Nir has a prop nut for the P47

Also I spoke with Darryl at Sierra. He is still planning to make gear for the P47. We just need to be a little more patient.
thanks.

For those that are using the UMS-150, are you routing the CH ignition wires through the firewall hole or did you get another hole on the top deck of the firewall?

I made another hole on top. The cutouts on the cowl ring make a good place to secure wires to keep them off the exhaust ring.

Got mine from Tru Turn before they shut down. Could try Ali express and Bangood..I haven't looked for that myself however.

thanks for the info. I checked but didn't see one there. I did see one on https://www.bigplanes.nl/contents/en-uk/p1340.html but will have to verify the size. Thanks for the effort!

I've bought from them before. Good guys. Expensive to ship being in europe but good stuff. Hope it fits

Took some time to get the ground handling straightened out, but she's flying good these days. A short video of the P-47 filmed by a friend a few weeks ago.

What did you do to improve ground handling? Seems to be a challenge with these warbirds.

[QUOTE=jimkron;12782314]My Top Flite P-47 never had a ground looping issue, so I was surprised when this one did. Not sure if the slight angle of the gear (in at the bottom) affects it either, but I couldn't seem to keep up with the direction changes by way of the rudder and I was always behind it on the landing roll out. The only thing that helped consistently was a Demon Cortex Pro gyro. On approach I switch to the bank 2 setting which I have set to normal gain on elevator and ailerons, but 100% on the rudder and tailwheel.

Even though this model is stable enough at low speed that you can almost 3 point the landings, I seem to have slightly more control when she lands with a little speed on the mains and with more air over the rudder, although the gyro seemed to be the only way to consistently eliminate the ground looping issue. Hope that helps.

From my experience, having too much toe-in on the mains can induce ground loop, if there is play on the landing gear (wheel being on the inside) will induce even more toe-in.

Finally did the maiden of the Thunderbolt.
TopRc P-47 with Stingr gear reduction
48 lbs flying weight with batteries
(4) 8100mah lipos provides power
Tribunus 300 amp ESC
26 x 14 x 4 Biela prop
7-8 minute flight times
105mph top speed

Also, spent a lot of time balancing the plane with a Xicoy "balancing pucks". This thing is very accurate, easy to set up, and great with large heavy planes. (no more hanging from rafters)
Despite the 4 big lipos, I had to add 1.5 pounds to the very front of cowl.
As stated already, 159mm from leading edge is neutral.
Our CG test in the air confirmed neutral. Might add a couple more ounces to get the plane slightly nose heavy.

+1 on the Xicoy scales, especially for large planes, they work great. Nice weathering on that one. That's a whole lot of batteries!

anyone know if there has been progress on the retracts? I checked his website and still no listing for Top Rc P47 gear. Lastly has anyone tried fitting a GP 123?

What sort of max RPM are you turning in the electric set up?

John8861

My Feedback: (2)

Still no Sierra gear from Darryl. He did tell me a few weeks ago that he does still have those in his “Que” and will try to get to them this fall.
I think what would help is if anyone here wants a set you give him a call and let him know you are interested in buying a set.

jimkron

Here are the basics based on data collected from the Tribunus ESC:
RPM: 5012 max
Amp draw: 198 max
Flight Time: 8 minutes
Batteries: Not even warm

The Stingr 3:1 Gear Reduction system has been a joy. Bolt has plenty of power. Easy to set-up. Truly plug n' fly.

Nice!

Had to change radio gear recently and ended up using the FrSky Tandem system on the P-47. Needed to go with a dual frequency system after several pretty good signal holds on flights at our field. Re-maidened the plane yesterday and it went great. Did Sierra ever start making gear for this one?

John8861

My Feedback: (2)

No Gear from Sierra. I succumbed and purchased the gear from TopRC. Hopefully I will have good luck with this gear. Sorry for raising hopes.

Colt4570

Sorry to hear that. I know Robart started offer some a while back as well.
