Thanks for the reply.
The kit is good quality, just the language problem.[]
I have a Kyosho spit with retracts as well which flies beautifully, i thought of moving up a scale, an this is the kit i decided to go for.
I am glad to know that it is a manufacturing problem, rather than my building experience.
What sort of throws do you recommend, and also am i going to come across any more nasties on the way.

Thanks
