The Heli-Max MX450 is a fully aerobatic-capable helicopter,
offering the performance and flying manners of a 60-sized
machine in a smaller, more convenient package. The MX450 is
fully loaded with precision machined aluminum parts for
smooth control without flexing along with a carbon fiber tail
boom and fin set to keep the MX450 light and more agile. The
recommended power system will give you explosive power off
the ground and more than enough power to do tick tocks,
tornado's, chaos's, and much more.
Take care to build straight and true. Misaligned parts will hurt the
helicopter's ability to perform the extreme aerobatics it is
designed for.
For the latest technical updates or manual corrections to
the MX450 visit the Heli-Max web site at
www.bestrc.com/helimax
. Open the “Helicopters” link, and
then select the MX450 ARF. If there is new technical
information or changes to this model a “tech notice” box will
appear in the upper left corner of the page.
In the hands of a capable pilot, the MX450 is an impressive
3D performer. But for this helicopter to perform to its full
potential, it must be properly equipped with all the right gear
(servos, batteries, receiver, speed control). There may be
more than one type and brand of radio equipment that can
be used. But based on extensive testing, following is the
equipment we recommend so you can get the most
performance out of your MX450 and assemble it as shown
in this instruction manual.
Transmitter
At a minimum, this helicopter requires the use of a six-channel
helicopter transmitter capable of mixing between the throttle
and collective pitch channels. However, to unleash the full
aerobatic potential of the MX450, you will need a computer
radio capable of at least two sets of throttle and pitch curves.
The Futaba
® 6EXH radio (FUTK60** or FUTK61**) is an
excellent entry-level radio for use with this helicopter. For more
programming capability, any of Futaba’s higher channel-count
computer helicopter radios will work very well.
Servos
You will need four servos for the MX450. The servos should
weight less than 10 grams apiece, and should have a
minimum torque output of 14 oz-in. A good speed rating is
also important for helicopters, and we recommend that you
choose servos with a speed of 0.12sec/60deg or less. We
recommend the Futaba S3103 (FUTM0037) or S3107
(FUTM0025) for use with this helicopter. Note: The Futaba
S3108 servo will not mount to this helicopter without
modification, and is therefore not recommended.
Receiver
You will need a 6-channel receiver for this helicopter. A
small PCM receiver is strongly recommended for the noise
rejection and failsafe capabilities that PCM offers. We
recommend the Futaba R146iP receiver (FUTL0601) You
will also need a single conversion crystal to use with this
receiver. While most Futaba receivers are sold on high and
low bands, the R146iP is not banded and can use either
high or low band crystals.
Low band (channels 11 – 35) Crystal FUTL62**
High band (channels 36 – 60) Crystal FUTL63**
**Replace the “**” in the order number for the crystals with
the preferred channel number. For example, if you want to
fly on channel 33, order crystal number FUTL6233.
DECISIONS YOU MUST MAKE
CAUTION: Be aware that the MX450 is
operated on the same frequency band as larger R/C
models. If flying your heli within five miles of an R/C
site, there is a real possibility that you could be
operating your model on the same frequency (channel)
as another R/C pilot. If this happens, a crash will
result—with the person flying the more expensive
model suffering the greater loss (and having greater
potential for property damage or injury). The best thing
to do is to join an R/C club and fly at the site where
frequency control measures will be in effect. If you
insist on flying elsewhere, always be aware of your
proximity to R/C flying sites.
