John,
My friend Phil Smith did a bullet-proof setup on his CARF Jug. Ping him at: [email protected] and I'm sure he'll help you out. He used two jackscrew-style electric actuators.

RE: Comp ARF P-47 Sliding Canopy
Aw man, you had to bring that up. Actually its working fine now. I replaced the aileron servos with high-end digitals and the glitching went away, the flaps were always digital and never glitched (trend here). Then the glitching migrated into the elevator servos and rudder servo (analog). I replaced these with just a lower grade digital and the glitching stopped there too. THEN the PowerBox electronic ignition cutoff started cycling off and of course shutting the engine down. So I bypassed the electronic on/off switch, hard-switched the ignition and have been flying the plane since with no problem. I thought whatever is causing this is something that developed over time, something wearing, everything eliminated from consideration EXCEPT the extemely loose and rattling Robart tailwheel retract mechanism! So I did a rebuild on the retract mechanism, tightened it all up and as a joke plugged the PowerBox ignition switch back in. During the ground run it worked fine until I did a range test and at about 50 feet the electronic switch cycled off. I didn't have the foresight to see if the rest of the radio was still working but that was enough for me. I took the PowerBox back out of the loop and flew the plane 6 times with no issues. I think the retract mechanism tightening helped, it could be that the range test brought about the switch cycling...I don't know. But I do know that it works in its current configuration so I'm leaving it alone. By-the-way, I think the PowerBox stuff is top notch and will certainly use the electronic switch in another application like maybe my Robart P-47 with the Evo 80 (though I think the PowerBox may let too much voltage through for the Evo ignition).
Long story but you asked, and thanks for your help via Ozie.

Posted photos, will post parts and canopy slider rails if anyone is still in need of this info... Sorry for the delay John, in the middle of a move right now...

John , I am sure you know this but they have differant lengths of Linear actualtors and speeds !

RE: Comp ARF P-47 Sliding Canopy
JustJets, Which actuator did you select and what voltage did you power it with, 4.8, 6, ot higher?
LDM, cool video. What voltage of power for yours? That is exactly what I want. Way cool that pilot scans the horizon as well. I assume hooked to rudder?
I'd like to use same on my GS Vailly Hurricane.
Thanks in advance , mike

RE: Comp ARF P-47 Sliding Canopy
Thanks guys, I have the 6 volt , 100mm unit .one servo.
I made a push rod that looks like a Y but as the top of the Y extends it get straighter .
Each end of the Y attaches to inside bottom of the canopy and simple pulls and pushes the canopy .
the steps I took were
1)cut rails on a drill press with a cutting wheel
2)made the canopy slide manually
3)added the linear servo with Y rod , its cheaper then going to two !!

Forgot to add , the pilot was an 8oz blue box pilot , his body was removed and rebuild from blue foam , servo was added in the chest area (mini servo).
Added the head , hands , feet , total weight 3.9oz , big savings and better pilot

No problem glad to help .FYI , as you problably know you can make a linear servo from servo city conversions , cheap but you dont get much linear movement , some guys also make "arm type movements " again cheap options .
On this EPO P40 I did not have the room in the fuse to play with a winch type set up , so the linear servo makes it all easy

RE: Comp ARF P-47 Sliding Canopy
THanks Pete !! Yes they are very smooth and very easy to set up vs air !!
I used air on my FW190 an it was very rough .
My ultimate goal is to get the pilots arm to move the canopy wheel but I did not know how to make the wheel turn in a gearing fashion
