Its set too rich for the break in, you could turnt he LSN 1/8th just to make it easyer for yourself but no more
check the noob guide (link in my signature)
No more that 2 days max i would say mate, and that depends where its kept ... nitro fuel absorbs moisture from the air so dont be suprised if it goes "bad"
Your better off taking both hoses off (carb and exhaust) then blow down the pipe that would go to the exhaust, this should force the remaining fuel through the tank out the carb fuel pipe.
I usually do this into my fuel bottle if needed.
Sounds like its set correct mate, to test it, turn the Tx and Rx on, check everything works ok then switch the Tx off. the brakes should come on pretty quickly.
