I got the motor sorted out in the end. Well I think I have, 1/4 balsa and lots of epoxy, this I may have used too many micros ballons making it very brittle. However it feells really sercure. Just this damn weather.

That's my next 2m I'd like to get, the impact, whats it like post some photos. How much they for us once the conversion is done.

I'd say go for Hacker, more power.
