FLYING

Before ﬂ ying 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 chaﬁ ng. If necessary,

protect the wires with additional shrink tubing or suitable tape.

The Hadron is an easy ﬂ yer—you could take it out right now and get the hang of it pretty quickly, but even experienced pilots will

beneﬁ t from these basic ﬂ ight notes:

3S vs 4S

The Hadron is perfectly content ﬂ ying 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-ﬂ ight). On 3S with the 6.0 x 5.0 propeller the

motor draws about 33A static (about 21A average in-ﬂ ight). If you like to ﬂ y pedal to the metal you’ll ﬁ nd the Hadron is faster on

4S, but still ﬂ ies slowly well and performs ﬂ at 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 deﬁ nitely not slow at full-throttle!) and slightly lighter for even

easier launches and landings. The reduced current draw on 3S also results in longer ﬂ ight times.

Set a Flight Timer

If ﬂ ying your Hadron on 3S, set your ﬂ ight timer to 3-1/2 minutes.

If ﬂ ying on 4S set your timer to 3 minutes. Those are about the

minimum ﬂ ight times ﬂ ying 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 ﬂ ight 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 ﬂ ight time may end up

closer to 6 minutes on 3S and 5 minutes on 4S (or even longer),

but it all depends on your ﬂ ying 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 ﬁ rst ﬂ ight. It’s best to launch the Hadron on low rates and at full throttle. Simply hold it by the ﬁ nger

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 ﬁ rst launch by yourself, we recommend

that you dial in ﬁ ve to seven clicks of up trim just to make sure it climbs. However, that’s only for the ﬁ rst ﬂ ight; once the Hadron

is trimmed for level ﬂ ight, it will climb out rapidly regardless of launch angle.
