Hanger 9 1/4 scale Tiger Moth electric conversion

Post

Hi all, 
I just fixed the rudder and moved the 4200mah NiMh receiver battery below the aft cockpit. All that needs to be done now, is rig the flying wires and make the wing brackets for transporting them. Maiden flight will occur soon!:thumbs:

You have a sound system so it sounds like a tiger moth? Or a two cylinder inline four stroke. Oh, yeah that'll do it. Should be a nice slow scale flying replica.

1/4 scale?  Must be big, is that about 2 meter wings?

The "Tiggie" has an 88 inch wingspan and weighs about 17 or 18 pounds. It hasn't been weighed yet. The power system puts out about 20 lbs. of thrust. I'll be taking it easy on the throttle! :lol:

Impressive.   A conversion to big electric or just a gas motor?

Well, it was supposed to have a 30cc engine but I converted it to electric with the AXI 5330/18 from the Monster Pitts. It swings a 20x10 prop. It should be ready to fly soon , as soon as I get some time off.

Looks like there is more rigging work to do, so it won't be flying tomorrow. Soon, though.  :'(

The Tiger Moth is ready to fly. I had to install the "X" wire braces between the wing struts for rigidity. Funny thing, Hanger 9 did not have them installed in the instructions.
Now, I have to work until Thursday. Drats.

Fellow aviators, the Tiggie flew today and did very well!
It took 2 people to put the wings on, comfortably and the flying wires needed some tightening after the first flight. I guess that was to be expected. It flew beautifully. It was very stately and sedate. Stable comes to mind. It most definitely is a trainer, yet it rolled and did large loops with the greatest of ease. It does Hammerhead stall turns quite well. The slow fly-bys were so slow, it looked like you could reach out and catch it. It flies very realistically as the full size one does. It does have a bit of inertia, as all big birds do but it is very gentle in nature. It would make an excellent trainer, by gosh!
         The minus list is relatively small. It definitely needs rudder input along with the ailerons for a coordinated turn. This airplane will fly all day on just rudder and elevator alone. It likes the use of it's rudder and teaches you to use it. It has a steerable tail-wheel but the rudder is so powerful a tail-skid would work just fine.
      The motor installed in the Tiggie is overpowered. It could fly with half the power it currently has, quite well. If one was to make a scale take off, the application of throttle brings the tail up almost immediately. The rudder takes care of any directional issues with authority. When the power is smoothly added, the airplane was off the ground in 20 feet. A good amount of right rudder was used for a 3/4 power take off.
    In level flight, It was cruising around at 1/4 throttle just strutting her stuff. Quite remarkable for an airplane of this size.
          On the other hand, with it being so overpowered, it might make a good glider tow plane. It flies slow and it flies fast enough for most gliders. The landings were a cake walk. It comes in with a touch of power and it touches the main gear with a kiss and throttle off to let the tail down to the ground. Don't force the tail down or she might just start flying again, unexpectedly.
        It truly is a kite and a good flying one, just not something you would fly in too windy of conditions.
It's a keeper.  :thumbs:

Excellent and congrats.    Is always good when a maiden goes well and the plane performs great.

Bummer, probably will be doing household errands wth the wife. It needs the motor, ESC to be programmed anyways, it's making a squealing noise at half throttle.
