i have both a skymaster viperjet 2M and a new Extreme jets 1/6.75 F-16 first.. i was wondering what kind of luck people were having with the supplied Air Accessories ,like the air line ,retract valves,air line connectors, and gear door cylinders . Next .. I have a kingtech 120G and a Jetcat RX140 and i'm on the fence about what should go in what. i want the power for the f-16 but i want to keep the weight down but i want to put the 120 in the viper so i don't have to carry a lot of fuel as i want this to be a short ,grass runway ,everyday jet. so and thoughts?
