favorite retract valve
 

I am wondering what everyone's favorite retract valve is? I would like to find one that has no servo involved and is one unit. Thanks in advance for any ideas or thoughts on the best setup on servo based valves.

BVM Hi Flow value ... . But it requires a servo.. Jet Tronics makes one without requiring a servo . either one I've used and have been satified with the results

hi, I didnt know you could get a 1 piece unit. will have to have a look.
one that does require a separate servo, is the ROBART, unit, they have one that can be speed / flow adjusted, to give scale style looks,
I have a couple of them, not all that impressed, there are not enough threads where the adjuster screws in, it is only in a couple of turns, it is very easy to strip the threads out, quite a bit of playing around to get the speed the way I wish then as the lock nut is tightened it all changes again, as I said, not all that impressed, the design could be improved.
they are a bit of a hassle getting the throw set up correctly for the servo, but seem reliable, I give all my systems a squirt of "Inox" every so often, to keep them lubricated, it will work its way right through the entire system over time.

What is this going in??

RE: favorite retract valve
 

The one listed on the Global Jet Club site consumes 350 Milliamps! Does anyone know if that is constant or just when the switch is flipped?

I currently have a pica FW 190, but I am looking for good solutions to my upcoming warbird projects. The Pica 190 has air up spring down retracts and the other aircraft have air up air down. It just seems it would be best to have a single unit. Of course battery consumption could be an issue, especially in my little 190 as I would not want another battery just to power the unit.

Looks like the brake valves are what is needed for air up/spring down retracts. I am gonna go for it and any issues I run into I will post back here.
