Hi Gang,
I have a big TH trainer I took out of the moth balls and after watching the video on the Nex-Star,
I was thinking of playing around with a 4 stroke.
Any good suggestions on the engine 2 or 4 stroke will be much appreciated
Thanks

Tower makes a 40 size and a 60 size. Which do you have?

I have the 40 on the Avastar and I think the next bigger one is a .46
I'm looking in the catalog now and I see a nice .61 and a .75.
The 75 should be good for that larger trainer I have
