TBM DV8R MANUAL  

Revised 1/4/2010

 

NOTE: This manual will be updated continually as new information is obtained.

 

 

The DV8R  (pronounced deviator) was PCM Model’s follow up to the AV8R (aviator) sport trainer jet 
but was a completely new model designed from the ground up to be a superior all around 
performance jet, hence the name (Deviator). Rather than simply “blow up” its smaller cousin we 
decided to create a model than has looks and performance usually found in far more expensive jets 
but in a package that fits a wide range of modeler’s skills. With its large size, light wing loading and 
generous landing gear stance, the DV8R  has an incredible flight envelope that will prove favorable to 
nearly any jet pilot. We are so impressed with DV8R’s flight prowess, its smoothness and its extreme 
stability at all speeds that we think you’ll agree that it will be one of the best flying models you have 
ever flown. TBM purchased the rights to the DV8R, and with minimal changes made it available as an 
ARF. 

                                                                                               Patrick McCurry 
 
Troy Built Models purchased the right to the DV8R from Pat in 2008. Several changes were made to 
improve the performance and ease of transportation. Incidences of the wing, stabs and turbine were 
changed to accommodate turbines of very high output without any trim changes. The wing is 4 pieces 
instead of 1 which allows the landing gear and all its components to remain connected if required. 
The outer wing panels are split at the intersection of the ailerons and flaps. With the outer panels 
removed, the plane is 44” wide, and can be easily rolled across the ground and into a truck on its 
landing gear. Also the wing was moved back slightly to eliminate lead in the nose for CG reasons. We 
changed the servos mounts so that they mount inside the surfaces rather than having the tops of the 
servos exposed for a much cleaner look. The trailing link landing gear necessitated a wing change. 
The trailing link gear is great for grass runways. The DV8R, as great as it was, is even better now that
