Hi Mike,
any news? Some time ago you mentioned it would be on your site but as far I can see nothing has showed up yet.

Thanks.

I think I'm going to do this too. Not in a big hurry, I'll run the gas motor until everything is ready, i.e. the esc and conversion kit. I'm thinking, since Mike is having good results with the 1527, of going with the 1527 1.5/Y on 8s. The problem is on Castle's site the motor is $302.00 shipped.

Anybody have links to some good boat forums so I can start searching for a good used one?

Also, Mike, how do you think the Castle 1717 would do, would it be enough?

1527 for $260

I will post updates as I have them as far as the conversion is concerned - been a bit swamped lately with various things, but these kits are coming along and will be ready very soon.

I think the 1717 motor MAY be enough IF it was a 2y instead of a 1Y - I couldn't say with any certainty without an actual 1717/2y motor to test, though!

The 1717 would be borderline, though - the 1527 is proving to be borderline - with a 12t pinion and no heat sinking, it can get pretty hot when I am beating on it - with 7s and 8s it works great but I can get the motor up to 160F or so near the end of the run. I will add heat sinks(2 losi heat sinks fit nicely) and see how it goes and maybe add a fan(or use the ESC fan, as I haven't even plugged it in yet - the 1527 motor is the limit and not the ESC so far).

For 8s or less, the motor really needs to be under 1000Kv IMO for best results. Sensored/hybrid would be great in this application due to the gearing - stock Baja is designed for a 20k rpm motor, so there is a bit of load on takeoff - small pinions are ideal. The ESC is working terrific as it is - but with aggressive gearing, it will cog a bit on takeoff (I use 12t pinion and it is awesome, but I have run up to an 18t pinion and it cogs on takeoff with this gearing(and the motor gets hot pretty quickly - need more motor for aggressive gearing). I think a 1527/1.5y with a 1.5" long 8mm shaft and heatsinks will be a great setup for most users. With short gearing it works extremely well, is a lot of fun, and still gets near 50mph(borderline too fast for this beast unless you have lots of space).
