One of my main gear door hinge broke before flight..... this is the second time so i decided to remove both doors. I am about to install the new metal hinge replacment from BVM..... they are exactly the same but in metal.
I also find out the airplane flies exactly the same with or without main gear doors. My main gear and doors works perfect with the supplied rams, airlines etc. I only use a very large bottle for air from Dreamworks and the same for the brakes.
I do charge to 110PSI my main gear.

The more I fly the Viper the more a like it! it is a superb flying plane.
