FLYING
Before flying your Hadron be certain to follow all of the instructions accompanying your radio control system for charging the
transmitter batteries and performing a range check.
Also be certain to periodically inspect the hook-and-loop straps retaining the battery to make sure they hold securely. Replace
the straps with new material as necessary. Frequently inspect the motor wires for signs of wear or chafing. If necessary,
protect the wires with additional shrink tubing or suitable tape.
The Hadron is an easy flyer—you could take it out right now and get the hang of it pretty quickly, but even experienced pilots will
benefit from these basic flight notes:
3S vs 4S
The Hadron is perfectly content flying on either a 3S or 4S battery—provided of course you use the correct propeller. On 4S
with the 5.0 x 5.0 propeller the motor draws about 40A static (about 30A average in-flight). On 3S with the 6.0 x 5.0 propeller the
motor draws about 33A static (about 21A average in-flight). If you like to fly pedal to the metal you’ll find the Hadron is faster on
4S, but still flies slowly well and performs flat spins spectacularly. If you prefer to get used to your Hadron before going all-out,
consider starting out on 3S where the Hadron will be slower (but definitely not slow at full-throttle!) and slightly lighter for even
easier launches and landings. The reduced current draw on 3S also results in longer flight times.
Set a Flight Timer
If flying your Hadron on 3S, set your flight timer to 3-1/2 minutes.
If flying on 4S set your timer to 3 minutes. Those are about the
minimum flight times flying full-throttle with the recommended
2200mAh batteries. Check your battery voltage and recharge
capacity when you land and adjust your timer accordingly—
treating your batteries conservatively, resting, unloaded voltage
after a flight should be no less than 3.7V/cell and recharge
capacity (the amount of capacity that goes back into your battery
indicating how much you used) should be no more than 1760mAh
(80% of 2200mAh). Flying “normally,” your flight time may end up
closer to 6 minutes on 3S and 5 minutes on 4S (or even longer),
but it all depends on your flying style and throttle usage, so start
conservatively and adjust your timer as required so as not to
over-capacity discharge your batteries.
Launching
Launching the Hadron is a cinch. It’s so easy that you can do it yourself; however, if it makes you feel better, you can always have
someone else launch it on its first flight. It’s best to launch the Hadron on low rates and at full throttle. Simply hold it by the finger
grips on the bottom of the fuselage, advance the throttle to full and throw it upward into the wind at a 10-15° angle. Be extremely
careful to keep your throwing hand away from the propeller. The best way to do that is good follow- through after the throw; let
your arm arc downward immediately after you release the Hadron. If you decide to do the first launch by yourself, we recommend
that you dial in five to seven clicks of up trim just to make sure it climbs. However, that’s only for the first flight; once the Hadron
is trimmed for level flight, it will climb out rapidly regardless of launch angle.
