I just finished my Ultra Stick 120 Lite. I haven't flown it as yet as the weather has been very wet. Maybe next week. Here is what I did if anyone is interested.
1. Zenoah G26 - RC Ignition removed the mag and installed a battery ignition.
I removed the back plate and installed the engine with 3 8-32 bolts,
I also added a 3/8 inch firewall to the exosting firewall.
I added a Abel muffler
2. Servos - Futaba 3004 on airelons, flaps, and throdle,
Futaba 3010 on rudder and elevator - installed in the aft
3. Everything else - 14 oz. fuel tank.
Du Bro pull pull on rudde
Jersey Modeler fueling system
Tank under the wing
Battery and receiver under the wing
CG is at 4 1/4 inches from leading edge of the wing with no aditional weight added at
either end.
CB/Tatone rear wheel

Here is the best part - It comes in at 11 to 11 1/2 lbs.
I'll put in flight info if anyone is interested.
