[QUOTE=John8861;12761376]I just spoke to Darryl. The Ziroli gear won’t work unfortunately. When I get my model hopefully next month I will call him and then work out the details regarding sending him my wing. Stay tuned.[/QUOTE
That would be good news for many of us. Hopefully he will make the gear a drop in.

My Feedback: (8)

Receiving my RC P-47 tomorrow and wondering what size control arms did everyone use on the control surfaces, 1.25? For those that used the UMS-150, are you using an external pump?
Many years ago, I had the CARF P-47 and I painted it in the Snafu scheme with a Moki 250 (sold it) It was nice to see the scheme again in a smaller version and I don't have to paint it!
Thanks,
Tim

Better to use a longer control arm ( does not have to be that much larger) Check out Nir's build, Nirlybuilt.com. to get an idea of the size. You will need a fuel pump with the UMS 150. To clear the cowl, you may want to set the engine back a bit to get more clearance and use a prop shaft extension. Darrell can make one for you if you send him the length of extension you need

Going electric with mine on a Stingr system with a 4-bladed prop. The system can take some fairly large diameter props.
I'm trying to figure out how to prevent prop strikes. Can anyone suggest the maximum diameter for a prop on this plane?
I see some 25 x 14 being flown. Could you go 28" as an example?
Thanks,
jim

Thanks Jason!
Just want to reiterate to everyone, (Please check the 8 wing tube mount screws in your P-47's). I was able to remove everyone of these screws with finger pressure and the "long end" of an allen wrench. Even if you don't use longer screws with washers and nylocs, at least tighten them with some Loctite. I don't want to see anyone have an issue in the air.

This is the fix on the front set of screws.

If I can make a suggestion ref the pull pull cables on the tailwheel. I originally used the included wires (doubled up) and had a tailwheel wire failure at a warbird show recently, (no other damage). I would say to use stronger Sullivan style cables to avoid this. Going to make an upper deck over the rudder servo for a separate tailwheel servo, because I want to be able to trim them separately. Also adding my first ever gyro to an airplane, because of the ground loops on landing on asphalt. The electron retracts have held up famously, but the ground loops during roll out on landing are getting ridiculous. Never thought I would use a gyro, lol.

A couple pics of the latest updates to the P-47. Made a bridge over the rudder servo for a separate tailwheel servo as mentioned earlier. Went with ball links on the tailwheel control arms instead of tying the wire through the hole in the aluminum. Not sure if anyone else had a tailwheel retract alignment issue, but when extended, mine was about 3/4" off to the left because of how the former was misaligned. I remounted the whole assembly and got it straightened out. Also finished installing a Cortex Pro, my first real gyro. We'll see how she handles on the ground now.
