Install gas engine rc plane

Choose the GT9 Pro for your next project and you won't be disappointed. Please note: All RC model gas-powered engines require the user to properly set up, tune, and maintain the engine in order to achieve consistent peak performance. You will need to break-in the engine initially, then perform routine maintenance including cleaning the engine, lubricating its seals and moving parts, and adjusting the fuel mixture and valves as necessary. This is considered the normal responsibility of owning and operating an RC gas engine.

Simple but very important! Of course, we must deliver the fuel to the carburetor. Modern gasoline engines use a pumping carburetor that literally sucks fuel through the line coming from the tank. Though we can seldom run the supply line straight to the carb, with a little thought we can find a path that eliminates substantial deviations up, down or sideways.

Crap Trap Yes, that is the name of the device made by Sullivan Products I use to filter the fuel one last time before it gets to the carb. This is a very simple filter that can be easily fit to most planes. I also like this filter because it is virtually bulletproof and if the lines are secured to its barbs, will never leak.

Lots of folks will add another Crap Trap to the fill line coming from their gas can through which they fill the tank in the plane. This is a cheap way to add a little more protection to prevent getting junk in the system.

The orifices in a carburetor are very small which means that tiny pieces of debris can plug it up. Adding a couple filters to your filling and flight fuel systems is not overkill or paranoia.

The good news is that nearly all modern fuel tanks are very capable if assembled and maintained correctly. The solution for the changing attitude was remarkably simple, put a weighted end on the pickup line inside the tank.

The weight of the clunk keeps the pickup line that feeds the carburetor in the fuel throughout rolls and flying inverted. The fact that I can do tumbles and other near-instant attitude changes with my more aerobatic planes shows me that the weighted clunk idea works.

The important thing about assembling the weighted pickup line is to be sure that it is not long enough for the weighted end to rub against the opposite end of the tank. It can become stuck as the planes attitude changes and hold that line up out of the fuel.

This still lets me use nearly all the fuel in the tank but insures the free movement of the clunk. Another important clunk-related point is what happens during a hard landing or crash.

The weight of the clunk under these forces can fold the fuel line forward and make it nearly impossible for it to feed fuel to the engine. Even the failsafe works. SC and S1 would trip when main power was turned on. Nothing would trigger with SC and S2. I place the relay between the main switch load to the hot side of the amp relay for controller. Now i want to kill ground the lawn mower engine coil ground with a relay.

I wave another relay and a optical kill relay. It has the RX plug a power in and out. The RX has it own trans 5v power supply. Been staring at the power lead thinking how to wire it to keep the grnd circuit open for run then close it via TX to kill the engine.

Ive also thinking of playing with a relay that keeps the circuit open with power or closes with power loss. This is a little off but i do fly drones. I have another relay and a Rcexl optical kill relay. Designed by Katsoulis-IT. Skip to content. Rc kill switch for gas engines. Dimitrios Katsoulis. February 13,
