a guy wanted to sell me a 30 size pull start engine. I went home and tried to do some research on the pull start engine. I think there's 4 posts that acutally mention pull start but not enough info to make a determination of it's advantage/disadvantage. Then I did a search on someone that might sell pull start engines..The only ones i could find are for R/C cars.

I've determined if i buy this heli/engine, i'll be all alone with no support. So i dropped it and will stick with my OS 50.
