Redback & Classic Mod

[Van]

I am after some advise 

I have an Airborne Classic with a good 582 grey head and the frame is in poor condition 

I have an Redback with a 503 at end of its life and a mint frame 

I want know can I swap the engine and mount over on them so i have a good motor and frame combo 

I have the manuals from Airborne and they don't show any difference in the frame construction 

Some advise would be great 

Thanks Van

Best to contact Airborne directly for the answer.

As Mc Guyver has said, you will need to check with the manufacturer.

 

As these trikes are considered "certified aircraft" then you need to be very concerned with the ongoing airworthiness, and you will probably be at the wrong end of CASA if you swap these over without a paperwork trial from airborne.

Physically can you swap them?  Yes - they have the same mast bolt patterns. 

Technically should you swap them - maybe not - the hang angle between the two airframes is slightly different and your thrust line with reference to the hang angle makes a BIG difference to handling on a trike and I am not certain the thrust lines will be maintained between the two airframes.

Legally are you allowed to swap them - NOT WITHOUT AIRBORNE CONFIRMING IT IS WITHIN THE DESIGN CERTIFICATION AND NOT UNTIL YOU HAVE FOLLOWED THE RAAUS/SAFA MODIFICATION PROCESSES AND SIGN OFFS.
