Sorry to hear of your iccedent. Hope the plane is ok..

I started at the factory settings, ie. What the manual says for both needles. Started the engine let it warm up at a high idle for about 2min. Open the throttle and put the tacho on it. check the reading and shut the motor down. Wind the high needle in an 1/8th of a turn and re-check rpms. Do this until the rpms peak and then back of 200-300 rpms. Next is the low needle. once the high end is set start the engine and let it idle for 30 sec. Then quickly open the throttle. If the motor sags it is lean and you need to open the low needle. If it coughs or burbles it is rich and you need to close the low end. Alway adjust the needle in small increments. The factory low setting should be close. All you are looking for to start with is a smooth transition. If it doesn't sag or cough leave it. Go fly the model and at these setting the motor should have a slight burble in the midrange. This is good for break in. You don't want to go to lean. fly 5-10 flights on the intial settings then every 2nd to 3rd flight after that tweak the both needles 1/16th of a turn. Be sure to check the transition before flying. The midrange burble should slowy disappear and the engine should begin to feel stronger. Once the burble is gone recheck the rpms and peak the high needle for max rpms and lean the low end until it motor sags on transition. Then richen the low end until it transitions smotthly again. Then go fly until you have burned at least 10 litres of fuel (it took me about 10L of fuel just to tune out the burble) then switch to synthetic oil retune as previously discribed and go fly.

I am running a 20oz tank in the ultimate and get about 20min of flight time set a timer for ten min land and check the fuel load and work out from there how long you could fly for. Personally I fly for 10min as that is when I start to loose concerntration.
