Yeah, have been through the KO site and done various searches but have only found one profile for 2wd off-road and one for 4wd off-road. As there's no reference to the track surface they were used on it's not a great help.
I want to get testing with this speedo but as there is so much adjustment it would be useful to have a known good start point.

Hey Gaz,

Without knowing how many turns your motor is, there is no way for us to recommend anything for you. Describe your motor, your track and your gearing ratio to us, and maybe some of us here can help!

D'oh!
Going to be running a B4 with Checkpoint 11x2 or 14x2 on a bumpy outdoor astroturf track. The track goes from very low grip when damp/wet to very high when dry. Gearing for the 11x2 will be 21/81 (10.03:1) for a dry track and will be using the 14x2 on 24/81 (8.78:1) if it's damp.

Alright guys, just borrowed a multi settings adapter from a friend and am trying to figure it out. I haven't plugged it into the speedo at all yet, but it seems like I can set it to the profile I want and save it.

However, when I am trying to set it, it looks different, instead of saying FREQ XX it says like 3.98kHz. It goes from .93 to 12.00. Most profiles I see have numbers much higher than 12.

Any help greatly appreciated.

JoelV-
In the hand setting adapter, go to the screen that says "FQ. VIEW". You have this set to "ON". Turn it off and you will get frequency setting number rather then "actual" frequency number.

The difference is probably just the Hara's "special" program that comes pre-loaded in the ESC...

If you have the programmer, it doesn't matter...

Twister 2.1 has a temp cutoff that is kind of low for people's liking. Twister 2.2 has no temp cutoff, although it has been argued that the temp cutoff is just higher in the 2.2 from the 2.1 (if I remember right, about 10 degrees or so).

Try doing a search within this thread. Its been talked about for sure.

I don't remember what the temp difference is on the cutoff, but I DO recall Robert Morris (KO USA service person extraordinaire) et al saying that if the newer unit does get to cutoff that it HAS been damaged.

Also, somewhere along the way, I think off the KO USA site I got the instructions to mod the earlier units to higher cutoff spec--you just have to cut a trace on the PC board iir.
