Combat Planes.
« on: December 01, 2016, 02:57:52 PM »
Thinking of getting into some slow speed combat. More chance of minor damage , rather than demolish one another.
 Many of you have seen my Fokker DR1 Triplane and this would be a good candidate. Rolly is going to build one, after flying mine. No use having two DR1s fighting , so I'm building a Sopwith Triplane.
 These are made from foam underflooring 1/2 in. and 3/4 in. thick, depending on where you buy it from, Home Depot or Lowes.
 I'll try to do a step by step. I got a three view of the Sopwith and blew it up to get 30 in. wingspan. I trace the patters to posterboard in case I need to make more parts. ;D The parts are cut out of the foam with the smaller Olfa knife. As easy as cutting out a cardboard plane.
 Just doing the hinges for the ailerons. Made from Drywall course tape.
Will add pics ASAP
  Here's a pic of the Sopwith Tripe at least.
 Have to fix my camera. Bummer.

Well, you guys better look out for Herman the German! He has survived 6 crashes and is ready to rise to the sky again!

Since Reg and Rolly have the DR1 , I will need help to get more Sopwiths. :(
 Here is some of the construction. 1 pic shows the parts cut out. The rest show how to hinge the ails.
 After I cut the ails from the wing, you can see where I cut the roughly 45 deg. bevel at the bottom.
 Then I cut slits in the plastic covering where I want the hinges to go. The hinges would not be strong enough just glued to the plastic. I fold back the plastic from the foam. The drywall tape shown is from Home Depot. Its cut to fit the cutouts in the foam. Then hotglued to the foam. Be quick as you have to put the plastic that's folded back, put back down over the hotglue while it's still hot. A popsicle stick or the likes is easier on the fingers.
 I also found "with use" with this type of hinge was not strong enough using the threads themselves. So I covered the cross threads with hotglue as well and they are standing up very well. They are stronger than hotglue hinges by themselves as well so it's a plus, plus thing.

Don't have plans but if you're really interested I can make some posterboard patterns for the DR1 or the Sopwith.
 I just do a Google search and blow it up to get the 30 in. wingspan. Ails are 3 in. wide and the tail surfaces are about 20% bigger.
Next few days I'll put up more assembly pics.
 Get your Olfa knife out Dwayne. ;D

Sounds easy enough, I'll give it a try.  8)

 Just some pics of the bum end being put together. I found the nylon flat hinges work well here as the bottom of the rudder being dragged through the grass gets lots of abuse.
 The hinges are held in with foam safe brand named " Foam to Foam" glue. Hotglue dries too fast in this instance.
 So you see I'm not always a hotglue fan. ;D
 I also put a touch of oil or grease at the hinge point just so any glue won't get into it and lock it up when I'm putting it together.

A few more pics of the progress on the Sopwith Tripe.
 Once I get it assembled I'll show the progress on the electronics. and landing gear.

Looking good Gord. What size motor, prop and speed controller are you using?

Motor is BP Cheetah from LE 2217-07. ESC is 30 amp. 1900ma batt Prop will be around 9 or 10 in.
If you do decide to build one I'll give you a hand on here with advice and such.

Thanks Gord, I do believe I have a 2217 on hand and I also forgot about servos, 9 gram?

Yep. The HXT 900s.
 If you don't have the foam yet, get the 3/4 in. sheets from Home Depot they're straighter than the 1/2 in. ones from Lowes. They're at the opposite end of the store, against the back wall.

Darn I didn't read this, I bought the 1/2 inch stuff from Lowes oh well I think it should still work.

Finally got the Sopwith Tripe finished. Did a couple of test flights before I put the detail finish on it. Flies much like the Dr1 tripe
  Oops !! forgot something ! The pilot. Be right back!! :o
