It's already end of season here in Dubai and the weather is getting very hot for flying.
And the main reason is I don't have time for flying any more bcz I'm going back to college and I don't have spare time unfortunately
The plane still new and flew just once for test flight.

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.

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.

After the dead stick landing on my maiden with only one gear down I have the new landing gear back from HH. They did not find anything wrong with the right side main which did not come down prior to the engine quitting. They did send me a new set of gear though at no cost. 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.
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.

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.

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?

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

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.
