Quick question guys, I'm working my way through the build- but how did you glue the spar in? I have the wings glued on so I assume im supposed to force some glue into the thin groove on the base of the wings?

Did you guys use hot glue? Or maybe some gorilla glue?

I followed the instructions lol

basically, glue the spar into one wing before you glue the wing to the fuselage.

put that wing on the fuselage, then put the other wing onto the spar and fuselage at the same time.

I used 5 minute epoxy for the spar in the wing slits, I wanted a strong connection.

Ooops guess I missed that!!

Gorilla glue or super glue? Hmmmmmm :s

[iPeel]

Uhu Por if you have it is best, but if you had to pick one of those two you suggested then definitely Gorilla glue.

[Billy_boy_2010]

Just filled it with gorilla glue. With a bit of luck it will seep around the spar a bit. It's not going to be an aerobatic plane anyway.

Feel like a complete idiot. Was watching wheeler dealers of all things! That little orange fella who keeps saying tarrra put me off :D

If it's the strip (flat) spar version you may want to use diagonally inserted pins to hold the spar down in the slot to stop the gorilla glue from pushing the spar out during expansion.

It's a normal round spar fortunately :)

If I sand it down properly it should be ok hopefully! Feel such a lemon!

 Mine has been delivered!!!!  ;D Glued a couple of bits up after getting in from work, before running out of foam glue..... :opps: In my excitement I forgot to add some to my order..... A tube of uhu por is now inbound 1st class.

And another one falcon evo in the build. Good fun this build goes together really well.

Went with the eco setup from flyingwings

I only used Por on the spar for mine and used hot glue on everything else, including joining the wings to the wood.

  I'm a big fan of hotglue, I even use it to hold pieces of wood together to turn on my lathe, so I know how strong the bond can be but I would worry about getting the joint thin enough and having the time to get enough on say the wing end before it cooled and thickened/hardened where I had started applying it. How do you go about it? Or is it just a case that the foam is such a good insulator it just gives a bit more time?

To glue the wings I actually put it on the wooden part and offer up the wing half. The glue stays plenty hot enough for enough time to apply the glue, get the joint together and adjust the leading edge so it meets the cheek guide perfectly. Hot glue stays hot for ages, at least mine does probably because my gun is knackered!

Por is great for gluing foam to foam and the spars in because it gives enough to move with the foam so the joint is never stressed, so I still always use that on the spar joint but and I think I use Gorilla glue on the bit where the spar runs across the centre section to fill the void, everything else is hot glue and it means I can build a Falcon in about 2 hours. As I'm now on my 5th Falcon I've had plenty of practise!

 Thanks iPeel, I took your advice and went for the hotglue option, glad to say my wings are now on solidly and in the right place!  :)

Just got back from this evening's flying... I fecking love this wing... Vector suits it perfectly.

I'm pulling around 15 amps on full throttle, thats with the 1400kv turnigy motor and an APC 8x4 prop... such a brilliant glider too.
