Topic: 16d motor Blueprinting.
Well I am definitely head over heals for 1/24 racing at the moment. Much more technical in nature and they feel less like "toys" to me. A good blend between my racing and rc roots, and small scale "affordable" fun.
I used to build my own RC brushed motors back in the day (10 years ago). So I am going to be getting back into that some and trying to extract some performance.
This was a good article I found on basic blueprinting of the Pro Slot 16d, all the way through to some serious modifications!
