Excellent. Isn't math cool.

I just came from 'plant 1'. The wings are looking very good. Brian is almost done hinging everything. Just 1/2 of the right wing hinges to glue. The fit is as good as it could be, and looks very scale. Much better than our ARF version. A lot of time was taken fitting these control surfaces to the wing.

Unfortunately, I left my camera in my wife's car, and she went to work tonight at the hospital. I'll get pictures later.

Brian, I checked on the small inboard aileron trim tabs, and they DID work like the ones on the elevator. If the aileron was up, the tab was down, and so forth. They were not adjustable by the pilot. This provided a boost to the control stick. These will have to move in a scale manor. Only the outer tab on the left aileron was adjustable and can be fixed on our model.

I have the gear in my shop for painting, so I thought I'd post some more pictures of the electric conversion.

Gary 2 things, first will you share your design for the tail gear door geometry. Second, what will you use for the door function on the main gear? I think I might have to get the down and locked option as well. $500 for the tri set

ram3500-RCU

My Feedback: (221)

Absolutely. I need to go through the final parts and take some measurements for you. Those numbers, with close up pictures should do it, right? A list of the parts I used may be of use as well.

The main gear doors will be air, the only air on the plane. Just (4) air cylinders, (2) in each bay. The system will be a closed one, as all the components will be in the wing. Only the wires for the sequencer will go to the fuselage. With the electric wing conversion, we have a lot of room in the wing now.

If we were to loose the air, the electric gear will push the doors open, for a normal landing. And the tail is all electric as well, so the chances of needed a belly landing for gear problems are very very slim.

Keep in mind that this conversion cost is partially offset by the air components you will not need to buy.

It would be nice if Sierra made available the gear without the air cylinders as well. This would further reduce the net cost of the conversion.

BTW, on the strut covers on the mains, Brian is not just fastening them to the struts. He is articulating them as per the full scale, and we will have the scale leather cover to bridge the gap at the leading edge.

The business end.

2.5 deg right, and .5 deg up thrust.

I little more telemetry data, compliments of Phil and Greg.

" Phil moved the temperature probe to #1 cylinder and we saw 155-165 degrees F in flight verses the 135-145 F we were seeing on #3 cylinder. I also finally closed the cowl flaps in flight and we saw engine temperature increase by 10 degrees."

Thanks guys.

Exciting. How about those nice custom covers on all the wing and tail parts. I thought that was pretty classy.

Feel free to post in this thread about your experiences with her.

I'll have that information on the gear doors shortly.

I now have some dimensions for those who may want to try this approach to your tail doors. When I have more time, I'll do a drawing and post the PDF file of it. For now, here are some things that will help.

First, the parts. I used

-(4) Dubro 4-40 ball links. (cut 5/16" off each one)
-(2) 1/2" 4-40 all thread
-(2) 7/16" X 2 3/8" X 1/16" brass
-(2) 1" X 1 1/2" G-10 or 1/8" ply (for the horns on the doors)
-(2) 4-40 cap screws 1/2" with lock nuts (these replace the OME bolts for the piston anchor bracket, and are also used for your new link mount)

Now, the control arms. These are adjustable. Mine are as follows, measured center to center on the ball links. The left is 1 5/16", and the right is 1 3/8". You will want a 10 deg. twist in the ball links.

The anchor bracket mounted to the gear is two pieces of brass soldered together to make an angle bracket. (you can also use a 1/2 X 1/2" aluminum angle if you have access to one. Drill two holes for the 4-40 Dubro ball links 1/4" in from each side, or exactly 1 7/8" center to center, and 5/16" up. These you can elongate vertically about 1/8" or so, so you have some adjustment up and down from this 5/16" location. Mine are set at 5/16.

The horn mounted to the door. Again, I'll make a drawing of it and post it later, but the exact location of the ball link attached to the door ( where the ball link attaches, NOT where the center of the ball is) is2 1/8" back from the front of the door, 3/4" up from the surface of the door to the center of the bolt, and 7/16" toward the center and off the hinge side of the door. The arm will do this for you if shaped correctly. Mine is glued to the inside of the door at a 12 deg angle, as you can see in the picture.

The cut out for the tire is important as well. Here is some info on that. First, I cut the doors apart 9 5/16" back from the front. This allows the entire wheel cut-out to be in the front doors (scale). That cut out is 2 1/2" long and runs from 6 9/16" back to 9 1/16" back.

Here are some more close ups. Please ask if I missed anything you need.

One more thing, the location of the hole in the front doors for the tire, is dependent on the bulkhead the gear is mounted to being 3/16" forward of the front of the bay opening. The ARF has this structure glued in, but the kit does not, and your location may vary slightly. You will simply add or subtract from my number, depending on where your bulkhead is located.

The bulkhead on our #1, the ARF version, is 1/8" forward of the opening.

There are other variables like where exactly your hinges are glued in, but I think there is enough adjustment in the design to accommodate these variables. I worked on one side at a time, as you saw in the video. This is much easier.

Have fun.

Another tip on my install on the tail gear is where to have the pull-pull cables come through the bulkhead. This is critical due to the links for doors. The hole for them needs to be next to the plywood mounting plate, and 5/8" down from the bottom of the fuselage. The cable sleeve should be pulled through till it lays on top of the links. This way the metal steering cable is not in contact with the arms. As the gear is retracted, the cables lay over the arms quite nicely. They shorten up about 1/4". Enough slack, but not so much that things get out of whack.

Here you can see the cable and it's sheath, and how it is run over the arm.

this is my other fav warbird and you are doing a fantastic reproduction true to life build and what a engine. I hope you are entering it in some kind of show or contest best of luck with the rest of the build.

Thank you Bruce.

I'm happy to announce, your wish has come true.

She will be entered in the static competition at the 2012 Toledo RC show this spring, and then it is on to the 2012 Top Gun event in Lakeland Fl. the first week in May, where she will compete in the 'unrestricted' class, and be flown by non other than Dino DiGorgio. We are very pleased and proud to have him as her pilot for her first flying competition.

I will fly our Meister P-47 Zombie at Top Gun in another class.

Doing some panting of various components of the gear like the main wheels and gear, air cylinders and such, so I finished the tail hook as well. Distressing and weathering will follow later. I like to do that on the entire air frame at the same time.

ram3500-RCU

My Feedback: (221)

Here is how the tail hook can move without damage as the gear absorbs shock on the ground.
