jet builder, mate those robarts look quite good to me. The only weak link is in the cam which is a reinforced plastic thingy and have been known to break on heavy landings. Now this is a good thing in my view as it means it is taking a lot of that force from the heavy landing and disapating it through the breakage.

you can buy an aluminium milled cam from sierras but if you have a heavy landing where does that extra stresses get transferred to? Right through your wing spars and ribs - hence you could get major structural damage as a result.

I like the robarts myself, they are readily available and parts are easy to get. Yes the 622s for the P47 will do the job. Yes there are better ones out there at twice the prices and with slow service.

cheers

oh yeah progress

front subspar is now in and the epoxy is curing. Will sand the ribs even later on and then it will be sheeted. Have already made up the wing skins.

from thee it is on to modifying the mounts for the retracts. Once that task is completed i will make up the dihedral braces (3) and test fit.

Getting close to being a complete wing! Ripper!

more progress tonight. Have now sheeted the top of the LHS wing.

Will flip it over over the weekend and start on the retract mounts.

Hey Peter, thanks for the Aussie lingo lesson. Well we just dodged our first hurricane of the season. It steamed right on by and up the gulf. Looks like it will hit the Redneck Riviera up in the panhandle of Fla. Hope the flyboys up at Pensacola have all their airplanes tied down. It is raining and blowing around here so no trips to our flying field for a few days. So I finished the right wing structure and sheeted it. Tomorrow I will get to see how the retract set up will fit.

In a week I'm heading up north to the USAF Museum at Wright-Patterson AFB in Dayton Ohio. It's a little side trip while I'm visiting family in Michigan. I see on their web site that they have a P-47 Razorback and a Bubble there. I'll be taking a bunch of pictures so if you need any shots of anything let me know. I love that place. I think the AF has one of everything they ever put in service, even the remaining Valkerie. Takes two days to take the whole place in. Later. DWR.

Gday DWR,
mate glad the storm blew on by. We have dreadful wings here today, not on that magnitude but 30 -40 knts which is most unpleasant and hence no flying today. So a Sunday watching DVDs, just got throughthat epic Aviator about Howard Hughes, quite a disturbing movie.

That museum sounds great. would love to see some of the ones you guys have, we are very limited here []. The only P47 shots I need are the camo scheme for Col Schillings P47 "Hairless Joe" as that is what mine will be. Have not been able to find a layout that show the pattern properly.

Apart from that I have a stack of ref books plus about 200 odds digital pics I took at Duxford early in the year of the 2 P47s they have there. Thank you for the kind offer.

Oh just thought. I do need some good coclpit coaming shots that show the sides of the cockpit edging up and under the windshield on the bubble top version. Some good ones of the gunsight would be handy too if you can mange it.

Let me know if you need any too as I have stacks of shots.

cheers
Peter

Hey Peter, i'll get all the pics I can on the canopy detail. I finished the right top wing skin and the gear install. They fit with just a frog hair width of strut above where the bottom skin will be but no big deal. I started thinking about bomb drop set up and came up with simple idea mounting a small servo in thr lightening hole at rib 7A and using some flexible control cable.
Will laminate the hard point to bury the cable, then drill the bottom skin next to 7A. Have to make an access panel to service the servo. Whadaya think? DWR.

Peter_OZ

My Feedback: (1)

DWR,
mate if you could get that servo to lay say flat on the bottom sheeting with the arm travel more or less in a line with the wing chord then it would be ok. You just need to esure you have not too much of a curve in the cable so you do not get binding and cause exessive current drain on the battery pack or worse cause a servo to stall.

thinking about it the hard point pylon extends all the way back towards the flap so if you have the flap at the back end maybe then the arc of the servo arm could actually move inside the pylon and give you almost a straight pull.

have re attatached you pic to show what I mean. You could then use a piece of 2-56 threaded rod. No binding to worry about then.

cheers
Peter

Hey Peter, thanks for the input. I would like to keep the weight forward of the CG so I may try to rotate the servo 90 degrees for clearance and move it to the forward end of the rib lightening hole. That will decrease the radius of the control rod. I found some really slick carbon fiber impregnated rods by Sullivan that I used on my Bronco to go from the boom wing saddle area clear up to the elevators and they work great. I'll let you know how it all works when I get to that point. Later. DWR.

Peter_OZ

My Feedback: (1)

ok mate, you could try those little hitec micro servos, they weigh about 2/5th of a bees dick so light and and reasonable torque

your not far off the CG point anyway so effect on that would not be great

cheers

Peter, I actually did pick up some Hitec HS-81's the other day. They weigh .58 oz. and produce 36 oz. torque at 4.8 volts. I have used these in the past, actually for aileron servoes
in an SE5 biplane that weighed about 5.5 lbs, and never had a bit of trouble with them. DWR.

hey pete p-47 coming well. Wing all sheeted ailerons done flaps almost done. I had to put my throttle servo on the firewall for a nice smooth range. I checked with Jeff Quesenberry the rcu warbird expert he said as long as I am not running electronic ignition im ok. I use a spring starter and the onboard mags.
Rotating landing light mechanism finished works great, now to install the mini mag lite and the microswitch and two AA batts for power. im not running off Rx batt.

great Tim,
how did u get on with that wing warp? All fixed?

I'd like to see some piccies of the landling light setup if you can manage it.

I just ordered the cowl chin divider, pylons and bombs and aflying Ham std spinner for mine from Aerotech models. Plus some goodies for my P51

cheers

wet the wing and added ammonia hydroxide (NH4OH) it was fine. i used the lens from a minimag and added an arm made out of ply with a ball link on the end. epoxied the arm to the back of the lens. a servo slaved with flaps rotates it up and down great. The only worry is my throttle servo up in the firewall. It works great but if I get interference i will spend the 80.00 for an optical isolator for all the servos. Jeff says Ill be fine and he builds giant (huge) corsairs and other warbirds)

kewl, I'd be more worried about heat with that little servo myself

ok have just pulled the other half wing panel off the board, reinforced a few glue joints here and there and will soon begin cutting through the main spar to create the new wheel well in it's scale location.

Couple of pics. you can see clearly the new fwd and aft subspars.
