I bought some balsa today and while I was in my local shop I saw 2 engines that I might be able to use- Supretigre G51 an OS LA 46. Both were RC versionsand both were the same price about $135.00. YES, I live in Thailand and I have many problems with getting things from overseas so if someone can inform me on how to convert them to Stunt versions I would be in your debt.
I have more to overcome as lines are not available and in the limited balsa supply there was no such thing as a block. Many things to overcome but I will make it.
Oh the other thing about which engine I might be able to use is that the only fuel available is some RC brew, probable little or no castor oil. This is all difficult for me as I am a Fox.35/johnson .35 man.
