Title: Retracts
Post by: Zene Gillette on January 16, 2018, 03:55:24 AM

Hi ... Can I get parts and circuit for operating servo retracts on CL airplane. It will be a pushbutton activated by bellcrank. Push-on only and relay should work. Not RC controlled.  Hope enough info. Thanks, Zene

Good Morning Zene;

  Bob Hunt fitted out his "Second Wind" e-powered twin with retracts.  That build diary is in the "Gettin all AMP'ed up!" section.  You can read about some of the hardware used in this specific post: https://stunthanger.com/smf/gettin-all-amp'ed-up!/new-electric-twin-project-back-on-track/msg204800/#msg204800

Zene,

I have NIB retracts that are for servo activation. If your interested PM or email me. I should have the 180 degree servo, also NIB which is used for this purpose.

Simple setup.

I have a new set of self-contained electric retracts  that I will list in CLASSIFIEDS in a day or so. (no servos or pushrod linkage needed).  If you need some, give it a look.

Sorry guys for late reply. I'm not looking for retracts, just the circuitry to operate servos or servoless retracks using just one push-on switch as I mentioned. Zene

If the actuator button is activated by the bellcrank, I assume it would get pressed at either full up or full down.
If you fly like I do, full up and full down are accessed at least a few times every flight.
Logically it would follow that the retracts would be going up and down several times during the flight.

Jim ... Thx, I didn't think (as usual) about two switches. I will be using a Brodak FM-eTC (one switch at each end) slider throttle and should be able to put in a few seconds delay on the off throttle button. As it will be a park flyer I should get by without 100% throttle except for takeoff to retract. Will have to re-think; might be backwards. Zene
