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.

4s 14t for 95% of the tracks out there... maybe 15t if you just have sick long straights.. nothing like that in NY though.

5s 12t is too much with a 2200kv

Keep in mind you want just enough speed so that you are topped out WOT about 1/2 way down the straight away for max speed...

yea nothing to long on the straights here in jersey either. Maybe i will bump it up to a 14t and see how i like it.

5s wont happen till i get some extra cash.
also anyone that runs 5s do you think 5s 3000mah packs will do the job.

That 1600 isn't going to run well on 4S. So the 2000 would be a better choice.
