Well I posted this question in the kit building forum and no one responded so I'll try here. The question was and still is: Does anyone own a Midwest AT-6 Texan with a G38 in it? If so, how much does your plane weigh and how does it fly? Mine has not flown yet and I'm trying to get a heads up on what I can expect. You can also check out my post in kit building dated the 17th. Thanks for any help.

I hope someone out there owns a Midwest Texan besides me!

I can give a little info. I've flown mine with a Supertigre 2000, weight was ~16 lbs. I still had to add weight up front to get it to balance, I don't recall how much. It was an okay match. Takeoffs were a little tricky but it was fine in the air. Make sure you don't try to horse this bird off because it will definitely stall. I needed a very long run out and shallow climb otherwise it would stall. I still have the plane but haven't flown it for 5 years. I'm thinking of getting it air worthy again and have considered using a G38 since I now prefer gas vs glow. I think it would be a great combo.

Hey, thanks for commenting. I added scale flaps and mine has the Robart retract system with two air tanks. No weight was needed up front to balance....but now it weighs 19 lbs. and this has me a little nervous. If I take off with full flaps down would that get me in the air sooner without risk of stall if I don't horse it up too soon? I don't want to run out of runway before it's airborne. It has 1000 sq. inches of wing area and 83'' wingspan. I think I can handle it once up in the air, it's the takeoff and landing I'm concrned with.

Sidenote of interest. I added G38 because I thought the Saito 1.20 which came with it was not enough power for a 17 1/2# plane....plus it needed a full pound of nose weight to balance.

I don't have flaps and I didn't find the landings to hot to handle, although I wish I had built it with flaps. Maybe I'll add them. I also have the Robart retracts, nice gear. I'm not sure about takeoffs with flaps. I would first try it without flaps. How long is your runway?

I agree that a Saito 1.20 would not be enough power @ 17 1/2 lbs.

Runway is about 600' or so. Woods on one side and open field on the other. No doubt I'll be aiming towards the open field. I'll just have to wait for a head wind of about 5 or 6 mph to help lift. I'm gonna find out this spring how it flies. Just trying to get some reaction from fellow modelers about my setup.

Hi All

I have the CMP AT6. Bassically the same model as an arf. I haven't started it yet, but will be using the robarts, and for power the OS 1.60. I figure I'll need a bit of nose wieght of course.

Hey this will give ya gas guys something to think about. I fly all electric and am just about to do the conversion on this Midwest Texan using a AXI 5345/16 electric motor. I will be swinging a 22/14 up to a 24/10 if i wanted to or if I had enough ground clearance. Its looking like the 22/14 is going to pull this Texan right off the gtound. I just maidened my top flight Stinson reliant this last Sunday using a smaller motor set up than what I have planed for the texan. As you all might know the Stinson has a 100" wing. Lots of people thought I was nuts for going electric but thats all I can fly where I live. Oh, I live in Huntington Beach California. Anyone interested in me boxing up a few million people and sending them your way? So do your gas guys know what your RPM's are or even close so I can get a better idea of what your pulling in regaurds to thrust? Any help would be great guys.

Have not tached mine yet. But should be a fun, if not wild, first flight when I get around to it. A 19# plane weighed dry, 1000 square inches of wing, 83'' wingspan and a G38 swinging an 18x8 prop.

Box them up and send them but make sure they're not illegal and not liberals. Well, then, I guess you better keep them.

Come on out and welcome to the east coast. But, I must warn you, we're getting a little crowded ourselves. I wonder if we will have enough acreage and open areas to fly rc in the next 100 years what with all the development going on. Scary.

Blade,
Huntington Beach area? As I mentioned in my PM to you, plenty of room to stretch your wings in the Palm Desert area....fly your Texan over the late Bob Hope's ranch. Just kidding - don't try it. Speaking of which, please let me know how much your Texan weighs after you've converted it to electric, batteries installed ready to fly. I think that a 24'' prop may be a little much for that plane.

bladerunner1955

My Feedback: (72)

You are right saying the 24" prop is too big for sure. I ment I could run one with this electric motor if needed. these electric motors are putting out some power now. The electrics do not have the RPMs of a gas motor by far so we have to make up with a larger prop and pitch. Seems to work out though.

