F14 ....

The elevator linkage needs to have a slot using dremel, to make no excuse for slippage in flight.

The ABS frame is epoxied and pressed to the fuselage. I lost one of the 18mm M2 bolt for securing the hinge. I fix that by using a M3 bolt instead and I find that gives even less slop. The product is a perfect swing wing with slight anhedral (wing tip pointing down). This can gurantee the wing from forming dehedral on wing loading.
