Default Tekin motors any good for top speed runs?

I've very rarely to almost never see anyone use tekin motors for speed runs. Do they not make enough high end power to go very fast(100 mph+)?

They most certainly do.

The main reason why I ask is because I have a Tekin Redline gen 2 5 turn 8550kv motor but no sensored esc to run it.

The car I am considering puting it in is a Team Associated TC4 speed run car that has gone 126 mph with a castle 7700kv 1406 motor with Mamba Monster 2 on 4s.

I don't really want to buy a Tekin RX8 gen 2 to run the motor just to find out that I just made my car slower! Haha

I have 4 cell and 7.5turn speed passion motor and my car maybe goes 80 to 90 at most. I don't know how the other guy got it to go 139mph when I'm only at 80 mph.

Maybe better to start a new thread but 90+ is achievable with a 2s Lipo and 3.5T.

You could also use a Mamba Max Pro as an ESC for a sensored motor.

I've tried a mamba max with my tekin motor and it does not take off smoothly if I give it too much initial throttle. It would actually bog. I tried 2 different mamba maxes and same thing happens. Plus the mamba max pro only puts out like 65 amps.

High speed runs really need to be thought out a bit. Running 2s holds you back right away as the low voltage means high amp draw. If you plan to run 4s you really need to consider what's going on at higher votlages and what the motors are able to do.

If it were me, I'd be looking at 3s(for weight) and the RSX on a Pro2 4 pole motor. Carefully and I mean carefully build up gearing and the setup to make use of the torque.

2 pole motors do indeed hall the mail but they will lose the torque game to a 4 pole every time.

Looks like the pro 4 motors come in 4600kv max. On 3s im positive it will not be faster than 126 mph. Even on 4s geared up to the max it won't.

I'm at a point rite now where nothing I have tried including different gearing and batteries is making me any faster. The only thing I can think of that would make it faster for sure on 4s is a Steve Neu motor. Im just hesitant to spend the $200+ for one.

Listen, call up Jose at Cordova Research and tell him your pains. He will build you a custom motor to satisfy your needs (619) 730 4983.

You've got to understand that what type of aero effects you're dealing with also. 120+ mph in an r/c car is no joke.

Our Pro2 motor goes up to 5800kv.

Im currently running an HPI F1 McLaren body but its getting pretty beat up. I was thinking about trying a Pagani Zonda body which im pretty sure I could pick up some speed with.

I actually gained 8 mph a few days ago in my OFNA GTP2E from just switching from the stock McLaren body to an Ipanema Warrior body. Went from 112 to 120 mph.

Didnt know the Pro4 was available in 5800kv. I've tried a Castle 5700kv 1406 motor and was only able to go 116 mph.

I personally would suggest using a higher Lipo setup, maybe with a Castle XL2. Since Power=Volts*Current, the greater the volts and amps, the greater your top speed. I don't think weight of the car should be an issue, it may reduce the acceleration, but not affect the top speed.

For the body, check these

Lipos and BL's have "democracized" speed and power. Pretty much anyone with a can go 100km/h++ in a 3-4lbs toy car now/ That's a crapload of kinetic energy which used to be available only to 8th onroad not so long go, and not everyone was/is mechanically savvy enough to manage these beasts... Cheap Go Pro's and clones, plus youtube have added fuel to the rc top-speed wildfire.

Be afraid. Be very afraid. And watch out for the headlines until the first BIG accident happens and a sue-happy nation awakens.
