I'm running a DLE 35ra on my GP GSS and if I get 4 flights an outing, I'm doing pretty good. Thanks for sharing.

I liked the Stihl Ultra 2-Cycle engine oil. No particular reason. I didn't do enough testing on different oils to determine which oil was best. I only used high quality oil, so there may not be a huge amount of difference between them. The engine bearings seemed to fail at about the same number of hours regardless of the oil used. I never tested Amsoil, or any ratio less than 30:1.

The only thing I really learned is that when you hear a clicking sound when rocking the prop back and forth, or if you feel a roughness when turning the prop over slowly, your bearings are bad. If you keep running your engine until the bearing race breaks apart, your engine will not be worth repairing.

Well, I guess we expected this. Tower has discontinued the Great Planes Giant Super Sporster.

I added another LiFe battery to my GSS, I never had any problem with having one battery, but there have been a few people at the field who have had one battery fail in flight. I now have two 2,200 mA LiFe batteries and two switches to power the receiver. The ignition is still powered from the Tech Aero IBEC plugged into the receiver for control and power.

I changed the fuel tank from 16 oz to 12 oz and replaced the fuel tubing.

Also, had a lot of problems with the tailwheel springs over the years, so I replaced them with a rod. It gives way better ground handling in the grass.
