Modified Tekin R1Pro

[DRIFT_BUGGY]

What cap did you use in the 1st post?
Anyone know what size the G11 Cap is?


Here is what Tekin said about using the R1 Pro in 1/8 scale on their Forum
The R1pro is not designed for 1/8 applications, period! However we know that people are using it in these applications so we are offering information to support it. It does work pretty well if you understand what needs to be done. We are working on the Rx8 which is designed for 1/8 scale. We are also working on 1/8 scale motors.

We started this thread just to save us a lot of warranty replacement costs on the R1pro since we know people are using it in 1/8, but do not admit it when they send them in for service. We can't really stop them so we might as well give them information to save us money and save them disappointment. Another reason we are willing to support the R1pro users in 1/8 scale is so we can learn as we go and see what changes need to be made to make the Rx8 the shiznit.

With 4s lipo or higher you must use a larger and higher voltage cap then comes with the units. The cap supplied is only 16V and can be used up to 3s lipo. It is a very impressive little stud, but only 330uf. Even on 2s lipo we recommend 2 in parallel with extreme loads.

We really like the Panasonic FM series. We are offering them in our online cart. You really cannot go to big, but 2 decent sized caps in parrallel is always better. Also critical to keep the leads short. Dangling them on long wires kills most of the effectiveness.

The BEC cannot supply very much power when it has to step down the higher voltages. You must use a separate BEC module and unplug the red wire in the receiver plug.

Many people report that the R1pro handles the 1/8 scales with no heatsink or fans. This is very dependent on your setup, traction and driving style. Outdoor temperatures can also have a large effect. A fan blowing on the solder posts can remove a lot of heat. The solder posts are very good heatsinks since they are directly connected to the power planes.

We have raced competitively in 1/8 buggy and truggy with the R1pro on 4s lipo. Geared to about 45mph and seeing around 15min runtime on 4s, 4800mah lipo batteries. 5s lipo runs cooler, 6s is pushing the fet limits and we do not have much testing at this level.

Please feel free to post your experience and ask questions. We will provide as much good information as we can. Remember this is not really the intended application, but you guys always push the limits and we are willing to support it. If we can not stop it, we might as well join in and learn from it.
