INTRODUCTION

Thank you for purchasing the Flyzone Extra 300SX. The 

Extra was originally intended as a 3D-capable platform, 
but because of its power-to-weight ratio and well-
mannered fl ight characteristics, the Extra is also a great 
sport fl yer for average pilots when the control throws are 
set to low or high rates.

ADDITIONAL ITEMS REQUIRED

Radio System

The Extra 300 can become airborne with any 4-channel 

radio system, but to take advantage of its sport fl ying 
and/or 3D capabilities a modern computer radio with 
standard features such as a timer, channel mixing, dual 
rates and exponentials is required. The Tactic TTX650 or 

TTX850 are both viable options that fi t this criteria:

  

Tactic TTX 650 6-channel SLT computer transmitter 
(TACJ2650)

  

Tactic TTX 850 8-channel SLT computer transmitter 
(TACJ2850)

  

Tactic TR624 6-Channel SLT Receiver (TACL0624)

  Batteries for transmitter: 

Hobbico HydriMax 

NiMH 4-Cell 4.8V 2000mAh Flat AA receiver pack 
(HCAM6321) 

OR

 Duratrax Onyx AA Alkaline Battery 

(4-pack, DTXP4704)

LiPo Battery

The Extra was primarily designed as a 3D-capable aircraft 

with a 3S 1800mAh LiPo. A 3S 2200mAh LiPo is also 

suitable, but the additional weight of a heavier battery may 
detract from its 3D performance slightly. In any case, if 

you start experimenting with batteries and propellers, be 

certain you don’t exceed the ESC’s maximum 30A rating.

  

3S 11.1V 1800mAh 30C LiPo (GPMP0855)

  

3S 11.1V 2200mAh 30C LiPo (GPMP0861)

  

For additional batteries, adhesive-back hook-&-loop 
Velcro is also recommended (GPMQ4480)

LiPo Charger

The bare minimums to look for in a charger are LiPo 

balancing and the ability to charge at a minimum rate of 

1C. An LED readout and AC capability are also convenient 

features. The Great Planes Triton EQ AC/DC charger meets 
all the above:

  GPMM3155 Great Planes ElectriFly Triton EQ AC/DC 

Charger
