The EXI 250 is a fully capable 250 class
rc helicopter. This helicopter is quite
small and capable of doing just about
any 3D maneuver. At a quick glance one
can't help but notice the EXI 250's
striking resemblance to the T-Rex 250.
Although it's not an exact clone, it does
share an almost identical frame design.
The EXI 250 is aggressively priced much
lowered- and with that price point it will
undoubtedly appeal to anyone who
wants to jump in the hobby.
Parts Needed to Build The Kit
The EXI 250 is a kit, meaning it does not come
with any electronics. There are many choices
for electronic parts, so here are the basic parts
you will need.
Transmitter
I use the DX6i, a great
transmitter at a good
price.
Receiver
The AR6200 Rx comes
with the DX6i (when
bought new) but for a
250 you would want the
smaller AR6100 Rx
Brushless Motor

Align 250SP
(3400KV) RCM-BL250SP
Brushless ESC

30A
Head Holding Gyro

There are lots of HH
gyros available. A
good one will make
life easier
(4) Micro Servos
LiPo Battery

11.1v 800mAh
