The majority of the radio system was now in, leaving just the engine and tank to be fitted. The tank is a 94 oz 'Jet-Tech' Kevlar fuel cell, so with that amount of fuel, a substantial tank mount was required. The Moki 400 was refitted and hooked up to its throttle and choke servos plus ignition module. One additional item I was requested to fit was a small 'Piezo' buzzer that sounds as soon as the ignition is turned on... a simple safety device to tell you the engine is live and a reminder to turn if off after a flight. The Moki 400 is fitted with a standard 5 into 1 collector ring at the rear of the engine and there is no exhaust system supplied. Not wanting to spoil the appearance of the cowl, I had to have a scale functional exhaust system, but rather than go for the six pipes per side as per scale, looking at the diameter of the short exit pipes from the collector, one pipe per side would be ample, with the remaining five being dummies.
