Pic #2

Are there any other pics around of how he set up the bellcrank/leadouts?

I have a 46-size Hangar9 P-51 that I want to convert, and am looking for ideas on how to set the controls and, "maybe" still be a take apart wing.

Thanks, Larry

You can use the typical RC style design, 1 or 2 dowels from the wing that go thru a former in the fuselage and nylon screws near the trailing edge to hold the wing in place.

Looks like he is using 2.4 Ghz for the throttle, retracts and flaps, makes it easy to install and make work. I have multiple models that all use the same transmitter. I made a clip that goes on my belt to hold the transmitter.

This is our club website with information on CL scale

Look at this video I shot of my RV-4 that shows the removable wing

Great looking P-51 that Bill was flying....!

Brodak Fly-in will have CL scale June 16-18, 2016. Bill would do well at the contest with the flaps and retracts

Fred

I believe Bill has taken it to Brodak but was unsuccessful in putting up a flight. And that is correct about the 2.4 Ghz radio system that he is using. I will talk to Bill and get all of the paticulars for the model.

That would be great ... !!!

I will take a picture later today of how I do that that

Pull the elevator servo out, drop in a Bellcrank, replace the older receiver with a 2.4 Ghz receiver, add the line guide and you are ready to go. Same airplane, engine everything stays the same as with the RC mode of operation.

You are right the bellcrank location is not that important, the CG and leadout guide location determine the line tension. You can convert this model to CL scale easily

I have been able to make models that have been flown as RC or CL model with a 5 minute conversion

I posted the leadout guide as a separate post in the CL scale section.

As promised here are the specs for Bill's Mustang;

P-51D Mustang Scale model Specifications
General:
•   The model is a scratch built semi-scale P-51D Mustang built primarily for Fun Scale contest events. It took about 3 years to build.
•   Set-up as described below has very good high speed, low speed, touch-and-go, and stopping on ground while running abilities
•   SOUNDS GREAT TOO.

Size:
•   Wing span = 72”
•   fuselage length = 51”
         
Engine:
•   Magnum .80 four-stroke
•   Uses 10% Nitro / 20% Castor (as specified in engine specs)
•   8 oz plastic uniflow tank (gets about 7 min on 5 oz)

Operating Surfaces:
•   Throttle control
•   flap control
•   main gears retractable
•   tail wheel retractable (retracts forward – separate from main gears)

Weight:
•   approx. 7 lbs   
   
Radio Equipment:
•   All operating surfaces controlled from 2.4G equipment:
o   Receiver: Spectrum AR600 (6 chan)
o   Transmitter: Spectrum DX5E (5 chan)
o   Battery: 1500 mAh, 4 cell, 4.8 V

Lines:
•   2 lines - 0.021”D X 65 ft

Unique features:
•   Has approx. 2-1/2 in dihedral with lead out wires coming out below the center of the tip to keep the plane level.
•   Constant voltage on glow plug at all times in flight with rechargeable 1.5V battery switching sys.
•   Small amount of rudder controlled via “Mandakis” bell-crank system (i.e. small crank controlled by elevator push-rod); slight right rudder on down control and neutral rudder for up control. This was added just to demonstrate an additional control of an operating surface.
•   The wing is balsa covered with the entire plane covered with silkspan.
•   There is carbon veil on top and bottom of the wing past the main landing gears for additional center wing strength.
•   Of course, because of the size of the plane, the wing is detachable. The leading edge is held by 2 large dowels and the trailing edge is bolted down with 2 metal bolts.
•   The Mustang bottom radiator assembly is a separate attachment by a bolt.
•   Ink-lined as authentic as possible to real Mustang.
•   Finished as the authentic Tuskegee airplanes (i.e. red-tailed).
•   To keep with the Tuskegee theme, the pilot is an African-American flyer WITH a black mustache (as approved by close black flying friend).
•   Parabolic spinner as specified for real plane.
•   With a small amount of effort, the entire cockpit can be removed from the bottom of the fuselage.
•   I say again: SOUNDS GREAT TOO.
