Brushless into Old Skool Models

[rasher]

Just after some advice from you guys who have converted your vintage runners to brushless.

Looking at dropping a Brushless Setup into my vintage XX4 for the A1 Iconic. Just about solved the Lipo Pack installation....(got a bit of carbon work to do).... but not sure about motors. I used to run 11T or 12T Doubles at the back end of the 90's but don't really know which brushless motor winding would equate to the same kind of RPM.

I have a 6.5T I can drop into the chassis but thinking it may be a bit hot! Don't really want to tear the old girl apart at the seams!

I was thinking maybe an 8.5T or 9.5T may be a bit more suitable..... especially seeing as I haven't raced for a few years now.

Anyone have any kind of advice on old windings compared to new windings and RPM?

Cheers.
