Got my Corona on Saturday. I'm about halfway through the build process. Everything is going great.

I did run into a snag though. I wanted to test out the motor and wired everything up on the bench. The manual mentions that, for safety, you mus arm the speed controller before it ill allow the engine to start. The manual mentions that you need to move the throttle stick and trim lever on the transmitter to full low for two seconds, then middle position for two seconds and then finally full low again for two seconds (waiting for a beep from the motor after each step). Unfortunately, my transmitter is computerized and the trim settings are digital. There's no fast way to move the trim settings to either position. As such, I'm not able to arm the controller.

Is there a possible workaround for this? Or, are the digital trims even an issue? It seems odd that, in this day and age, someone would release a speed controller that was incompatible with a computerized radio.

I should point out that the motor does beep when I connect the battery, so I do know that power is getting to it. I've also tried plugging in servos on other channels to ensure that the receiver is working.

Any help anyone could offer would be greatly appreciated.

I think you only have to move the throttle, not the trims. Try it and see. I think you'll find that it will program with just the throttle moving up and down.

Try setting the bottom endpoint to 125% or more if needed. Good luck.

Thanks, I'll give it a try.

Something I forgot to mention, there's a red LED flashing on and off on the speed controller. What does that mean?

if it does not arm, you will need to either change atv/epa so that it will hit zero on low throttle

If you have a throttle cut button on your Tx, (you probably do) you could use that.

Got it working. Thanks everyone for the suggestions offered.

Turns out there's a typo in the manual. Instead of middle position, you need to move the stick all the way to full and then back down again.

The build is still going well. I am in the process of constructing the canopy and, after that, just have to mount the electronics and do a final check. Wish me luck!
