Status: offline 		I don't think the gear placement is that far off - looking at the 3-view on vansaircraft.com, the mounting and rake are about correct - I think that the leg ont he gear on the fullscale 6 is typically wider at the fuse and tapers down to the wheel.

I think the particular angle that we see makes it look like the gear doesn't trail much, but I think the centerline of the wheel is just behind the trailing edge of the wing, and the mounting point of the leg is a couple of inches forward of the leading edge.

Status: offline 		Chris: You are right. The photo doesn't show the rake-back as much as it is. But if the centerline of the wheel is at the leading edge of the wing, which it is, you know it has to be raked back the correct amount.

Status: offline 		Jim - are you going to vac form your own canopy? If so, you planning on a single long canopy, or maybe a 2 piece setup? I am designing a removable top hatch into mine for access inside the fuse, and was thinking about splitting the canopy at the bar behind the pilot's head.

Also - is that a Quart of Pennzoil that's going to be pulling fuel cell duty?

Status: offline 		Chris: Yes I am going to try and vacuum form my own canopy. It will be in two pieces, split over the top like where there is a roll bar. I made my entry doors into the radio system on the sides, using hidden hinges. When it is covered, you will never know the doors are there. To make the canopy, will need to build a mold - then a furnace, and forms to hold the plastic while heating and forming. It will be a BIG job.

Yes - that is a Pennzoil can doing the duty of a fuel tank. I use that in ALL my planes. Direct one-piece line from the felt filter inside the tank to the carb. Two other lines - one to fill - one to vent. NO fittings required. Simple, cheap, and better than any tank on the market.

Status: offline 		Nice work. It really looks good. I was bitten by the RV bug before the RC one by a coworker that built a quickbuild RV6, his kit number was the 53rd quickbuild. I too would like to build a full scale RV 8. What are you going to power it with?

Engine not selected yet. Somewhere in 80 to 100 cc class. That's all I know at this time.

Glad you like. You will see it fly one day. Am busy now converting all my models to the new Spektrum DX-7 systems. This one will fly on DX-7 also.

Status: offline 		Here's another brief up-date. The fuselage has been completed and covered with Ceconite. The covering has been given three coats of nitrate dope, thinned 50/50 with laquer thinner. Then it has been primed with one coat of white latex paint before applying any color coats. The top side will be orange, and the bottom will be yellow. Sidewalls will be white.

The next step will be to install wiring to the ailerons/flaps, and other controls. Install batteries and switches also. Then do the fairings around the landing gears, and make molds for the wheel pants. It all takes time, so will do another up-date in about two weeks.

Status: offline 		I have a lot more work done on the airplane - radio installed, and the canopy mold is made. The wheels are on, and fiberglass wheel pants were made to fit over 5 1/2 inch wheels. I am waiting for two large 4 x 8 ft. plastic sheets to arrive, one to be .031" thick, and the other .040" to form the canopy. The engine has also been purchased - have settled on the Zenoah GT-80 which I believe will fly this model realistically. Will post some more photos in a couple of days when I get a chance. Once the engine is fastened to the firewall, I will then proceed to build the cowl, and it will be all downhill from there.

Selleri: Thanks for bringing this old post forward, and thanks for keeping me up-dated regarding my good friends in Iceland. Sorry about the Tomahawk misfortune.

Status: offline 		Here is an up-date on the progress for the RV-6. First of all, the mold for the canopy is finished, made up of cardboard, foam blocks, and lots of balsa. It is finished with several coats of clear butyrate dope - I used that because I have lots of it just waiting to be used in some manner.

The plastic is here - one sheet of .031 and one sheet of .040" thickness. Sheets are 4' x 8' - so I have plenty to work with.

I did some testing using some old plastic, and I find that I can drape the plastic over the form, and using an extra pair of hands fitted with two pairs of gloves, the plastic can be formed over the mold using a heat gun. One guy works the gun while the other is constantly forming the plastic to the mold. It's a slow process, but I believe it will be a lot simpler than trying to vacuum form. I will do it in two pieces - the windshield and the top.

The mold is 27" in circumference and 27" long - so doing it in one piece would require a sheet of plastic about 30" square. Doing it in two pieces will require additional square inches.

Following are photos of the mold by itself, and setting on the fuselage to give an idea of what the plane will look like with a canopy in place. It doesn't fit tight because of some beefing up I had to do on the underside of the mold.

Status: offline 		As you can see by the previous photos, I have the cowl under construction also. There is a Zenoah GT-80 bolted to the firewall, and the cowl framework is being constructed around it using balsa. When I get it to the point of near finish, I will cover the front section of the fuselage nose just ahead of the landing gear with waxed paper, and then fiberglass the whole cowl so that the cowl joint will be just forward of the landing gear - and not where it now appears to be. When the fiberglassing is done, then I will balance the airplane. If it comes in nose-heavy, then most of the balsa cowl framework will be removed. Should it come in tail-heavy, however, then the cowl will remain as built - keeping the balsa framewok intact. I have a fiberglass arrowshaft in place for the CG, so that the model can be hung from the ceiling to do the balancing. I will post pictures of this process when the time comes.

The radio and servos are installed, and this shows in a photo of the cabin with the
