Message from BMI Racing

The Copperhead 10 was designed to use mini 

servos.  While any servo will fit the ideal weight 
distribution is best achieved with a min servo such 
as the Futaba 9602,  3650, JR 3650, etc.

The Copperhead 10 is the first 2

nd

 generation World GT car.  After two years of racing and testing we had more than few 

good ideas that we wanted to incorporate in our next World GT car.  As the concept for the new car started to come 
together we realized this was not going to be a DB10RRR.  There we too many subtle tweaks, changes in suspension 
geometry, altering the chassis torsional stiffness as well as optimizing the car for the latest Brushless/LiPo power systems. 
 The result of all of this is the Copperhead 10.  This car is everything the DB 10R was and much, much more.  All the 
changes focused on expanding the cars setup envelope.  This means its is easier to get the car setup on a wider variety 
of surfaces.  From  club races on low grip parking lot tracks to the carpet at the A-Main of the Snowbird Nationals, the 
Copperhead 10 can easily be setup to win.

Please read through the instruction manual carefully.  Even if you are an experienced R/C racer, there are some details 
about the Copperhead 10 that are different. To get the most out of your kit you must have it assembled correctly. 

With Regards,
