Hydraulics maybe another option

I know someone has already thought of this but wouldn't it be feasible to loose the hydro power pack (in some cases they are beyond repair if I understand correctly) and go with linear actuators? Such as this, I know this one is 12V and maybe too slow but I just grabbed the 1st one remotely close off of Graingers web site.

The amp draw of three such actuators (maybe 4 if you chose to adjust flaps while gear was cycling) all running at the same time might be a temporarily large draw on one's battery/alternator but given the weight savings, simplicity and "cheapness" it seems to me a decent idea.
In reality unless they are loaded or in a bind they really pull next to nothing amp wise. How much force do the flaps require to extend/retract?
These things are available with weight ratings and stroke lengths that should more than do it, also I know they come in 24V as I have a small one.
Please don't shoot to kill I am just thinking aloud here...
 
The problem would be getting a field approval for an non-aircraft part. If someone was really masochistic, I suppose they could try to pursue an STC. I would almost think you would have a better chance using one of the manual hydraulic systems approved on the Cruisair. Mine pumps up or down in 6 easy strokes. It is really simple! After it taking me 6 months to get my last field approval ( for a PMA'd part!!!) I had to retire my black leathers, chains and whips!

Really? Damn so it's not an engineering problem at all then. I like a lot to do with aviation, regulation is probably not going to fall within this category.
What is required to take a GA plane over to experimental class? I have looked a little but have not found a clear answer.
 
Rock of ages, to get experimental class you will need an experimental plane. If your thinking that you can make that Bellanca Experimental you better contact the EAA and they will tell you. Your in a whole new game when you bought a plane alot of rules suck and alot of rules make sense. Remember this is run by the FAA the Govt. and they have not done a dame thing right in the last 100 yrs. Lynn the crate :lol: :roll:
 
Well given the last "right thing" would have to predate the 1913 passage of the federal reserve act, I would put it at like 97 years...
