Hi Stu,
I joined BBC two weeks ago after just returning to racing after 20 years off.
Lots of people I've spoken to recently can relate to your/our return story as well!
I too have a new B4.1 and have just made that leap to brushless. I must say it's a world away from racing brushed, far less hassle, far smoother power delivery and way more efficient.
Typically people are using 7.5-10.5 motors in 2wd, but I noticed when looking that cheaper or less well known brands do seem to have lower Kv ratings (RPM/volt) than the big brands top line/high $$$/racer spec motors. That means that 8.5T from one brand may be much faster or slower than another brand 8.5T, but look for good performance figures in the price point you can afford. Of course look for sensored setups, rather than sensorless, and don't get the cheapest speedo available (think too running hot/inefficient), pay a little more for a longer lasting unit.
I picked a big brand comp spec 10.5T, but it's rated to 4500Kv, so compares with other brands 8.5T on paper, and down the straight. It certainly performs well enough for me, and I've not messed with timing and speedo boost settings as yet.
I'd also recommend going to see or speaking with racer based shops, rather than a basher shop. Locally, MB models in Leeds have been great with me, and can't recommend them enough. Saying that, I have bought off Otley MS myself as well, but you need to know what you are asking as they don't race the stuff they sell.
Look forward to racing with you soon Stu!
