I dont know how to test the kv of a motor if anyone does that could help eliminate one potential problem.
Good idea about the mismarked motor but it can't be the 42K limit because it happens at 32.1mph(GPS) on 12.6:1 gearing which is less than 30K rpm i think.It will repeatably hit almost exactly that speed before it happens.

Another option is the MGM 16024 I am waiting on my 2240 to run it, but I will let everyone know how it works as soon as it runs. I am also using 8s lipo.

Gustav 04.03.2006 01:08 PM
Yeah,please let us know how the MGM runs,the only thing that puts me off is the complicated programming,i hate reading instructions,the thing i like about the future -universals is the switches make programming so easy,adjusting timing,frequency,forward/rev etc is just a simple switch.

I have a 9920 so looks like i'll be running 20 gp2200s 'till i get this sorted (or a new controller:frown:)

'slow power' mode I would bet money that is your issue 5.5 inch diameter tires 20000 rpm and your gearing gives a little over 26 mph, your tires are probably bigger especially at speed. I bet the motor is stopping at 20K-24K RPM, repeatedly according to you I would find a local computer nerd and get that link program open and reprogram your controler.

do you have a programming cable gustav. You can look into it and see what is on.

Gustav 04.03.2006 01:29 PM
Yes got the cable,just can't open the programm,get an error message in German.

If you keep trying it and close everything that you don't need. It worked for me like that. I even get it some times when hooking it up. so have to plug and unplug a few times.

Weird. For me the programming software works flawless. Plug and play.
