Cutting weight from G20I with dremel
« on: January 21, 2012, 10:17:40 PM »
Does anyone have some ideas on how to cut some fat from a zenoah G20. I love the little motor and I am doing everything I can to get more out of it

Not a whole lot of weight there..I customized one by turning the cylinder fins down and cutting the threaded bosses off the front of the case..Took the prop hub off and replaced it with one from a G26, a little shorter and lighter...Cut the rear of the crank off flush with the bearing and replaced the crank seal with an aluminum plug...Put an RC EXL ignition circuit and coil on a plate across the back of the case, inside where the crank extension was...Had to leave the advance part of the ignition off because of space limitations...Weighs about 2 lbs without the muffler...

 I have one with Ralph's handiwork all over it and it is a dandy. It uses a regular RC exl ignition and weighs 35 ounces including  ignition and a lighweight alum. muffler. With a Frank Bowman's ring and turning a 16x6 prop it runs like a raped ape.
