Would appreciate advice on wheter not to put a tekin rx 2050 or 2250 vs MMM 2200. I just bought the MMM2200 new yesterday and am contimplating on taking it back to get the tekin system. the lhs told me there were problems with the tekin motors blowing up. they are a huge hobby shop and sell alot of both. but berfore i install the MMM set up. I want to be sure i am going with the best system.

want set up to be versatile for mainly racing, but want to have casual fun with it to.

Set up is a 2.0-e buggy race roller
losi 5000mah 14.8 25c battery

get the tekin.

they did have problems with the first gen rotors coming off of the shaft, but they've fixed that now.

"problems with the tekin motors blowing up"

No such thing, only rotors that came loose.

Go tell them.

loose the losi battery too.

The 2200 is a lot of motor for a buggy. I would stay with the castle and get the 2650 motor. I have an rc8e with a Tekin 2050 system, and an SC8e with the MMM 2200. I just think the castle system is easier to deal with.

The 2200 is a lot of motor so get the 2650???

I have not owned a Tekin RX8 system yet (have the 1/10 scale systems) but have had 8-10 MMM 2200s since they came out. Bought em new and used. I've loved every single one of them and never had a problem.

However, the customer service at Tekin is unbelievable. The guys there are very easy to deal with, bend over backwards to help you, and are far above every other company in terms of service. Even if Castle was better (which I am not saying they are) I would go with Tekin because I know they will take care of any problem that may arise.
And they have worked out the bugs with their ESCs and motors so you will be good to go.

Tekin motors do not "blow up".

I have the 1900kv on a 4s 14.8v and it is plenty fast. I wouldn't get the 2050 unless you are running it on a very large track. The 1900 gets you better run times. I've used it on small, medium and large tracks with great results.

Tekin RX8 with 1900 or 2050 1st choice, xerun 80 or 150 amp W/Tekin 1900 or 2050 and or MMM/2200 2nd choice. Never 2650 unless your doing onroad speed runs. Sensored is better, Tekin and Xerun ESC's are sensored and Tekin and Speed Passion motors are sensored.

I run the 1900kv from Tekin. I also own the 2050kv and 2250kv. Never needed more from the 1900kv, usually turn it down a hair and still pulls wheelies on the dirt from a dig. 1900kv is what I ran at the RC Pro International Finals and there aren't many tracks larger then that one in the US.

tekin motors are all good, just dont get the ESC !! the RX8's have an Incredible Failure rate! at least at a few of our tracks here in Southern California, but the Motors are Dialed..

I can't see how the "incredible failure rate" is very accurate. I've had the same RX8 in my Losi for well over a year.

I can admit that we have had failures just as everyone else has.

I can also admit that there isn't another 1/8 system on the market that is as smooth and as controllable as the Rx8/T8 combo either.

C'mon Blade, even you've had an odd failure caused by a shorted sensor harness. Everyone is learning right now with 1/8 electric, even us.

1/8 E sure seems to be getting more popular around here. We have several drivers running both the Tekin and Castle MMM systems. Noone is reporting failures of either one now that they have worked out their respective bugs. I can't wait to get into the races with them since I have my buggy up and running now. It is funny how there are two sides to the setups. Those looking for more power, and those who want smoothness. They are not totally exclusive, but having power that you can't smoothly control is a problem. These brushless power systems make more power than you can get to the ground in an 8 pound buggy. Accurate control does make it easier to drive which can make for quicker lap times with less power. Tekin has the two motor sizes, the buggy and truggy bersions. Castle had 2 sizes, now they have a few more too. There 2200 is a Neu designed 1515 can which is more of a truggy motor, the 2650 is a 1512 can, with a shorter rotor and is better suited to a buggy. Higher KV does not mean more power. In the same can size, the higher KV can mean a lower internal resistance, so it will be snappier on the trigger, but it will also be a bit less efficient. Until I actually race head to head I can't say for sure, but I certainly bucked the trend by using a much smaller motor than most. My plan being less power, but smoother easier control. I hope to find out soon if it was the right choice. I did leave room to fit the Castle/Neu or Tekin motor if my little Medusa 36x50 proves to be too meek. ROAR didn't set a minimum motor size limit, did they??

Both systems are great, I have both. They both rock! I'm running the tekin in my rc8be 1900kv on 5s and it's very fast. If you have the extra money then I would get the tekin. You really can't go wrong with either system. Both produce insane amounts of power!!!

I would go with the Castle. I ran a 2200kv mamba monster in my 8ight-E and it work well. It was a lot of motor and had more power then you could ever want. I had to dial back the acceleration and adjust the throttle curve but in the end it worked well. I got about 16-18min runtime with a Thunder Power 4S 30C 5000mah battery pack running hard. BUT!! If I were to go with Castle I would go with there new 1512 1.5Y 1800kv motor with the Mamba Monster ESC. Also, if you can actually find a Medusa 1800kv motor those are my favorite. They are discontinued so are a little hard to find but well worth it for a buggy. At our track they were the ideal choice for 1/8th electric buggy racers.

Too much power = bad!
hard to drive.
