Default FX series speed controls are now available

If you didn't know already the FX's are out and winning races. These are the smallest brushed speed controls available and you gain in performance over anything out there.
Smoother more efficient and easier to fit into any chassis.

Hey guys....

I am currently updating all my electronics and am looking hard at brushless ESC's to replace my old GTB. The R1 pro looks great but I have a few Q's

*what kind of thermal limit does the ESC have (with no sensor wire I guess the motor temp is irrelevant).

*What's the internal resistence/current limit

*How does the speedie perform with the usual sensorless problems like "cogging" off the line and no drive when the chassis rolls backwards (you can always count on some idiot to hit you when you are having a flyer!)?

Cheers guys...

It was nice to meet the team yesterday at the iHobby show. The new R1 brushless setup looks great, and I look forward to seeing it released. Hopefully the "geek talk" was kept to a minimum for the non-geeks at the booth .

Thanks for taking the time to show us the products.

If you're running 6 cell the thermal limit is up there. I can't release the temps that I know without speaking to Jim first. I do know that we were higher then Novak. Seriously though this shouldn't be an issue unless you're running a super low turn motor on high bite carpet with no airflow what so ever on the unit. In other words, as long as you don't shrink wrap the R1 or stick it in a balloon you should be ok.

Internal resistance spec on the R1 PRo is:

0.00005 Ohms (brushed fwd mode)
0.00015 Ohms (brushless mode)
0.00015 Ohms (brushed fwd/rev , no motor limits while using 4 to 9 cell sub c.

R1 spec's are:

0.0001 Ohms (bushed fwd mode)
0.0003 Ohms (brushless mode)
0.0003 Ohms (brushed fwd/rev mode) again 4 to 9 cell sub c.

Both spec's also at 3s lipo.

As I'm sure you've heard or found every system is different with cogging,etc. I know that there are certain motor combinations what worked better the others.

The worst condition was when rolling backwards off throttle it takes a brief moment to get started again. This isn't so much a cogging feel as it is a slow start. The car I was testing with was a Fk05. If I was tapped around and it did roll back it took less then 6 inches or so to get back up to speed. The starts were really good. You could cause a bad start if you REALLY tried but you had to be a dummie to do it. If you rolled up to the grid like you normally would the start is awesome. Lanches off the line are great. The higher turn motors like the 10.5's and 13.5's are the worst of the bunch but again we're talking literally inches of a full throttle a main start.

Remember that the R1's are "sensorless" but we ARE sensing the position. We're using the windings for our "sensor."

One of my favorite combo's was the Orion 4.5 motor with the R1 out of all of the "non tekin" motors I tested. Second to that was Novak's 5.5r motor. Super smooth and great all around power.

I'm sure everyone will settle into their favy's when you get to drive 'em!

Cheers randy.. thanks for the feedback...

I currently run all novak 3.5-5.5 but plan to run only 3.5 under 5cell.

I also use a "launch control" type setup on my radio to give perfect starts every time so I think this will eliminate the cogging off the start anyway.

Will they have a heatsink option or will it come with a heatsink in the pack?

Cheers...

The R1 series doesn't require a heatsink. The solder posts act as a very efficient heat sink. So in theory if you did need to cool down your R1 you can either fan the solder posts or turn the r1's position so that it receives some air flow to cool it down.

I personally never found a need for a fan. The only time where I did run one was outdoor asphalt TC running 6 cell. Even then I never did thermal it I simply ran it as a precaution.

I have the FX-PRO's that I will be running this carpet season and it is incredible to note that even though it has the most fets ever in a speed control it still only takes up the same footprint as a micro spectrum Rx!

Thanks Tekin!

Question... How is the Novak 13.5 brushless running with the R1pro? Cause thats the motor I would be using. Starting to look into the brushless ESC's and Im very interested in R1pro.

Thanks
