Syma Chopper fault finding

[Mr Mike]

I was given a Syma Apache 3H from a friend who had it for five years. He hasn't used it at all, so I have bought another Lipo (7.4V 1200mha). Although it runs extremely well when in the air, the issue the chopper has is that the signal/throttle cuts out for a split second every now and then. It'll drop out of the air like a rock obviously and this could end up breaking the thing.

 

What could I do to fault find here? Is this a common problem with these Syma's?

 

Thanks

Upon opening the handset, it appears someone has driven the aerial in too hard, this has almost snapped the solder joints.

I will need to repair it. Could i just drop some more solder on the existing stuff? Apologies, i'm not the expert here but i have the tools.

if it joins up the 2 parts then you should be fine.

Bugger. Turns out it's not that, or at least i think it's not that connection. It might have been a bit loose but now i've made a decent fix on there, the chopper still looses signal.

The aerial is wrapped around one wheel, is this how it should be? I did wonder if that was causing some issues but it might be a daft question.

 

It's a shame because when it is running it works well.

it has to be sort of straight   also what length is the antenna   as it should be around 40cm

It's wrapped around one of the wheels so it's just in coil. Where else could I run it?

under the tail hold it in place with small pieces of tape

I took the chopper out on Sunday, it hardly worked at all this time. The aerial was along the body of the chopper this time.

I think something might be really wrong with the radio signal connection. Either that or poor battery health? But I did charge it from new with a trickle charger that came with the Heli.
