Don't wake a Tiger until you've factored the teeth



You have not read the BEX build log properly

1. Do NOT use such thin Ailerons. They will flutter. Your Ailerons, Tail feathers incl. rudder, stabs, elevator should be 4 mm reinforced with bamboo skewers
2. The spar should be joined at the dihedral angle before assembling the wing.

I know you are young, and don't want to discourage you, but a bit of care at this stage will save a lot of grief and frustration later. I know, because at your age I would do the same, and suffered Cheesy

Oh.. then I guess I have gone through some other thread....but the autor was BEX...
I glued the top edge to the bottom edge and tried a glide test of just a wing half... glides well...
Does the par need to be joined with a wooden dihedral brace or the same method that was used to make the spar may be applied?

I will measure the coro again and tell whether its 3mm or 4mm :-)

Dear topalle

I don't see your ratios to be correct!!! just have a check with the image i have put.

Its not that the planes other than the recommended ratios do not fly but better to go with the proven design first.
