I have picked up quite a few kits cheap on eBay recently including a Hawker Hart, Bristol Bulldog, Gloster Gladiator Mk I, Heinkel HE51, Fiat CR42, Boeing Peashooter, PZL 24, Dornier DO17M, JU 52, and Bf110C.
The Hart will be reserved for some Egyptian Pulp stuff I am doing and all the German aircraft will be multi-purpose. However I do plan to make the rest specific to ECW3 - starting with the Bulldog and the Gladiator.
Any advice on flying stands would be appreciated - most aircraft I have have fixed undercarriage so it would be nice to be able to use them both "in the air" and on the ground.
