For such a monster of a model, did hyds cross your mind at all? Looks like the speed of your actuators is about right, hope they last long time for you.

Sometimes when I make a long post, before I click "post", I highlight entire post & right click & copy... just b/c I've had it happen before with some computer glitch & loose it all ...I know your pain.

There is a 5000 character limit too to consider, so don't try to post an entire book in one post. Take your time, lets have a look at this unique creation you have mastered.

I looked into hyd's vs actuators and earned myself a migraine that lasted a week. I never really got to the bottom of it, I couldn't nail the hyd people down with precise specs about their products so I decided on screw actuators and ESC's. I'm working on new heavy duty ones to replace the ones fitted, all have failed miserably. I already have some parts and motors from China. They will be tubular resembling a hyd ram, but 12V electric. The speed of those 60's is about right as you say, and they have sufficient power.

I personally are not too happy about the possibility of oil leaks and also having high pressure oil in the mix. I like the controllability of the RC actuators - plenty of adjustment available in the RC mixing and the ESC's.

Cheers

My Stahl 742 dozer was more than 13yrs old when I took it apart last fall, never ever had an issue with an oil leak & never needed the pressure to be that high either, just enough to lift the nose off the ground so the blade would dig in. I took it apart b/c some parts of the u/c need rebuilding.

Glad to read of your success. I like the smooth action of electric actuators all the same. Like Scranton, PA and R.G. Letourneau, I'm going all-electric.
