I used the Eflite 120 electric retracts for my 83% Turbinator. I have used them on other 60 size warbirds and the Hangar9 B-25. I have been real pleased with them. The struts are Robart but Io don't know which ones. I used the HK brakes and wheels. Those have also worked really well, especially for $50.
The gear and brakes is one of the reasons I choose the 83%. I was thinking budget for my first jet in case I stuffed it.
