I know this has been discussed before but I have search and search and can not find a answer. So I am going to try and see what I come up with.
I just bought a M8 with the Spektrum tx. When I bind it to my losi receiver everything works but the MM just blinks. So when I add a little forward throttle to get it to activate and i let off the throttle it want to go in rewind. I have adjusted the throttle trim both ways it still does the same thing. I have tried everything and it does it on both of my Castle speed controls. I have read on different forums about this happening but no one talks about how to fix it. Also a couple of forums said to calibrate the Losi rx. I have looked everywhere and can not find out how. Every help will be appreciated. Thanks in advance for any info.

Reset your speed control to your new radio. You bound up your receiver and its ok, but you have to setup your speed control through the basic setp for your speed control, its in your manual i beleive its full throttle to full brake then to nuetral position. You have a castle creations product you will have to reset your speedo to your new radio. its in the manual for basic setup.

X2... But you should set your throttle epa to 100% and full dual rate on your TX before you go through the ESC setup, this way once your ready to drive and tune your car/truck your baseline is "full" and the TX adjustments you make will work and make sense!

Ok guys thank you I will try that when I get home today. Thanks again for all the help.
