EXI 450 Line Review
Note: The 450 line is mostly
gone. The 450 Pro line is better and reviewed here:
EXI 450 Pro (The Align Pro Clone
has a number of 450 sized heli ARF kits. Their offerings, prices and
bundles may change from time to time. This is an overview of various
older models and my opinions on them.

EXI 450 SE CF
This kit is
by far the best overal Kit I recommend. It's price points is good and
worth the added amount over any of the other kits Xheli offers.
An almost direct copy of the Trex 450 SE V2. What you get
the cheaper kits is:
SE CF setup
- CF frames
- Metal Main bearing blocks and front boom block
- CF horizontal and tail fins
- All Metal Head and Tail. Head has thrust bearings
- 325 Fiberglass blades (vs. plastic like some of the cheaper
- Nice looking Fiberglass canopy
EXI 450 V2 Plastic
This is the least expensive version and the one to choose if your are
going on the extreme "Cheap" side of things.
can tell you that plastic will break more often in a crash than Metal.
So if your a beginner, your still better off getting the SE
version. A sport flyer who wants to spend less up front and
upgrade later (to a metal head/tail) may want this version to start off
with. I would not run my headspeed over 2800 RPM with this
helicopter though, I don't think the head will take it for long.
The tail has more slop than the SE CF version as well which
affect your tail holding ability.
EXI 450 LE, ZL &
SE versions (Obsolete)
3 versions have 3 bearing blocks supporting the main shaft. The LE has
the traditional inverted motor mount and the SE & ZL has the
mounted on top. The SE and ZL while not direct clones are similar in
structure to the MiniTitan. Some people favor this design for
scale applications because of the larger battery mount that allows the
battery to be mounted more forward on the helicopter. The SE has the
3mm feathering shaft (like the Align SE) vs. the 4mm tapered down toe
3mm like the SE CF or Align SEv2. The ZL and EL have the 4mm
(SEV2 style) feathering shafts. The ZL has a programmable head that
allows you to change ball link locations to affect roll rates. SE has a
full plastic flybar cage. LE has a plastic/metal flybar cage and the ZL
is all metal flybar cage. ZL has CF frames and all metal head/tail
while the SE and LE have plastic tail and metal w/ Plastic head. The
mainshafts on all 3 of these are NOT trex 450 SEV2 compatible and will
only be found at Xheli. So if you order these, make sure you get
mainshafts for spare parts.
is pretty much an ARF version of the Exceed Genesis. The mainshaft is
different than an Align SEV2 so get spare main shafts if you order
this. The tail belt comes all the way around the mainshaft
means there is no front belt pully slippage. It is slightly more
efficient and will be a little quieter than the other 450's.
is the arf version of the Blueray with a few upgraded metal parts. SEV2
part compatible except the frames. Firberglass frames flexes a little
easier than CF so it survives crashes better. Metal head/tail
blocks as well as tail servo mount. Servo configuration is
different in that 2 are in the back and one is up front. Plastic Canopy.
MB450 V2 (Obsolete)
version is similar to the MA 450 but the frames are wider and not
split. The innner part of where the main shaft supports is redically
different and allows the cyclic servos to be easier (once you figure it
out) to be mounted, accessed and serviced. The frames are
fiberglass which flexes a little easier than CF so it will survive a
crash better than CF or metal. Head is metal and crash parts save the
frames are Align SE V2 compatible. Head mechanics are similar
the Exceed Blueray.
any ARF heli kit, you MUST re-loctite all the metal to metal fastiners.
Indluding the head and tail screws. This is a must and you
do this for your own safety and the safety of others. This is no
different than what MUST do to other helis you might get from other
manufaturers other than EXI. If you find a screw is really
heat it up with a soldering iron tip to loosen the loctite. The
feathering shaft screws inside the blade grips as well as the tail grip
shaft screws are known to be very tight on new helis from EXI.
Inexpensive Fiberglass blades are good for this
helicopter, especially at the beginning when your getting used to it.
But Carbon Fiber blades will really show what this helicopter is
capable of as well as have less tracking inconsistances compared to
fiberglass. The EXI 450s will support 335mm
blades (Xheli and Hobbypartz sell them). This will reduce
roll rates but will make the helicopte fly more stable.
You can follow the Align 450 manuals for setup as well as my other 450

One thing I did mod on the helicopter was I put a chinese
onto the tail grips
