Top Flite Spitfire Mods for better cockpit details(???)

I realized that the world needs another one <NOT>. But I did want to document some of the modifications that I'm planning to incorporate. Mainly, I want to open up the cockpit area for more scale-like features. This will be the first time for me, not sure if my expectations will workout with reality, but hopefully you guys will keep me motivated and have some pointers.

First some background. For whatever reason British WWII fighters are my favorites, specifically the Spitfire, Hurricane and Mosquito. Once this Spit is done I have plans for a 70" Hurricane and plan to do the Brian Taylor 81" Mossie. Lately I've seen a flurry of Spit's at our field, starting out with New2rc's electric one, a WM one, and a GP. Still haven't seen a H9, though like most ARF's versions does not look quite right. New2rc's is probably the best one I've seen personally by a fellow club member http://www.rcgroups.com/forums/showp...&postcount=581 He put in a lot of work into getting scale retracts working and in the right position! Tower offering the Spit on the Easy Pay plan tipped the scales, and had to have one!

Before I get on with the build thread, here are a bunch from the net, for those thinking about starting one.

As for motivation part, see my RCG blog for links to other stuff I'm into. I'm fickle, work from project to project and eventually something gets done!

Ok, on to the work. I think it was Dave Platt who said the cockit area was no man's land for r/c stuff. I was some what disappointed to see that TF did not take this into account, but purchased the thing anyways realizing that the overall the kit would be an easy build. Started with the intent of hiding all of control horns as some have done in the above threads, but as I got into things figured it would take me forever and limited myself to the cockpit and exterior panels (I hope!)

I've built the rudder and elevator according to the instructions, and though the wing is the next step, skipped to the fuselage. First change was with the cockpit "floor". I chopped off the rear, since it not present in the real Spit. I used the remaining piece to help position the formers between the shelf behind the pilot's head and the instrument panel.

Stock, the kit only has a 12oz. tank. Since I'm planning to put in a .91 four-stroke, felt this was not enough. My .91 Saito has a 16 ounce tank good for about 8~10 minutes at full throttle. I decided to extend the fuel tank area about an inch. The kit's pieces for this area are on the sides of the fuse, the ones I remade are already installed. If you look real carefully and use a bit of imagination, you'll see that TF supplies one very long motor mount. Have to make a new top cover for this area.

Servo tray should have been glued in at this point but only present currently to space everything out correctly.

Let's swap notes.

I'm about to restart on mine at the weekend. I'll have some tips on wing building to share....

Sounds good Saint.

Remember though, as mentioned earlier, IMHO felt the TF Spitfire has almost been done to death on-line, so I'm only planning to post areas were I've modified the bird to make it more scale looking, at least in my eyes. I've already done the fins, came across problems others have experienced, but haven't mentioned them just because it was old news, for example. So what I'm trying to say is this thread probably won't be the best place to look for problem areas with the kit. Feel free to ask any questions though.

About the only modification I'm planning to do with the wing was done by one of the guys over at RC Scalebuilder. He put the air tank for the retracts in the center of the wing. Hope he doesn't mind, but I've blatantly borrowed one his shots for post here.

Sorry I haven't posted anything additional. Just other stuff getting in the way. I have sheeted the fuse, but thought that some of the lines were wrong and thinking about ways to get around that. I do have a couple of more pictures, I'll get them up soon.

So, how much more do you have to go Saint?

Lots to do.

Basically all i got done before being distracted by life the universe and everything was to get the fin stab and elevators made.

IC, but that is still 3 steps closer in from the edge of the universe and the project is in motion

For those not familiar with the model, the fuse has 2, c-channel stringers which are pinned to the building board first, to which the formers are glued. A smaller stringer is glued into the channel to form a shelf for the sheeting. If you look at the manual in the background you'll be able to see the setup further, along with the pictures uploaded previously.

Unfortunately, this c-channel is much too thick and prominent for a scale cockpit. Decided to omit this, and replaced the smaller balsa stringer with a spruce one. I needed to build up some courage since it would weaken the fuse and would have to build it back later.

Frank, looking good!

You are doing the full scale retract treatment .

That will be so awesome. Looks like you will have a nice forward rake on the gear which should mitigate the wonderful nose over fun.

First pic shows the plywood piece I cut out of the fuse on top. This would have made a nice arm rest for the pilot so it had to go. This shot also shows a reinforcement piece that needs to be cut off at the bottom. This is to help compensate for the plywood, but also act as a stiffner for the top and bottom formers. Other shots for illustration, pushrods and antenna tube are installed and will be hidden by sheeting.

Yup, as you probably remember, not having retracts in the "scale" position are detracts for me, enough so for me to build one. TF cheats a little by having them a forward and out from scale but I'm sure you'll agree that this is much better from an r/c standpoint

See ya!

Disaster strikes. Well, sort of. Using the info in the previous pdf, and a couple of Mk1 models I have as a guide, I tried re-shaping the area behind the cockpit to a more realistic profile. Unfortunately this resulted in going through the sheeting. Since this part of the fuse bothered me a lot, well, I decided to go further and thin this portion down. I realize this is a sport scale model, but this portion bugged me a lot. Left side is stock and the right side the modified shape. Last picture shows rework start on left side and the new stringers for the right side. Basically sanded down to shape past the stock stringers then added new stringers to the re-shaped formers then sheeting added.

The guy in the following link is making a full size Spitfire cockpit for a flight simulator, it includes a lot of nice details shots, so I've added it here.
