I think mrs losi racer should come up to the eastcoast and let Eric show him how to tune an engine! Monty that x7 you sold Eric has been his work horse this year.And nothing pulls it on the straits that thing just flat out hauls ass.Losi racer what ever! How about none nitro tuner that sounds about right to me.................For myself i run powerhouse engines and for some reason i most always finish in front of Eric!!!!!!!!!!!! I had to eric..lol.But Monty you make some fast ass engines Eric must have everything you've made and they do very well for him.I might even go with one of your x7's myself.Mark if you read this don't get mad your still the man
