selling emaxx for buggy

[tha5150]

new to the buggies. i had an emaxx i started out with for a year now and getting sick of it. i have a friend locally that just got one and now i am hooked. plus i just found a race track right down the street. looking at a few different ones to convert to brushless. Ofna 8 Hyper, Ofna Hyper 8 Pro 8.5, 8.5 pro, Losi Eight and another 8 Hyper Main.

not sure the differences in all of these are but i would assume the higher number means the newer the model.

anyone have any advice on either of these?
i understand all i will need to convert is a motor mount from Mike and a battery tray from Losi or Mike. is this correct?

what kinda speed/torque can i expect with a MMM and Fiego 8XL????
