RE: Balsa USA Eindecker with 25cc homelite
Hi,
Save yourself a lot of grief and use either CH Ignitions or Ralph's. (RCIgn1) He does a lot of posts here. Either of those are proven, easy to install, and the sellers offer great support if you have problems or questions. Also a lot of support here in the forum also, so don't worry about that.
Good luck,
AV8TOR
