The Parkzone RC Extra 300 is a very powerful aerobatic, completely ready to fly, scale RC plane.
There was a time, not that long ago, when the only way to own a fully aerobatic, scale RC plane like the Parkzone Extra 300, was to spend months building from a model aircraft kit.
Now you can just spend your money and receive a completely finished and ready to fly model, right out of the box!.
Typical of all the Parkzone RC airplanes, it is just a matter of bolting on the wings, sliding the tail through a slot and retaining it with tape and charge the battery.
As can seen in the photo, it comes with a very bright color scheme and has a contrasting colors on the bottom that really assists in knowing which way the model is flying.
The model is constructed from Z-foam. This high density material is injection molded and produces a tough smooth surfaced airplane. The Extra 300 has been available for a while now and has become very popular. It is definitely not intended as a first model. It is very powerful and is neutrally stable, This means it goes where it is pointed and stays in this position until the pilot enters a new command.
This attribute is great for aerobatics but no good at all for beginners! The 15 size outrunner brushless motor will pull the Parkzone RC Extra 300 straight up until it is out of site. All of the usual maneuvers are possible, including knife edge, snap rolls and aileron rolls with virtually no pitch or roll coupling. When slowed down it has a very stable slow speed performance that should make landings easy.
The wing span is 40.6" and the weight is 34.5oz. It can fit inside most vehicles in one piece, but if space is limited then the wings are plug in and can easily be removed.
The wing slides onto the composite material, black tubes and each panel is retained by a screw.
The only tool required for assembly is a screwdriver.
This Parkzone RC airplane is really not intended to be a 3D style airplane but a fully aerobatic conventional maneuver airplane. As far as shortcomings are concerned I have heard very few.
The color scheme on the bottom is the same color as the top, which can cause an orientation problem. Maybe the addition of a few stripes of tape could fix that.
Some flyers have complained about the landing gear pulling out. This is an all foam airplane and landings must take this into account! Keep them as smooth as possible and on as smooth a surface as you can find. If you do pull out the gear I am sure it can be fixed with epoxy or Gator Glue.
This unit is the E-Flite 30 amp Pro Switch, BEC brushless RC ESC. It can also be used in future projects.
It can handle up to 30 amps of continuous current, as long as cooling airflow is allowed to keep the unit from overheating. The unit can drive up to 5 analog or 4 digital sub-micro RC servos. Voltage cut-of is one of the many programmable features.
Either a 3S (11.1V) or a 4S (14.8V) lipo battery can be used.

This is the motor installed in the Extra. It is a 15 size outrunner brushless motor.
it has a rating of 950Kv

These are the aileron servos installed in each wing panel. these are the Parkzone SV-80 long lead servo.
The rudder and elevator servo are as seen here, These are Parkzone DZV-130 digital, metal geared servos.
They should have an excellent life and being digital will be accurate and very repeatable.
All of the above components are common to both the BNF and PNP versions of the Extra.
Here we see a photo of the receiver, built in to the BNF version of the Parkzone RC Extra.
This is the Spektrum AR 500 DSM2 5 channel sport receiver. One unique feature of this receiver is the extra aileron port. This allows a second servo to be plugged in, rather than using a Y-harness.
Here we have the lithium polymer battery. This is a 3S 2200 mAh unit. This is a big battery and should give 8-10 minutes of flight time.
Here we look at the charger that is included in the BNF model and does feature balanced charging. This feature ensures that all cells are charged equally and reduces the risk of fire, that was a possibility with early lipo chargers.
The charger requires a 12V supply and comes with a cigarette lighter adaptor. You can plug this into your car and recharge your Parkzone RC airplane, as many times as you like!
If you need a new RC transmitter, then this is one I really recommend. It is the Spektrum DX6i. This is a 6-channel 2.4GHz unit, that can be easily bound to the Spektrum receiver, in the Extra.
It is a computer radio that can be used for helicopters as well as aircraft.
