I was running 3.6 on a small technical track in VTA meanwhile the Motiv guys were in the 3.8 range. Definitely try gearing it up...

Anyone experiencing fade on the V16 25.5 motor with 12.3mm high torque rotor?

Running 8 minute mains in F1 on a small 80x40 black carpet track. Motor never overheated, always running with a fan. Starts off great the first 3 or 4 minutes, then fade is quite noticeable. Never exceeds 150F. I'm getting fade as much as 3 or 4 tenths off my last 2 minutes versus my first 2 minutes. A bit more than I'd like.... I upgraded to a higher capacity shorty battery too so I know that isn't the issue. Timing about 55 deg on endbell and 3.07 gearing.

What is everyone using to set timing, check amp draw, etc. looking to start doing some motor work and want to get the right equipment.

On that same note, what is a good timing setting for 25.5 TC/VTA and 21.5 TC/USGT. Also amp draw, what am I looking for?

A little setback with planned R1wurks aluminum endbell/timing screws and long aluminum stator screws. There was some issues with the prototypes so they are delayed

What frequency do you set a R1 200 amp ESC for VTA?

You are over geared and over timed and at this point you need to have the rotor checked for strength. I run 3.07 gearing for 200' of full throttle. For carpet 3.6/3.7 is where I would start. 46 degrees of timing

I've never heard of anyone running 3.6/3.7 gearing for F1 in 25.5, even on carpet...

But I will try 46-48 degrees and possibly ~2.8 on my next outing.

Low. Most punch.

I run 88/27 64p for 3.26 with 55* degrees timing on endbell on black carpet and I just won our ROAR Regional race with this combo. I also have fan mounted.

Questions?? FDR and Timming Help for a 25.5

Looking for a little advice since never running a 25.5 motor before. Wondering what FDR and timing to start with on a track 95' X 48 with my 25.5'?

I currently run the 17.5 and 21.5 's with 52.5 timing and an FDR of around 4.7 on a track here at home of 82'X36', not too technical but a nice flow and they are FAST and coming off under 150 degrees. I see some of you are suggesting an FDR in the Mid 3.5's and a slightly lower timing. Maybe its a different field with the 25.5 motors and me not having experience with them specifically so could be these 25.5's don't agree with the way I set up the 17.5's and the 21.5's so asking for some help.

Thanks in advance......

Go back one page and check it out. 47 degrees 3.4 / 3.6 somewhere in that area
