It's not a bad idea to keep a truggy tank around for your buggy if your running an Open event. Mixed nitro and electric, any powerplant goes type race.
I think its a ton off fun having so many different types of 1/8th scales running the same race. Kinda like old school real racing when cars were still basic and noone had them figured out yet. I think we're about to step into the best, most interesting club racing ever in the next few years. Electric, 2 stroke nitro, 4 stroke running together is going to be really interesting.
Hopefully the fun class tracks don't die off to the rules oriented ones.
A OS .28 XZ and truggy tank in a buggy make a real equalizer when your running against E buggies.
But it adds weight.
A 4 stroke with a huge cooling head and correct gear ratio would get way better fuel economy.
