Working on this combo myself. I'm going to use a Cline regulator and place two 14 oz. fuel tanks back on the CG. The Moki drinks a lot of fuel (2.5 oz per min.), short flights on the stock 20 oz. tank. About have the Moki broke in with one gallon of FAI fuel. Moved the elev. srevos to the rear, one each side. Someone suggested 3.5 deg. right thrust, the firewall already has 2 deg, so I add 1.5 deg. more. I will trade your 4600' for my 7200' up here in Laramie. If you have any questions, I'll help if I can.
Good luck
