Default Powered tip up canopy
Just a stray thought on a snowy day.

How would one modify the tip up canopy to make it powered, with the goal of making it less subjectible to wind damage when open, and to eliminate the rope used to close it ?

Regards,
Mike Stephenson

My first thought is weight and point for failure.
Rope? Been flying mine for 14 years, I don't got no stinkin' rope.

Lubbock is rope country. Ropesville, TX is just down the road a little.

Sorry for off topic: I agree with Mel: keep it light & simple.

Default Light and Simple
I agree, light and simple is best. Still worth talking about.

How do you close the canopy when you are sitting down without a rope.

You got Ropesville right. Exactly 2 miles north (to the foot) of Ropes, I just finished building a lighted 3000 foot buffalo grass runway.

I just reach up, catch the side rail, release the hold-up rod, and lower the canopy.

Default Tip up
Hi All
Will the flap actuator develop enough power to push a canopy open?

Do you plan to put one on each side? One in the middle? I don't think you want to push just one side up.

Default yes you can
We have a acro-pilot at our airport (Goodyear AZ) and he designed and built his own acrobatic single seat and it's incredible.
He doesn't have electric start but he has a electric opening tilt up canopy.
He used something that moves electric seats in a GM car. It works really well and would be make jumping out much easier. I would have electric start first

How about an electrohydraulic system? hydraulic fluid pushed by electric motor. I don't think that would weigh terribly much. You should be able to find a fairly small light hydraulic strut. Similar to this maybe?
