SC 15 engine
Howdy
I have had lost of experience with the super custom 15 engine, loads of power and reliable, there also really cheep!, about £36 quid from our model shop.
If you live in the UK i can mail order one to you.
They are really good engines, I have 4 in a royal B17, never had one stop, and they sound great!
cheers
