WJ i flown the smaller revolver with a high than standard weight of around 8 lbs or so. No issues at all I think it was a very easy plane to land i never ever had a tip stall with any of the small ones i owned. I heard of people saying they cant slow them down or the tip stall all the time.

I think the SYYSA would be the faster engine in this plane just wonder what kind of speeds others are getting with these engines. If the 30 are an easy fit then maybe i should go the next size up in gas engines like a DLE55 / DA69 or something.
