I also have run a Trinity Extech .24 motor with a 2013 pipe in my Mugen Truggy. I actually thought it was a great mill for the price( I paid $200 for a new one) but recently the infamous cooling head breakage happened.

I still have it as a practice motor and it has almost 4 gallons on it. Runs like a top, getting about 10 min/tank. Tons of low end which is great on tight tracks but I get walked on long straight's (120 ft or more) by .21's.

If you run on a tight track that has short run up's to jumps you will love it. If you run on open tracks with long straights you will get pulled by .21's all day.
