the OS .18 will make a night and day difference. Its ability to let a NOOB tune it, blows away any other engine company in the industry.
Woo you are recommending an OS and a .18 in a stadium truck? Sorry just had to say that and I understand what you are saying. Sounds like an air leak to me as well. Some are not cut out for this hobby. Not saying you are one of them but.
