Yup, 100% sure... I'm a bit paranoid when it comes to plug in stuff! And - like I said - after adding a voltage regulator, all was well. Oh well, maybe I got two "Monday" controllers in a row.

Just a quick Note:

I purchased a couple of sets of "Common Electronic Retracts" from PW-RC back in September.
I never got around to using one as I had reserved it for a winter build project which I completed earlier this month. Last week I was about to maiden the AC when suddenly one of the retracts became bound on a gear door and despite it's built-in overload protection, it began smoking and burned up.
Remembering that this set had been purchased over 5 months ago, but none the less, when I contacted Philip he generously offered to sell me a new set at cost which was 50% off his retail and ship them free of charge. I've made several purchases in the past from Philip but nothing extraordinary so for him to extend such a generous olive branch a full 90 days after the warranty has expired is uncommonly generous.
I just wanted to let you guys know that although there are many dealers to choose from, there are not many that will give you a good reason to choose them. This dealer however, certainly is one of the rare gems.

They're different. PW-RC has for the common Etract the PZ-15090. FW's are similar, but the housing is a one piece where as the 15090's have 2mm mount holes top and bottom to mount the plate either on top or bottom or directly.
I added the comprehensive list in this thread with pics showing the differences though IMO some of the parts are interchangeable.

Ok, I ordered a set of the Changsun and Freewing gear. I had one of the Changesuns stop working during setup/testing, and 2 of the Freewings stop working in setup/testing. So, I have the 2 working Changesuns as the mains and the one working Freewing as the nose gear. My concern is that the nose gear, which retracts forward for strength reasons, will not have enough torque to retract into the wind. I know it needs to be retracted at a fairly slow speed but I am concerned it will still have a problem. I will have my bec set to between 5.5-6v so hopefully that would help.

So, couple questions...anyone have any suggestions on a replacement motor for this retract that would have more torque? I won't care if it is considerably slower. Also, how does the "over current" protection work in these? Is it actually based on current or is it just a timer? If I do find a higher torque motor, will it cause a problem with that?

Anyone interested can see the retracts in operation in my build log at http://www.rcgroups.com/forums/showt...1378975&page=3

Thanks

T is your gear travel set to +/-150%? I must be just fortunate to have purchased 22 or the CS and PZs and none had issue except for two that I pushed beyond rating.

I have a set on a FW F-35 that swing forward and close the door on a string. No issue. I'm working on another LX F35 with them also.

These all say that they have over current protection and I tend to believe this since it doesn't always cut out at the same time and the more you repeatedly stall them the shorter the cut out.

Trouble with a different motor is it may trip the over current circuit. But ask PZ directly. They can tell you for certain.

They are definitely broken as they were being tested on a Y harness, one works, one doesn't.

Yeah I was going to use a string to close the doors too but was worried about it stalling. BTW what kind of spring setup did you use to have the doors spring open?

After posting this I set my bec to 5.5v and they close much better now. I will check everything radio-wise to make sure all parts are 6v compatible and may give that a try if I see any stall issues.

Thanks

For the FW F35 I added a arm to the strut to hold the door from fowling the sequence. It was only ok. I later tried adding magnets on another model; that is you put a magnet in the fuse and a piece of metal screw head or the like in the door at the edge of the door to meet the magnet. Its just enough to hold the door but not too much to stall the etract.

Mainly though I've used a servo to actuate the doors. I also run most of my stuff at 6V just to help make certain I don't brown out.

For the nose gear on the E-flite 25-46 size tricycle electric retracts, does anyone know if the steering servo mounts right on the retract, or is it some sort of linkage or pull pull arangement for steering?

Jagzilla,

The nose retract has a slider, just like the smaller size. However, the retracts are all aluminum and look to be really heavy duty. I have a set on the work bench, so if you need any more info, just ask.

You could mount a small servo on the side of the retract frame, but in my other installations I opted to mount a more heavy duty servo a short distance away.

Hope I helped

Al

you can go pull-pull or servo for steering...servo steering can be set up a few different ways...i went this route...

Gunracer,

Hey that is a real neat setup you did for the nose retract. It sure beats trying to glue the servo to the side rails or even to glue the servo to a remote location.

Gary, that's great. I like the idea of you stocking Tams strut kits.

I am looking for a set of electric retracts that will support an 8-9lb F-18 that is fiberglass. I saw on the first page of this thread that E-flite makes some but I was wondering if anyone has had experience with others?
