Hi Flyboy, I'm still checking the batteries. I charged them up this weekend, and turned on the tx to see how long it took it's little needle to creep downwards, but then I forgot to watch it -- go figure. I'm thinking I'll rig a little LED circuit with fixed current draw to test the rx battery. I don't have a cycler, but one of my coworker's husband is the VP of the local club, so I'm sure I could borrow a cycler or even get him to check out the batteries for me if I ask real nice . Even if I need new batteries, it's still way cheaper than a new tx. The servos are actually fp-s148 servos, and I was planning to pick up a cheap full-sized servo from the LHS for the throttle when it came time for radio installation. (I think one of the servos got lost in my parents basement, so I only have three). I did fire up the tx and plugged in the rx to test all 4 channels and my 3 servos, and lo and behold, I move the sticks, and the servos move! My plane is still far from built (nearly finished with the left wing half after working on it this weekend) but it was still fun just to play around with the radio.
