I'm getting 5.5 and 4.0 as every thing else is out of stock.
I drove Keefys SP5.5 and power is perfect for SMA... well for me anyway.
Ant, I'm going to SA title later this year. What motor do you use on 12th scale over there? Track looks very nice but hard to tell size from pics.
I dont know, havent run 1/12th since nats

I would say 4.0. Thats whats in it now

Track isnt quite as big as Whalan, but bigger than SMA. Its very technical. 23 sec lap times i reckon in 1/12th
