For FPV you will need FPV goggles or monitor, a drone that comes with camera and VTX and lastly a hobby grade TX.

For RM500 is a bit too tight. I would recommend you to start with micro such as this Eachine E010S which is the current hype Tiny Whoop clone.

For TX you may want to consider either Frsky Taranis (around $200) or Devo 10 (around $100) route if you're serious going towards hobby grade. I personally using modded Devo 12E and Devo 7E.

actually an fs-i6 is not a bad choice either for entry/intermediate level. USD50. plus, it has a 10ch modded firmware. nothing beat it at that price point. drool.gif

I have that too but under Eachine branding. I do agree for entry is good but the protocol choice is just limited to flysky and the gimbal feel toyish too.

Whereas a modded Devo 7E will have limitless possibility and the price is just $20-30 more modded with 2 extra module.

What situation that 2 blade props will break in air.
I think this is second time the 1 of the blade break around the hub connect section.

And quad crash another break on landing skid....w*f I mean...

I think there no way other to change CF props?
*
that is a mystery indeed. i don't see any reason for it. unless it's hitting something at high speed, like a big@ss bug.

I have huge library of props for many models i collected for decades, Gemfan intentionally build fragile at root so that it won't damage the motor during impact aka "crumple zone" effect, they consume power during RPM but trade-in for their speed.  If you want tough prop at root get "APC" style prop popularly used by early days heavy duty multirotor or used by fast funjet plane  like GRAUPNER prop or Master Airscrew despite was build for planes.  Carbon prop is just a marketing fad, build to lighten the load during spin and it splintered if it broken upon impact which makes it worse than plastic ones. Carbon nylon (sometimes aka composite) is build solid/rigid for slow high load flying but does not resist break point during yield.  The best overall prop for multirotor interms of durability and lifespan is GWS type both DD (Direct drive) = speed and SF (Slow Fly) = heavy load.

As for FPV, the cheapest one is eachine vr007 but it doesn't have dvr. If would like to record my flying footage, what are the goggle/fpv monitor alternatives that is not too expensive like the fatshark rclxub.gif ?

also I see there is more people using goggle than monitor attached to the transmitter. Thanks for the recommendation and nice review.

Eachine VR D2. if you can get it cheap. banggood don't ship them here anymore, so would be hard to get it below RM400 these days. locally: http://www.rchopez.com/webshaper/store/vie...roductItem=3517 . still cheaper than fatsharks.

Dang! I just found out after reading your post that Banggood don't ship anything that comes with lipo to Malaysia anymore. No wonder recently, they don't ship me anything with lipo.  ranting.gif
*
yup, i talked to their support personally. they say it's a "logistic issue". a real bummer. eachine is affiliated to banggood, so there goes our source for cheap stuff cry.gif .

i managed to get my VR D2 just in time, just before they stopped shipping.

you still buy parts and anything that's not lipo battery related though.

Just recently just bought an R/C car with 7.4v 1500mah Li-po pack inside the package from Banggood.com, now flying towards my door step as i check via tracking number.    So far so good.  Wonder why you can't get your lipo in the box?
*
i lost a qx90c in the mail since January. in Feb i start noticing the "warehouse can't send" notice.

maybe cars are from a different warehouse...that would be my guess. looks like they allow cars with lipo.

Lost in mail?, which mail service you use?   I remember later February i did received an Eachine quad with 2x 1s 500mah li-po in it so far no problem, its via DHL.  I pay more for extra security and for speed.
*
i use standard shipping, which usually take a just little over a week to arrive(including weekends). no problems before. in fact, it was split to 2 orders. the 2nd order did arrive as expected(some parts, no lipo). however, banggood did not use the normal shipping company with the 1st order. tracking number was different than normal.

ended up with a full refund.

Just now Tmart email me saying they can't ship my extra h36 batteries. The boldclash motors shipped just fine.

So i think most of online websites now don't ship batteries to some countries anymore until maybe they change logistics partner.
*
gearbest can still ship with lipo. just ordered my 2nd qx80. but i still hate their support and product description. gearbest version of the qx80 is assembled and cheaper than other places(ATM at least). nod.gif

currently im deciding to go straight from h36 to kingkong 90gt or q100.

q100 seems more durable and it have canopy over the electronics and battery can mount on top, also seems more durable.

