Top-Flite T-34
I've just completed the lower half of the fuse and am mounting the horizontal stab.Be sure to check your incidence on the stab,it is supposed to be +2.Mine required the saddle to be sanded down a bit to meet the proper degrees.PT21flyer,do you know what servo's your planning on using?The planes show all standard types.I'm not 100% sure that would be enough.On the right thrust issue,I think I would rather keep it in there,after all by just trimming to compensate for the P-factor and thrust etc you'll be creating a small(probably hardly noticable) amount of drag to overcome the above factors.I also realize you said the full scale doesnt have it built in,but why not use it on the model.Once the cowl is on how will you notice it?I'm not nit picking here in anyway,just curious.

Answer Questions
To answer some of the questions posted:
In all the models I've built, I've never used right thrust. The only time I've ever noticed it is when the plane is slowed down and if you fly all yhe time with rudder, it really makes no difference. Flying twins, like I do, You have to be able to fly rudder all the time. Besides, I don't like the prop and spinner being crooked.
Thanks for the heads up on the stab incidence cubflipper02. I'll be sure and check it when I get to that point in construction. I'm planning on using standard ball bearing servos on everything. On a plane this size, I think they should be able to handle the loads okay. In my 31 lb. Islander the only giant servos I used are on rudder and elevator and I do loops and rolls with it. I've never had any problems. I fly Airtronics and the standard servos have 50 oz. in. of torque.

Wing Bottoms Sheeted
I got the wing bottoms sheeted and in this picture the sand bags are holding laminations of 1/16" balsa and 1/32" ply to the shape of the wing bottom to be used as gear doors.

Fuselage Begun
Here is the beginning of the fuselage framework. The bottom is built first. Waiting for 60 minute epoxy to cure on the firewall.

Fuselage Progress
Here is a picture of the fuselage bottom with the side sheeting installed. It can be removed from the table now as it is rigid. Stab saddle also installed. Working on hinging stabs and finishing them so they can be installed next.

Stab Hinging
This drawing and picture show how I modified the control surfaces to use Robart steel pinned hinges for a gapless installation.

Engine ready to start breaking in.
This is my ASP .91 mounted on a test stand so I can start running it to break it in. I've put an O.S. .91 remote needle valve on it so I can avoid holes in the cowling. Will also use a remote ni-starter and refueling probe all located in the nose wheel well. I'm going to build stainless steel scale exaust with the attenuator pipes. I'm hoping this will make it sound a little more scale too.

Back Working On T-34
Well, after about a two week break, I'm working on the T-34 again. I've been hinging the gear doors and glassing the stabs. The picture below shows the templates I designed and printed with my CAD program for routing the scale stampings the real aircraft had on all the magnesium parts to act as stiffeners.

Set-up For Routing
This is the set-up I used for routing the indentions. I'm using a 1/4" round nose carbide cutter in my Dremel Tool with a router attachment. Just to the right of the Dremel you can see one of the grooves I've routed.

Top-Flite T-34
Looks good. I just got a old byron T-34 today. Im not sure when ill start to work on it, itll be a heck of a project. Dad told me retracts were only $350. Ive thought about selling it so i could buy the T/F edition , easier to build, instead of fiber glass and foam, but this is also a plane ive always wanted.

Top-Flite T-34
I have been watching this thread and I have made a few mods to the Top Flite plans.
First I did not like the fact that the fuel tank was mounted sideways and would be difficult to remove , if necessary. This also is true for the throttle servo and linkage. I cut a nole in the firewall above the retract servo. I then have access to the area behind the firewall. I also added a floor for the tank that is across the entire fuselage. In the area I have installed the retract servo, retract valve and the air tank. I then made a box that serves as the engine mount (FT90 Twin) and inside it I have installed the throttle servo.
I also installed the rudder and elevator servos perpendicular to the fuse to make them much more accessible.

Picture of T-34 fuselage bottom. Also note the different retract mounting. I built wheel well sides upon which I am going to mount the nose gear doors. This picture also shows the different arrangement for the elev/rudder servos.

Easy to build
Dago Red,
I think it has been fairly easy so far. I've made it a little more difficult with some of the changes I've made to it. If it were built according to instructions, I'm sure it would be easier. But then everyone has different tastes and ways of doing things.
