Congratulations on your purchase of the Extreme Flight RC 104 inch MXS-
EXP  ARF!  The  MXS  is  loaded  with  unique  features,  including  first  rate 
hardware,  components  and  thorough  instructions  to  ensure  a  trouble  free 
assembly and set-up. Weight saving components are used throughout, such as 
carbon fiber structural reinforcement, carbon 
fiber  wing  and  stab  mounting  tubes,  carbon  fiber  landing  gear,  titanium 
pushrods  and  a  carbon  fiber  tail  wheel  assembly,  all  ensuring  the  lightest, 
most high performance aircraft possible. You will notice there is a box built 
into the bottom of the MXS fuselage. This is a 
pipe tunnel and will accommodate most canister mufflers and tuned pipes sold 
for the current makes of 100-120cc gas engines. 
The performance ability of the Extreme Flight RC MXS-EXP is phenomenal! 
This  sleek,  fast  and  agile  airframe  is  completely  unlimited  in  its  ability  to 
perform  the  full  range  of  full  stall  high  alpha  maneuvers  and  aggressive 
gyroscopic tumbling maneuvers. The MXS is rewriting the rule book on ultra-
aggressive 3D maneuvers! Unrivaled in pitch and yaw authority, the MXS will 
be the machine that introduces a whole new level of gyroscopic gyrations and 
insane tumbles to the hardcore 3D masses. Rock solid in all aspects of current 
3D  maneuvers,  the  MXS  will  give  those  that  fly  on  the  bleeding  edge  the 
confidence  and  capability  to  push  through  and  break  new  ground  in 
expanding  the  rapidly  evolving  3D  flight  envelope.  Utilizing  the  same 
lightweight  interlocking  laser  cut  construction  and  carbon  reinforcement  as 
our  Extra,  the  MXS  is  capable  of  handling  the  most  punishing  maneuvers 
imaginable. We have spent a great deal of time and effort to provide you, the 
discriminating  aerobatic  enthusiast,  with  the  highest  quality,  most  complete 
package possible. We are very proud of the end result of our labor and wish 
you great success with the assembly and flying of your Extreme Flight RC 104 
inch MXS!