90gt is tempting cause of i want to feel the power of brushless since i already flying brushed toy quad, also it include props guard.

the price difference about rm 250, q100 around rm500 and 90gt rm750 both rtf with fsi6. is it worth it to go for brushless for a newbie ?
*
depends. brushless would obviously have more power but indoors it can be fairly dangerous, even with prop guard.

brushed is safer indoors but it can be sluggish if too heavy.

so depends on what you want to do. me, i keep the brushless outside and brushed inside. nod.gif

Yeah its true not much with support/after sales service from GearBest but the pros is that they can delivery some lipo packs shipped to malaysia easily.

also, gearbest's points are more valuable. you can have product discount + GB point + GB wallet to bring down product price to dirt cheap. drool.gif

banggood wins with very detailed product description and good after sales service(just a bit better).

received the quad today, doing some maiden flight at my condo park. Feels different from my other toy quads, more powerful and fast when maneuvering.

The props seem easy to break, if its not the props guard surely already broke some of it. Any recommended spare props and also spare motors since the motors quite hot after flying back and forth for few minutes.

I noticed when I full pitch going forward and release the stick the quad seems too fast in stabilizing itself (as a noob, angle mode ofc innocent.gif ) and the quad swinging, end up it lose altitude and touching the floor since i only fly about 2-3 meters. any guide to better tune those self stabilizing speeds.

[attachmentid=8651192]
*
probably need to tweak the PID on the angle mode. try dialing up/down the Level->Strength(Angle) to alter the stabilizing strength. if that doesn't help, then you probably need to tune the PID entirely. you can probably find a few samples from google/youtube.

Hi, just purchase a JJRC H36,
maybe i just too noob at flying, i just cant make it stop at mid air
it either too powerful hit the ceiling or drop to floor......
is it because of the flight controller?
*
to get it to stay in mid air WITHOUT a barometer, you will need to balance the lift-to-weight ratio. if it's balance enough, at some point of the throttle (usually not middle) your quad/heli will just stay at the same altitude(without cyclic or external interference(wind), of course). not an easy thing to do. i got mine balanced by accident when i decided to go with 5040 props instead of 5030. it's not the same as alt hold though.

else, just learn throttle management. don't be lazy like AP drone flyers. laugh.gif

Hey guys! Any home builders here? Just started a personal project, and am trying to build my own RC airplane (was inspired by youtube, and countless articles found on the internet), out of foam boards, balsa wood, glue, and tape. Have no experience flying RC airplanes at all  laugh.gif

Also, do you guys happen to meet up ever so often to fly together?
*
if you have no experience, better buy a ready built flyer. the logic being, you need to know how it all works before you can build one. same thing as building your own kite. you must first know how a proper kite flies.

Finally got the opportunity to do an fpv test flight outside, get a decent footage and learning how to do video overlay sweat.gif .

no fancy flying, just casually testing stuff. footage is from my 2nd batt pack flying this quad in full fpv. i probably need to use a different vtx channel. lots of static. rclxub.gif

I see lots of trees for cool obstacle flight with your quad racer.  I'm sure you can hone some speeding skill around the trees.  bruce.gif  biggrin.gif
*
haha...that's the idea. did a few rounds around the trees, was really tempted to go through the bushes, but i don't want to crash it sweat.gif .

still need some tuning before doing flips and rolls. still at stock rc rate. doh.gif the stock cleanflight pid was pretty good though. need more open space flight time before pumping up speed. nod.gif

Finally bought a Eachine VR D2 goggle. First FPV flight around house feel different, need to get used to. It stay just fine on my face and the footage from my KingKong Tiny7 is nice.
I bought the goggle for RM250 new sealed from some facebook page i found which is quite cheap and only takes 1 day to arrive since its just local postage.

bro how to check if the lithium battery kong or not?
*
batt tester(for multi cells) or multimeter. usually if a cell is damaged, it won't hold a charge as long as it used to.

if you ever discharged a lithium batt below 3.0v, there is a chance that it is damaged. (depends on cell quality.)

not lipo, i know about lipo
i mean li-ion

all lithium based battery works the same way. just with a little +/- in the voltage values. example, a good quality li-ion can go down to 2.5v and still be fine.

do note that mavic/phantom and the likes don't really teach you much in terms of flying the craft. those are aerial photography quad, so it does most of the flying for you while you take pictures/video. it's easier, but less thrilling.

it's like driving manual vs automatic.
