We have had the T34 kits here for about 6 months now. We have had no issues at all with the standard retracts but, most of our airfields are sealed. The two formers under the cockpit floor are perforated for easy removal. They are only there to align the fuselage while it is being jigged. All in all a good model with good flying characteristics and good value for money. Well done CMPro! TF
