[loyn]

Are u looking for tail motor (brushless)? I know Jet Hobby got some small size brushless motor. Maybe u can check it out.

u read my mind

ya brushless ...... but not the tail ...... for the main

those at JH is too low Kv for single lipo operation

ya it is difficult to hover or fly this little bird

it go all over the place and v sensitive

that is why looking at all the potential mod to improve its controllability

those Ang Mo did alot of mod and said it can fly as well as a cx lama

Yup u are right...really made me crazy when I tried to hover the first time.
Do share your ideas if you have made any mod to make this tiny guy more stable.

Yes, in the beginning, it was impossible to fly it. The moment you throttle up, shoot to the left. I almost wanted to sell it away, but then Christmas gift frm wify, so tahan and read the RC grps thread on all the mods.

The breakthrough came when I replaced the main motor shaft and head. The flybar had no binding after that, it cld see saw and pivot freely ie when you tap the paddle, it should bounce back and forth easily. That's the most impt thing to achieve.

Next, adding some wt to the flybar helped it not to shoot to the left so much, just a bit of cyclic right and quickly throttle up and I cld finally get it to hover. (I shorten the flybar too.)

Then came the flying itself -- constant stick inputs -- as some have said, it's like trying to balance a broomstick on your palm!

I can only still hover tail in -- can't fly it around and do fig 8s like some ppl can. Need a much bigger space to learn that.

Thanks for telling me. I have the same problem with you when this guy always shoot to the left and just not possible to get it stable.

Where to get the spares? You mentioned you have changed some parts?

I heard from this thread that some upgrades are coming in. Where is the shop? Do you know?

You can look at the "walkera spare part" thread for the contacts.

This are the mods I did on this little heli

1) swashplate mod to hold it in position
2) shifted the aileron servo in
3) heat sink for motor
4) balsa strip to strengthen heli frame
5) tape 4 in 1 to prevent vibration
6) wire at blade holder for strength
7) battery holder mod to load battery from the back for proper CG
8) servo link move in by one hole
