bigstew60,
I didn't make the bomb drops functional. I had enough going on. I am thinking of doing another and then taking it another level. This plane flies soooo good. It is very nice to have in the hanger.

Hi All,
I am at work and eating lunch and came across this thread and joined. I am also building the big bird and have kit bashed it as much as possible. I will the DLE55RA with the exhaust going out thru the fuse at the wastegate exit. All internal rotary drive for the flying surfaces, working turbo cooler doors, functional scale landing light, inner and outer doors with upper gear door slaved to the strut, added on the tail wheel doors and a full 3d cockpit with a scale warbirds pilot with the turning head option. it is being flite metal covered now and has the black/white checkerboard cowl with operating cowl flaps. I have pictures and video but at this point have no clue on how to post them. I will follow your builds and check in around noon thru the week. maybe get to know some new guys and share interests.

Posting pics and videos is easy. Just go to the "go advanced" at the post or cancle tabs at the bottom, right next to the tabe you hit to post. Then scroll down to " manage attachments" click that and the down load screen will come next. I think you can take it from there.
Please post pics of your jug, we want to see it.

I am attempting to load some pics from my phone. I'm showing how far the flaps open and the plate that's on each side that will have the exhaust pipes exit thru and I'll attach with #1 flat head sheet metal screws. The white paint inside the fuse is from Bob Violet jets and he uses this to protect structure from turbine heat. Its cheap and I have put 3 coats on a cardboard box and it stood up to my propane torch. Backside of the box only got warm after 30 seconds so I figure my plane won't turn into a fireball. I sure will do some testing before its maiden.

just a couple more. I built this with all airlines an electrics run thru the airframe. All is serviceable. I have behind the tailwheel a removable cover where switches and air valve/gage are. Nothing seen from the outside and also the rudder servo with rotary drive coupler. There will be no external horns to flying surfaces. Only the elevator was a bit to workout. I have a bellcrank assembly and pushrod from the servo tray. I laid out all mechanics on onion skin paper laid over the plans. The landing light housing started life as a water bottle cap mounted to a stick held in a vice and coated with Johnson's paste wax. Then I laid up some layers of 1 ounce cloth with polyester resin. Didn't use epoxy for this as its flexible. Then I molded in the lever arm with wire built in. The Navy. Lights are compliments of Luminex company and when I asked if they had anything I could work with the lady said an engineer thought its cool and they sent me several sets with resistors soldered on to work with 6 volts. Very gracious of them. Goes to show just about any guy likes an airplane. Especially heavy metal. If anyone needs accurate sheet metal panel drawings I have some awesome drawings from various razorback models I can send pdf's of.

Been away for awhile. I am building one as well. I am using the EME-60 with onboard starter. Hitec 5645MG servos. Currently mine is in the glassing stage and I am waiting on the weather to get back into the 70's so I can finish fiberglassing.

Finishing resin needs at least 65 degrees for sure but will cure at 55 in a day. I used 2 layers of 3/4 ounce cloth applied at the same time. I filled the weave after sanding with Dupont medium build polyurethane auto primer. It sands and feathers beautiful. If you use flite metal 2 layers of cloth is needed for sure. Don't rush. Be methodical and the results are well worth it. Use a credit card to work the resin and don't go less than 220 grit on the sanding. Believe me it'll save a lot of work. I bought a small electric sander and it worked great for my on 90%,of the airframe. Its shaped like an iron so the tip goes into corners well. If your looking to block it out nicely 2 coats of primer sanding between coats. Don't let weight worry you as most is sanded off anyway. Gotta go.

both of these plans look fantastic, what I would like to know from Tim is what was the weight, engine and prop size. Could you guess at a speed and did it pull with authority. GIVdriver what was the weight and prop size? my plane will be a bit heavy no doubt, I am using the DLE55ra that I have widened the exhaust port and raised compression. I have guessed at the performance for almost 2 years now and just would like to know what others have had. Thanks, Chris

I've seen the ARF version fly ok with DA 50.
I had mine with DA 85, which required quite a bit of cowl hacking to fit. Flew great with good power, but not overwhelming because it has a bulky fuselage with lots of drag. Mine probably hit 95-100mph coming out of a dive. Not clean lines like a mustang to fly that fast. Make sure you use good old Hitec 645 on the tail feathers. I used 90-100 oz servos on elevators that bailed out after a few flights. But I fly my warbirds hard coming out of full speed dives.

I thought maybe 30 pounds would be as heavy as they go. the engine maybe was a little heavier. I hope mine doesn't go that much with all 14 servo's I have and the extra goodies.

Most come in between 27 and 32, mine must have been the heaviest TFGS P-47 to successfully fly for 10 flights, no engine......no fly!
You should be good even at 32lb with a 50-60cc

Mine weights about 31lbs has a G-62 in it with a Biela 20x10 4 blade prop. It is glassed and painted. I used Hitec 645 MG servos. It flies great, top speed approx. 90-100mph out of a dive. It has plenty of power. The wing tanks create a lot of drag. cruise speed around 75-80.

Tim, could you please tell me what rpm your engine runs on the ground and also the power it is supposed to produce. If I could I will look up the specs of the bore and stroke and try to make some educated guess's as to what I expect from my engine after the work I am doing to it. with the cost of the props I really don't want to have a lot of wall hangers.
