I am going to place and order and debating between these two Tekin motors. I'll get about 2000rpm more top end on the 2050kv (better for bashing?). If I want to race it I can just go down one tooth on the pinion to make up the torque difference right?

I've used the 1900 myself and it is TOUGH! In my opinion even it is overpowered in an Electric 1/8th scale! But that's what the class is about right?

Either way you are good to go, just make sure you get the buggy motor, there is a difference, but I am not sure what that difference is exactly!

Thanks. Yeah I was thinking the extra 2000rpm will be nice when I am running up and down the road. :-)

The 1900Kv motor works quite well. If you don't need special gearing requirements you should be more than fine.

Look at the motor's and see if there a WyE wind or a Delta Wind Motor. I know most are a delta wind motor which dont like to take timing to them according to Tekin so if you ever plan to race I would go with the 1y or 1.5y tekin. The 1y tekin t8 motor is for a truggy i believe in a 2050kv or 2250 kv rating thats the motor I would go with hands down, It will spin more then enough rpms and make w.e fast and efficient and you can add some timing to it for racing just use caution

+1 more than enough on the track.

alright i found what i was looking for in my r/c magazine. The 1900kv t8 motor is a 1.5y Motor, which is good and the 2050kv motor is a 2.5d buggy motor.


I would personally get the 1900kv it will be better all around then the 2050kv motor. If your looking for the extra power for bashing and possibly racing this motor is what you want. Tekin t8 2250kv 1y Truggy Motor, that motor will scream . If you want to see what im looking at to get this info on if its a Delta or Wye wind motor check out www.Stomerhobbies.com they got these motor's with the rx8 esc for $279.00

Hope this helps

That is good info. Once you mentioned the different winds I went to Tekin's site and sure enough the 2050 is a D wind. With that said I will go on everyones recommendations and pick up the 1900... As always you guys have provided great info....

So I tried to order the 1900kv motor and other stuff from Stormer Hobbies on the 1st. Unfortunately someone else got the last one prior to my order being filled. Since I did not want to wait two weeks to get my order I went ahead and told them to put the 2250kv in the order instead since they had those in stock. It is a Wye motor so that is good. The guy was saying that being a truggy motor it is longer and has more torque. He believes it will fit in the RCBe so no worries there. Which leads me to a new question. The stock Spur gear is 46t and the stock pinion is 15t. With the extra speed and torque how would you use the gears to tame it a little bit? Maybe change to a 48t spur and a 14t pinion?

What's the difference between a D or Y wind? The 1900 is better?

Right off Tekin's site, There's more literature out there if you care to learn More. It can get pretty confusing when u start to talk to electrical Engineers and they use all their fancy terms Lol.


On Delta vs. Wye wound Motors:

There are 2 different ways to connect the 3 windings in the motor--in a triangle (Delta) or in a “Y” (Wye). There are advantages and disadvantages to both. Tekin’s Delta wound motors (sensorless) have a big magnet, Tekin’s Wye wound motors (sensored) have a much smaller magnet so that they are approved for use in competitions such as ROAR and JBRL.
Because of the differences in magnets a 3 turn sensorless motor will not compare closely with a 3.5 turn sensored. For example, the Tekin Redline 362 sensorless is a 3 turn that rates at 6200 kV, while the Tekin Redline 3.5 sensored is a 3.5 turn that rates at 10,200kV.
