Hey young boy, does an ELECTRIC ducted fan that hits 300mph in a dive, 250 straight and level, and stays above 200 in verticle flight sound like enough? If you thought yours screamed, listen to this! If you want to make it louder and even faster, just add more cells in the battery to the cells in series. I also added a bit more elevon athority, for that nice flare on landing. Notice how the inflight screen shot says 271mph. Airport: SKyHawks Field - Cedar Rapids Iowa
