As Qiw said, it depends on your environment. If there is a lot of other interference then MHz one would break down sometimes .....
For me I would prefer the GHz one..... Those interference won't care about indoor or outdoor one lah .....

Don't worry... MHz had been in the industry for sometimes.... so not so much to worry about interference.... if just fly alone... nothing to worry about... unless your neighbour fly too....

PS: if both frequency is not close... there won't be any interference...
Example: 72.34mhz vs 95.65mhz~~ (won't interfere)
72.34mhz vs 73.64mhz~~ (have interfere)

Surprisingly, the pitch gauge for 450 size can be used on 4G6 as well, heheheh ... no need to be so headache for dun know where to get it .....
Cliffang, did u do any tuning to your 4G6 ar? like swashplate levelling, blade balance & tracking ......

Compare the Walkera Tx and ESky Tx, like what you have said, way more better ..... but if use it on Belt CP V2, dun know which Walkera receiver is usable ..... hmmm ... must survey already

any walkera 2.4ghz with 6 channels or more should be ok for your BCP
if u import the 2801rx i think its less than usd40 + shipping ..
1 million times better than the stock esky radio .. hahahahaa


Added on March 25, 2010, 10:21 pmthe 4G6 is a CP heli so u should treat it EXACTLY like any other CP heli
just that it is small in size does not mean can simply hentam .. hahahaha
u can simply hentam la if u want but it will not fly aas well as it is suppose to fly lorr if u treat it that way ..

If USD40+shipping I think it is cheaper but the problem of the RX-2801 is you will need extra battery supply ....
Ok, I think I am gonna do the same setup like what i have did on BCPV2 but the 4G6 parts are way more smaller than BCPV2, have to take extra precautions ......

If you still interest to get 4G6 try to contact them lah, heheheh I think their stock just arrived this week .....

why would u need extra batt supply for the 2801rx ??
the BEC from the ESC should be able to power the 2801rx the same way it powers the esky rx ..
too many things on my mind now .. the 4G6 is not one of them .. hahahahaa
eventually will get it one laa ... eventually tongue.gif

Not so sure as I am still finding out but when I look at the spec of a RX2801, one of the terms is a battery supply of 4.8V for 1100mAH. This made me think that I will need another battery supply loh biggrin.gif

Anyway, I will take your words as I trust your expertise in this hobby tongue.gif

Cheh, eventually also mean indefinitely lah ......

You don't need extra batt supply.... the ESC should be enough to supply the RX....
All the ESC comes with an BEC which will supply 4.8v (min) or 6v (max) to the RX....
ESKY ESC is supplying 4.8v... Align is 6v.... of course the voltage supply depands of what kind of servo you are using....

Look into how your BCP ESC is connected to the RX and Walkera RX is exectly the same~


Added on March 26, 2010, 10:12 amJust like what QiW mentioned... whatever you did with your BCP before fly... is what you'll need to do to the 4G6...
Check:
Blade balance, blade tracking, swashplate balancing, pitch, flybar, throttle, any loose screw, any loose parts, servo travel, gyro sen.. take sometime to read on articles... and also how to setup your TX...

Try read this... although is somehow outdated... but the concept is still there...

actually not ALL ESC comes with BEC ... hehehe
MOST comes with BEC .. the higher amps ones like 80A and above MOSTLY DO NOT have BECs one .. depending on brand

but for small amps applications like 450-500 size helis or smaller or small planes like what i am playing now .. we use mostly around 30-60A ESC which mostly comes with BEC

my 450PRO runs with separate 5V BEC comes i dont wanna run 6V thru the servos which alot of kwai lohs claimed can prematurely kill the align ds410m servos

6V did killed my hyperion servo before....

Yeap, it is not recommended to over-supply or under-supply the voltage than the rated value. If you needs only 4.8V but you supplied 6V, there is a higher chance of electronic failure. Even though if it is still work under certain conditions, but this will definitely reduce the electronic life span.

Of course, life is not perfect so with little bit of tolerance, it will work as well. For 4.8V, 4.9 or 4.7V would still be OK but 6V I think it is too much.

The hyperion servo have a rating of 4.5v ~ 6.0v...
The only thing is... i used that for rudder servo... and that's the most frequent used servo in the whole heli.... as the gyro will be controlling it...

But... working at 6.0v which the respond time is faster and the tail is better...
bad side... if the servo over worked, it'll get killed...

You'll understand more when you are moving further into this hobby... and know about the servo rating...

Hmmm, perhaps I don't understand about the servo rating. But generally this is the rule to be applied in electronics. I think there should be a typical rated voltage instead of a range of 4.5 to 6, is there?

all servos have their working voltage range
most will say 4.8v-6v or something like that ... so it is up to u to decide which one is more suitable for your style
normally higher voltages = high performance ... but at the expense of lifespan lorr ... unless u get those new 7v servos ... super fast but oso not cheap la ... hahahahahahaa

for me now most of the common servos good enuff already ... abit slow on the tail still ok as long as dont buang .. hahahaha

daddoo... if you go to the LHS website... (rcsmart)... you can see the servo spec then you'll understand what i meant then...

Yes, just saw that and it looks like the higher the voltage the higher the torque. And usually they only provide the range and no typical value.

normally there is no 100% ABSOLUTE rule for these things altho i suspect there has to be an optimum working votage
coz normally ppl mix and match things .. so have to consider power supply for 1 thing may not be suitable for another thing .. so companies that sells these things will put a "working range" to sell

eg. if the optimum working voltage for X servo is 5.3v but your power supply already running other stuff without trouble at 5v ... how ?? they lose your bizness coz u will have to buy other servos that runs at 5v lorr
so they put a 4.8v-6v range so they get your bizness lorr .. hahahahaa
