MXS-R Ready For Shakedown!


Today was a bit of a marathon build day. I installed the engine, fuel system, electronics includingThe new electronic ignition, the old igntiion pack and reciever pack, and the reciever. I checked things out electronically, the kill switch light illuminates when the ignition switch is powered on, the receiver bound fine and all the servos seem to do what they are supposed to do (though in after thought the throttle servo needs to be reversed). I set a few limits and tweaked a few programming settings in the DX8. I essentially just renamed the old Sbach and adjusted the settings. I haven't checked the wing flap and aileron settings, instead using extra servos just to make sure the signal was right.


I installed the QuikFire fuel filter and sump, and a nice big fuel dot. I built up the fuse for the dot and the screw for the QuikFire. The tank is 380cc. I soldered the third pipe closed and its setup as a two pipe system: fill/vent and fuel-to-engine. Pic is before electronics installed.


I installed the ignition pack behind the firewall, and the reciever pack just forward of the rudder servo, right behind the Spektrum AR 7010 reciever.

The red thing is the ignition pack. In addition to the fuel lines you can see the carburetor metering vent tube ending in the orange cap. The blue control horns are the throttle linkages. You can also see the back of the Miracle switches, and the tachometer (the dark rectangle just behind the firewall at the top of the pic).

The Miracle switches and charge ports. I built up the wall f the fuse for the switch too. Repaired and reinstalled the LED for the ignition power on indicator.

Tomorrow I will pick up some two-cycle semi or synthetic oil, and gas, and see if I can get her to start!
