Sketer-40 V3

I ran by Hobby Lobby yesterday and they had some tristock but it was 60/60/60 instead of the 90/45/45 that we typically get. Might have been why it wasn't in the kit.

I was a little worried but then the plans say it gives plenty of throw and so it makes more sense to use.

Busy time of year for me, which seems like a constant cause it'll be that way for the next 9 months, but I hope to start spending some time in the evenings working on this and be laying down some Ultracote before too long.

is easy to lay a pen on table, run surface along it, making centerline- just hold pen at the right angle to hit center. then plane/sand bevel. quick, easy, and a lot cheaper than buying tristock.

i never tristock hingelines, since like 15 years ago. i've also made several tristock cutters, make 2 pieces ply spaced with 1/4 balsa. square 1/4 hole in center. tap a blade in at an angle from corner to corner of hole, tack with thin c.a. works ok, but you got to use soft balsa.

you can also use a piece of ply several inches long with 2 pieces tristock glued to a centerline on it, creating a jig that will hold 1/4" square at a diamond angle. clamp to scroll saw almost touching blade, hold balsa down with one hand, feed slowly with other. that works well, even with hard stuff. if you use lke 1/2" tristock you can make fairly large stuff. 1" no problem.

side note, i use a jig like that with a hole drilled in centerline as a drill jig for hinge points. drill slow, it'll center hole exactly on the edge of the beveled surface.

Yeah I thought about making my own just using 1/4" square balsa because that's how hingelines were always done in the past. I decided to give it a try and for $5 and some change, I'd give it a go.

This hobby takes money and some people are all into FrSky because it's so much cheaper than Futaba or Spektrum for example and the programming becomes a side hobby. For me I'd rather spend my time building and flying than dicking around with software so I spend more on my radios.

But I still look at those FrSky systems every now and again and consider getting one.

Yeah I'm not putting OpenTX down. There's a guy who has competed in the old TOC and stuff flying at our club and he uses an FrSky with OpenTX but he's also an engineer :lol:

I would normally put this in my the Build thread except that anyone else that still has these might want the resources I guess.

I ran out of 1/8x1/4 balsa and Hobby Lobby didn't have any either. So I took some 1/8x3/8 and sanded it close to the 1/8x1/4.

Not as easy as it seemed but I got it glued on. I'm hoping to work on sanding the trailing edge of wing next and work on gluing on the tristock to the control surfaces. Probably wouldn't hurt to write down some notes and come up with a list of stuff to do so I don't miss anything.

And my apologies for the shit lighting in the garage.

I'll look into doing something. Space is at a premium unfortunately.

Ben,dont stay in the dark,even the led screw in bulbs can put out a lot of light,a 60,or even 100 watt led will brighten up that room. One 40 watt strip,4ft will clear things up. I had 4ft old type 40 watt,put in 4 new 40watt led strips,bright,dont look up. Try one led strip,on a drop cord,hang it over table,you say wow.

I think I figured out why the Skeeter 40 was designed to glue on tristock for the hinges.

I missed that note on the plans and had just glued on some 1/4x1/4" balsa and man it was tough to get the bevels sanded.

I started by marking the middle of the balsa and then I was just going to go back to the other piece of 1/4" balsa that makes up the aileron. I only did one aileron tonight and I'll do the other one tomorrow. The problem I believe was how light the structure is.

And that's not to knock the desing in any way. It's a 40" electric profile so you have to keep it light.

I did glue on the tristock to the rudder. I used Gorilla Wood Glue for that and taped the piece down while the glue cures.

LOL, still looking into lights.

My wife and I are potentially moving to a different house this year so I'm trying to be judicious.

Second aileron is beveled and it was also a pain.

My transmitter is on its way to Futaba to get checked out for good measure and it'll be 10-12 weeks. I might have to drink some of the FySky/OpenTX koolaid and give it a go so I can do some flying between now and then.

As such I also hit up a nearby lake and caught some whitebass today.

Nice progress on the skeeter Ben :rockon:

Just curious why those bevels are giving you trouble. With 130 grit sand paper it shouldn’t take more than 10 minutes per side. Is there any way possible it could be bass would instead of balsa? Only reason I ask is because if it is, it would make hinging very difficult down the road.

No worries. The structure is just built bery light and so trying to sand nice and even without breaking apart the structure makes for very tedious work.
