Think of it this way - the software written for each profile has little parts specifically for that application. Example, throttle might be a little sharper for a 17.5 off road, compared to a 8.5 off road - hence 2 difference profiles. then if you use one boost - you would want that different. Then figure in that traction levels between on road and off road are different. So since you get more traction in on road 17.5 might be little more aggressive than 17.5 off road. The end result is the same - trying to get the most out of the system, but how the software gets from A to B (so to speak), can be little different with different motors, on road or off road, boost or no boost.

So if you put a completely different motor on the speed control, it doesn't run at all? Do the lights on the VPort still show that they are working forward to brake? If different motor and different sensor wire showed same problem, something could have happen to unit. PM me with any other details or questions.

Depends on your track - if its really big and open. 1900 is great high majority of the places I have seen.

2100 is a lot of motor for a buggy. It's more along the lines of a truggy motor. I run a 1900 outdoors on some larger tracks and it's plenty.

Ok, That explains it. Thanks Nick, I'll set the temp to 220 and leave it alone. But I will keep tabs with the temp gun like I've been doing just to be sure.

rut roh :blush:



:lol:

Turn your punch down lol

I have the 2100 in buggy and it's turned down and been racing it all winter and at motorama. I'll be getting a truggy when Mugen sells it so I'll just X fer the 2100 to it n buy new 1900 for buggy.

I see there is a update for the VTX8 (A64). Is it a good improvement? Is it a must have or.... Haven't been around for a while doing a huge home improvement project but I am finally getting done and getting ready for the season. Thanks. Using it a SC10 4x4

boborc here is the release notes on A64 give it a read i have it in all my esc's and they run as smooth as they always have, i have helped a few people at our track down load this into there esc's and they like it and i think you'll like it also.

I was running a 1900kv VF8/VTX8 in my EB48 tonight and it hit the motor temp cut off at 10 mins. I raised the cut off to 210 and lowered the forward power to 90% and got to 13 mins. It was about 60 degrees at an indoor track. I am surprised to see it hit those temps. My esc has A64 on profile 1. Brake strength 90%, brake pwm 16000. Throttle pwm 12000, punch 80%. Forward power 90%. Motor temp cut off 210 degrees. Also, using SMC 70c 6500mah 4s batteries. 16t pinion 44t spur. My drivetrain spins freely. Anyone have any suggestions as to why this motor is getting hot?

Try dropping a tooth or two.. Could be over geared

You are way under geared. I run a 19t on my 1900 in the eb48

you're '210' is closer to 140-150. The ESC reads the temps from the sensor board (internal). When everyone refers to temping the motor, they are usually referring to external temps. Last season my 8th scale would be around 150-160 depending on the day.

One of the best decisions I did make was to put a heat sink with a fan on the motor. I saw almost a 30 deg drop in temps :eek:

Way under geared. Start going up a tooth until you get to the point where the temp starts climbing again.
