Performed section 46, installing both main and nose landing gear. I purchased Matco wheels and brakes, the WHL 600XLT kit, plus a Matco nose wheel and axle. This upgrade is significant with better nose wheel and installation, but also much more powerful brakes (6 pistons vs 2 stock). I bought retread tires from Wilkerson Tires in Virginia; a lot more rubber and MUCH lower price than a new set. I also completed the FF1 drawing except for mounting the engine. I bought stainless steel heater valves from ACS for two reasons; they provide better sealing protection to the firewall in the event of a fire, but they also have a higher quality flapper that is an improvement over the stock valves. Worth the money.
