The door is on the wrong side.

The Klass Kote was very nice. I'd don't have anything to compare to but it was easy to work with, even using my cheapy Harbor Freight touch up gun. I'll probably invest in a better gun before its time to paint my next build. Thanks for the heads up with the gear.

That was too easy!

I have a Sata Minijet paint gun, it is really nice and basically the last gun I will ever need to buy. Almost too nice to put paint in!

I clean it religiously after painting, looks good as new after all these years.

I'm planning a Ikon N'wst Monocoupe 90 next, I'll have to look at the Sata before paint time with that one. The HF gun did a fine job. The fan was pretty good though there were a few irregularities in it that showed up a little on the mist coat but on a wetter coat it caused no problems. I had to be careful about he paint flow and fan adjustment screws as they kept moving. The worst part about painting for me was cleaning the gun.

I had to make a set of bungee covers for a friend's Cub so I figured I'd make a "Photo Tutorial" of the process for those in need.

First, make a pattern. Just make sure to account for the expansion of the gear as it articulates on those less than perfect landing. You also need to account for the bungee pins inherent to the gear itself.

Second, fold the ends inwards to make a pocket for the zip tie. I use zip ties on each end to pull the bungee closed, simple, easy to replace, and work perfect.

Third, iron the folded cloth to make sewing easier. I use a tiny anount of water on the cloth and my covering iron for this process. The sewing does not go to the edge, this will be apparent why later.

Fourth, once both ends are sewn turn the cover 90 degrees and sew it into a tube. Keep all the seams to the outside for now.

Once that is done trim down the excess and cut a 45 degree bevel on the ends adjacent the seam. This will give you a gap in the material for the zip tie to enter and exit from. Make sure not to cut your sewing or it will unravel as time goes on.

Lastly, turn the cover right-side-out hiding all the seams. I use my little finger for this.

Add zip ties to the ends, install, and enjoy having your o-rings / rubber bands last for months instead of a week.

Very nice SDP! I may have to make a set myself. I had purchased a set from Cub Man but darned if I can find them! I looked at them once, set them aside and then like so many things, they just disappeared into thin air!

Thanks for the tutorial! One question though; what kind of fabric and where did you get it? (Whoops! That was two! My bad.)

Pilot has to be in the back seat in a J-3 Cub........unless the upper added wing tanks changed the CG maybe....

Default L-4 Sig conversion

So back on page 112 I posted a pic of my cub with all the holes in the side. Thats the way I got it. I finally got that layer of holey plywood off the side! My question is...(insert drum roll here) since I want to do an L-4 and the wing is already done as a two piece, I see in the thread how to attach the formers to the top of the cabin to open up the cabin and create the modified two piece wing. Since I don't have any plans, should I get Cubman's L-4 plans? Is that the best way to go? Also, what is the deal with scale ailerons? how do they differ from what comes with the Sig kit? Do Cubman's L-4 plans come with the scale aileron plans too? (guess thats directed at Cubman but will take an answer from anyone).

I guess the root ribs that I need will be in Cubman's plans...if not I'm sure someone here can help me out with the outline of the ribs, or can we just order the ribs from Sig? Why is the sky blue? Is there really a Santa Claus...ok ok I'm done.

Thanks in advance!

Dave

wasn't there someone doing an L-4 back around page 65ish, what happened to him?

As far as the scale ailerons question, I'd PM cubman and ask him. I went with the stock ones per the Sig plans as my plane is just going to be fun fly and not all to scale. As far as the question about the 2-piece wing - I don't fully understand your question. Are you talking about modifying yours so the center wing section is part of the fuse and each wing plugs into the side?

I have the ribs from the center section that I didn't use still in the box, if it would help I could trace one and scan it to PDF and send it.

It will require some pretty extensive re-engineering. I think you can see how I did mine if you go back in the thread but basically I used 1/4" ply to make a new root rib that was 1 piece with the top of the windows. It allowed me to eliminate the the mid cabin former. I added extra music wire up the front corner posts of the windshield that are countersunk down into the new ply root ribs. They're shown on page 87 and 88 of this thread.

Neddy,
Now that you pointed it out I see how you incorporated it with the window...nice work. Since mine is built already I of course want to attach the root rib as strong as possible but don't want to take apart and rebuild any more than I have to. I like the idea of more music wire. I think I could groove something in to work. I just realized the root rib is exposed on one of the wings so I won't need an outline but thank you for offering. But if you have an outline for the door, I would be more than happy to accept an outline for that!

I've been busy and haven't gotten the last few thing buttoned up on the Cub yet. The only big thing left is installing the windshield - I think its the part of the build I've been looking least forward to. I did buy thinner plastic from Balsa USA to do the windshield with. Once I get it installed all I have left are a few odds/ends.

Make sure you do one out of card stock/poster board first. It makes the final fitting so much easier. But then you probably knew that.

I used the plastic that came with the kit. It is a bit tough to bend, but I did it! Good luck.

When you maiden, are you going to have it videoed? I hope so, I always enjoy watching someones creation take to the air for the first time!

Take care,
David

I'll try to see about getting some video of the maiden, whenever it happens. This has been a much slower build than I had first expected, I think I'm going on 15 months now. My wife and I are expecting our first child so alot of my spare time has been taken up fixing up the baby's room lately.

Is anyone flying this with a 120 4 stroke? Would it be enough?

That depends on what you define as "enough".

The first one I saw flying was about 1984 with an original OS FT120 twin. From the way it performed, IMO, that was more than enough.

However, when I built mine, the clipped wing version, I installed an OS 1.08 FSR as I decided that more than enough would not be a problem. That was considerably more than adequate and the largest single cylinder glow 2 stoke engine available at the time..

If I do another, which may happen, for several reasons, I'd look for something about the size and output of an OS 1.60 FX.
