Default RE: Hughes H-1 Racer for Q-40

ORIGINAL: pylonracer2

I would like to buy one, let me know what the wait time is and how much it would cost to ship to south florida.

Thanks
Charlie
Charlie,

The Hughes H-1 fuselage is not joined, and does not have a wing saddle or stab saddle molded in. You have to figure out where you want the wing and cut out the saddle. Then join the fuselage halves.

I did this as a prototype, and the cost for a fuselage and foam wing cores is $50 shipped in the US.

I've been relatively inactive in R/C for the past 4-5 months, but I'm getting back in gear and can get you one pretty quick. In a week or two. I have one fuselage on hand at the moment. You can PayPal me at [email protected]

It was very impressive that you posted this whole project. I am starting something similar and all of your info lets me know that it's more than I have time for right now. I think I will create a very nice fuselage and then send it off to get it done by someone like you who knows what he's doing. Thanks again for all of the info, Erik,

Thanks. This project was actually an enlightenment of how fast a fuselage mold can be made. And there are techniques for doing it even faster and cheaper. The pink foam worked out ok, but there are things I'm going to do differently next time I do a pink foam plug.

Stan Douglas, the NMRPA webmaster, has done some work with a material called Hydrocal or something close to that. There is a video on making plugs and molds that have some cool techniques for molding parts quickly.

If you're looking for another Q-40, I now have molds for several Q-40 planss: Duane Gall/Ed Smith's Stinger, Jerry Small's Swee' Pea, Dan Kane's Rivets, and Dan's Miss Foxy Lady. The Stinger molds are temporarily out of service, but I expect to have them ready to use in a couple of week. I'm getting ready to make my first Rivets this weekend. It has matching cheek cowls and would be a good candidate for an electric installation.

I'm doing a set or tail molds for Dave Norman (and myself) at the moment. I'm posting the entire process here in the Q500 section and on a couple of other forums. Let me know if you need any molds made.

Way back in 2003, I did a plug and mold construction article on making a plug using pink foam. I originally posted it on RCUniverse, and the full thread can be found there at Hughes H-1 Racer for Q-40. I have posted part of the thread at Hughes H-1 Racer - Making the molds. You can see some photos of the real airplane in the last link.

I designed this plane so that I could use any wing and stab on it. It does not have a stab saddle or a wing saddle. But the way I did the wing saddle area, it is very easy to add some balsa and plywood doublers and mount the wing Quickie style.

Since there was no wing saddle, there was no opening through which to join the halves. The intention was that the builder would select the wing location, cut out a saddle area, and then join the halves. It's not terribly hard to do. Just tape it together, untape the tail and glue it with some thickened epoxy. Then after that has cured, use some CA to tack the sides together. Then 1" 9 ounce fiberglass tape can be placed on the seams through the wing saddle.

I'm getting ready to test some Q-40 wing designs and test some pitch moments. So I joined up a couple of halfs. It wasn't too bad, but I've gotten pretty good at doing wet lapped seams while fuselages are still wet. I try to do as little manipulation of the lap as possible, because I tend to create more bubbles than I fix. I though, what the heck, let's try to do a Hughes joined in the mold, even though I only get one shot at getting it together.

My wife is now helping me make fuselages. It takes me 3-4 hours to do one by myself and I am drained after I finish. With her help, we can now do one in 1.5-2 hours.

We made a Hughes on Sunday. I cooked it in my hot box for about 16 hours. I used WEST 105/209 hardener so we would have as much working time as we needed.

I took the fuselage out this morning. The lapped seams are not perfect, but I'm pretty sure they are still better than taped seams. There are some minor bubbles along the seam line in places, but they are easily filled.

My goal with this plane was to be able to use it as a test mule for wings and stabs. But it should make a fine Q-40 Sport plane. The missing wing saddle allows for playing with different wings and moments. But it should not be plenty easy to mount the wing. It could even be built as a one piece with a hatch.

The nose of the plane is plenty big for electric outrunner motors. The E-Flite 46 BL Outrunner will definitely fit, and I think the 60 BL will also.

Now that we can produce the fuselage joined in the mold, I'm going to increase the price just a little, and offer kits with plans and foam cores for $60. You have your choice of an SD6060 or MH-24 airfoil. The 6060 is a little more forgiving, but some people think the MH-24 is faster. It is the airfoil used on the Polecat.

If you are going to build for Q-40 Sport, I will bundle a JETT Q-40 mount for the Thunder Tiger Pro 40 for an additional $20.
