To misquote a friend, "Nothing exceeds like excess"

He said that when I hung a .32ABC on the nose of my first HOB .19 sized P-51. It went like scat.

Somewhere there are photos of me flying off the wing of BB Weber and his B-17. Fun times.

Default Topflite new P-51 build

So, with the generation of builders getting older and the availability of balsa kits dwindling, I decided that I wanted to do a nice build with a TopFlight 1/5 Scale Mustang P-51D while I can still get one. I'd really like to do it right, I found some resources on exhaust manifolds, sliding canopy and there are manufactures for landing gear (seems Sierra is best) though I like the scale of electric gear speed and the door sequencers, not sure the same can be achieved with air. Lines eventually leak but I have heard lots of mixed reviews on Robarts electric retracts. That being said the sliding canopy and gear doors seems to be the least amount of available knowledge on how that has been done. I see Hangar 9 has a 1/5 scale ARF. Any chance those parts MIGHT work with the TF 1/5 scale? Specifically the gear doors and the rails for the canopy slide....or the entire canopy itself, which looks quite nice.

Thanks

There is little that is inter-changeable between the TF and H9 Mustangs. Retraction speed for full scale Mustangs is about 3 seconds for the wheels to hit the wells, a little longer for the doors to close. I used battery voltages from 4.8 to 10 volts to operate the Robart electrics, the actual cycle speed is between 9.5 to 10 seconds, air is much faster and you don't have a hung gear draining the receiver battery. I use 8-32 machine screw nuts to retain the air lines on the nipples. Tie the air lines down and insulate them with spiral split fuel line to keep the lines from rubbing hard parts inside the plane. For long runs I use spark plug cable insulation from auto parts stores. Tie wrap everything down and you won't have leaks. H9 recommends using servos to drive the gear doors, if you do that provide separate battery power. Prop blast will force the doors to open partially in flight, a servo under this much strain pulls 5 amps, it will fail quickly. Driving the gear doors from the door's trailing edge like the instructions say is asking them to blow them off in flight. I use Robart air cylinders to drive mine at the door's leading edge, just like full scale Mustangs do.

Thanks! Your planes look amazing. So did you just build all your retract doors? Do you have servo driven canopy? What did you use for your aluminum covering? Would you recommend electric or air retracts?

Much harder to do on the .60 size one. Still under construction, but have a working setup at least.

I cut air-ply panels to fit the holes, when I have it all working correctly I glue balsa sheet to the panels, then sand to the airfoil. When ready for glass application I use Saran wrap to cover the openings, re-install the panels and apply the glass and resin. After the resin cures a hot knife following the panel outlines cuts them free, also chasing the screw holes. The brushed aluminum is available direct from Hanger 9. You can use the brushed aluminum along with chrome to give the different grain and polished effect. I used a picture of the actual plane for ideas. Some of the engine panels can only be simulated by using actual metal duct tape, it looks like the stainless panels the real plane has covering the area around the engine exhaust, and a sharpened brass tube press into the metal tape gives the illusion of the dzus fasteners securing the panels to the airframe, A small screw driver pressed into the circles simulates the dzus fastener's screw driver slots.

I tried air AND electric on several planes, the electrics with their slow cycle speed worked best on the TF p-47 razorback, the electric's slow cycle speed interfered with the main wheel doors that the P-51 has. I did get them to work after a lot of fiddling around, on the work bench, at least, under prop-blast conditions it all had to be reworked. I ended up yanking the electrics to replace them with air powered gear, much easier to get the right timing using a Jomar gear door cycle controller. (I haven't been able to find the Jomar to be available anymore) I tried door sequencers by several different sources, the ones from H K were dead on arrival, one from another supplier would continuously open and close the doors, and never worked at all to operate the main gear. The answer seems to be to buy the expensive sequencers that the JET guys use. I have been using the one Jomar sequencer for 15 years and 4 or 5 models.

My brother has the E-flite electric gear in his H 9 Mustang, they work well on the bench, but he hasn't flown it yet. I read numerous reports that complain about the E-flite gear jamming in the air. The only solution seems to be flying the plane very slowly until the gear have completed the cycle, both up and down. They use very tiny electric motors that over-amp under prop-blast conditions. The Robart electrics were better in that respect, but I had a failure of the screw threads pulling out of the worm drive parts, which I fixed by making my own parts from mild steel rod from hardware stores. Making these parts is simple and easy to do, I was in a hurry to fly or I could have gotten new parts from Robart. I reasoned that if the original parts were that bad, I could use better metal and make my own. The plane I did this too, I sold, and is still flying with my parts. It speaks to the poor quality metal used by the manufacturer when MILD steel is better.

The hanger 9 Mustang I sold had Robart air installed and it worked reliably until he had a throttle servo failure and landed in a tree.(about 60 flights). He, or the original buyer changed the air cylinders out and replaced them with servos for the main doors. I noticed the doors hanging open when he flew it. I didn't give him my only Jomar controller so I don't know what he used instead.

What ever you decide to use, have some friends hold the plane off the ground and test the gear for proper operation under take-off power prop BLAST conditions. If they don't work properly, you have work to do. The original D model Mustangs lost wings and killed people when the doors opened at speeds higher than 150 mph. The cause was traced to changes made when they changed from the B model wing to the D. The solution was going back to the B model system, and keeping the hydraulic pump ON.

Dear Mr.Stang, what a beautiful machine you have built! Be certain you did honored Herr Uwe Henn.

Regarding joining here you just have to pickup the first number available, that at this moment is 90. If you do not care I add you, is a pleasure to update the brotherhood list with your name and thus, you may add that to your RC Universe firm.

Again congratulations for that impressive scale effort, Sir.....

Best Regards.

Default P51 kit

Anybody have a Top Flite GS P51 kit your not going build? I am currently flying the ARF version and would like to do a full kit build. The Top Flite is a great flying warbird.

Hello,
I have two kits one an old Fliteglas and one D&B kit both the same except the D&B was altered in the nose to accept a different sized spinner. I need to find a cowl for and have had no luck in finding anyone who still makes these kits or replacement parts. Does anyone have ANY information to where I could find the cowls.
Thanks

Hi Terry,
Check out this link, they show fiberglass cowl for the D&B Mustang: Fiberglass Specialties Inc Catalog

Good luck,

Hello Larry,
Thank you for your reply. Yes I did try them and they do not make any of those parts and do not do custom molding.
Appreciate your help

Does anyone know of a kit or arf between 70 and 80in WS? Would like a B/C model but that probably impossible. I do have the TF B Conversion kit. Bad pic but it does show what can be done with it. That plane is a H9, P51, 77WS. Sadly sold many years ago
The 20CC, H9, P-51 looks ok but thats all covering and once that is stripped off for some arf bashing it seems expensive for the work i would plan on doing to it. Make it a B/C, add balance tabs and such.
Thanks for any suggestions.

I little bigger, than measurements given, but if okay with the size, checkout Vic RC glass fuse? Looks like a really good start, and reportedly a great flying plane

Balsa USA has a 1/6th scale kit with a 75" wingspan. They show the max engine to be a 1.50. Might be just what you are looking for.

Build it according to the plans, add a few small formers on the outside and cover with 1/16th balsa to get the required shape you are looking for. If you want a better scale one, it going to cost more. I don't know how much you are willing to spend.

CKD315,
In the article it said this Mustang won at Oshkosh, What was the actual year, I don't recall judging it and I have been a Warbird Judge at Oshkosh for over 25 years.
Thanks
