Hi Dave,
Im from North staffs,Yes I agree with your pricing. I have brought a spektrum DX5e combo for the tx/rx, And have done a bit of reserch with regards ESP, Power distribution, swiching and a flasher unit, Action Electronics seem to have an excellent reputation and also very helpful over the phone, So I think I will proberley go with their products.
The only thing i can not suss at present is the hopper release mech. I have got it to release and cut out, but not to reset / drive back, I think the diodes may be some form of back emf protection for the viper pcb ( its a very long time since I did electroinics), I do not know if this door release can be reused or as a new servo got to be fitted / modded. I think the viper release is more of a motor than servo,
i will post up spome pictures
thanks
Ant
