I've got a Skybolt that's ready to be finished but I'm not sure what engine to use. I'm thinking about using a 20cc gas and add smoke. Thoughts?

I have a couple Skybolts, both with OS 61SF long stroke pattern motors. They both fly beautifully with an APC 12/8 prop. The Yellow/Black is an old GP kit built one, completely sheeted, and a lot heavier than the GP ARF. The GP ARF is at 8#, and will almost 3D. I think if I put an APC 12/10, it should hover, and do excellent aerobatics. I bought the ARF at a swap meet, as the owner ground looped it, and damaged the front end. I rebuilt it, and have been flying it ever since. It's a shame that they are now discontinued, and no parts available. Thankfully, I did buy some spare parts while they were still available. Here's a few pics of them-- Dean

Hello all!
I am currently building a Skybolt from a Great Planes Kit.
Currently, I'm running into two issues I am looking for some help on:

First, How are you all fueling your skybolts? I am considering using a Dubro E/Z fueler as my in-cowl space is quite restrivted. The other way I am considering (but won't look as tidy) is here: fuel fill valve?
Post #24 shows what I'm talking about.

Second, My cabane holters are not touching the bottom of the cockpit floor per the plans. Has anyone had this problem? If so, what was your remedy? The picture in post #16 in this thread shows the same problem I'm having: https://www.rcgroups.com/forums/show...-skybolt/page2

Thanks guys.

Since almost all my builds are scale and cowled I have been fabbing up a 3-line system to give an independent fill/defuel line that goes to a fuel dot on the side of the cowl.

Blue Regular Fuel Dot, from PSP Manufacturing, psp-170-b-n - Chief Aircraft Inc.

You can get them different colors to match so not so obvious. Just ensure it sits above the top of the tank to reduce siphoning when done filling up. The pic may be a bit difficult to see, but there is one shown in the side of the Rare Bear cowl.

Two points to add: My 3-line system is relatively easy to build and use and works perfectly. I use plastic air tubing for all my fuel lines as careful heating allows me to route it both inside and outside the tank to where required. Inside that third line runs down and to the lower left corner and never interferes with the clunk. Some simply add another clunk and that is a possibility, but I like mine better. Personal choice.

Both fittings you refer to were my go to for years and each has good and bad habits. They are quick to use, but there are internal O-rings that tend to dry up and lose perfect seal, (rebuild kits are available) and they require their own fitting on the end of your fill line that comes with the valve. The DuBro is a bit more obvious due to the protruding protective cap.

Most problems I see come from the fact those O-rings leak from both shrinkage and vibrations. Since that one is designed to fit into the carb feed line any air leak is a potential dead stick.

Not sure of your cabane problem. My original Sig Bolt was prebuilt from a kit and the Super came as an ARF.

The cabanes on mine had a gap like yours, but only maybe 1/8". I filled it in with some scrap ply and epoxy. The first one I built many years ago had a gap too as I recall, and I left it as is without any issues. If the cabanes are seated completely down to the bottom of the formers, and your wing incidences check out OK, I'd leave it. Cut some strips of ply and use that to fill in the gap between cabane and cockpit floor.

I would love to use a 3 line system with fuel dot, but I opted to use a Hayes 13oz tank with doesn't have a provision for a second decided fill/drain line. Thus, I'm left with two line options.

Cougar,
Mine is the ARF. Found it NIB at local swap meet. I have been looking around the internet for one, but could not find one.
Got this one for little less than price was new. Thinking about putting a Saito 1.20 on it which is also NIB. Got a very good deal on it years ago, but didnt have anything to put it in.

Think the 120 would be too big and heavy. The 100 swinging a MA 13/8 3-blade is perfect for mine.

I'm familiar with it, Strong as an ox, but built that way.

The ARF is relatively light so you may need to install ballast in the tail.. You may also have to mod the firewall to keep the prop spacing correct. Moving the cowl forward a bit may be an option. You just don't want to end up looking like Karl Malden.

Are you able to post some pics?

Carl Malden? you mean like with a big nose? I havent posted pics before, but now I have a smart phone. Maybe I can figure it out.
I wont be starting the build for some time. The basement is my workshop, and had trouble with water getting in. Had to tear it up and repair with French drain. remove carpet tore out dry wall to seal cracks, etc.
Will be putting man cave back together, after wife finishes remodeling upstairs. I could take pics of model as is now, just to practice. Yeah, thats the ticket.

That's the one.

I know what you mean. My build room is our old family room downstairs and is going through a major reno. New tables and everything stored away. Unfortunately that also means trying to figure out where everything is.......
