RE: MVVS 21's
In 1/12 scale combat I ran mine with 2% nitro only. The black muffler with added mousse can aftermuffler takes away all high pitched noise without power loss. When properly setup, fastest or second fastest starter on the grid. (electric fliers with catapults are faster)
What is a proper setup?
Three line tank.
One line for filling (has filter), plugged in flight
felt clunk pickup, straight to carb. (or sinter clunk)
one line from muffler to tank. needs to end neitherin bottom nor top of muffler, so it will not pick up oil.
Clean fuel needle bar!!!!!!! This is the item most forget!!!! Clean muffler connection!
I start and clear the engines throat, warm it up a little, check carb setting for the day.
put the glow plug cap back on, switch of the power box.
Putthe plane on support, nose up 15°, throttle 1/3rd open. Then wait for the rest of the pilots to go through their routines.
On start, run to the plane, switch onpower box, tap the E-starter on the spinner, unplug glow cap, grasp plane just behind the engine, applythrottle and low hand shove-off while engine responds to throttle! Works every time, average Le Mans start time from whistle to on the wing about 7 seconds.
I can tell, the other pilots did not like my liitle MVVS at all.
