Yes the outer nylon part of the push-rods are held in place with epoxy.

Thank you 320pilot. I picked up some crazy-strong rare earth magnets to hold my canopy in place. Couldn't resist playing with them first though...



I'm using two at the front & two at the rear of the canopy. My worries about these not being strong enough were totally unfounded. It takes considerable effort to remove the canopy...



Not something I can really photograph, the rest of my time today was spent programming the radio...



The motor is now controlled by my three position flap switch. It runs at 0%, 30%, 100% power. My throttle stick now operates the flaps with the last 25% feeding in the crow mixing. I may add camber control too but for now this setup should get me flying.

Very little to do now. I still need to add a smidge of weight to the tail, plus I want to makeup some short servo extension cables that I'll plug into the receiver so that when I remove the wing I can unplug stuff from the extension cables, not the receiver. I figure the less the receiver is disturbed the better.

The weather has been terrible this week, raining & windy so I don't feel too bad about these delays, I couldn't have flown anyway. The forecast for the weekend looks promising though.

What is your all up weight? Please and thank you.

Shame about the Texan mate, but good to hear you got the ESC/BEC issue sorted. You'll feel a lot better with that system in place.

On ESC's, I really like the Mystery line of ESC's, also sold by HobbyKing as their 'Blue Series' line from 12A to 40A rated continuous output. Very smooth throttle curves, great response and good programming options (with instructions!) They also tend to have decent switch-mode BEC's as well, the 40A has 4A from memory.

Anyway, just my two cents. Hope the setup and flight goes well!

I'll admit I've been avoiding weighing her. I almost don't what to know as there's little I can do about it at this point. She's certainly not a featherweight, I will say that. After I'm done balancing her tomorrow I'll drop her on the scales & we'll see what's what.

Yes electronics can have all the programmable features in the world but without a programming manual what's the point? I love HobbyKing but sometimes, well umm, yeah. Anyway thanks once again for the advice. I spoke with our LHS RC guru about your 1 amp per servo rule & how you felt 3 amps wasn't going to cut it for a 100" full house e-glider. All I can say is he raised one eyebrow, Spock style & scoffed at the idea. Still I agree its better to air on the side of caution. More amps than I probably need = one less thing to worry about. Thanks again for the help.

I can't be sure but I think your original ESC had a 3A linear BEC. If you're running from a 2s lipo I would be happy running 4 servos but on 3s I'd be concerned even with 3. If you had SBEC, 3A would be fine.
