RE: Speed models Beretta
If we go to fly the Beretta we will make a video. So you can see it flies excellent on a 21 to 32 engine.
I have never seen flying the Beretta with a 40 pylon but heard that more people have flown with a 40 engine.
I think its better to use a smaller but fast engine on this model. I love to fly it with a 3,5cc engine.
