I didn't change much, I did not move the firewall, I did put the servos in the tail for the elevator and rudder and the batteries and radio behind the wing under the turtle deck.

The 16 oz smoke tank and pump are under the wing, the 16oz fuel tank is in the forward hatch.

I had to add 6oz in the tail to get the CG spot on.

The engine was a reconditioned ryobi 700r (short Shaft) from harbor freight $49.95, most of them haven't been run for mare than 5 minutes or so.

Muffler from Peter Faith at wackerengines.

I made the prop hub and mount.

I have less than $100 in the engine

I am very pleased with the performance and the reliability

I almost have a second one ready Cub Yellow with another Ryobi
