i hate test stands for one reason, they have about 1/100 less rotating friction that's caused by the propeller vs. the baldes on a heli,

i had had a .32 os live for 15 gallons before losing copression and here's how i broke it in,


threw the engine into the heli, then ran it boggin rich, you want to ge the engine to a bogg then 1..2..3.. second then you want it to respond,...

take it for a 1-2 inch hovor and do that for about a minute then land and let it sit for a tank idleing, then from there slowly increase the hovering time till you do a full tank, then run rich from there and fly slow and non agressive,

the engine should be cold enough where you can grab it with no discomfort.
