Manual is assuming glow power. With gas, the tank is usually mounted near/on the CG, as the pump can easily pull fuel 3'. No more dependence on tank pressure, and no more concern about tank vs. carb heights! Welcome to gas!

As Al said, you can move the fuel tank waaaay back. I used a separate servo for choke because of the narrow cowl. Also, I strongly recommend adding a 1/8" balsa doubler to the wing saddle. The photos are pretty self explanatory.

Good luck!

+1 to all the mods above. I did them all and have had three gasers in mine---- an RCGF26, Fox .40, and now a US 41.

Anyone still flying this bird with a G38? Got one for a super cheap price and am thinking this might the best plane (of the ones I already own) to use it in.

Will probably do the electronic ignition conversion for $75 and shave some weight off too.

Thanks,
Bill S.

I have had two different RCGF 46cc gas engines and an NGH-38GF gas four stroke engine in my Sportster and those three engine flew the plane quite well. I am now moving on to a DLE 55-RA rear exhaust two stroke gas engine. I know that it will be a bit over powered but should be a lot of fun to fly.

Best wishes and good safe flying.

Got my 60 size sportster in the air yesterday, flew beautiful! Grownd handling was great, got a OS 65 AX in it and very fast, looking forward to flying it again this weekend.

Struggling to get my head wrapped around how this plane might handle with a 55-RA on the front.......

Why hold back? Put a DLE 85 on it.

Twice the power but less weight than the Fuji 34cc-B that I have on mine; though the need for an ignition battery evens that up. You won't have much cowl left and the 22" prop clearance from the ground may be tight. You should be able to pull the empennage clean off in flight, Go for it.

The GP Giant Super Sportster has a wing span of 82" and a thick air foil which is a bit on the large size for a 30 or 35 cc engine. Most 30 to 35 CC planes are 73" to 74" wing span. I previously had a 46 CC engine in this plane and it was not really over powered. Also, I am not the first person to put a DLE 55 in this airframe. There is a video on YouTube of this combination and it does seem to be hot but not crazy. I am sure this will work out just fine. I will let you know sometime later this week after the maiden flights.

Best wishes and good safe flying.

I had my maiden flights with the DLE 55RA powered GP Giant Super Sportster today. This seems to be a great combination. The airplane is not fast but does seem to have unlimited vertical. It was so impressive that several other club members are now considering similar setups. I am very happy with the plane and engine. I am using a Xoar 22x10 prop that has limited clearance but does not seem to be a problem. I am currently flying the plane without a cowl until the engine is broken in. I will not have to cut up the cowl as much for the DLE engine as I had to do for the RCGF 46cc engine.

Best wishes and good safe flying.

Hey guys it would seem I'm late to the party. I've just started to assemble my GSS, It's most defiantly building season here in Montana. I'm excited to fly this airplane as I love this type of sport plane. This thread has been quiet for awhile I do hope there are still a few following.


I have always used 30 min epoxy to make my carbon pushrods, I see most of you are using the JB weld. What are the merits of using the JB over the epoxy?

30 minute epoxy might be fine but JB Weld when it comes to carbon pushrods steel or titanium ends is the tried and true adhesive. If you've never worked with it, it's similar to 2 hour epoxy, takes awhile to setup, (sticky as heck), but really sticks to metal and carbon. You should be able to find in any good hardware store. Buying a package is worth it even to just experiment with. It's good stuff.

The overwhelming preference among all the modelers I know is the JB Weld. They all swear by it. I was using the 30-minute epoxy, and had no problems to speak of, but I wanted to see what the fuss was all about. I bought a pack of JB and on the next model I made my linkages using the JB Weld, and I could tell that it would do a better job just from using it and watching how it coated, how it adhered to the stainless end and the carbon fiber shaft. After several models, my vote is for JB Weld. Also, I found it to be neater overall and easier to clean up than the epoxy, and mixing the portions was much easier, because you can be more precise with the JB. Less waste, for sure.

One more vote here for JB Weld.

Where are my manners? Speed37, welcome to the party! I'll bet it's beautiful (and really cold) in Montana right now.

It's hard to build a GSS wrong, it really is. Most of us just pick a few of the bells and whistles that appeal to us,and make sure the GSS ends up sporting them. It's pretty much a guarantee that if you install the radio gear right, and you get the CG anywhere near right, this bird will fly true and pretty. Mine sports a 30CC gasser, and it pretty much leaps off the ground; anything 20CC's or up is plenty, to tell the truth after seeing mine in action. I have to throttle mine back a fair amount of the time with the 30CC, although it does throttle back plenty for landing, so I'm very happy with that power. I use flaperons, and it slows down to near walking speed for landings. I went with bolt-on main gear, so I had to operate on the fuse just in front of the wing. Glad I did.

Probably my weakest area is the newer batteries and power systems being used in conjunction with them. One of the guys talked me into using A123 batteries in my other plane, but I haven't really used them to any real extent yet, and I'm still learning about them. My GSS needs some fresh batteries, and to tell you the truth, I'm a little torn between using my old tried-and-true faithful NIMH packs, or going with the A123's, or even the Li-Ion setups with regulators, etc. Like so many of the crusty older modelers here, over the years I've been dragged kicking and screaming into each new technology. I remember the first time, back when I fussed because I had to send my old Futaba Gold in to have it upgraded to narrow-band. Fussed over the switch to 2.4 too, but discovered quickly that it made a big difference. I'll just have to learn about the new batteries, and then I can move on to dreading the next big changes. There's always something new and exciting to dread for me.

Thanks for the welcome!

I'll be using JB Weld from now on. Not sure how I missed it... but when I went to my suppliers website there it was "we recommend the use of JB Weld slow"

I've installed a set of HS-5645MG servos carbon pushrods and Robart hinges. I found myself short of servo wire and am waiting for that to complete the radio install. I managed to slip a piece of ply inside the fuse and epoxy it in place for a bit more tail wheel support, and installed a carbon tail wheel assembly. I'll get a few photos taken and posted this evening.

Dual A123s, Dual switches, Dual feeds to the receiver and an IBE. Come over to the Dark Side ��
Look at the NoBs site.
Washington State?
A bit too far for a drive now!
Best Regards, Jim

Did I mention that the guy who talked me into the A123's was Paul? (PGMeyer) hehehe...

It's real cheap to fly into Seattle, though, Paul. I'll let you know what I learn about the hunting here. So far, it looks very promising! This state has more cool stuff than you can shake a stick at.

Jim, I guess I missed your move to Seattle, thought you were still in San Antonio. I've been a little busy fighting cancer, only flew my GSS twice in the last 7 months. I did replace my old Futaba radio with a new Spectrum. I needed more channels and also the Bind N Fly capability. Will pick up an electric Cub in a couple of months so I have something to fly when I travel.

Single A123 with 2 output leads, 2 switches, etc. etc.

Steve,

So sorry to hear about that. I've got my fingers crossed for you here. I guess I didn't hear about it because I've been wrapped up in getting ready for this move for most of 2014. The only times I've handled my planes was to box them up to make sure they rode out the move safely. I hope it's not too long until we can BOTH get back to flying again.

Al,

The single A123 with 2 output leads, 2 switches, etc. would certainly be the simplest way to go for me, and the quickest way to get the GSS back in the air.

Yeah, I fall into the "crusty older modeler" classification.
