Thanks for the info! I think the adjustability of the MT2 just put it in the lead for me. I like the ability to change it depending on what I'm gonna be driving on. And 2+x more fuel doesn't sound very good to me. Thanks for the info!

Also, what size/how many batteries would be good to get for the roto start? I'll probably only be running about 10-15 tanks an outing tops. Would 1 3000mah be enough, or should Iget 2 2000mah, or what? Thanks!
