OK, the Tower Trainer limits the options on the front of the wing.

The fuselage is lower than the front of the wing. And it actually looks somewhat "fragile" for retrofitting.

It definitely won't accomodate hold-down pins out the front of the wing. Nothing for the pins to fit into UNLESS you build the windscreen up, and that'd look dumb. And a flat plate projecting out and forward from under the wing into the backside of the windscreen looks to be a bad idea. There wouldn't be much windscreen/fuselage to hold the plate. You could beef up the insides of the fuselage to accept the plate however. You'll have to decide if that'd work. Look inside and try to visualize beefing up the fuse..... would it work?

What's left for the front???? Bolts through the leading edge. They'd work.... cosmetically. But the wing wouldn't stand up to the bolts going thought it right there. You could plate the top of the wing just as the rear is reinforced, but the plate would have to be big and curved and creased and..... too much work.

What's left????

Hooks off the wing that'd fit over the existing dowel rods. They'd be flat plates and would have to be inserted into the wing like mutant ribs that grew out of the wing. Nope...... To be strong enough, they'd have to have been built into the wing from the gitgo.

Anybody got any other ideas?

Only one of mine seems worthwhile.

The rear of the wing already has a reinforcing plate. All you'd need to do is mentioned a post or two up. But the front........... hhhmmmmmmmmmmm........................
