RE: YS115=December. Need Engine Sub Advice
i have both the Saito125 and 120 AX. the Saitor would be a good choice if have lots of 20-30% nitro fuel. the AX is very strong and very light (lightest 120) bone stock will pull an APC16x8 at 8,600 or put a Jett 120 muffler on it and hit 9,600. close to same rpm with Xoar 18x6
