hi there everybody. ive been wanting to get a bigger plane and wanted to try gas but my near non existent budget (too low) wont allow me to go get an os gt33 or similair. i was thinking of trying a conversion and bolting it to the front of a hack trainer style plane. here are a few questions.
1)is it better to use a whipper snipper or chainsaw engine?
2)why? reasons for answer above
3) i dont want to use the fly wheel and i have access to cnc lathes and milling machines etc at school. i believe i need to use an ignition system. i was wondering if this (http://www.hobbyking.com/hobbyking/s...nes.html)would work. if not what would i need to make it work?
4)if that wouldnt work what is a cheap ignition system that would work?

i have experience working with small engines and regularly srip down pumps, push mower motors and carbies relatively easily. also if there is anything i missed can you please let me know. thanks for any help in advance.
