You could try this one http://www.lightflightrc.com/HTML/pr...RC-28-47-1.htm. It has a 3.17mm shaft, is a 4 pole and the magnets are wrapped with Kevlar. If any of you go with them, tell Dave I mentioned his products to you guys :lol:. Also, look into these: http://www.highendrc.com/index_ecat.php?cPath=8.

Wow, that's one freak of a motor in your first link. Probably has tons of torque from the 4 poles and it being 47mm long. The second link isn't working for me though (or it's just taking a LONG time to load, but I'm on a cable connection here at school, so it should load relatively quickly).

I heard the plane guys are using that motor for up to 1000W in their planes. Try this http://www.highendrc.com and look for the Brushless EDF motors, not the 600 though.

Link's still not working. It's trying to open the page, but it's taking a VERY long time. Still hasn't opened it yet either. I'll try later and see if that helps.

1000w is crazy out of a small motor like that. What the heck do they use it for, pylon racing?

Edit: Link works, just took a while to open.

I don't think that little guy will be able to handle the heavier Vendetta without overheating. It's even shorter than a mamba 25 motor by 5mm, and I'm pretty sure even those guys have issues with the larger minis.

If you are set on using that setup though, I suggest starting with the smallest pinion, and working your way up. You probably won't be able to run too large of a pinion with that motor at all. Now that I think about it, I'm not sure how it's even going to bolt up to the Vendetta's motor plate either.
Sorry, I linked to the wrong one this is what I have on order:

I think that guy testing that motor was uning it in a EDF plane. Here is the link for more info: http://www.rcgroups.com/forums/showt...630759&page=69. Look at post # 1022 and the guy said 1300W, by his calculations. Post # 1008, Dave even mentions another motor on 8S that draws 1100W.

Much better size wise. I'm betting it'll be a handful to drive. It's definitely not going to be a slow vehicle at all. Max efficiency is only 81% though, which makes me question whether or not it'll run hotter than most other motors. It's a cheap combo though, so I think for 50ish bucks total to go brushless, you still can't go wrong. Nothing a heatsink can't help keep in check probably.
