point to a ready build ones. PnF, BnF or RtF.

reason being, circuitry doesn't always work the same outside of theory. you might get grounding issues that interfere with your vtx or camera signal, simply because carbon fiber is conductive. you might mess up some soldering that kills your board. all those "good" stuff. if you really want to take the challenge, get a basic multimeter. it's an indispensable troubleshooting tool.

QUOTE(seefutt @ Oct 15 2020, 03:35 PM)
Or can just get something like BetaFPV VR01 about rm250 just to match up with any tiny whoops and enable you to fly.
Flying inside house is a very good learning experience,you can fly anytime regardless of opportunity or weather. And it trains you looking thru goggles and having a sense of the space around you. Once you fly outdoors, it felt so much easier.

The thing is, I was in this dillema too when starting out.
I decided I wont invest in analog FPV and just go straight to digital, as good analog stuffs can cost as much as digital. If i can spend 1k+ for a midrange analog goggles. I might as well go all the way and get a huge jump in image quality, plus I dun have a collection of analog quads sweat.gif
After seeing digital, I just can't justify analog anymore.

It is expensive, but have to ask yourself if you really want this hobby.To make that decision, get a cheap but reasonable analog box goggle and a bangable quad to play around first laugh.gif
*
not really, at least not yet. digital google are still a lot more expensive than a decent analog. then there's the VTX and camera. you can get by with cheap camera and vtx with analog, but with digital, those parts alone can be more expensive than your entire machine. imagine if you crash somewhere where you can't retrieve it? shocking.gif

analog is better IMO in terms of choices and price range. digital is mainly DJI. and DJI is notorious for their closed eco system and milking money scheme. yes, i hate DJI, if it's not apparent enough laugh.gif

also there's compatibility issue. analogs are pretty much compatible amongst different manufacturer. digital is still in its infancy. maybe when there are more competitions, it will be more awesome.

Hi all sifu, i need some guidance on Drone, I have purchased a DJI, but due to my area is near to the airport, always need to request to unlock zone, which is quite annoying and not always get approved, I need to use it for land construction, is there any good drone that allows to flight without disturbing on the GPS restricted zone? feel free to pm me.
*
i think only the big companies have this restriction. the cheaper clone variant usually don't. so, you can try looking into other brands.

building you own GPS enabled drone from a diy kit is also an option. of course, you need to pick the right flight controller to match the DJI feature, like autonomous flight and RTL.

if all else fails, manual flight with stabilization is always available.

Thanks for the reply, anyway is there any other brand equivalent to Mavic Air 2 with No flight limit? Any other guide to build own GPS enabled drone? You meant I can DIY the Drone controller to match the DJI feature? is it possible?  hmm.gif
*
too many clones of the mavic around. i've lost track. some are good, some are just toys. best to look up some reviews. of course, you want to look at the features properly.

for dyi, you build the quad. the flight controller you buy premade. building a flight controller is not for mere mortals laugh.gif . again, it depends on the features you want. for something like a mavic, it's a bit tricky. with the hand gestures and tiny gimbal. those a pretty much proprietary tech. the things you can easily do are the GPS hold, RTL and autonomous flight. depends on the flight controller's capabilities. and you have to program everything yourself. nod.gif

it's people like this that ruins the hobby! flying along power lines is just irresponsible. complete jack a$$ with too much money, this one.

looking at the flight and description, he's seems new to the hobby. it's like an idiot with a gun. for sure if he hits those power lines, it'll make flying more regulated for us all. if you know this guys, please smack the idiocy out of him!

need some help here.

i'm trying to convert my old 35Mhz honey bee2 to 2.4Ghz. been using some spare flysky receivers and it doesn't seem to work. conditions:
- cyclic servos worked fine and smooth
- ch3, throttle works, but it's stuttering. as in, the motor are not spinning smoothly
- ch4, rudder has no input at all
- tried using fs-ia6 and fs-ia6b receivers, same case.
- tried using fs-i6 and tx16s transmitter, same case.

it's a fairly simply affair, i think. just 4ch pwm map, with the same AETR configuration. or does the analog radio receiver sends different values to the 3in1 controller? anyone has an idea? use different receivers? use the older AFHDS protocol? anyone tried converting an old esky lama from XXMhz to 2.4GHz before?

