Integrated Performance Airframe-Drive System (iPAs)

If you own a Precision Aerobatics airframe or would like to get one – this is the real deal! PERFORMANCE OUT OF BOX!
NO COMPROMISES, NO MODS, NO HASSLE! What you see in our videos is what you get with iPAs.

Unlike glow aircraft where it is mostly the matter of bolting on a specific size engine, the options for electric flight gear are simply overwhelming and matching electric gear to an airframe is a complex task for the average modeler and quite often can be very confusing.

Most manufacturers direct their customers to acquire a “compatible” motor and ESC or at best offer a “Combo” package that comprises of off-the-shelf motors and ESC that would, in theory “fit” within the model’s power requirements.

Surveys we conducted showed that each and every EP models flyer experienced at least one if not more of the problems below

• Unpredictable handling problems caused by reduced wing loading due to over sized motors or battery packs or ancillary gear.
• Overheating or unwanted ESC cut outs due to over propping or undersized motors
• Handling problems due to drastic shift in CG and overall weight distribution.
• Unacceptable flight times due to inefficient “hot” motors or undersized packs
• Airframe structural failure due to increased aerodynamic loads caused by over sized drives and packs.
• Overheating and swelling of battery packs caused by serious drive mismatched.
• Less than optimum motor performance due to incompatibility with the ESC.
• Crashes as a result of servo gear failures caused by excessive loads on the control surfaces or exceeding the maximum airspeed limits.




We do not believe modelers should have to live with compromises in flight performances.

Through hundreds of hours of flight testing our airframe designs, we have established that there is a direct correlation between the airframe and drive system and one affects the other with consequences to the desired aerodynamic performance. That meant airframes and drives should not be treated as individual items isolation but as one whole system.

Due to the extreme lengths undertook in the design of Precision Aerobatics models, and the unprecedented flight testing period to finally achieve the aerodynamic characteristics we desired, we felt a complete solution for this airframe was necessary. As a result we have developed our iPAs, PA Integrated Performance Airframe-Drive System.

We embarked on this quest by first carefully selecting each iPAs component, considering each possible aspect. We then started testing each individual component of the iPAs and subsequently on the airframe itself ensuring impacts on the overall flight performance and aerodynamic characteristics caused by each component are identified and addressed and to ensure all iPAs components interact in full synergy as an integrated flight system within the constraints of the design specifications. Each component was then further refined until a perfect match meeting the performance criteria set are successfully achieved.
