Well to let you know i did get it running today .. Hurrah ... took absolutely ages and i eventually used a cordless drill on the one way nut.
Having ran it for 2 tanks i gave it a quick bash around the garden on maybe 1/4 throttle and it ripped a wheel clean off about 5 minutes ago ... i didnt even get it in the air ... its flat ground !

What crap ... it didnt even hold up on the break in .. whats it going to be like when its fully run in and flying ... I hope the shops open tomorrow ..its going back to see what they say.
