Baffling 9920 Programming Problem - Help!!! - 01.21.2007, 03:13 PM

I've got a stumper of a question you you guys -

When I converted my Nitro Kyosho Inferno to brushless, I took out the factory Perfex 2-channel, 2-servo "nitro" system, and I installed my trustworthy Futaba "Magnum Junior" T2PEKA 2-Channel FM radio, which originally came with a steering servo and a throttle servo.

During this initial conversion to brushless, I set up my Inferno with mechanical brakes, using a Y-Connector to plug in both a brake servo and a Warrior 9920BK. Set up this way, I programmed the Warrior for forward-only, and hitting "Reverse" on the transmitter throttle simply moved the throttle servo the other way, which applied the disc brakes.

Here's the puzzling Question - when I finally decided to run emf braking (motor braking), I removed the throttle servo and Y-connector, and I plugged the 9920BK directly into the receiver.

As per Mike's BK programming directions, I removed the red programming bridge, turned on the transmitter and reciever, plugged in the Lipo main battery and waited the "5 seconds" for the motor to beep to start programming.

NOTHING! I tried a dozen times, checking and rechecking everything, but the motor never beeped; even moving the throttle a bit didn't "signal" the BK to start the programming sequence.

So, just to check, I plugged in the y-connector again (with the servo plugged in and just lying on the table next to the car...

And instant, perfectly easy programming!

Frustrated, I removed EVERYTHING from the car, went to the basement and dug out the cheapy Kyosho "Perfex" 2-servo AM radio system that was originally in my Nitro Inferno, and POW, the 9920 programmed beautifully without the y-connector or throttle servo plugged in.

Why? Are there certain radio receivers that an electronic esc can't "recognize", or that ONLY work with a servo, not an esc?

Right now I'm using the Perfex AM radio, which glitches from the brushless stuff and has terrible range, while my nice FM system is sitting in a box, sniff.

What's up? I'm sure I could just order a brand-new radio system (my Futaba FM system is 4 years old), but what a waste of money if I'm missing something simple!

Help?
