Bearhawk Builder

In the woods
Can't remember what Jean-Marc uses on the Datum skis but they are very strong. They'll pull a 2600 lb Bearhawk up on the ground. Maybe give him a call, you can even speak French!
I forget to mention they're on separate switches, so I can have one tire down to turn around in tight places

This is the actuator I use. Iv had them 2 winter's and many cycles no problem so far. The only problem with the better actuators made here is the weight, they weight is about 3 times of the ones I use.
Bought a pair of Fluidyne 3000 Fli-Lite. I only need to change plastic bottoms and built some brackets so they fit my landing gear axles...
I don't like the idea of running oil lines and pump into the plane..
I've been thinking to run them electric and I would like to cycle them on the ground.
What electric actuators do you use?
Or a 12v mini double acting hydraulic power unit that I could mount outside the airplane?
Any issue or concern ??
Thanks!

What's your concern with hydraulics? All that's inside (usually) is the pump. Most of us put the fluid reservoir on the engine side of the firewall. Very reliable.
I do not like the idea of rooting messy oil lines and installing an hydraulic pump inside the plane, and remove all that when spring season comes.. Maybe there is a way to do a clean and simple setup??
Under water several times sounds like poor judgement to meMy hydraulic skis have been underwater several times. Once I got the airplane back on top they operated perfectly even in sub zero F temps. Electrics would concern me in that situation.

Electric is very tempting, but looks heavy...

Hydraulic is not messy if you do it right. I like the reservoir mounted on the hand pump - less piping and convenient to maintain. The only things to remove in the spring are the skis and pump, but a lot of people leave the pump in. Done it many times. Eazy-peezy.
