Blinking 3 in 1

[DavZee]

Hello, I just replaced the 3 in 1 on my BCPP. Now when I connect the battery with the transmitter already on I get blinking red and green lights. I've checked all the usual stuff like throttle hold switch and making sure the throttle stick is down and trim down. The servos all move when I move the sticks but there is no motor control to the main or tail. Any ideas on whats going on?
Thanks.

I'd check to make sure the connections betaween the 3 in 1 & the receiver are good. Sounds like it itsn't seeing the transmitter.

Or reseat your crystals.

the weird thing is the 3 in 1 is blinking and I have control of all the servo's but no throttle. Thats the only function thats not working. The main and tail motor don't spin up.

That means, rx is seeing the tx. Disconnect your motors and servos and see if it arms. If it does, reconnect one by one until problem comes back.

My CX2 did the same thing excep I had no servos either. The light would come on red and then start flashing red-green. My issue was a faulty bettery. I think the red-green flash means a low voltage threshold has been exceeded.
