I have a cross member that mounts right above the fuel tank on my Evo50. Will the whole frame be stiffened like the CF base plate does if I mount two cross members at the bottom of the frame?

Also, what is the part number of that cross member?

Thanks,

Rudy

I use one crossmember above the tank and one below (in the forward position, not the optional lower boom support position). The crossmembers do stiffen up the frame quite a bit. Stiffening the rear part of the frame does nothing for the flight characteristics, but it does make the frames less likely to break in a crash. So far all of my frame damage has been limited to the front "legs" and the servo frame.

The part number is:

2511-024 M3x60mm Crossmember

Rudy,

The cross members will help, but they won't add nearly the stiffnness of a baseplate. The baseplate effectively puts a bottom on the "box" that is the frames. The crossmenbers have contact points to the frames only about 5mm in diameter, so the stiffness they impart is limited to the potential for those crssmembers to rock/twist about that contact area.

Thanks Leif and Dr. Ben.

Any idea where I can get the base plate for Evo 50?
