I am planning on building a 71" GSP Spitfire and am opting for the more ecomical 2str conversion engines. I have a couple of chainsaws I don't really use. Husq 335 xpt, Sachs/Dolmar/Makita ps401, Stihl 034, and Husqvarna 272XP. I may also be able to recover a Stihl 044 for its engine. Stored it away when it fell off the truck and broke the mount. Engine is still fine. I think these would be too big for this plane though.

Anyway, I want to put a conversion in the Spit, and guess the size of required engine to be around 25-30 cc. Does anyone sell a conversion kit for the most common engines? I read that a Stihl or Husqvarna Weedeater engine in this range would be a good choice. Are there mounts and things I need to make?? Which Stihl/Husqvarna engine would be the most powerful?? Where would I buy a kit? Where can buy the best electronic ignition?? Does someone provide 'plans' on how to do this?? I am interested in doing one, yet ignorant.

Meanwhile I will go through the forums and see what I can find. These forums are great!

Thanks,
