I'm building a 26% scale CESSNA 210.

BTW, if I was going to make my project airworthy, what size motor would you folks recommend for this size aircraft?

Thank's in advanced.

Nice project. What will the WS and final weight be?

albeit

Hello,
Wingspan will be 115" (9' 6"). Weight still needs to be determined. I have some ideas but, I would rather get some concrete info first.

Thank's!

After much thought, I have decided to chop the empennage off to do the initial foam installation. This will ultimately make it much easier to man handle the project. Next pictures after this one will be of the foam installed.

I just revamped the Cessna 210 scratch build to 44% scale (148.9" length).

Nice start.

Are you going to make a glass fuse from your sculpted foam form?

Did this project ever get finished? Where did you get the former shapes? I am wanting to build a 33% cessna P210 Silver Eagle, and am trying to figure out where to start. I've built many kits before, but never designed my own.

ETpilot

As a T210L owner I was really interested in this thread. Then I find it is an old thread and build never completed. Oh well.

The Silver Eagle is a conversion of the P210N model. A start would be getting a 3 view of the conversion. Q&N Aircraft Modifications of Factoryville, Pennsylvania did the modification but they closed down for good. You might try the Aircraft Owners and Pilots Association 800 872-2672. They may be able to help or point you in the right direction. Fabricating the landing gear would be a project in itself. I read somewhere that a company is making a 210 gear. Good luck with the project. I will follow along if you start a build thread.

Retracts are made/sold by Radical RC. They only go up to a 12 lb aircraft though.

I need to figure out how to build a plug for a fiberglass mold, or create formers from the cross sections provided in the 3 view. I would like to design it around a MW54 turboprop.

ETpilot

Wow that MW54 turbo prop is some engine. Interesting build you are pursuing. You need to find a 3 view that has the station formers. I'm not sure if that information was provided to owners. Another way may be using picture. There are a few good pictures of the aircraft on the web. I found one that gave a perfect side view of the AC.

I found that Griggs Aircraft, Tunkhannock, PA. has taken over the SE modification. griggsaircraft.com 570 836-5757. There is also an SE forum. p210silvereagle.com. Maybe they can help.

nightflyer01

I'm glad to see that the Silver Eagle was picked up by another company. I would love to have a real one some day. I've been searching the internet for a 3d model. I think I may have found one.
I can't seem to attach it though.

If they can provide a 3D P210 model, then all you have to do is rework firewall forward for the engine. That is the main change to the airframe. BTW, I looked up that N number and it turned out to be a registered Beechcraft Bonanza.

I just looked on RCScaleBuilders and Albeit started a thread there and never finished it or got very far. On the retracts, I have had different F16 jets that have had gear that swing the same way that the Cessna series of retract planes swing their gear. I would just mount a regular retract, with my favorite being Behotec, at a 45 degree angle to the ground swinging back. The one that Radical made for the smaller one is just too complicated for the same thing with two servos operating it. The strut would be the next hurtle to accomplish.

nightflyer01

I still need to do a lot of research on this one as it's going to be twice the size of anything I've ever built before. I still don't know if I want to build it from built up balsa or make a plug and build it out of fiberglass. I want to build a scale interior and opening doors, and I feel that the formers needed would be too thick for a scale interior. I have seen one that was a kit-bashed cessna 206 that used the F16 retracts, and wile it worked the gear legs were too straight. The retract mechanism is really the least of my worries right now, I'm 90% sure I have that figured out.

Did you ever see the Great Planes C182 fixed gear ARF? Maybe it would give you ideas on the cabin framing for the wing mount. I’m sure that is what might be the concern for both the cabin and not having the wing depart in flight. GP used a wing tube for the mounting of the wings.

nightflyer01

I have the CMP knock off of it, and the formers are quite thick. If you scaled it out, the door jambs would be 4 feet thick. I would like to get my hands on the TMMY 182, but at 1500 it's too expensive.

Nightflyer01; I am sorry, but I made a mistake trying to go off of my memory. I meant the Hanger 9 Cessna 182. Here is the link:

Cessna 182 Skylane 95" ARF (HAN1875): Hangar-9

I have flown these for students with a G26 on them. Flew nice.

Here are plans for the C-182. There is one that goes up to 81 inches. I couldn't find any for just the 210. Worth purchasing to give some direction and guidance for your project?

nightflyer01

Thanks for the link. I've been looking at the plans for the 81 inch 182, as well as the plans for the 1/4 scale 152 as well. I also read through a really good build log on RC Scale builder. I'm thinking about designing the 210 around a fuselage built up from 1/4 inch lite plywood, spruce stringers and 2 layers of 1/64 lite ply sheeting then glasses. Would that be adequate or overkill for a fuselage that's 8 feet long?

ETpilot

Do a small mock up model and test your idea for the build. See how strong it would be.

Here is a side view of the SE. Something to work with and incorporate into any plans you may be using.

It would be great if you could get it into CAD and have a short kit cutter cut it for you. I think that 1/4 inch ply is a little too thick for the bulkheads, other than the firewall, and some of the wing hold down framing. Here is a picture of a Zirolli P51 that I started, but never finished due to jets. But, notice the bulkheads are actually about 1/8 in light ply, even around the tailwheel, which can take a lot of abuse. The stringers I don't remember, but around 3/32 x 1/8. I am showing you this picture to give you ideas. I built the fuselage hanging from the ceiling, rather than in a cradle. The jig frame was made first, then the bulkheads slid onto the jig. The fuse has too many curves to build in a cradle. Worked very well. I couldn't copy a Zirolli plan to show on here, but look at some of his plans. He is one of the experts in the hobby who's designs have been around for ever. With respect to the sheeting. The P-51 was to be covered with 3/32 balsa sheeting, and cut into beveled strips for curves around the fuse. I have never worked with 1/64 sheeting veneer. Thinking about sheeting a plane with it, I would think that it would be difficult, unless the bulkheads were laser cut, to have all of the bulkheads at the right level, so that there isn't a bulge or being concaved with one bulkhead between two. If that makes sense? 3/32 sheeting offers more forgiveness, greater sanding and shaping ability, won't blister trying to laminate the two veneer plywood going around difficult fuselage curves. Large plane are normally fiber glassed with 3/4 oz fiber glass. I don't use West epoxy, but Zap's Finishing resin reduced. But, that is a long way away from where you are now.

nightflyer01

Thanks for the link. That Mustang looks great, hopefully you'll finish it some day. I definitely need to start drawing this up in CAD. 1/8 ply is probably good for most of the bulkhead I will probably just use1/4 for the firewall and the formers at the cabin where the wing mounts as well as where the landing gear mounts.
