Scotsman, I have a VQ Macchi 205, it was powered by a Rossi .40 with hobbico mechalical retracts and had just under 10hr flight time before I retired it. It was retired because:
- Plastic Wing fillets cracked so bad from vibration they had to be removed.
- Plastic retract seround departed in flight because it was so badly cracked from vibration.
- Plastic wing tips began to crack due to vibration, I filled them with foam. The cracking stopped then parts started coming off like it was stattered auto glass.
- Plastic head rest behind pilot started to crack.
- Cowel had cracked in meny places.
- Landing gear mounts each riped out once, I replaced them with marine ply. But when they ripped out they put large holes in the bottom of the wing. PatChing required shelf paper or packing tape.
- Plastic oil cooler on bottom of wing cracked so bad it removed it's self in flight.
- Prone to flutter, caused by unanchored "Y" pushrod to elevator.

Mine sits in the burn bin awaiting sacrafice to the cloud gods. I normaly would pass it on to someone interested in warbirds in one of the clubs I belong to. But as the plastic parts started to fall off it started getting squerly, dropping wings, snapping. I don't know if this is because of the mostly missing wing tips or the wing has become very loose and can be bent almost any way I want to bend it. I'm almost tempted to remove the covering to see if it is the only thing that is holding the wing togeather. If I was pressed to rat it on a scale of 1 to 10 (10 being the best) it would round up to 3.
