Just complete my build with a DLE-20 and E-flite electric gear. Motor fit completely in the cowl with pits muffler and stock motor mount. Final weight was 11 pounds with CG set at 3" from LE at fuse. Only needed 2.5 OZ of lead on tail to balance. Used 2300ma A123 battery mounted in rear hatch and used battery eliminator for motor electronic ignition. Very pleased with the build thanks to all the tips in this thread. Looking forward to her maiden, but probably will not be until early spring. Bottom line is that the DLE-20 looks to be is a good match for this plane. On to the next winter build project - 100" WS Yellow Aircraft AT-6.

Great news on your bird,, I have a DLE 20 in my Fleet Biplane and love that engine! She flies great and the engie should do you proud!!
Only suggestion on the bird, as I am sure you read, land with power! She will tip stall at slow speeds! but once I learned that the hard way I really enjoy flying the T-6A!
Congrats! I just got 4 flights in yesterday on my StrykerQ wierd winter in the Midwest - bu I will take any stick time!!

The weather here has been very mild as well. Hate to be un-PC but I am beginning to be a fan of global warming. The only down side is having to choose between working on my winter build projects and flying.
I also have a few other DLE motors (55 and 30) and have been very happy with them. I love my DA motors, but it is nice to have a lower cost alternative.
Thanks for the reminder on keeping the speed up on landings. I will probably use a steep glide path approach to the threshold to help me keep the nose down and speed up a little. I am really looking forward to flying it but will probably wait until after we roll our grass field in the early spring.

Finally started building my T-6. I acquired mine from Deuce77 last year and haven't had the time to start. I removed a majority of the covering and and will be converting it to a Navy T-6B which I flew in Primary Flight Training. I started on the wings, and modified them to have scale split flaps. I have enjoyed reading this forum. I will keep you all updated on my slow progress.

RE: T-6A Texan II 75-91 ARF build suggestions
I finished my replacement Texan II and had a chance to maiden it last weekend. Here's the video. I also have posted some pictures showing the end of the first one (too slow when turning to final - I did manage to salvage the outboard wing panels from the first plane - saving me a lot of time with the flap mod.) and after a speed run with radar gun showing 122 mph (current plane). I actually hit 123 the prior pass, but that number was erased. My setup is basically the same: Power 110 (295 kv), 10s 4000 mAh 30C pack, 100A HV ESC, E-Flite retracts, but this time I'm using an APC 14x14 two blade pattern prop instead of the APC 13.4 x 13.5 three blade pattern prop. This has made a significant increase in speed. I've got an aluminum spinner coming. I like that a lot better than the red plastic one.
One other interesting note: On Horizon Hobby's Texan II pages under specs, they now show the CG to be 70mm from the leading edge of the wing at the FUSELAGE! This is as many of us have discovered. I'm sure a number of planes were lost d/t flying at the CG recommended in the manual which was 70mm from the leading edge measured at the WING TIP.

Jeff - 122 MPH!!! fricken fast!!! I need more power!
Nice flying!! She is a fun bird to fly, and now that WE figured out the right CG (what is 3/4" of difference in CG [:'(]) She flys great
I wonder how many birds went down becasue of CG issues!!! Again we should talk class action lawsuit!
But the good news is the winter is been pretty mild here in WI and I have got some flights in with my Strykers, and Slick! cant wait for spring to fly my warbirds!!
Keep your wings level! and Remember a LACK of speed kills!!!

My T-6 had plenty of power with a Power 90 and 8 cells. I have seen a review using a Power 60 on 6 cells which reportedly flew okay. Of course, for a real screamer, I would bet the JW's 110 and 10 cells is quite impressive, although a little heavier.