Helicopter rudders is using a tail gyro to control the rate and head locking mode.  You'll need to activate the switches and knob for tail for CH 4 channel and fine tune to get it to work.
*
Thanks. But shouldn't CH 4 would have some kind of output when i move the stick? in my case, moving the rudder does nothing to the tail rotor. but when i rotate the heli while there is some throttle, the tail motor would move.

i've seen some tutorial on converting Esky's 35mhz 4ch heli to 2.4Ghz. seems pretty simple and straight forward, albeit none was very clear. i have configured my eachine e160 to my tx16s. i don't think a 4ch heli would be more complicated than that. do share if you have some details how to actually get it configured....please. it's not easy to get a 35Mhz crystal anymore. last i bought it was when rcsmart was still in Amcorp mall cry.gif .

p/s:
one of the tutorial i've seen: http://kenbuys.com/hobbyking-tr6a-receiver...nkenstein-4in1/

Its very hard to explain but definitely you'll need activate some kind of tail rotor gyro rate (rate mode vs head lock) before the rudder can be activated.
Like in 6CH CP helicopter in my collection there 2 channel assigned to the tail rotor.  One to control the tail rotor rate mode via AUX switch (CH5 or CH6) on tail rotor Gyro module and one to control the tail rotor movement after AUX switch flip the modes on the gyro.  On 4CH version (fixed pitch) maybe you'll need to adjust the PWM signal to activate it.

I have bunch of 6ch 450 CP heli and 4ch fixed pitch too.  Used to have an old ESKY Belt CP.
» Click to show Spoiler - click again to hide... «


the 3in1 only takes ch3 & ch4 from the esky receiver. the aux channel for gyro is mainly for CP helis, i think. or the newer FP stuff with 6g mode. that part i understand.

by adjusting the pwm signal, you mean adjusting the range? i've tried messing around with the endpoints. doesn't help in my case. it's like when i use the flysky receiver, the mixer and gyro dont work anymore.

what i haven't tried is channel reverse in ch4. could it be that the mixer killed ch4 as it was in full throttle on start up?( i just thought of this)😅

the 3in1 is not broken for the record. when i switch everything back to 35mhz, it flies like used to. not a single problem.

Did you use heli mix mode in your 2.4ghz digital controller?  Probably like you mentioned before the Honey Bee maybe already have it own mixing onboard electronic.

yup, the honeybee does have it's own onboard mixing in the 3in1 board. in the form of a "proportional" pot. i used it for tuning, so i'm sure i don't need mixing in the TX.

Pot tuning is quite sensitive,  lots of trial and error to get a stable tail rotor reaction. So how's the progress?
*
it's old skool laugh.gif

i put it back to the 35Mhz controller and it worked great again(i hate the 8x AA requirement). just itching to fly it biggrin.gif . plus, too much micro quad flying is getting boring, especially in this rain season.

i'll try the reverse rudder next time. i'm sure the 4ch ET4 tx is not that fancy to do any complex configs on its own.

Well if it doesn't break don't fix it, 35Mhz controller is actually very good and much preferred for long range FPV....make sure its FM modulation frequency not AM.  thumbsup.gif

yep, it's good except for the fact that:
- it needs 8X AA battery cry.gif
- the crystals are hard to find these days. rclxub.gif
- you don't FPV with a honeybeeFP laugh.gif
- the 35Mhz esky et4 don't really work with anything else. blush.gif

i would much prefer to get it working with my fs-i6 or TX16s.

Ya cos that time seller say 4s no stock, so buy 6s only. Dunno much about 4s vs 6s until someone explained to me lol.
After fly then know how 6S is. the power distribution punch is awesome.

You can buy from rchopez on shopee, thats where i bought mine. Guy is super friendly will even send whatsapp video explaining the functions etc.
*
6S is too much power for 1st timer, for sure. also 6S batt are heavy and more expensive.

when in acro, you need air mode on. so you can flip and roll with zero throttle. but air mode is meant to be use....when in the air. so put it on a switch and don't try to land or take off with it. don't be Joshua Bardwell and enable air mode all the time. it just creates headache laugh.gif laugh.gif .

i'd say stick with what radio you have, unless you actually have a need to upgrade. like needing the MPM and external module flexibility.

openTX is awesome and powerful, but the learning curve is harder. in the beginning, you'll spent more time configuring the radio than actually flying laugh.gif .

there's always some idiots out there trying to make it hard for us all. i'm sure some opportunist politicians will try to pass a new law about registering your drones in the future. shakehead.gif

as usual, i blame DJI for making drone flying easily accessible, as long as you can fork the money. no common sense required. "you don't need training, mavic is safe to fly on top of large crowd" doh.gif
