Most ESC's that use stick programming enter Programming Mode if you power on the transmitter first, move the stick to FULL throttle, then power on the Receiver/ESC.  Don't know what kind of beeps or sounds it will make from there.  (You need a motor hooked up to the ESC to hear any programming beeps).

Hello,
I have confirmed that EFLA325A cannot be programmed and I bought another ESC that supposed to be good to 30 Amps.
This one was seriously overheating in 24-27.7 A range after 1.5-2 minutes and was shutting down the motor.

I have returned it and bought another one, also 30 Amps.

This one, Sky Surfer 30A ESC Hobbywing ( www.sonicmodell.com) is programmable and is getting barely warm after five minutes run on the ground.

I am running Cobra 2808/22 (Kv=1330) with 9x6 APC E prop. turning CCW on 3S 2200mAh 30C Battery with this ESC and KR governor.
The model is made of paper-foam-paper sandwich, weights 25.5 oz RTF and is rather small but flies surprisingly well on 50' 0.012 lines.

Please see the attachment showing today's ground tests using eLogger and the RPM sensor.

The data from flight tests will follow.
Thanks,
M

Tim,

You'd be surprised how well it actually flies.  We'll have to get a video of Matt flying to post up.  It started out as a 'Flight Test' foamy RC kit.  Matt made a few modifications to make it suitable for control line.  He intended it to be an experimental test bed for learning about the electric powered stuff but it also turned out as a great stunt trainer to boot.

Matt,

I'm interested to see how much the current drops in flight.  The 1300 mAh 20C batteries are running close to their 'C' limit (1.3 x 20 = 26A).  I guess that's why the 2200 mAh batteries perform better.
