if it has thickness much more than paper the corner opposite the hinge has to be removed. just dont chop into where the hinge will go. as in this diagram. 3mm depron has more than enough thickness

I've been painting the foam before covering. I use just a light dusting of Pactra R/C paint .

just had a maiden flight outside with my 2 cell, BL version. and it went quite well. i was surprised as i thought it might be too heavy to fly as it was designed for one cell. totally different to my 2s parkzone sukhoi although same weight and power system., as its really floaty and slow and just wants to go into a hover by default. the hover is surprisingly easily controlled even though im totally new to hovering a plane. i thought it was much more difficult to do lol! its quite well behaved and all controls work ok, even though i used a short throw brick and aileron servo. with power off it just stops level in mid air and floats down neutrally even without much input, so must have got the weight balance about right. little chance of crash damaging it. the rudder control is awesome; it turns very tightly. although the motors got some power, its size (more area than weight) dulls it alot compared to the suk. it still shoots vertical, but theres not alot of point really as unlike the sukhoi, its totally rubbish blasting around forward or vertically as you cant maintain it in level flight easily a high speed due to its sensitive flat wing shape, but thats probably true of most floaty profiles. one problem is my wing strengthening struts keep coming unglued during flight but hopefully ive fixed them securly now. i can see im going to have fun with this.

edit. weighed it today. AUW 48 grams

Maidened mine today and it flies great. So much better than the 4-site.

I need to put mine together. I'm a little nervous about the build, but these things look so cool!

It's a simple build. I cut all the parts out first. I have a metal sheet that I lay on my bench which I tape the covering to pulling it tight and getting all the wrinkles out. Then I take each piece and dust it with 3m spray and then lay it on to covering and running my fingers back and forth making sure there is good adhesion. Then start building and adding electronics and carbon fiber. Took me about two hours all said and done

Wow...no way I'll get it done that quick the first time!

Did you hinge the control surfaces?

I used some small pieces of hinge tape to hold everything in place while I was placing the covering on

Every says these fly much better than the 4-site but how do they compare to the UMX Extra 300? (my gut guess says they should be very similar in slow flight abilities and agility)

Got a chance to fly a little more in the shop yesterday. It's a 3-car bay and I'm not a wizard on the sticks by any means. The plane is great in a harrier. Knife edge has a little coupling but I mixed it out. Rudder turns are very predictable. I really like everything about it so far. I'm already thinking about the 2nd one I will build. It will probably be brushless and will try to get it a little lighter.
Also, the horns that Brian supplied are great. Makes the ailerons move much faster than on the 4-site.
