<div></div><div>So I am somewhat familiar with how an RC tank sets up. Currently, in my trainer it is an open engine set up, plenty of access. I disconnect the pressure line and the fuel line to the carburetor, then fill the tank threw the fuel line over spilling into a small external overflow tank, (waste no fuel) then hook it all back up again and fly, repeat over and over. So my question is soon I will have more sophisticated set up’s that will not allow or at least be very cumbersome to do it this way. I have seen some fuel line fillers that are Y's, and you just fill threw it. Being most tanks only has three inlets, one for carb, one for pressure and one for overflow. So what is the preferred way to set up a tank?</div><div></div><div>Thanks</div><div></div><div>TB</div>
If they are available to you, I recommend the SLEC range of square tanks.
The pipes for pressure and overflow are moulded in, so don't leak. There is a facility for sight-glass connection for quantity indication (although I've only ever used it once). The filler and pressure pipes enter the tank at the very top so if you stand your plane on its nose slightly inverted when de-fuelling, you get every last drop of fuel out of the tank. The clunk pipe is turned from brass and has a rounded tip to help prevent the clunk tube from getting fractures. It is a hex headed screw fitting, the same size as a glow plug, so can be fitted with the glowplug spanner. An O-ring seals it to pressure.
All-in-all, well thought through and high quality.
