EP Thottle Jams Full-on

Anybody experience this problem? Ran through pre-flight check on my Potensky Eagle

with PJS550R 3D 550R External Rotor Brushless Motor, JESA30 Jeti Advance 30 Amp Brushless Controller and Hitec Eclipse radio. All checked out fine including throttle-up and down.



Throttled up and started flying around but found throttle was stuck full on. Moved throttle stick back, forward, trim back all the way, wiggled the rudder, but nothing made a dif. All other controls worked fine. Did a bunch of tricks with grin on face until finally Lithium battery started losing voltage and then the speed controller cut to low power and I landed. Recharged battery and now everything works perfect again. Very weird. Anybody else experience this with a Jeti controller?

I've no experience with that specific controller, but many ESCs are `calibrated' when you first turn on by having the throttle `off' when you turn it on, then go full throttle, then zero again and THEN it's armed (and often beeps.) If something went wrong here, perhaps it was calibrated in some strange way, like with 5% or more throttle being full throttle, and then you hit some trim tabs to keep it above 5% even at the bottom?

Just a thought. This sort of thing shouldn't happen, especially with the newer ESCs, but I wouldn't say it's impossible. I suppose Renault doesn't make ESCs which are sold by Jeti, do they? :) (ok, bad joke, I know.)

Hehe... once a friend told me that the word "Renault" was French for "walk".
