I flew the one on glow with an O.S. 48 fs, Super Tigre 45, K&B 65, O.S. 70fs. So you do not really need a lot of power for it. If you want to have a ROCKET Cub, sort of like a Super Sonic Turtle, use:

Prop, APC 16X8.
Will make the plane go almost vertical with about 10 to 15 minute flights with just cruising around doing T and G's I have this setup in a Low Wing Trainer I use to haul gliders up. It has plenty of power. If you want a more sedate type of cruising around. Go with the Tacon .46 and a 13X6 prop 5s 5000 battery.
