Which motor T8 to go with Tekin RX8??? For revo
 

I have been out of rc for the last year or so and last I knew the tekin rx8 was the controller to have if you wanted super butter smooth throttle control (good for a bit of low speed crawling in trucks like the revo).

is this still a good setup? Anything better out there now?

What is a good price to pay new for this setup? I was thinking the 2050 T8 motor on 4s....

What would be a fair used price for this combo?

I would run 6s and something in the 1600-1800 kv range geared for around 40-45. Temps should be cool and the setup very efficient. It will also be a blast to drive!

Revo is heavy, you need a big motor + low Kv high voltage to be efficient.
Tekin T8 truggy 1350 kV + 6S lipo geared for 40-45 mph will do the job very well ;)

Nothing is wrong with this selection and it should power the Revo quite nicely!

A used price on a combo, around $200-250ish...

2050 is a buggy tekin motor :( It will overheat in a truck like the revo, unless you gear it for 30 mph :(

The Castle 2650 is a buggy motor as well and I beat the hell out of it in my old Revo with no problems and no additional cooling.

If he wants to stick with 4s, get the 2000kv truggy motor instead.

Im useing the T8 2250 truggy motor with 4s, its not too shabby! The same setup with 6s is way to crazy. Its still fun of course, but its a diff shreader!

Thanks for all the comments.

What makes the T8 2050 a buggy motor? I know generally the higher the KV the lighter the vehicle should be...but the mamba is a 2200 and is a truggy motor...so why would the 2050 be a buggy motor? And of course the 2650 is a buggy motor.

For the tekins do you run a lower KV motor than you would in a CC/Neu?

I guess 6s would be the best setup, just go with maybe a 1900ish kv motor and gear for 45 so hopefully it will be very efficient.

Now that I think about it...gearing down will produce more torque so technically wouldnt it be harder on the diffs geared for 45 on 6s with the same motor compared to gearing it for 65? I guess the more torque gets things moving quicker but on the same note seems like it could shred the diffs easier???

The 2200Kv castle is not necessary a truggy motor, in Europe with long tracks it's a buggy motor. No one here take the castle 2650Kv because it overheats in our 1/8 scale buggies on our tracks... Moreover the 2200Kv run more efficient than the 2650Kv anyway...
The 2050Kv tekin is a buggy motor because of its length and its weight. The truggy version is longer and can handle more power. Unless you gear your truggy for 30mph the tekin 2050Kv will probably overheat and run inefficient in a truggy, if you want a tekin take the truggy motor, low Kv and high voltage, like we said earlier : 1350Kv and 6S, geared for 40-45mph should be enough ! 5S 1700Kv will be good too...
Using 6S and 2050Kv will generate heavy current spikes, which will kill your efficiency, even with a low gearing... That's my opinion, the best to do now is to try, I hope you will find your good setup.
Theoritically, you have the same torque whatever your gearing, because the motor compensates the lack of torque with a bigger pinion by pumping more current. Anyway, the higher the gearing you will have, and the longer the acceleration to top speed will be, so strains on the transmission will be equivalent, but longer, so I would say that higher gearing means higher damages to the transmission...

I'm with free agent, I use a 2250 kV truggy motor in my Revo. I ran it yesterday and really enjoy it. I have to run 4s because of the tracks rules, but if you can run 6s, you can kv down and run more efficiently.

What would be a good combo to run if I want to alternate between 4s and 6s?

I would like to be able to run 45ish on 4s but then be able to run 6s geared for 50-maybe 60 but still be efficient with good torque/run time.

Is there a beefy motor out there that can do the above? Would a 1900 be ok or should I go even lower on the KV to get more efficiency and still be able to gear for 50-55? When not doing street runs I would like to have a smooth setup with some pretty large tires so I want to have a good amount of torque so im not running 200* when I decide to run larger tires.

I am debating between the above scenario or JUST buying 4 3s packs and gearing for 50ish so I have a boat load of torque and run time....

What would you guys say is the minimum C rating for the above setups? I have read the tekin is not quite as picky as the MMM with C ratings (as far as going up in smoke goes)

Thanks!
