Hahahaha, it looks like you hate your POS heli a lot, you must be talking about "COM-PI"

try borrow another gyro from fellow flyer and try try lorr ... thats the only way to find out
i replaced my ex-POS heli gyro with another and it works properly

yup ... that com-POS heli really give alot of probs
luckily someone barter trade it with me ... put in forum cheap cheap oso nobody wants .. hahahahaaa

OK ILL POST THE VIDEO OF MY 450PRO HELI.

anyway this is my 250...having tail problem...i guess..or its just like that...better during idle up tho

http://www.youtube.com/watch?v=vk_iLyGcM0o

I cant see what is the problem with your 250 tail .... what's wrong actually?

hi every1..i just got a cb100 from lucky draw, have go through the thread and some of the link for beginner..now try to step out the 1st step by lift up n down the cb100...but the it tend to drift to left ..other than use rudder to stable it..what i need/shd do or check...pls advise. TQ

if you notice, my tail doesnt hold during pitch pump, but maybe that is the best for its stock tail servo

ok this my prob with my 450...

notice myloss of power when throttle up..

Welcome to rc heli hobby

I think it is normal for the heli to drift to the left while it is taking off, just go to a spacious area and lift up your CB100, but before you are going to do that, make sure you are good with the control. For example, throttle, rudder, cyclic ....... you can learn in a simulator and you can do so with the Tx comes with CB100.

Did not play FP heli before so I could not advise you what to check .... but what a lucky guy congratulations!!!

Added on August 14, 2010, 11:39 pmExactly the same symptom when I have my 4G6 (which is a torque tube heli as well) fly with stripped gear.

It will start with very nice lifting power but soon after that the power will lost if I push my throttle hard suddenly, until the heli totally cant lift up anymore and you have to land. The flight time is less than 3 min, and the voltage of the battery still have 3.9V.

This problem is gone when I replaced the stripped gear. But your case may not be the same although I can see the same behavior.

welcome to the world of rc ....
the cb100 is a very stable FP heli for its size ... just make sure the swash is level or trim on the radio till u feel it is level
do not fly too long coz it will kill the batt
after flying let the motor cool down til u can touch it comfortably b4 flying again ... this way u ensure motor have longer lifespan


the 450 looks like not enuff HS ... most prolly coz batt no power liau ... try borrowing some more poweful batt 30 or 40C from someone to test test
the 250 looks ok .. high HS requirement is normal for that heli .. hehehehe

btw ... damm danger la u fly that 250 in the house ... i can see almost crash into furniture .. dunno about camera woman scared or not la ... hahahahahaa

I am pretty impressed by his skill ...... WOW is all that I can say!!!

Qiw, I think you can forget about 4G6S, should start to look for V120D02 ..... take a look ... hehehhehe

the more i wait the more helis going to come out .. hahahaha
looks like walkera is ruling the small heli world liau laaa
v120 very expensive laaa .....

Roughly how much for this v120d02?

Hehehhe, I can just get the heli and some of the parts are compatible with 4G6, but not my first priority now ...... unless the heli is very cheap


An OHS in HK selling this for USD300 with 2801Pro Tx, about the same price like 4G6S ......

chinesejade asking for usd348 ... not cheap at all
now i still having PLANE FEVER .. hahahahaa

yah.... lost control for a few secs on my 250...this bird..very twitchy la...

But I don't think you want to buy the RTF from OHS. LHS still no one selling V120D02 .... maybe Walkera is not a mainstream here in Malaysia like T-Rex .....

If CJ is selling 348 then you better look for another OHS in HK, there are plenty of them. But your fever still persist, so forget about it at this moment.

Wonder how could a person can fever for so long, that virus must be very powerful to keep you fever all the time.

u try then u know laa .. hahahaha
but can feel fever level is down already ... slowly heading back towards rotary

heading back to heli? Were you trying to say this?

tryin to refresh my heli flying .. getting abit bored with the same old moves maa .. so must try and learn new ones lorrr

f***ing hate my trex pro.

the term to use is not hate .. it is to troubleshoot the bugger
from your video it is very obvious that u are loosing power when u punch .. when u lose power then rpm drops and u will lose some tail holding power for sure (video cannot the vibration coz not HD 50inch )
remove main blades and spin it up on the floor .. look for vibrations that may cause gyro to screw up but this has nothing to do with power loses when u punch
if u are using the align 35X esc .. the tones i used are 1-2-2-2-3
the soft start in the esc has nothing to do with your power lose unless the esc is faulty .. u will have to power off/zero throttle for more than 2 secs for soft start to kick in in the middle of the flight

like i said earlier .. try/borrow some known powerful lipos 1st .. 35C or better ... this was the problem i faced when i saw my PRO loosing power when punch .. now i only use 30C and above for my PRO but still loose power after lipos get worn out .. hahahhaaa
i might be changing the motor when i get the chance .. the 450M sucks too much power laa
