I managed to get my hands on a couple of these receivers through RGC one from the Spitfire and one from the Timber, at first glance they are indiscernible unless their labels are in tact. The Spitfire is labeled THM603X and EFL8650V1. The Timber is labeled THR605X and EFL5250V1. Why is this important, they work the same way right?
Why becuase the factory orientation is different for each. For the Spitfire the servo connectors are facing the front and for the Timber they are facing aft.

I have decided to start my bench testing where it all began when Suenaga (Jim) fitted his E-Flite Dallas Doll with the Apprentice Rx. I can tell you that if you are using the Apprentice Rx today, the Timber matches the orientation and fits in the same location, HOWEVER the elevator needs a reverser. (Same for the Spitfire)
If you use the Spitfire you will need to extend the cables for the rudder and elevator so if you buy a long reverser you can kill to birds with one stone so to speak.
I did have to get a little creative with the routing of the cables, but it was no big deal.
I then setup all of the conrtol serfices according the the Mustang manual. It was nice to have the gear and flaps work independently as was intended and to add that elevator flap mix according to the book.
I tested both AS3X mode and SAFE mode (using the mode switch)...Continue Reading
