Help picking gear for Pica FW 190

I have a Pica FW 190 on my building board and I'm at the point in the wing build where I need to install the retracts. I've never bought retracts before so my knowledge is thin. I know I want mechanical or electric retracts and not air. The plane should have 74 degree gear in order to look right. The plane comes in at around 9-10 lbs in looking at other builders final weight. The wingspan is 63.5" (1/5 scale?). The struts on the plan are about 6" long. The total space allowed in the wing for the retracts is 11.5".

The plans don't mention any specs for what retracts to use. I'd like a more scale set so I'm leaning away from wire struts. What I want to know is the model number for a set of retracts that will work with this plane. Anyone know?

I'd go with Sierra Precision or Robart.

Shinden Machine makes retracts w/struts with the correct angle for the FW-190

http://shindinmachine.com/FW190/FW190.html

Looks like you'll have to contact them for a price.


Spring Air also makes a 74* set that is bored for a strut and is very reasonably priced, part #709

http://retracts.com/Retrax_700.htm

...and you could get just the struts from Shindin.


I have the 65" Platt -D9 and will probably be using the Shindin units when I rework the wing for retracts.

At 63.5" WS, the scale would be about 1/6.66, call it 1/7.

Which Sierra or Robart? That's my problem. I can't tell which gear from either of them would be best for my application.

BTW, I'm avoiding Air systems for two reasons. First, it's the system that's the most prone to failure with all the places in the system that could fail. And secondly, mine is an electric conversion and I want the space for my batteries where the air cartridge would go.

You are looking for retracts for an out of production model designed when air systems were prevalent. In my opinion, they are still your best option.

Any leaks are usually the product of the model builder, not the manufacturer. Mine have proven to be trouble free.

These model tend to build tail heavy, so your batteries will most likey need to be placed in the fuel tank compartment.

With that being said, if you do decide to go with an air system, look for one that fits the more current, although also out of production, Top Flite 190 D. They were of similar size, so the retracts should be easily adapted to the Pica airframe.

Shindin will sell his retacts minus the air cylinders for those wanting to do an electric conversion.

I managed to find my way back to the Lado retracts website. Last time I was there, there was a backlog of orders and not much for me. This time they seem to be up to date on orders. And I found some retracts that will fit perfectly all for $382 shipped. I got electric RS333 retracts at 74 degrees and the exact length struts I wanted. Plus I got some scale wheels and gear door brackets. Hopefully, I won't wait forever to get them.
