RE: 50cc Ultimate ARF?
No problem
I think you will find that the 3 most used engines in that thread are the BME50, the DA50 and the Brison3.2. With the odd ones being 2 with the Fuji43 that ended up getting replaced with DA50's. There have been glow engines mentioned with promises to report back but no one ever has.
Most of the first flights start around page 10. My maiden I think is on page 12
Just pop in and ask whatever you want to, normally it's a pretty decent bunch in there and we do understand it's a huge thread so no worries about that
