Questions?? Difference in Tekin R1 & RS

What is the difference between the R1 PRO & RS PRO? Only thing I can see is the RS can be used with Sensor Motors and the R1 can't?

You're correct as far as I understand it. Here's a jumogous thread on the RS in the onroad forums.

They both can be used with sensored and senorless, just the RS can also make use of the Sensor port on a sensored motor.

Also, the RS can work in fully sensored, sensorless and a hybrid of the two.

Just to add the RS and R1 are both sensorless based esc's which can take advantage of working in sensored or sensorless mode.

One important point on the RS is that it is ROAR legal.
If you plan on attending a ROAR sanctioned event you need the RS. The R1 is not legal as the rules are now. Both are great controlers. The insides are virtually identical. Advantages include small foot print for mounting in the chassis. Great heat disapation. Smooth operation. Very tunable. low low on resistance. And for practicing you get the option of turning on the reverse to save walking off the stand in the rare instance you get stuck on a pipe.

The RS and R1 are both roar legal. Its just that the slotless sensorless motors aren't roar legal.

R1 works in sensored mode?

The R1 and RS are not illegal to begin with. Motors is where politics come into play

Eveyone is right. The esc's are all legal. The motor is where the legality lies. The motors (Currently) have to be sensored in design.

The R1 is a great controller. It does run all brushless motors, some better then others. If you're looking to be able to run any motor flawlessly 100% of time, pick up an RS.

The more I look at the Tekins, the more beautiful they are. The fan-less, small form factor is really attracting me towards these systems. Is there a large leaded electrolytic tagged onto it like the Novak GTXs?

Also, what's going on? These things seems to be backordered everywhere I look... I bet you guys are probably back logged quite a bit due to high demand for these eh?

Tom,

There is a small silver cap that is required. It's about the size of Lego mans Head(don't ask, lol). I solder mine directly onto the solder posts and forget about them. They're tiny.

The only environment so far that has required a fan is heavy mod TC. Some of the euro guys that run offroad on the carpet and grass with sealed bodies opt for them too.

As far as getting them, there are a few sites that seem to keep them in stock. Check out the RS thread in the onroad section, they tend to post when they have them in stock.

I use the R1, and RS, both work flawlessly. I really cant tell which one is which when they are running. My R1 has a Redline 3700kv sensorless motor, and my RS is teamed up with a sensored 13.5. Really, I'd say if you plan to run a 17.5, 13.5, or 10.5 get the RS, since the R1 while it will work, may not be the smoothest on the start-ups. Check out www.stormerhobbies, or www.ampdraw.com for Tekin ESC's.

The RS greatest asset for me is the ability to make adjustments via the Hot Wire, such as Timing and drag brake. The small size is great for easier mounting in tight areas. I agree with an earlier post. Mod, you can go with either model but for stock classes run the RS. At our track, the stock motors still cog a little with the R1 especially in Offroad 1/10 scale, for some reason the mod's do not.
