I understand that the DH5-20 is just a two-pitch prop but I haven't quite worked out how to use it properly. I do the normal start-up with the pitch set fine and wait for the temps to get into the right range, but when I throttle up for take off, she starts to run really rough. If I throttle back it smooths out but then I don't have enough thrust for takeoff.
So I'm not quite clear on proper procedures using the DH5-20.
Edit; After some testing, I find that although the real Hurricane only had two mixture settings, full rich and full lean (weak), since I have my mixture on a slider I can lean it just a little and it cures the rough running on take-off. I still need to keep the radiator open all the time or she overheats real fast, even at cruise settings.
