You see rhysduk, you got plenty GOOD advice comming FOR FREE!!
Rocky is on the button!!.....a lazy elevator means too much nose weight!
Take some out to get the cg 10mm back and throw again....
Bare with as rhysduk, we'll get you flying this machine soon!

After watching the clip a few times, I think taking out nose weight will improve the performance plenty!! I can see it stalling from pulling on the elevator. I also think the wind was a tad light. But next time for sure!!......she will fly!!

Cheers guys, there's hope yet then!
In order for me to build a new wing, I'd have to destroy the current wing (1. I have no spar spar material unless made from 4mm correx) but wouldn't this mean i'd have to make a new fuselage as the wing profile would be slightly different resulting in a new wing seat on the fuselage being required?

I don't think there's much wind planned for this weekend so testing will have to wait. boohoo

Thanks for all the help!

I had to destroy my 1st wing to get the spar out. It turned out to be a good move as it enabled me to see test for weak points by twisting and pulling etc, and how strong the glue was, which I've always wanted to test. It gave me much more confidence in my build strength, allowed me to see errors to be corrected, and showed me what I could get away with in flight.
You could just make new doubler sections for the wing profile, like the ones you installed a few pages back. Cut out the old ones just above the seam. For the new doubler section, make the new inside layer (vertical flutes) slightly taller than the flush outside layer (horizontal flutes) to have a good spliced join. Don't go nuts with the hot glue though.
For the wing:
*Remember to get the flutes perpendicular to the fold line when cutting the wings out.
*Score well, and use a jig (check out argo-2s post #1480 for an easy fix).
*Double/triple/quadruple check the aileron set up and the rear centre tabs and layers (also pays to do this before cutting).
Good luck on your mission sir.

Awesome clip Bakkie!
Amazing how cool it looks flying in the first person with the other Migs buzzing around!
FYI, those that were'nt at the event, this footage was from the day before the start. The conditions started GOOD and just got BETTER!

Amazing vid! By the looks of it the mig7 is a popular choice. I'm still surprised it hasn't caught on big time outside of SA, electric or slope. Sure there's the odd group and a couple of randoms, but not the popularity this amazingly diverse plane deserves. I guess the rep SPADs have of being heavy, ugly, hard to glue and tricky to set up is a hard one to shake. One guy at the field thought it was factory made until he was standing right next to it!

Yes JMSR!
The same here!
I have built with balsa,.....plenty, but find corro the best for our slope flying antics!
People here also frown on corro cause its "cheap"
I think above all though.......it's not as easy (in the beginning), to build (understand), corro! ........... IMHO!

After doing some digging (read as tidying) I found 4 wings I had cut out when doing the originals... And IIRC the flutes are the correct way (perpendicular to the fold line)....
