Thanks Dave! 3/4oz cloth it is!!
I'll see what I have in my stash and then get some more if I need it.

Re: My 78" Mosquito Project; She's coming along now!

Wing tubes are in!! It took a while to get the alignment right so that the phenolic outer tubes fit and were aligned. I had to enlarge the clearances of the holes here and there to make it work.

In the end, the wing tubes are in.
Now to epoxy the phenolic tube to the ribs.

Re: My 78" Mosquito Project; She's coming along now!

Spent some time going over the wing tube connections in the wing and adding doublers and more epoxy.

Before I can close up the bottom of the wing, I will first need some servo tubes to run the length of the wing to the fuse.

Finished off the night by taking some letter size paper and rolling some tubes on a carbon shaft. Used glue at the start of the roll as well as the end of the roll, and fastened it with tape. The diameter is large enough to fish several servo leads through.

They have not arrived yet. I ordered the exact same motors I have on my DC-3. 800KV. They should be here any day now.
https://www.rccanada.ca/rccforum/sho...d.php?t=205950

They worked really well and I get 10 minute(?) flights on them with 2 4S-4000's

Re: My 78" Mosquito Project; She's coming along now!

Inboard sheeting completed.

Still not quite ready for glassing.
There are gaps between the wing and nacelle that needs to be filled.


The last big hurdle before glassing the wings is the engine bay. I still don't know where or how I will be attaching the motors. I also need to make a hatch for the forward part of the nacelle. Without the motors in hand, all these problems will have to wait until the motors get here.

In the meantime, I'll start working on the the gaps between the wing/nacelles

Re: My 78" Mosquito Project; She's coming along now!

The construction is looking good.

Any comparison with the DC-3 (which I saw fly great) on projected wing loading? (the thread on the Taylorcraft crashes is on my mind).

The paper tubes for the servos wires are light... the outer third of the wing structure is exposed, in my mind, to much, much less stress than the loading on wing from root rib to just beyond the nacelles and would be tempted to sand off a bit of thickness of any remaining sheeting yet to be applied in this area.

There may be a abrupt stress point just outboard of the nacelles.... I can't tell from the photos but consider tapering span wise reinforcement from this point to several inches toward the tips.

If you want to maximize the strength of glassing consider using a laminating resin instead of waterbased on the 3/4 oz. fiberglass covering.

I've been reading of good results in posts over at rcgroups on the opacity and lightness of water based "artists" acrylic paints...... Liquitex is often touted as a high quality (high pigment percentage) brand and is available at Michael's, Staples, Walmart... dollarstore acylic lower pigment percentages but significantly cheaper and also work.

Its funny you say that. Matt and I were talking about both planes last night and
1) I expect the mozzie to come in a a bit heavier than the DC-3.
2) While the DC-3 flies like a dream, I am concerned with the stall characteristics of this Mozzie. The Dak has wings swept to the rear, while the Mozzie has wings swept to the front. Matt and I both agree it would make for some vicious tip-stall tendencies . I'm going to have to be very careful on the maiden and I think the lesson to take away from that tailorcraft thread is a) keep your speed up and b) get high up and do some stall tests so you know how it will handle when you slow down and come in for the landing.
3) The Dak has both motors canted outwards. This is a design feature from Top-Flite for engine-out when flying Nitro. When I first build the Dak, I was building it for nitro. I left all the thrust angles alone when I converted it to Electric, ,<ie; stay with the plans> and the result was a very docile and smooth flier. The Mozzie on the other hand, has 0 thrust offset. Not having plans is a real downer. I dont know what to do about the thrust offset.

For sure. I already made up my mind to go with FG cloth and resin. I think I mentioned that on one of my earlier posts

I haven't decided what to do with paint at this time. I have had pretty good success painting foam models with water based "artists" acrylic paints. For this one I will probably go with some thinned out rust paint. I've had good success with that in the past. I haven't even picked a colour scheme yet but I am leaning towards doing something that has the grey/green topside. I don't know what they had on the bottom when they did that scheme. I'll have to look around for ideas. If you got any ideas, let me know
