Hey, Thats Cool. I have not had any problems with my Epic .18. I am curious to know, what issues were you having? I have never tried an OS engine. Does the OS .18 directly bolt onto the CEN MT2s, just like the Epic? I would consider buying one. Sounds like your just as hooked into nitro trucks as I am. To be honest, I have 15 vehicles acquired since I began this hobby a year ago. I like CEN MT2s, XTM Mammoths, HPI MT2s, Traxxax Emaxx, For the quick RC fix at night when noise can be an issue with the neighbors, and just got my new Jato last week. I dont deal with pull starters though. Ive put either a roto start or the tiger drives onto the nitro trucks. I dont like playing the, "lets pull start the engine," game. What other trucks do you recommend? I have always wanted to get one of those Schumacher 3-speed deals, or I have heard some good things about XTM's new XLB 1/7th scale buggy. Thanks again for the info. I would like to hear about your opinions in regards to the Epic .18 vs the OS .18. OS is easier to tune? Sounds good to me.
