Good call John. That's what it looks like to me as well.

Thanks!! I looked at mine and thought it looked sheared off on both ends but it looked too clean and I didn't have anything to compare with.

I concur with John. I think he made the right call. I have a detail article about this exact problem in my blog. You could click on my name to read it. But you don't have to, because John had already pointed out the problem and you have already verified it. You could read it, if you wish, for more details.

Ooooh! I like the shape of that canopy!

And I was thinking about getting some of those CF S107G parts to replace the metallic ones. I like how the "stealth" heli looks.

I thought I'd post this here since this thread gets lot of reads, the S800G is bad if you want a cheap 4Ch and you fly regular helicopters. The Yaw is in the right hand like a 3ch and roll (slide left/right) is in the left hand.

Not a step up by any means in my opinion.

Well, even some hardcore 45 degree FP fans are now more and more moving up to CP, as the newer generation of flybarless CP helis are becoming more stable.

then we get bored (not me, i still favor 3ch heli and plane) and move up to 4ch where the first switcheroo gets diumped on us. whos bright idea was it to suddenly put aileron on ch1 and move rudder over to ch 4? of course most will claim its easy to learn all over again or say theres no reason to have 3ch models anyway. yeah right! this becomes really troublsome when going from 3ch heli with yaw on the rt to 4ch with it on the left (ie s107 to v911). then theres the move to cp where shutting down the throttle, instead of safely dropping to the ground, drives it 6 ft under. lets not even bring up the subject of rc cars, boats, and reverse. all caused by infatuation with mode 2 and noncentered ch3.

mode 4 eliminates most of the heartache and hassle by starting out with rudder on the rt even for 8ch models. so moving from 3ch to 4ch... guess what??? no change! of course everyone is entitled to their opinion but probably not worth arguing because few will even bother to read what ive said let alone ponder and understand the ergonomic advantages.

establishment hobbyists... cant live with 'em and cant shoot 'em. (well i spose you could... but that wouldnt accomplish much either. )

syma 107 (yellow)

Just a quick question. I bought 3 syma 107 heli's. One red a two yellow. They all have the signs of being real, not clones or fakes. Wiring is right, motors are correct, warnings....Question is I ordered a red and a yellow from battery superstore. The throttle on the yellow doesn't spring back as it should. I went ahead and ordered a new yellow from Planet Stuff, and the same thing, no spring back on the throttle. Can anyone possible tell me why?

Could be they sent you a used one where someone did the tx mod, and then returned it!

Mode 2 emulates the joystick flight control of a full scale warbird or video game simulator
Most RC pilots have never even flown a 3ch and to 90 something percent of the people, the 3ch is what's abnormal. I don't have a problem flying 4ch then messing around w/ a 3 ch. Brain just gets used to it. Like flying a 4ch CP inverted, after time, my brain does the work on it's own w/o me thinking. Thinking is dangerous, you mess around and practice until your not thinking about fingers and orientation.

The Mode 2 in the USA is entrenched. Just have to accept it or be frustrated with it.

At one point, I tried to make a 3ch yaw in the left hand to help my kids transition. you know what? It was a waste of time, my 8 year old transition in 1 flight to a 4ch coax.

About all a 3ch does it get you interested and maybe teach you to not bang sticks with the throttle.

If your having trouble transitioning to 4ch cp, your not alone, it can take some people weeks and months. Everyone is different. Having someone REALLY good or experianced at beginner setup to setup your heli.

hand made 3ch shaft drive mini heli

I started with the CF mods over a yr ago and the thing I wonted to do most is two make a s107 with a shaft drive. The first pic is the first attempt on the shaft drive. The forward speed was not what I expected so I put it up on the self as another failed project. Last month I started on it agene. This time I wonted to start from scratch and build a frame from used helis I hade lying around. The front motor mounts are from the s109, the back is from the s107 and the tail motor mount is from the flying fish mini heli. I will be using the s111 CB and installing the ZR-1GT kit. I will be testing the RPMs on the tail motor this week. I think it will be around 34.000. The tail boom and gear weighs out at 1.65gr and what you see now is 16.25grs. I am shooting for around 29 to 34grs complete.
