RC10 Worlds Car - What motor are you running?

[HyperDunley]

Hi all. I need a motor to go in my worlds car and whilst I am keen to put an 8.5 in there, it maybe that's a bit bullish, despite the manual giving it a recommended gearing. It will be connected to a Reventon Pro and used on both outdoor astro and indoor carpet tracks.

I know I won't be on the pace compared to the new cars, but still would like to be competitive and have at least some speed...

What are you guys using in yours and how do they compare to modern day speeds? If you have any recommendations on motors too that would be great

Thanks
