Build Review Can you help me identify this aircraft?

So, I just bought this plane in need of TLC for what I thought was a reasonable price.
It has 4 Airtronics servos in it, but no receiver. I already removed the fuel tank that was in it.
It was obviously a nitro powered rig at one point, but I thought it could be converted to a brushless setup without too much trouble.
It's definitely built from a kit, as there are markings on some of the parts inside the fuselage.
It has a 44" wingspan and is 28" from the engine plate to the end of the rudder.
It has a poorly done monokote job. Can the wrinkles be taken out of it with a blow dryer or a heat gun?

I'm guessing it's possibly a P-51 Mustang?
Does anyone have any info that would be helpful in the process of breathing new life into this bird?
Being a total newb to flight, this would definitely be a long-term project that won't see any flight time for several years.
Any and all help would be much appreciated!
Thanks. Rob.

Definitely an AT-6 Texan, and not a P-51 Mustang. Not sure about the manufacturer though, but it has to be an older nitro kit, maybe for a .46 size engine.

The wrinkles should come out with either a covering iron or heat gun. A hair dryer could work in a pinch too.

Any idea of what it currently weighs? If you are looking to convert it to electric, I'm sure smaller servos would work (like a good 17-gram servo) to help reduce some weight. But if it is a built up gas kit, it's going to most likely be heavy and have a high wing loading. But it is definitely worth looking into!

Looks like a Texan to me.

Most old birds can be resurrected. The weight would help in trying to figure out what motor/power system would be appropriate. You should be able to get the wrinkles out with heat. Be careful to not overheat the covering because it will melt if heated too much. Keep the heat gun moving and start far enough away...

Definitely a Texan...

Need to check something.

I have the remains of an unfinished kit (half the wood missing) someone gave me that might be the same one.

Nope... mine is 54 inch span

Hi Rob, here is a motor and ESC combo for your plane, at 49.99 you cant go wrong, it will be more than enough power for your plane.

Before I forget Check the size of the Cowl, make sure the motor will fit into the Cowl on the Plane, Buy the Biggest motor that will fit into the cowl, reason Being is that E Power comes out lighter than Nitro, and its best to use a bigger motor than having to add Dead Lead weight to get your CG correct, I have always had great luck using the biggest motor that will fit into the cowl, and I dont have to add any Dead weight, Buy a Motor with around 1000KV + or - 10% will be fine with the KV, here is another motor if the motor i listed is to big for the cowl, If you need a cowl, a soda bottle bottom will work, Rob, I would like to see you flying this Plane by the End of Febuary 2014

Thanks again CHELLIE!!!
I like your thought process, BUT.......

I now have a grand total of 60 seconds of flight time, so February of 2017 is probably a more realistic estimate of when my flight skills will be honed enough for flying a plane with ailerons....

I bought my first plane ever, a Hobby Zone Champ, last week.
After the first 60 seconds it looked like this:

The cowl of the AT-6 will be big and round... if you use the biggest motor that fits it will be extremely nose-heavy.

Yep... glue that little cub's wing back together and maybe some clear packing tape. It will be fine.

So, I took the Champ out for it's(and mine) second flight this morning!
I managed to get a full battery charge out of it and only crashed it twice!!
Roughly 20 minutes! YAY, me!!!
When the battery died suddenly, I was recovering from an incorrect stick movement and was at an altitude of roughly 20 feet.
I didn't have time for corrective action and she crashed down on the frozen grass.
Who knew that frozen grass would grind the foam and snap the threaded part of the prop shaft off clean.... LOL
Live and learn!!
Time for a trip to the LHS for a new gearbox....
Today's carnage:

Today's carnage:
it looks like you have some prop shaft sticking out of the gear box, if the shaft is not bent, you may be able to get a prop adapter for it, with the rubber band prop adapters, leave 1/8" of the shaft sticking out of the prop adapter if possible. you will need to measure the shaft dia size. sometimes you need to drill the back side of the prop so it fits flush on the prop adapter.

Full,
Might consider an Apprentice S with SAFE. That Texan will be a handful as a second plane IMO.Notorious tip stallers.

If you want to go cheap, get the parts for the PZ T-28 and put it together yourself-~$100. A great plane. Add a Hurc Powerup motor & esc 4 9g servos and you'll have a plane that you'll never get bored with.

Also, read Ed Anderson's ( AEAJR) " Everything you need to know about electric flight"

Welcome to WF !

And do whatever Chellie tells you!

If you're going electric, a built-up Texan will like the gear and especially battery far forward. I relocated the battery on the electric HOB Texan kit, to balance with a lighter lipo, since it was originally designed for round cells. It required a good bit of lead with the round cells, that were mounted a bit further rearward. It flew with a geared speed 400 on 3s lipo, but lost interest since it was not an exceptional flyer, and propping for more than marginal power would really stress the brushed motor.

Looks like the rear fuse has been crushed a bit, and could possibly be repaired/braced from a small opening cut into the fuse bottom, after slitting and peeling a bit of covering back. I wonder if this was a pure scratch build, given the slightly off-scale shape of the rudder? Haven't seen any plans for 44" span.

Canopy is a proper AT6 style vacuum formed that looks mass produced and the correct scale. That points to ARF/Kit or maybe a "short kit" (plans, some of the die cut/laser cut parts and vacuum formed parts, get your own sheet wood and sticks.)

There have been MANY different AT6 ARFs, kits and short kits over the years...

The partial kit I have is by Kyosho (maybe 30+ yrs old)

Today's carnage:
Nope, you don't need a gearbox, just the prop shaft with the main gear pressed on it. Super easy to replace, grab the retainer (white plactic pice at opposite end) with pliers and spin the big gear till the retainer comes off (don't lose it) slide the shaft out, replace with the new one, then replace ther retainer. Takes 3 minutes....

I'm either going to get good at flying em, or get good at fixin em!

Thanks everyone!
It's definitely a kit of some form, judging from the markings on the pieces.
Notice the "D 23" markings next to the lower servo.
Yeah, the fuse has some damage, but the crackhead I bought it from said he pulled it out of a dumpster.
As rusty as some of the screws are, I would say it sat in the rain in said dumpster, and the damage is from the wood being soggy.
That would also account for the water stains inside the fuse.
