I just received my landing gear struts from RC-Castle and can confirm they are the newest v2 versions with the metal oleo housing. They look really nice and sturdy and the oleo operates much smoother over the v1's. Although I asked Raymond (RC-Castle) to send me the newest v2 version I assume from now on they are all v2 versions.
Time to do some upgrading tonight as I also received the v2 electric retracts.
A little plug for RC-Castle/Raymond: in the box I received my order in was a big Lipo charging bag labeled "gift"! Free! Thank you, Raymond!
