And I do love to build!

Rick,

Once you do the first wing your going to say to yourself " What the hell was all the fuss"!!

Even if you screw up on the cut you can always fill it in with balsa and do some sanding.

Trust me, We all felt the same way until we did the first one!! LOL

Re: JTec Radiowave MX2 2.8m Build log

Building has slowed down for some reason but I continue to chip away at the MX2. The first few pictures are a bit out of order but they show the layout of the outer and inner ailerons as well as the 1/4" by 1/8 spruce sticks that I used for the trailing edge surfaces.

The last four pictures are closer to where I am now and show a little trick that my friend Alan (building the same plane over on RCCanucks) told me. When you pre-drill and shape the hinge blocks it is critical to get the blocks glued down right on the centre line. This is not always easy to do because the wood glue allows the two parts to slide around a bit and its not always easy to tape and centre the blocks onto the wing cores correctly. Alan suggested using building pins as a temporary fixture while the tape is going on and while the glue dries. Simple idea but really simplifies the process of accurately centering the hinge blocks.

Hi Gordon:
Will you have this bird at the Vernon Scale meet this year?
Thanks,
Mark.

Re: JTec Radiowave MX2 2.8m Build log

I am at a similar point as Gordon, I got some hinge edges glues up yesterday and I will post up on RCCanucks soon!

Funny thing about the pin idea, the best ideas usually are a result of something not going as well as it could/should have and I have been using this pinning strategy for other things and have recently adopted into building this plane.

Sharing ideas is one of the great things about build threads and friends, Gordon has been super at hints & tips and sharing his knowledge with me

Re: JTec Radiowave MX2 2.8m Build log

Hi Gordon,

Here is something I have been using for years for gluing in hinges. I use Titebond . I wash all the hinges off in warm soapy water and dry. Then melt a little vaseline in a pie tin, fold the hinge and dip it in to the joint. I use a glue gun to put glue in the hinge line. If you find the hinge is a little tight going in just give it another squirt of glue, It acts as a lubricant.

If you get a little overage on the glue it can be wiped up with a damp paper towel.

I have NEVER had a hinge pull out. I actually got that info from the instructions on a Robart hinge package many years ago. Its a lot easier that using epoxy and its easier to control than gorilla glue.

Re: JTec Radiowave MX2 2.8m Build log

Al Young: thanks for the hinge pin trick. I have been using Gorilla glue with these types of hinges but I think I will try LePage "100% Glue" (similar to Titebond) for the hinge pins along with the canopy on this bird.

Thanks Braden, with a kit like this it's really pretty simple woodwork. Hopefully threads like this will inspire other guys to give building a try!

The wings are basically finished other than a little final filling and sanding (and covering). Not really sure that I have enough aileron deflection but I guess I'll have to make do

Gordon,

A little more sanding I bet you can get 90 degrees!! YIKES!!!!! I think I want to see the roll rate the first time you do one!! OMG!!!

Ya, its a bit much but I built in this amount of deflection for resale value only. I don't 3D so the maximum throw for me is around 20 degrees on the ailerons.
