which motor for my 8ight t
 

Well I got a losi 8ight t I plan on doing the rc monster mount with a losi battery tray.
Question is which motor should I run. I really like the medusa research motors. Or I can take. My 2200kv motor out of my buggy and buy something else for that also what size medusa should I go with.

Thanks for your input I will be running this off a mmm esc. On 4s and 5s batterys.

Medusa is out of business w/ motors now from my understanding.. Typically truggy drivers go for a 1700kv ish motor w/ a 5s lipo config. The 2200kv Monster will do the trick though if it's not needed in the buggy. Just make sure you have GOOD 4s lipo's that can take a ton of draw, junk packs will die quick in Truggy setups.

I run a RX8 2000 combo in my 6T on 4S. It's real reliable.

I used Brian G's calculator to determine what Tekin system I was going to buy. I configured it out to what motor I needed by finding the right rpm range for best efficiency. The 2000KV on 4S is 30K rpms. Perfect if you ask me. Low temps and great run-times geared 46:16.

Hope this makes sense.

I run the MMM with a 1515 2.5d on five cells geared 46/16 with my 8t 1.0 and that's all i would want to run everything run real cool.

Problem is them neu motors are so expensive. I think I will just use the 2200 castle motor on 4s and 5s. See how I like it.

Pick up a Tekin 1700kv Truggy motor and run it on 5s. Not as expensive as Neu.

I wouldn't bother with Neu motors either, myself. My 1512/2.5D/Q just crapped out on me after a 5-month life of sealed screw holes and temps under 160dF. I've never seen anyone have problems with the CC/Neu 2200 motor, though. It's the standard motor for 1/8th scale, as far as I'm concerned. 5S would be a bit much, but having the option to just switch batteries (4S for racing, 5S for fun) is a major advantage over being locked into a lower kv.

yea i decided on the 2200kv in there. i am going to go with a 11 or 12 t pinion.

Anyone know the recommended RPM range for the 2200kv Neu/Castle motor?

30-35k rpms for best efficiency.

Excellent, so looking at the calculator then with my proposed 15/48 4S setup then it says it will be 32500rpm....should be spot on!! :yipi:

that would be good i believe.

14t is enough on even big tracks w/ a 2200kv motor on 4s lipo, anything more just reduces run time more than anything so be careful. Wheel bloat needs to be calculated for top speed +1" w/ truggy tires at WOT.

i feel the speed isnt there running 12/49 in my 8ight t. seems really slow compared to my buggy. Maybe it is just that it is a truggy compared to a buggy. The buggy i have geared with a 17 tooth pinion. And it is just plain outright fast.

The truggy seems slugish on top end. Like i am only getting maybe 25 mph not enough for my taste on straight aways. I am going to play with gearing once i get it back together hit the edge of a curb and broke some stuff. Oppps.

so on 4s and 5s which would you pick

Medusa
36-70-2000kv
36-70-1600kv

Again these will be run on both 4s and 5s.
