Estes Scissor Wing Transport Build, Part 8, Rear Stabilizer
The front of the stabilizer is glued on the rear of the tube, centered and even with the end. There are small center tic marks at the front and back of the stab.
The inside angle is too tight to apply and smooth out fillets.
Glue was pushed in on both sides to reinforce the joint.
Glue was also added to the front of the joint and smoothed out.
The instructions have you attach the elevator and tape hinges now. TIP: Wait until paint is applied so the tape hinges will adhere better.
The tube mount spacer (lug and standoff) is glued down the center line of the stabilizer.
The tube standoffs are glued on either side of the lug and standoff.
On the right, notice the low corner of the "slant" end is even with the back edge of the flat stabilizer. This slant end stops the raised elevator at ejection.
I don't know how stuff the sticker sheet material is on the new version of the kit, but I do recall in the old version the instructions had you to folding the elevator up and down several times to put a crease the hinge at the joint - otherwise the hinge may be too stiff for the elastic thread to pull up the elevator sufficiently. If I recall it was a similar story with the Gyroc.
ReplyDeleteHi Naoto,
DeleteIn the end , the older sticker didn't stick very well. Even though I attached the elevator afterwards it didn't require any creasing of the hinge to raise it.
Hrm... I'd never had an adhesion problem with the tape hinges -- just had a problem with the stiffness. Perhaps part of the problem I had with the stiffness may have been the coat of paint? Nowadays I'd likely use the hinge tape used on R/C planes, which seems to be more pliable than the paper tape. As an added plus the adhesive seems to have on that stuff seems to have much more grip.
DeleteOne of the other things I'll probably have to consider when rebuilding the Scissor Wing Transport, Gyroc with similar elastic to actuate a surface -- modifications to make it easier to replace the elastic.
Hi Naoto,
DeleteIt's easy to change out the elastic on the Scissor Wing. ERockets has come out with a new version of the Gyroc and you can now change out the elastic.
Aside from pre-creasing the hinge material, another idea might be to make sure there is a very slight gap (no more than a thickness of a sheet of paper) between the stabilizer and elevator - this would likely help to loosen up the joint.