My 80" Platt Zero at 18.5 pounds and flaps flys very well with a OS160 and 17x10 prop. You should have more power than required for scale flight.

bladerunner1955

My Feedback: (72)

carlbecker, Do you recall what your RPMs might be on the 17" prop?

carlbecker

My Feedback: (3)

On my Platt Zero:

I use 10% wildcat and about + 150' sealevel. With the Mezlijk 17x10 8.4k, with a Mezlijk 18x8 8.2k. I prefered the 17x10. I have not tried my backup APC 17x10 yet and don't feel the need for any more speed as about 1/2 to 5/8 throttle is good. I did set the radio up to give linear throttle response. The engine idles at 2k and peaks at 8.4k so 1/2 throttle is about 5.2k etc. Even at 18.5 pounds its not a brick, the glide at idle is fast and long when clean (dead stick landing gear up (problems), flaps up, reason was overheat problem) and a good floater with flaps and down elevator trim and a couple of clicks throttle. I had a Claude 80" at 17.5pounds with Saito 180 and APC 17x8 which also flew very well.

For comparision only - the Midwest AT-6 will be different but I image fairly close in wing loading and general performance. I hope I did not cause confusion.

outacontrol41

My Feedback: (9)

Well, thanks for sharing that. That's the info I was looking for. Not a brick at around 19# and good and fast glide rate. I installed my own flaps and intend to use them for every landing. How does it handle in the air? Set up to Midest's recommendations for high and low rates is the plane sensative or should I use some expo. to soften the feel? Also, does the plane fly much differently when the landing gear is up?

carlbecker

My Feedback: (3)

I may have confused you some. I have a similiar plane but its not a AT-6. I notice a bit of pitch change and drag when the Zero gear are down. I would follow instructions about D/R. Another plane I have is very different and very aileron sensitive. D/R may very well help on the maiden.

Sorry, I've got Texans on the brain. Both are warbirds so I suspect they have similar flight characteristics.

What ESC and Batt set up are you using. I am flying a aero works 260 50cc with Axi 5345/16 on 12 cells and a 24/12 Apc but it over amps the Jetti spinn 99 sometimes. I also get a weird timming sound at full throtle sometimes. lastly the Speed controler got to hot in a hard 3d run , shuting off the Esc for a second till I throttled down. Any advice would be a great help .

Ou7475 , I have not run the 5345/16 yet. And would talk with you about it. I have been using the 5330/F3A on 10 cells thus far with good results. Sounds like you are pushing it to the limits, and you should! They say it can handle what your putting to it so I wonder why it is letting you down? My Midwest Texan is all done ready for the last little thing,,,,engine mount and motor. I had a 5345/16 in mind with 11 cells and to swing a 22/14 prop possibly. Now, I am flying warbird style and not 3D. I also have just started working on the Sky Shark P-40. Repainted it today and started roundng up servos ect. I want to run the same set up as the Texan. The P-40 will be heaver in the 21 pound range and I wanted to run the 5345/16 in the less weight Texan before I do the P-40.
Ou7475, feel free to drop me a line at my [email protected] address and we can talk more about these monster electrics. I have about 50 planes, not all motored up but several are.

I have a Midwest AT-6 (actually paint in Navy colors... SNJ) and it weighs 19.5 lbs dry. It has three split flaps, and I have a OS 1.60FX in it for power. I am spinning a Zinger Pro 18x8 at about 8200 rpm if I remember correctly. It puts out about 16 lbs of thrust and flys the plane fine. I still have yet to figure out the landings... with full flaps the plane really pitches down when I pull the power back. Hope this helps.

Your plane is actually heavier than mine? And it flies fine? That's a relief! Have not flown mine yet due to winter wheather but I will soon. I built in two split flaps and I think that should be enough to do the job. I'll be turning an 18x6 as well. Thats a beautiful model you have there by the way. Looks like a shark out of water. Background mountain scene nice, too. Is this the first time you've ever used flaps before? Here's the trick: On down leg approach onto runway with plenty of altitude yet, with some speed built up cut the throttle and immediately apply full flaps. At this time the nose will pitch up rather suddenly. Give down elavator to recover and with nose down attitude bring her in for a smooth landing using throttle management only to keep plane level. That method brings my H9 Cessna in so slow you can run alongside it. The only thing that may vary is how or when you apply flaps. Half flaps used sooner may be easier for you.
