Suitable kv's for a Vendetta on 2S ?

I use Tamiya pinions on my Vendetta ST with a 430L 3550kv align outrunner motor. It's geared 19/45 on a 2s apogee 1500 magnum pack. With all the settings turned down on the quark 33, it still has tons of scoot. (<- that's my face every time I grab some throttle)

Ok, so I do know a little bit . I have 4 of the Align type motors, but mine I think are 3600Kv and I'm going to try something Eliica type R/C car, but instead of 8 wheels, I'll try 4 wheels first .

I've got a lot of hrs on my Vendetta and run 2S lipo. Breakage probs seem to start happening when you get above 3500kv. I run stock cvds in mine and other than having to CA the drive pins into the ends of the cvds have never had a prob - I did upgrade to alum outdrives, only other thing I've needed to do. Stock gear diffs won't take the higher kv. I got over 2 yrs running stock gear diffs using a 3500 CoolRed heli motor. Caught the ball diffs at 1/2 price and made that change just cause it was too cheap not too, but could have stayed with stock diffs.

I got some of the 1st DTX cvds came out that were absolute junk and are still bummed out about how lousy those were. Modded a set of cvds using alum tbg and rc18 alum bones buy have not needed them.

I've fooled around with hyperion 5000, golden horizons 4700 motors in my Vendetta and MQs (I have a total of 4). I have a feigao 280 on my bench as my next project with a quark 33.

280L 3500kv 45/16 is not bad for bashing
GH4700 is a nice motor at 45/13 for racing
but the best is permax 400/4D 5200kv which unfortunatelly is no longer made so my second choice would be ammo 28-35-5100.
L version of hyperion Y22 5000kv is not bad either

Vendetta uses mod 0.6 gears. so if you pick a 1/8" shaft motor like ammo you can use tamiya mode .6 gears.
for 2mm shaft atomic makes pinions and for standard 2.3mm duratrax and atomic

Oops. Subconsciously, I was thinking about my Trinity NOW, which uses Mod .5; my mistake. (It's sitting under the bed right now, and I've been thinking about running it all week, but the spur is chewed up)

I was wrong , but I was close and now I know something new .

To be fair, we were both wrong about something. And if I've learned anything from life, two wrongs make a right....sort of. Hehe (I made a funny!).

I'm always learning something new. I like getting new updates. Too bad I can't find a hole to plug a USB cale. I remember watching a show on the Science Channel of a guy controlling a PC with his brain.

I think I saw that, or at least something similar. One day that will be a reality; just download an "update" and voila! You're an engineer now! Our brain has freakish potentials. And now back to our regularly scheduled thread. Hehe.

Ah yes, but there will never be a way to update a slow witted person.

We could always try.

To bring things back on topic....
I found what I hope is a decent bundle from a reseller here in Sweden:
ESC: http://www.himodel.com/electric/HiMo...R-FLY-30A.html
Motor 5100KV: http://www.himodel.com/electric/HiMo..._B2040-6T.html

I hope it will be OK for my use, I need to get a few new pinions though, any ideas on what range to aim for ?

That motor's a little small for a Vendetta I think. The Vendetta uses 28mm diameter motors. That motor is 20mm. 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.

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 . Also, look into these: http://www.highendrc.com/index_ecat.php?cPath=8.

Sorry, I linked to the wrong one this is what I have on order:

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.
