Looking for some feedback on linear servos!
Hello everyone, I hope everyone had a great new year and to start 2018 out i'm looking to get some feedback on linear servos I will be adding to my product line up. These linear servos are made by Actuonix which was named fergelli before they swapped names. I am trying to get some previous user info and or thoughts on to help narrow things due to the many options in torque/stroke. With that in mind I can order anything to fit your particular need but would as you will see there are ton of options, which is a good thing. The first are the PQ12s these are tiny AA battery size linear servos that have three gearing options from 4-11lbs of torque all with the same 20mm stroke. So I figures since the speed is all really close and fast just ordering the 30:1 @4 lbs and 100:1 @11 lbs is the way to go. The would be great for gear doors and canopy locks, Here is a small video to show the three gear ratios:
The next actuators are the L12s, now these have many more options and will be more for gear doors, sliding/opening canopies, speed brakes, wing sweeps(F-14) and some folks have mentioned using them for flaps. These come in three stroke lengths, 30, 50, and 100mm which isn't a lot but you can pick three different gear ratios with each length. Here I figure doing maybe a 50/50 split since some folks will need torque for those big speed brakes, while others need a fast stroke but not much torque on canopies. The higher torque is slower but if you have a shorter stroke servo then it can be about the same as the longer stroke at a faster ratio. So you can see the L12s can easily be a huge amount to meet needs so getting some info for the first start is will be very helpful. Here is a video of the L12s:
These are PNP and have built loads so if something hangs they shut down
I already have orders for PQ12s 30:1 for canopy locks and L12 50mm 100:1 for canopy open/close and L12s 100:1 100mm for speed brakes to help give u guys an idea of what folks are using. So any thoughts or what you like to use will help I have a Facebook page and currently adding the servos to my website

So let me know your thoughts and thanks up front!

All I would need is the length in mm of your sliding canopy from open to close.

Keith,
I use one of these for the sliding canopy on my scratch-built Panther. Its been in operation since I built the plane 6 or 7 years ago. It an L12 unit and I'm pretty sure its the 100mm 100:1 gear ratio. Its slower, but the real one was slow as well - least a guy's hand or head got smashed!
It works *great* for this application and since it works on a regular PWM signal like a servo, you can adjust the actual throw to the application using your transmitter's ATV just like a servo.
If you've ever seen me fly the Panther, the canopy is slaved to the gear channel, so I take off and land with the canopy open, just as in the full scale. The early jets didn't have an ejection seat, and even the ones that did, it wasn't rated for use at 0 altitude, so they would leave the canopy open during takeoff and landing. That way, if they had an incident like a flame out (not that uncommon back then) and had an off-field landing or ditched, they didn't have to worry about the canopy getting stuck closed and them not being able to get out...

What's the target price point for the small ones? Been eyeing these at places like ServoCity, but the price kind of puts me off for my purposes (this brand doesn't appear to be there, though)
Sure would like to play with a few, and if it's close to reasonable, then I wonder what the feasibility of using them to replace air cylinders on retracts is?

One last note, I try to keep my product advertising to Facebook and my website but I’m putting an order together for the end of the month so if your interested let me know. Cheers
