You should have your throttle ch set to normal, not reverse. I don't know if that'll fix the problem, but I know when I had my transmitter setup with the throttle ch in reverse my ESC did some funky things.

Unless it's a Futaba radio, where the throttle is reversed normally...

I had the same problem about 1 month ago.i removed all castle files from my computer ,re-downloaded and problem solved. Mine also would not recognize reverse durring calibration

Woops, I really missed that.:oops:

I'll try that

Still not recognize reverse ( break) when calibration
firm ware 1.22

Do you have access to another computer ? I honestly do not think that its your esc. I could be wrong.try downloading the new firm ware 3.161 or whatever it is."look for errors before you finish"

Not fixed yet.
When I reverse the trottle to normal position on the Futaba it go backward and the red light is on on the MMM.
Still can't breaking with the transmitter.
How can I tell if a Futaba sending signal?
Steering:OK
Trottle: OK
Ch3: OK
Break ( Reverse): Nothing

I'll try another radio tonight

I just got time to work on this issue.
It appear that it'll not bo the MMM.
I tryed to calibrate the MMM with my old TQ3 and it worked perfectly.
So it'll probably be the Futaba 3PM.
I'll give you news.

Emaxx --

Sometimes the easiest way to fix a radio problem is to plug a servo into the throttle channel, and see what the throttle is actually doing. This way you can visually confirm exactly what the throttle channel is doing. This makes programming the radio a little easier.

When you say to plug a srevo( steering) in the throttle chanel, you mean once mmm is on or before open it.
When I hook up a servo to the throttle channel to see if it is working correctly, it would not even arm. ( normal I think since the MMM is hook to ch1)

No, just run the RX and servos with a battery. Plug an extra servo into the throttle channel to see what the throttle is ACTUALLY doing.

You don't need the MMM hooked up -- just make sure the servo moves as expected, i.e., when you hit throttle the servo moves one direction, and when you hit brake the servo moves the other direction.

Since I never use an rx batt pack, how can I power the rx with a batt.
Wich slot on the rx do I plug the batt. What voltage that batt it use to be. not my 4s pack I suppose?
Sorry for the noob Q.

Just like the nitros, use a 5 cell NiMH pack, or 4 alkaline AA's. The alkalines will be fine if this is just a temporary test. I would not use lipo because 1s is too low and 2s (or more) is too high.
