RE: ESM Dornier DO 335
Well...the brake kit and electronic air valve etc doesnt cost $400. The entire brake system is like $260 with air tank, brakes, air line, fill valve, electronic proportional actuating valve and tubing. However, I had to buy the Robart 4.5" wheels because the ESM wheels I have arent designed to work with brakes. No one else makes brakes for 4.5" size wheels that I am aware of except Glennis and those would be ridiculously expensive. I was informed of another place that makes brakes on RCG, but they only go up to a 4" wheel and this plane takes a 4.5 and could fit a 4.75 without mods.
So...rather then trying to retro fit something that may not work anyhow, I just coughed up the dough and got what will work.
