Default Recommeded Power System

.

Not sure of the brand of motor they sold him, but looks like a 3748-10.
AlexinFlight,

I believe that the following is from World Models web site and as they sell this motor separately.

Code No KM0374810
Specification / Size D37.2 x 48.5 mm
Package 1 pc/pkg
Description -Max Speed: 13860rpm
Kv (rpm/V): 770<-----No wonder why they ask for a 4S Li-POLY!
-Operating Power: 450W
-Operating Voltage: 8.5-18V
-Operating Current: 30A
-Peak Current: 38A (max. 15 sec.)
-Internal Resistance: 34 m ohms
-Diameter: 37.2mm
-Length: 48.5mm
-Weight: 172g
-Shaft Diameter: 5mm
-Mounting Screw: M3 (Front) and M2.5 (Back)
-Distance of Mounting Holes: 25mm (Front), 15.5mm (Back)

================================================== =

Too bad World Models does not specify the Idle Current Io for this motor as I could run some estimates! :o

The primary reason that I did not go with the recommended (and let me point out the operative word "Recommended") was because I wanted to have a light Mustang on my hands because of the careful inspection on the STOCK Retracts and I just do not feel that those retracts can take too much pounding from a heavy 3.8lbs. model no matter how careful you are on landing.

I fly at an RC Club with grass field so, I needed to have my model light for the final touch down to be as Slow as possible so, I would not tear up the main Retract gear.

Best of luck to your friend Jerry!

Carlos, just finished your full read on the mustang, great pics and informative as well. The plane is a beautiful representation of the "real deal" world models appears to be a quality company with attention to build and detail. How long have you been flying/building? just curious...

Roland,

I am glad that the Thread was helpful and I have been flying RC airplanes and Crashing since October 2002

As young as 10 years old, I did fly U-Control with those Carl Goldberg Stunt .049 Glow jobs as I just could not afford RC back then.

Have fun!

Hey Guapo,
With those new wheels in, can you taxi on the grass?
Thanks!

P.S- Very nice photos, keep posting more!

PvT,

I have decided to go back to the STOCK "SUPER LIGHT" FOAM wheels as came with the Model because I do not want to stress the STOCK retracts any in the future and so, they can last a long time.

The Hangar9 Super LITE rubber wheels are scale but, they are just too heavy in my opinion for retract operation, at least for this model.

I do not taxi on grass as lately we have a big problem with Armadillo created holes and do not want the model to nose over under power.

Hope this helps

Default Flaperons on WMP51

Carlos:
Have you tried using flaperons on your P51? My Spektrum 6xi will allow me to do so. I have set them up on my HZ Super Cub for testing. I have not had good enough weather to try them out in the air. Do you think that use of flaperons will help landing speed or is the plane able to handle well enough at landing speed as is?

No,

I have not setup nor used Flaperons in any model that I own and fly and especially this model.

I have made this model light enough that it slows down very slow and I do not need Flaps nor Flaperons.

Default Your Fault

guapoman2000,
It's all your fault. If I hadn't seen your video on You Tube and now your build thread here, my wallet wouldn't be as empty as it is now. I blame you for all of the fun this airplane will bring me. My fleet is complete (for now ....). I now have my two favorite WWII war birds (also have the PZ Corsair).
I couldn't wait so, last eveing I drove 40 miles to the hobby store that had one in stock and bought it. I'm all smiles now and can hardly wait for the motor to come in the mail.

Hey Rowdy

I just sent you a PM.
By coincidence I just got this same plane and no I haven't got it out of the box yet.
You planning on putting that Pulso motor on it (I am). I just got a 5 amp UBEC just in case I need it.

Man that is one sweet airplane..

I got a good friend that just ordered the world models AT-6 and Corsair. If they look anything like the P-51 I'm sure he'll be happy.
I also got the stock motor setup for the P-51 and I want to compare it with the Pulso 2820/12

Thanks for the info. I just replied to your PM.

I'm interested in hearing about your comparison between the two motors so, please report back.

Looks like great minds think alike. I know I'm going to enjoy the plane. Seems it's a popular one since guapoman did his pied piper routine.
Hope my motor comes in soon as I'd like to get a few flights in before I take her to an all electric fun fly in early Nov.

Which servo do you plan to use for the retracts. I've found one with 48 oz. inches of torque. It's the JR Sport and it's fairly small and will fit the compartment very well. According to guapoman's report, it should be enough for the after-market scale wheels.

I'll also take his advice about the spinner and servo thingamajig that slows the retract servo down.

I've never seen one before. It could be home made. Send him a PM and ask him.

I want to put a 3 blade or 4 blade prop on the standard Code No KM0374810 engine that is recommended for this plane. What size prop should I get using a 4s Lipo?

How about with the Pulso 2820/12?

Odie,
Pulso recommends a 12X5 with the X2820/12. I'm going to try an 11X7E in the beginning and adjust as I need. If it runs cool and powerful with the 11X7 I'll probably try a 12X5 ...if it makes anything run hot I'll go back to the 11X7. So for me, it's really an semi-educated wild guess.
Good luck wth it.

RJ
