The plane still new and flew just once for test flight.
Do you have a way to cost effectively ship it out of UAE or are you only willing to sell locally ?

My offer is to everyone and internationally. I can ship it as well but I prefer if the buyer can manage and ship it buy him.
If interested you can contact me on my mobile or Whatsapp.

Yes, please take the buying/selling off line, there's a rule regarding classified posts in the discussion forums.

That is good to hear. Hopefully they are getting the manufacturing problems ironed out that many of the earlier kits seemed to have. Let us know how the wings fit together and align as you start to build.

Hey guys just lost my TF p51 today, long story anyways my DLE55 with scale keleo muffler are fine.

Dose anyone think this muffler would work?

Why did you chose the hanger 9 over the Too Flite

The H9 has a full scale cockpit with sliding canopy that can be made to operate with a servo (with some work).
It has full and proper working landing gear doors front and rear. But you need to buy the gear controller.
The engine exhaust ports are more realistic.
There are easy to install bomb/fuel tanks that can be installed on proper ramps that can be made to drop.
Available lights in pre drilled holes.
I particularly like the 3 piece wing so most of the wires are always attached to the center wing section. It would be a pain to connect all the wires and wing to the fuselage in my plane as I have the bombs and lights as well as gear door wires to tend with.

Its nice with the 3 piece wing. Aside from the wiring, its nice to store and transport it sitting on the landing gear rather than needing a cradle and installing the wing panels while it's sitting on the gear is nice as well.

...pin hinges on all control surfaces, scale retracting tail wheel, nice scale detail bits in cockpit, super scale main wheels (not included).

So the new gear is in and I'll give this another go. Fixing the left main that broke off was fairly easy since it broke out clean. I just used epoxy to put the 2 severed pieces of the wood mount back in place. Each piece had 2 of the blind nuts already in them and aligned. Wish every landing gear broke off like that. The only piece I needed to replace was the radiator underneath that was to crushed to repair.
The HH E-Flite electric retracts can draw fairly high current. We tested several sets not long after they came out. With typical 4 and 5 cell NMIH packs, the current draw may be high enough to cause enough voltage drop that the gear malfunctions and either give you a one down or one up situation. The gear can also get out of sync. The cure that seems to work is to use a separate 5A BEC and higher voltage battery packs.
We tried this on a H9 P-51 (ARF electric powered version of the PTS P-51, which has a CC 75A ESC. It's built-in BEC was not enough to insure proper gear operation.
The high current occurs as the gear mechanism moves a cylinder onto a point in the side slots. The current "spike" was greater for some reason when the gear was extending.
We did reduce the peak current by lubricating the slots and the screw drive, and slightly rounding the side cam points, as well as polishing the slots and adding a slight chamfer to the slot edges.

By the time you run all the servos and receiver off an Electric's ESC BEC there is probably not much left to run the gear. Lucky the BEC did not burn out and the plane crash.

I have 2 LiFe 2500 Mah batteries at 6.6v. This is more than they call for in the manual. The ignition is on it's own dedicated LiFe battery. I am thinking about putting a dedicated battery on the retract controller if this continues to give me a problem.

No matter what power supply you give the retracts, they will still stop on over load if the air speed is too high at any point during the retract cycle. The solution is to keep the air speed low until the gear cycle is completed

I have 4 LiFe batteries. One for the ignition, two for the receiver and one for the gear controller.

My electric P 51 B has 6 four cell LIPOs for the motor, two 2000mah 5 cell packs for the receiver, one 2000mah 5cell pack for the electric landing gear, and one 4 cell LIPO 2200mah pack for the Benedini sound system. Last Saturday I had 1 instance of the gear not retracting into the wing (left wheel) but didn't notice it had hung until I watched video of the flight. I have the ROBART electric gear installed. Gear down went normally and if I hadn't watched video I may have never known.

CuckK2 you seem to have some info on the electric retracts. I have the over current on 10 and the only way I can get the right side door closed is to take off go inverted on a 45 up line and hit the retract switch. That works and I have a separate 2200 mha bat on the retract controler cable. After four flights the retract battery took 120 mha and the 2200 running the receiver took a little over 1000 mha. why so little out of the separate retract pack I thought it would be more?

Is is this setup proving you with normal gear operation?

I'm going with 2 LiFe packs for the PowerSafe receiver (w/Tech-Aero IBEC for ignition) and 1 bateery for gear, if that setup is working.

Cheers

I am still waiting for the Spektrum A6150s and A7040s, that I ordered in March, to be shipped, I am wondering what substitutions are working for the A7040. That is the slo-mo servo for the gear doors.

I can get some Hitec HS5585MHs to substitute for the A6150s. But I am having trouble finding some slow motion replacements for the A7040s

It is Much harder to stall the gear with the battery plugged directly into the gear controller. Use a thicker wire as well, I have 18ga from the dedicated battery and use the thickest leads from the controller to the servos. These are at least 20 and maybe 18ga as well.

That looks awesome! Nice work. Let us know how it flies....although I expect it to be a great flyer.

I need some help I got 4 more fights in going inverted after take off to get the right side gear to go up. On the 8th landing the right gear partially collapsed, it looked like a folk wolf. Once on the stand I discovered the worm screw had come out of the motor. I sent it in to horizon and they sent me a new one. I got it in and the first flight yesterday same deal had to go inverted and this time it did not go up. It did come back down for landing. Put it on the stand to do some testing and I see the worm screw had come out of the motor, this was the new replacement gear. Of course before this flight i had tested it on the stand. So who can answer, it is obvious it is a manufacturing defect, but I called horizon and got no answers on the first one just a replacement. Anyone got information on what to do. Sending it in a getting it replaced seems to be a waste of time.

Do they sell an air retract unit for this plane?
