Had one 7 years ago. Flew great with a xyz 50cc gas eng. plenty of power no bad habits put guy wires or struts on the rudder and hoz stab. The shake bad. Landing gear is 3/16 piano wire so gentle landings are required. Nice plane for the money. RON

How loud is a DLE 35RA with stock muffler?

The nice thing about the 35RA in this installation is it's compact dimensions - due to the fact it comes with rear exhaust. If you get the 30, you'll need an aftermarket wrap around Pitts type to keep from hacking the cowl up to bad. The popular one there is by Jtec, which is 90 bucks or so.

When you add the 90 bucks to the price of the 30, the value of the 35RA becomes more apparent?

I was never much for doing builds through the winter, probably because winter in Maine requires lots of work just to get through it, and because Texas just doesn't HAVE winter. Here in the Seattle area, we have winters that have just the right balance. I think I'm finally going to enjoy a winter build, and I'm set up to work. I have a couple of planes all planned for builds this winter; first is to finish my electric-modified GP Super Stearman, next comes the General Hobby 74" Raven, and I have a small Decathlon tucked away if there's time, also an electric modification.

My Syssa comes with a Pitts muffler, so I don't know what to recommend for a DLE, but a number of the guys in this thread have used the DLE 30 and other brands, and they told us what they used so it would fit into the GSS cowl. Sounds like you're going to have a good build, sdstick.

Looking at the folks browsing the thread. Hey, rivnut13!

I was in the marketplace, and I found this wraparound muffler for the DLE 30. I thought it might be something of interest.

On the GSS they (the muffler in market place and ebay) do stick out of the cowl on the port side (left)

Looks like to me the DLE 35RA is going to be the best choice for the GSS.

On my Syssa, the muffler is tucked directly behind the engine, which has rear exhaust, and the Pitts configuration fits beautifully inside the GSS cowl with room to spare. The Syssa is an awesome running engine, strong running and dependable, but for a while the folks at Syssa Aircraft had some difficulties keeping up with things, and for a period of time I was withholding my recommendation of them. However, since they've just added an additional service enter to handle the demand, I can recommend them again. The Syssa engines cost a little more, but they come with the Pitts muffler (and the muffler comes set up to accept smoke fittings) and rear exhaust, which makes a nice installation. You can see photos of my Syssa engine install in my GSS in my posts.

Yeah, the DLE35RA is very similar to my Syssa configuration. I've heard from a few of the guys that it fits nicely.

I want to say hi and thank you to everyone that has contributed to this thread. A short background on my self I started out flying CL and moved to rc my first plane was a little tex with a os 30 great motor not so great plane especially for a beginner. I have just returned to flying after a 20 yr break purchased a apprentice 3 months ago and really love the plane what a great trainer. Figured I would stick with e power do to being quick and easy also cost of nitro fuel is way up. The club I joined has a lot of people flying big gassers and I really felt out place. Well 3 weeks ago a guy made me an offer I could not refuse. A GP Giant Sportster with a dle-30 for 300 ready to fly I just had to bind my radio to it. Weekend before last I got 2 flights in and wow what a great plane. I am going to swap control rods to carbon fiber add flying wires to tail and move landing gear to fuse. It already has robart hinges. Figures since I got this great plane it has done nothing but rain hear in NC first real rain in 2 months really hoping I will get a chance this weekend but not looking good Bummer.

Hi xraysrt6,

Yes, you've got Hurricane /Storm Joaquin bearing down on you! Lotsa fun in the rain!

Sounds like you got a great deal on your GSS. The mods you have planned all sound like items that should be addressed. The flying wires on the tail are a must, especially under the stab. It's great that it already has the Robart hinges; that's a BIG plus for you. I agree with the carbon fiber linkages too. With the flying wires combined with the linkages, that'll be a real solid finished product. Some busy-work for you while you wait for the rain to pass by!

Agreed. Sounds like a good set-up.

I've got a 34cc and the flying wires on the empennage . . . but I kind of like the gear on the wings. Wider stance and my second glow model was a Contender 60 (which I still fly) and that has similar. I think it looks better than the fuselage mounted gear. Personal preference.



Didn't go with carbon but I definately recommend ball-link attachments.

I ordered my big stik gear and hardware today. I am going to use aluminum oval tubing instead of flying wires on tail it is very light and I used it on a cub years ago and even after multiple crashes the tail was still in one piece. I will post pics when I get them made and installed. I am going crazy wanting to fly the weather here has been perfect for months so I guess it had to get crappy sometime just sucks that it picked now. Even after the rain stops our field is in a flood plain so it might be underwater might have to think about floats HAHA.

Curious - why didn't you just go with the Big Stik? I have one of those as well (26cc Zenoah) and it's as good or better than the Sportster as far as flight qualities.

Xray,
Where do you get oval aluminum tubing and what size?

I also think the gear in the wings looks so much better.

Thanks,
Bill S.

Not to step on X-ray, but Tower Hobbies or most hobby stores with a K&B Rack will have various sizes of streamline tubing. (1/4" through 1/2")

http://www3.towerhobbies.com/cgi-bin...?&I=LXR852&P=7

I used the tail-wire bases and wires that were for a 1.20 size GP Ultimate. Nice in that the tension is easy to adjust with an allen wrench

Charlie, Charlie, Charlie......

NO WAY the big stick flies better than the GSS. Nor does it look anywhere near as pretty as the GSS. Few planes do.

But I'll give you this: The Big Stik CAN do some pretty wild things if you set it up for crow, etc.

You really don't need the gear any wider than the Big Stik gear. Lots of guys use the GP Super Stearman gear, and they have no problems at all, and the Stearman gear is 4 inches NARROWER than the Big Stik gear. Also, I think the tall gear looks awesome on the GSS.

I totally agree about the Stearman gear. Here's a pic of mine.

hear are some pics of my tail mod and a pic of the aluminum streamline tubing. I got it at the lsf. I painted it to match pretty happy with how it came out. Should get my big stick landing gear by tue and be ready to fly by sat. I am also going to set up flaperons. I know that there are a lot of opinions on CG but I was wanting a middle of the road set up I am not a aggressive flier at this time so how far back should I set the cg since the landing gear move will force me to rebalance.

I got to re-read the 2846 posts. I think it's 5/8" behind where Great Planes suggests. But check me on this. I know there was some heated discussion on this, but I think the general consensus agreed a little back helped with landing, and made the plane a little more loose. But please do research this and make your own decision.

Note that with rigid struts you only need them on the bottom (they offer compression and elastic resistance unlike wire).

I agree about the rigid structure but I also like the additional strength it gives the vertical stabilizer and with a dle 30 additional air resistance is not an issue. On the cg I see where people have gone as much as 1 inch so I will probably go with the 5/8 suggestion thanks Tom. I got the flaperons setup and set them at -35 on my DX6i.
