I am surprised how close in size the 50cc H9/Carden Yak and the 85cc AW Yak are. I either have a very big 50cc ar a small 33%

Thanks Micheal! I ordered a pair of skis last night! It came to $76 Cdn after conversion. When I get them I'll install them and we'll go do some flying.

Ya, the H9 / Carden Yak is a very big plane for it's size and the 85cc AW is a little on the small size. Put them side by side and they'll look similar.

Re: 35% Carden Extra 330S - Build Thread

Well, got the vert stab / rudder all finished and was going to go back to the hatch when I saw my cowl sitting there. I couldn't resist making it look like an Extra (finally), so I spent the afternoon mounting the cowl.

The fiberglass parts are amazing quality. Only minor sanding will be required to have it ready for paint (I'm actually going to try to Monokote the fiberglass parts before I have them painted)


It took a bit of time to tweak it perfectly, but here's the steps to get it to the picture:

** Mount the L brackets to the upper plywood cowl former and the (2) lower cowl formers.
** Use the plans and position the formers on the motorbox and attach to the motorbox with the L-Brackets.
** Tape the two peices of the cowl together and sand the plywood formers until the cowl is perfectly flush with the fuse.
** Once everthing fits perfectly, glue the cowl formers onto the fiberglass with Goop... remember to leave 1/8" of gap between the fiberglass cowl and fuselage to give it that trademark Carden look.

Over the next week, I'll open up the front and sand all the fiberglass edges so that they perfect fit. More pictures to follow once the Goop dries.

Re: 35% Carden Extra 330S - Build Thread

This morning I unbolted the cowl from the motorbox after the GOOP had dried. The bond turned out perfect and the plywood cowl stiffeners are now bonded in for good.

When I get back into the project Tuesday night, I`ll sand the edges of the fiberglass and post some more pictures.

Re: 35% Carden Extra 330S - Build Thread

I have been following this thread with interest as I'm building a Carden Extra 260.

Some Questions.

You mentioned the 1/8 in gap in the cowl could you explain that?

You also used Goop to glue Plywood to the fiberglass. What kind of Goop?

Hey Mike! Post some pictures here of your Carden 260 when you get a chance!

If you look on the sideview plans of your Carden, you`ll notice that there is an air gap between the back of the cowl and front of the fuselage (when completed, the Carden`s look like the cowl is floating on the front of the plane). It`s nothing special, but just means you have to take your time setting up the plywood cowl stiffeners in the right place and sanding the back edge of the fiberglass cowl so that this gap is constant around the perimeter IMO, doing this air gap properly is one of the differences between a good build and a great build!

In terms of the GOOP, just go to Canadian Tire in the Automotive section (near the sealants) and look for └utomotive GOOP in clear colour. It is amazing stuff for sticking down canopies/plastics and gluing things such as the ply-cowl joints, because it never gets brittle and can resist any sort of vibration. I was a sceptic of this stuff at first, but I now swear by it!

Cheers

Trev

Re: 35% Carden Extra 330S - Build Thread

Well, this week has been a little hectic, but I managed to sneak in a few hours on the hatch/canopy.

I followed the plans and used 1/4" balsa stock for the back plate and the spruce stringers. I recessed these peices 1/32" in from the fuse so that when the plastic canopy is glued on, everything will come together flush. A ton of work, but I think it will pay off!

The front dowel pins are in so I'm following the plans and my Edge 540 and went with (4) 4-40 screws and blind nuts.

Re: 35% Carden Extra 330S - Build Thread

I also got the hatch sheeted, dash installed and sanded the Carden dash panel flush. You'll also notice on the top sheeting of the hatch, I sanded in a recess so that the plastic would be flush.

Re: 35% Carden Extra 330S - Build Thread

Now for the trickiest part of the build so far (at least for me!!). I logged 4 hours on the plastic canopy getting it trimmed just perfectly so that everything is free of waves and flush to the fuse sides.

It was a pain in the $%&, but it came out so nice...
