just were have you seen brushless 5B's running around? If it was done by Fine Design then yes it was probably not that fast and not that great. Stock 5B's only run around 40mph out of the box, you know brushless will be faster then that top end and take off, no way a gas will hold a candle to brushless. I'm talking neu 2215 on 37 volts, not a 1515 size motor.
lipos 220.00=10s 5000 zippy, I have seen cheap 100.00 esc work on the baja from across the pond. BL is so much cleaner to work on and bring into the house for those really bad repairs.

Now I am thinking of a conversion for the baja...

Wondering about a few things. How are the pinion gears held on on the stock clutch setup?

Also, since it is 2wd, I wonder if a 10-12s setup with lipos capable of 100amps would do, along with a 100 amp or so plane esc? That would be about 3.5hp factoring in around 30% loss. Is that enough? I can't imagine the 26cc motor being good for much more than that. 40mph is fine for me, I am in no need for huge speed with this beast.

How about a pair of 1521 motors? I know pairs are usually frowned upon, but I have everything here to do it, save for some cheapy speed controls.

What is the gear pitch on the 5b pinion and spur? Looks big, like 1.5 mod???

Yup, it's Mod 1.5.

Maybe I was wrong on the quality of the KM Bajas, then...though I'm sure I read of one guy having issues. Still, I'm not sure I'd buy one. IMO, it's clearly an HPI design, but I don't know...it just doesn't sit well me me.

Back on track, though...I can't believe Chris Fine is still in business! Castle should stop supplying him with ESCs; the number of them that his customers have blown because of them being used in the wrong app, or over-voltage like in that ad, must be huge. It'll be giving them a bad name.

I've only seen brushless 5Bs on youtube and I haven't been impressed with any of them. Maybe I'm looking at the wrong ones

The Neu 2215 is $425... You said it would be good on 37v, how much are we talking for the rest of that setup?

I agree that it's cleaner and not as noisy. But when you're talking about battery powered vehicles the cost for performance ratio gets pretty bad when you start making them big. Currently, the way I see it, is that brushless can't hold a candle to gasoline in terms of value for 1/5 scale.
