Building a SPAD Canard

A friend named the plane Runard. My name is Rudy. I like the Runard name. Thanks, Tim. I designed this plane about 2 years ago. It has a 48 inch wing span and is powered by an OS 46FX engine. Flies like a dream. Here are the building instructions, 5 drawings, and two photos. The photos show the vertical stabilizers larger than on the drawings. This is because I recently added the profile Coroplast fuselage shown in the photos and drawings. The vertical stabs can be reduced in area as shown on the drawings. Questions are welcomed.

Impressive design and certainly one to put on the "will build sometime even if it takes years" list. I can't print right now and can't quite read the instructions, where's the fuel tank located ?

Hi Cris...The main tank is mounted on top of the 1 inch square aluminum fuselage, with the back of th tank against the LE of the main wing. A small header tank locates next to the engine.

Chris, once you open the instructions to enlarge them , or the drawings or even the photos, you have to again click the lower right corner to enlarge them again. Let me know if this works for you. I have a 17 inch flat screen and they show up very well. It was a chore to size everything so it is legible after being ground thru the Internet.

Thanks for an other set of awesome Spad plans.....Going to be busy building this winter.
Thanks again.

Mr Greenspeed, Did you ever build the Canard? If so, how does it fly! Can either of you (Villa or GreenSpeed) post a picture of the underside (bottom) of the aircraft. A picture is worth a few hundred written words. Thanks and the build has started. I will be sending notes and pictures to Villa as the build progresses. This will be a slow build as I don't plan on flying it until spring 2007. North Dakota is in for a cold winter I think this year as the temp never got to 32F today at all and forcast is for colder this week with snow in a few days. The blood needs time to thin out before I will stand in one place and freeze my feet off. I will get a flight in each month but maybe one or two a month for the next 4 months. Retirement coming next year so I'll be able to run south for a couple weeks and get some flying in. Thanks in advance for the pictures if you get the chance.

Pilot12. There are 2-3 ways of calculating the CG on a Canard. Since the results differ a little, and I did not understand some of the reasoning, I made up my own calculation. The maiden flight was a high tension event. As with any CG placement, start nose heavy and make adjustments as performance and experience dictates. You can search for my method on the SPAD forum by searching for canard as a subject, and villa as the author. Be glad to answer any question you have, but I hate searching. The search engine here gives me poor results. Just keep digging.

I've said this before and it bears saying again. When in doubt, cut it out, of stiff paper. Cut out a scale overhead planeform of your ship, fold it slightly in the center to give it some stability and if necesary, apply a thin dowel stick to the centerline and add weight where needed to get the airplane to glide nicely. The plane shouldn't pump, and it shouldn't dive to the ground. Instead your looking for a nice flat glide. That's the forward CG of your airplane.

Hi riond. You asked for some photos of the bottom side of my Canard. Here they are. The photos show the Canard in a crashed condition. I pulled a stupid stunt, lost orientation, and spun into the ground inverted, on a blacktop parking lot. I need a new wing. You can still see the broken prop. I dropped from about 100 feet and there is almost no damage. The wing spar is broken so I'm making a new wing. I don't remember now if the canard wing needs replacing. As I mentioned earlier, the profile fuselage gives the two rudders too much control (authority). I will reduce the profile area by ending the front of the profile about even with the TE of the canard wing. I will also reduce the rudder movement (authority.) I hope this crash does not turn you off building the Canard. Riond, this morning I also answered two of your PM messages to me. Hope to hear from you on that. Don't you or others be afraid of the drawings. Not everyone can understand them or needs to understand them. If you need more photos just ask for them. Ask any drawing questions you have.

Villa,
I'm not sure if I responded directly to your PM or just in the forum. I just got my shipment of new coro and then slipped on the ice in front of my place. Broke 2 ribs. (My battle buddy called me a klutz.) Live in ND all my life, you would think I would know better. Oh well.
I plan on working on the Canard build and hopefully have it ready to fly in the spring after the snow is gone. I'll probably just build a couple of them as long as I'm cutting one, may as well cut two.
Are you planning on making it to the Spad Fest 2007? My plan is, if I go with my battle buddy, we would bring a couple combat planes and I thought a Canard, Coro Cub, Lawn Mower, and maybe a Spadet [>:]with. Just have to see how winter works out. The more wind, the more building time. [sm=spinnyeyes.gif]

Hi riond. I had seen your message earlier. That is terrible about the two brocken ribs. I cracked one rib in my Army days on a parachute jump. It was a bad experience. I will not be at the Spad Fest 2007. PM me and post here with any questions on any of my planes.

I have just had a read through this thread and downloaded photos and instructions. I'm looking for something unusual to fly in the wind over here which just doesn't want to die; no good for light weight balsa close-to-scale, which is my main passion.
I'll get my son involved as he is quite quick with correx. (he built, set up and flew his first correx model, a QHOR, in an afternoon during a club build get-together). I'm trying to finish off a scale SE5a which is taking forever!

Hello franc. Glad to hear you may build my Canard. Here are two flight reports:

I just reduced the area of the fuselage on my Canard to make it less dangerouse in knife edge. I also changed the muffler to a PITS style so the exhaust is more in the direction of the rear of the plane. No oil mess at all.

Is there anything special you have to do with the fuel tank for a pusher? My plane is having problems with the pusher engine. I have the tank facing forward and about a foot of fuel tubing coming back to the engine. Could the tubing to long? sometimes it wont even start, but when it dose the fuel always backs up in idle, then when I go to WOT it dies. I have my low end leaned out so I dont think thats the problem.

Hi Pilots12
In the photo above your last comment you will see I have a 2 once fuel tank very close to the engine. The main tank is in front of the main wing. Connect muffler pressure to the main tank pressure connection. Connect main tank out to small tank pressure connection. Small tank out connects to needle valve. I have zero fuel problems.
