I'm about to order the RDS-control system (Rotary Drive System) for the ailerons, but need to know how much the ailerons on the Corsair deflected in degrees if possible.
Anyone have any pictures from a flyable Corsair with ailerons deflected max?

Cheers,

The TF corsair calls out for 15 degrees of travel. I know thats not a 1/6 scale, but its all I know

The 15 degrees works out to be about 1/2" of travel

Thanks Chilie,
Thats why I asked for a deflection angle in degrees, as it's independent of scale

The reason I want to know the aileron-deflection (in fact I want to know the deflection of all movable surfaces) is to have one more scale-item to reproduce for the scale-judges.
The deflection I need for flying can be programmed easily.

Cheers,

I make no promises that the information I just provided was "scale". That was just the information that is in my manual. I have no real idea how many degrees each of the control surfaces move on the full scale.

A Paul Matt drawing shows "50 degrees max flap deflection". Another Vought factory drawing shows the same thing.

[image][/image]Don't know if this is full aileron deflection, but it looks more than 15 degrees.

Boy! I just have to say it is amazing what information can come up here! I have been kinda sitting out a bit. I want to build the TW as becoming finalized here, and the tail kit (fantastic). We will all come up with something worthwhile here, no doubt! I won't post much on my TW and build on the tail, when I get there(unless informational), everyone is doing so well. Thanks to all with their ideas. I'll use some great ideas here, that is what it's about.

Chad, I think maybe add one stringer per quadrant on the fuse? Just my thought, I want to experiment with thin sheathing, as you know. I don't know how many are thinking with me. I want to do something different, yet actually traditional with the thought. It must go back to my rubber power days... -Eric

Nice going as always Richard, and others with facts. Why are we talking about "scale" surface deflection? We are two years away from the best models here. Those amongst us that are going to build and fly in months could do that with a TF? I may have missed something? This is truly not an issue for us now? Not to be a pest. Our planes must fly on a different measure than the real one and scale surface deflection really isn't important except for a static display on the flaps in my opinion.

Riddle,
If there is something I don't like is not being prepared, I hate having to look up things I will use later in the build at the last moment.

Unlike all of you guys in the USA, I have to plan well ahead to get all the stuff I need in time, thats why I am already ordering the RDS-system for the ailerons.
It is available in 2 versions, one with a 45 degree bent and one with a 32 degree bent.
The reason I need to know the max. deflection is because I would need a much higher-torque server for the 45 deg RDS, so if I can avoid that I will.
Looks like the 32 degree will do just fine.

I know I will probably not fly the Corsair with scale deflections, but I want to have the ability to use scale deflection by licking the dul-rate switch on my transmitter.
It might earn me some extra points with the scale-judges.

Cheers,
Danny "Remklep" Busch

P.S.:
For those interested in the RDS-system, a pdf explaining the system with building instructions can be downloaded here: RDS-Rotary Drive System

For those not wanting to build it themselfs, like me, it can be ordered here: irfmachineworks - RDS

I here ya Danny. I don't think the judges will give you any points for scale surface deflection though.

I am thinking ahead as we all are, too. This should be a great result here!

Edit: Danny, sorry not to know how difficult it may be to get products there. Shipping isn't cheap here, so I sympathize. You are closer to my Laser engine maker though. Isn't there an Aussie here somewhere? That is remote.

Alright gentleman, I'm back and ready to get back to work on Corsairs! I ended up being in LA all week, not getting home until about 2 AM Saturday morning. I may have to go back one more time this week but only for two days if I do. I will post some pics of the job we did up there when I have some, you guys may get a kick out of it. We built a pretty slick slot car track for a vintage race car collector and installed it in the warehouse where he keeps some of his full size collection. Anyway, I need to take stock of where I left off with the tailwheel drawings and I will get back to making kits right away.

Great progress on your vertical fin and rudder Danny and I hope you enjoy your vacation. See you when you get back!

In the second photo you can see I added some scrap balsa to support the 1/64"ply, had I not added the balsa, there would have been a gap below the 1/64" ply...

These pieces, which frame the trim tabs, are supplied for the elevators but not the rudder as they are easily made from 1/8 balsa scrap. (Which is called out on the plans)

I bought some german slot car track 8 years ago chad. I don't have a good basement to do that yet. I would build a nice N or HO train track first if I had a basement. Glad yer back, and I am patient on this tail. I'll probabably cut my own fuse bulkheads, but maybe I'll wait there if we can come up with something superior. I thought you might add one stringer in each quadrant on the fuse. I may have said that before..sorry if I am ever redundant. I am still waiting on a disc sander to round out the tail wheel parts if anyone's curious. I appreciate the comments from tom on not deforming the tube parts. Intuitive, but helpfull none the less. Thanks Tom.

Since there's now been a post on the CAD drawings for the fuse, and discussion on the stringers, I'll post about an idea I've been kicking around for some time. After doing the cockpit on my TF Spitfire, I found myself wishing that I could do away with much of the structure of the fuselage in the cockpit area. What I am thinking of is making that section with carbon fiber. Perhaps frame and sheet the fuselage as normal. Then cover the area to be removed around the cockpit with ultracoat. After that, lay up a couple of layers of carbon fiber that extend past the ultracoat by a few inches on both sides and then glass the entire fuse with .7 oz cloth as normal. Once set, from the inside, cut out all the balsa and ultracoat in the cockpit area, leaving a thin carbon shell which joins the front part of the fuse to the rear. Finally, add a couple of carbon small rod stringers in inconspicuous areas, or in scale locations if any. This will leave maximum room for doing a scale cockpit interior.

Any thoughts?

Scott

I had the best seat in the house at the LA Jets event on Saturday. Watching jets fly below you is quite the sight!!!