JWJohnson, I noticed you used the Eflite 110. I was wanting to fly with a 90 and 8S. Do you think this is possible? I'm not looking for rocket speed, just scale. Thanks, John

It should fly well and fast on Power 90 and 8 cells. When Horizon started selling this plane they listed the Power 60 on 6 cells as the recommended power plant and the 90 on 8 as the upgrade. There are a few of us who pushed it further. They do now list the Power 110 as an option, but still have the 60 as the standard. As deuce77 said, the extra power comes with a weight penalty. I don't know how much most of the planes are turning out weighing, but mine with the Power 110 and 10 cell 4000 mAh packs weighs 12 pounds. The standard weight Horizon has on their web page is 9.3 pounds. Please build your plane with the CG at that now recommended by Horizon on their web page - 70mm back from the wing leading edge measured at the fuselage. The CG in the manual is incorrect. Quite a few planes were lost because of that. Even with a correct CG this plane flies like a warbird, not a trainer. If you get too slow it wants to fall out of the sky. As bob418 said above, "Lack of speed kills"! If you want to fly scale speeds I would either the power 60 would be fine, but your Power 90 setup should provide plenty of speed if you want to step it up some.
Good Luck with your bird.

Getting close...
Turned mine into a Navy version. The stock National Insignia decals are almost transparent, so you'll have to cover the red & blue Ultracote that will be under the white star of the insignia with white covering. I cut two half-round pieces of white Ultracote, almost the full diameter of the insignia and ironed them on before applying the decals. Saito .91S with stock muffler and Turboheader 90deg adapter. Hitec 485BB servos with Dubro heavy duty arms. RT-88 retract servos. I used a LiFE 1800mAh 6.6v battery. The airplane balances perfectly (70mm aft of the leading edge AT THE FUSELAGE) with the battery mounted lengthwise, centered under the rear cockpit headrest. Zero fuel weight is 9.2 lbs. Attached a pushrod wire to the entire length of the bottom of the ventral stab to act as a skid, in case the tail is a bit low in the landing flare. Dave Brown Ultimate spinner. Custom Dragon Models pilot. Hope to maiden it this week...

Thanks Bob.
Finally got the maiden done. Throws set per manual, w/dual rates. Balanced at 70mm aft of the LE at the fuselage, not per the manual.

- [*]Roll rate not very impressive on high rates; maybe I'll put a little more throw in there.[*]Power seems a little low with Saito .91S & MA 14x6 K series. I may put a Saito 1.25 in it. The power and maneuverability are probably correct for 'scale' flight, and i'm certainly not the world's most experienced RC pilot.[*]Very significant torque roll on go-arounds. Lots of rudder required. Probably because of the large prop and four stroke torque.[*]Nose gear will probably have to be replaced unless I can find a way to remove the slop. Steering is very difficult on the runway due to slop in the steering linkage at the nose gear. Also, lots of fore and aft slop when locked down. The mains are very tight and work well.[/list]Overall, an easy plane to fly...just don't get too slow on base or final. I stalled it in the flare and was suprised to see it stop flying at that apparent speed. Fortunately, it was so low when it stalled, it just plopped down on the mains with no damage.
I like it! It's definitely worth working the bugs out and everyone at the field comes by to take a look!

Great news, YESyou fly this bird slow and it will stall and come down hard, speed is your friend!
As far as the nose gear, there is a set screw that you can tighten that will take out the slop to some degree
But she is fun to fly!

Haven't checked in a while but I wanted to give you guys an update. I nearly have the wing complete. The split flaps took a while to construct but look just like the real thing. I hope they work well. I decided to go with the Eflite retracts and they dropped right in. I went with a .90 Eflite motor and have it mounted. I will continue to post pictures when I have time.

After reading all the notes about the weak nose gear steering arm, here is what I've done. Remove the tiny threaded pin and drill out the steering arm and the sliding link using a slow speed drill[ to prevent melting the plastic]. By using numbered drill bits slowly increase the drill size up to a # 32 bit. Then you can use a 4-40 1 1/4 " socket head high strength bolt. There seems to be plenty of material if you go slowly and take your time drilling. I have pictures of this, but I can't figure how to post them on this site yet ! I can E mail them if you want .
