Here is the Brillelli 26cc SS engine installed on the GSP Giles 202. Someone had ask about stand offs and any mods. There were no stand offs used as you can see. The distance from the engine box to the back of the spinner back plate is 4 13/16" and that gives you about 1" of the cowl to slip over the fuse. With all the mods I made with the CapX gear, no stand offs, Hitec HS-645MG in the rear and HS-635 on the ailerons the CG came out right on the money to the print. The cowl will slip right past the Velocity stack on the carb. These little 26cc SS/EI engines are packed full of power and will turn an APC 17X6 prop around 8700 rpm right out of the box. Tunning the engine was a little tricky for me but with a little hard work I think I've got it along with the fine support from Scott at Brillelli engines. Nothing like having someone to talk to when you need help with an engine and the boyz at Brillelli are top of the line when it comes to customer service. Not able to upload pics at this time because of the server at RC Universe but I will later.
