I have a twist plug-n-play and was wondering if a OS .91 would be a good choice over the .46 evolution it comes with. Is it to heavy? It weighs around 10 ounces more I believe which seems to be a bit much I would think but some people are using Saito .82's and seem to not have a problem. Will the Evolution .46 3-D this plane? Thanks for everyones thoughts.

an os 91 would be more than enough power for that plane! and 3d would be easilt there. have fun!

This motor weighs alot more than the evolution though, is this going to be a problem?

Have you flown it with that engine - some fliers say it flys well as is. I have the twist arf currently flying with a magnum 52xls using an apc 12x4 prop. It flys very well. Try the 12x4 or 12.25x 3.75 props. I think the 91 would be too heavy - plane would also fly heavier.
