What is the set up for aileron and elevator throw on a P 51 ?

Doesn't need a lot of elevator, unless you like high speed stalls. What size Stang are you referring to?

Control Throws This will give you a starting point for the control throws. Set these measurements as high rate, set a low rate at about 70 percent. Add about 30% expo to high rate and 20% to the low. After the first flights you can adjust to your preference.
Ailerons 1/2" Up and Down
Elevator 3/4"Up 1/2"Down
Rudder 2” Right and Left
Flaps 15 degrees for take off 45 degrees for landing

I saw your post on your p-51. I am building a Ziroli Mustang and wondered how some build and operate the inner gear doors.

Default P51 Gear Doors

I don't see anyone answering your request, so I thought I'd respond with what I did.

The gear doors were made from resin/fiberglass before I cut out the bays to ensure conformity to the wing.


I added balsa and plywood to create the door details from pictures.


I used ball-link hinges simulating the full size door attachment.


I guessed at the micro servo needed to actuate the doors.


The doors were fitted and the programmable Hitec servo's travel was pre-set and tested adjusting linkage as needed.


I made a YouTube video and posted it's operation which is controlled by the Century Jet control board. The board can now be bought separately from the manufacturer.

I have a build log on this website for more details.

At least this is one way to do it. Good luck.

the day finally arrived!
the Maiden of the GG P51

3 flights

all went well.

Take off and landing was not as handful as I was expecting.

Thanks for the pics showing operation. I'm squared away on my retracts. Do you use all electric?

on my CY model P51, i use the CY retracts, which are very good.
I use a Robart for the tail wheel.

on MY CARF P51, I use electric retracts from Sierra.

on my CARF P47, i uses pneumatic retracts from sierra.

Sierra does not make electric retracts for the P-47

I was at Bomber Field last year, and I got to meet a great number of pilots, and I asked many questions.

One of the questions I asked the war bird aficionados??? What do you prefer?? Electric retracts or pneumatic retracts??

One of the pilots, whom had a razorback P-47 with a Moki told me he much rather prefers pneumatic retracts for the following reasons: he says if he deploys the retracts to land, and then something happens where he has to abort, he says you can save the retracts by pulling them back in and up and doing a belly landing, and that pneumatic retracts can retract very quickly. He told me that electric retracts are quite slow and may not get you there as quickly.

In my very limited experience, I like the electric retracts becuase it almost seems to me that they are more reliable?? May not be true, but seems to me that I see a lot of guys with ROBART pneumatic retracts that fill the tanks up right before take off, and many times, they come in for a landing and one retract does not extend down???


I am definitely not an expert, and my knowledge is very limited regarding war birds, maybe someone else will chime in and answer your question.
