I just ordered one of these speedos. Am I going to be less than impressed until I get the ability to program it myself?

RC12L3a

can anyone let me know what is/are the difference(s) between the vfs1 and the vfs2??

I think the 2 has the newer updated FETs

From what I have seen on the KO website the VFS-2 is a budget version of the VFS-1 as there are less FETs in use.

Someone tell me, whats the deal with the programming function? Am I going to need that for sure or will it still work great with factory defaults? I race stock and 19t.

You are going to need to program the esc to get the most out of it. You can still use it at the factory default setting.

Hello,

I raced this weekend and the track temp was almost 60°C. Me and a lot of my friends experienced troubles with the VFS1. After 4 minutes the esc cutoff because overheating. I've a 415, we run 12T motors. My esc is not too close to the motor. How can I avoid this problem. Does a heatsink exist foe this esc? Have I got to change the program? Or put a fan?

Hugo... the esc is shutting down because it is getting too hot. there is a heat sink, but wont work as well if you are overworking the esc. also, check the gearing on your motor. if its off, it might overheat the esc. check your profile and if it is too low, lower the entire profile 3-4 stages at a time until it doesnt shut down anymore. a fan will help, but lowering the entire profile will help the most.

Ko Propo has addressed this issue by making the VFS-1 Competition edition. it has a higher temperature cut off and a trick carbon case.

ive only shut down the VFS-1 in 19T running a stock profile on a very hot track. (140 deg F track temp) you will be fine in stock (unless your car is really bad... i.e. binding drivetrain, way off on the gearing, etc) if you run into any problems. post here.. we'll help you out.

thanks hebiki, just can't see any point spending the extra $$ on the new version if this will still do the job.

Hello Hebiki,

Thanks for the answer, when will the competition edition be available?

I have a very similar Q to that...

Over the weekend I was running my VSF-1 on a large outdoor track with a 7 single and about 3-4 minutes into the run I lost power to the motor, if i stopped for a lap or so it would come back. So I am assuming I was just getting the speedo too hot? I figured the KO would catch fire before it would have a thermal shutdown but i guess not???
