Another Cox .010 converted to R/C & P-51 Mustang. (Flight page 5)

Meanwhile I made some consumption comparisons between engines.
cox .010
operation at maximum speed 26950 and 27150 rpm time: 9 minutes. I was surprised that it exceeded 27000 rpm!!
cox .020
running at maximum speed 17550 and 17850 rpm, time: 6 minutes.

ohhh i made a mistake!

As a matter of experience a few days ago I installed the rear of the Micro P-51 in the wrong place, when I saw the photos I realized my mistake!, so...
What would you do? Would you leave it where it is or would you change its place?
In my opinion, I think it will work better where it is, but YOUR opinion interests me, thank you!!!

60 years ago, they had a term called, "FLYING SCALE". This meant that overall, the model was to scale, but certain changes were made so it could fly better. These included enlarging the rudder and elevator size, increasing wing dihedral, and other minor changes.

I'd say that although the tail wheel would not be in its scale location, a move to the rear to make it handle better is in the same spirit of FLYING SCALE. You are not working toward a historically accurate model, just one that can be recognized as a P-51. So far, everyone who looks at it says, "Sí, yo veo un avión P-51 ahí." Eso es más importante, ¿no? That is more important, no?

I agree with George. It will be easily recognizable as a Mustang; the vast majority of folks will never notice the difference; the longer tailwheel moment should help with tracking. Leave it and build on!

okay guys!, we close there!, it stays as it is now!
I liked your point of view and comments!
Thank you!!!

So the Micro P-51 Mustang is ready to be coated!
the team will continue to work!

Very beautiful I can't wait to see the color combination will be chosen for this cute plane it is small and would need bright colors for it to be clearly visible

Mauricio, what amount of fuel was burnt in the engines? 10 ccm? Also, you must have used a large prop on the 020..my 020 spins the stock 3" 3 bladed prop at near 24k..

Very nice Mauricio

Great pic, how much does it weigh as shown?
What is the combined weight of the RC components?
The TD .010 looks scaled in with the plane size.

Thanks for the feedback!
David, you've hit the nail on the head! Actually, it should be coated with visible colors, so that the model is totally identifiable in flight, easy to interpret during maneuvers and from a distance, especially because it's like you say, it has to be easy to see. , now, the issue is that the color of the Mustang, in general, is metallic aluminum with other agreed colors, so I am deciding what to do, exactly what I am going to do.... in short, I have to decide.
The chrome metal color would go wonderfully, but it is a color that reflects the sun, making it look like a flash or spark in the sky according to how the sun strikes it....well....I have chosen a decoration in particular, but I still think so for the above reasons expressed here!.

András, the amount of fuel in the test is 12 ccm.
The prop I used in the test is the 2-blade 4.5 x 2 gray thimble Drome (hard)

Thank you very much friend!
The weight of the model (frame) + Cox .010 rc + rx + fuel tank + 3 micro servos + 1S battery + propeller + landing gear + ignition key + cockpit = 121 grams = 4.26815 ounces.

what do you think??

My friend András, here is my experience with Cox .020 and three-blade cos propeller for .020

Ambient temperature: 14 degrees Celsius
Humidity: 31%
Propeller: https://coxengines.ca/propellers/cox--020-propeller-3-125-x-2-5-3-blade.html
Fuel tank: 12ccm
Nitre: 30%
Max RPM: 21140
Time: 05:47.97 minutes

Yes I agree the metallic color would surely make it shine bright like a camera flash The red tail would be a little the same problem despite the yellow and not my favorite color I think kentuky air or the shark face would be my choice the yellow has always given good results in terms of giving me a good visual for orientation à yelow rear red in the front I would change them a bit from the original color without changing too much

Well friends, I still haven't decided on the decoration, I took a look on the web to see some alternatives and I found these, they have a very nice appearance too!

Nice plane look that black n Red looks like a racing plane

Mauricio, both color schemes are nice...I would go for the black and red though, because this is much simpler to do, then the tiger-striped one..but I know that nothing is impossible for you!!

I was going to suggest a Reno livery. Or, make one up. I've done NASCAR on a few models. Electric and 1/10th car decal sets was cheating, however.

thanks guys for your comments and trends!...I think I've already decided , it will be a surprise!

I'm giving colors to my Micro Mustang....I don't have much free time, but as I can do it I'm progressing....it looks beautiful!, but I'm not going to show anything yet, hahaha.... expect!...

We are waiting for the color scheme No doubt that it will be interesting one

Friends, I invite you to guess what was the decoration chosen for the Mustang P51.
I invite you to guess....
What do you win?, nothing, hahaha... a Lap in P51, hahaha
On Friday I will remove that rag that covers the model!... Good luck!
