I was actually looking for a reason to buy a scroll saw and oscillating sander.

I did this build with an x-acto blade I did use a jigsaw for the ply parts at times though lol I was wanting the scroll saw myself but just never got there as a matter of fact I'm still wanting that scroll saw LOL hopefully this will be the year. yes a 50cc would be extremely cool

Well I started reworking the Tweplica plans posted for the 20cc gas engine and it is going a bit slower than anticipated. So far I have changed the design to have removable wing panels and utilizing a carbon wing tube. I also added a few more ribs. Once I have thumbnailed everything to where I am satisfied I will redraw them neatly.

I have not yet decided if I am going to utilize 2 elevator servos or use a bolt on tail and only 1 servo?????

BTW, I am also itching to reduce the plans so I can do an electric version about the size of the Twist 480. So many things not enough time.

Hey Greg Yes too many projects to want to do and not anywhere enough time to do them, I believe the 150 sized is designed with a wing tube and 2 wing panels maybe someone will chime in here with some measurements or any help you may need.

Tweplica 30cc

I am planning on building this plane this winter. Wingspan comes out to about 72" and looks to be a good size for my DLE 30. Has anyone built or started to build a airframe of this size? Any ideas re welcome.

I think the 58 will be a perfect size for the 20cc. It looks like it can be done with little modifications, but bringing the wing ribs closer together wouldn't hurt. I'm sure on the 30cc size you will be adding a few extra wing ribs.

Yes, at 72" the ribs are about 8.5" apart. I would bring that down to 5 or 6"

Yuppers i am doing the 58" version and I have altered the wing plan to include a few more ribs, carbon tube wing joiner and I plan on utilizing 3/32" balsa for wing sheeting as well. My gut is telling me to go with split elevators utilizing 2 servos, one on each side. Haven't finnessed the fuselage yet.

I was looking at the 58" wing, might just leave the spacing but am going to beef up the material. I'm debating on if the tail is going to be 1/4" thick or 3/8". I think the 1/4" will be plenty. I was also debating on the tube for the wing but considering the fuselage is about the same length as the wing, I'm not going to bother.

By going with a wing tube you'll be strengthing the fuse.

A wing tube really won't help the fuselage unless you were planning on making two wing halves that bolt to either side of the plane. Some kits may have a two piece wing that still just bolts on to the plane.

Great to see activity here and plans for the bigger the builds in progress please feel free to post the pics as you go. I'd love to see them.

AJ I do believe 1/4 inch would be plenty for the tail feathers but you might want to check out how the CG is going to be after you strap the 20CC on there as you do want this bird a little on the tail heavy side once your familiar with it. so 3/8 might just be the way to go unless your trying to keep the weight down considerably. but I think 1/4 will keep you very happy all together.

Greg Split elevators isn't a bad Idea at all

JSChoen very cool also, I think you may want to go with a Balsa Ply frame for the fuse or at least Ply sticks for the doublers I built the 40 sized with all balsa to keep weight down and it held up just fine, I used birch ply for the Firewall, formers, wing hold down plate and landing gear mount but ply construction for the frame on a 30cc I think is in order here. I'm not sure you need to as I only built the small version so maybe someone who has owned a 60 or 150 might have better advice here.

I plan to use 3/32 on wing ribs and sheeting. 3/8 on all tail surfaces. lite ply on the fuse. I would like to mount the wings on a tube but fear I could not drill the necessary holes in the wing ribs and fuse accurately
