Thanks for the renewed interest in this guys. I still have not acquired an engine, I was leaning toward the MVVS, but sourcing and pricing are not as good as I had hoped.

Since this is still open to discussion, I have stumbled upon a few threads where someone has suggested using a K&B 61 Twister in a 3D application. I guess this is supposed to be a pretty light engine, about the same weight as a 46, does that sound about right?
Does anyone have any experience or opinions about using a 61 Twister in a 40 sized 3D plane?

Thanks,

David
