FMS Pitts with SAFE Rx maiden flight (3 min 49 sec)

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 guess if we ever get the chance to buy these directly from Horizon we will have options to match our use case unlike the EFLR310013 Apprentice Rx.

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

The Hummer EPP 3D is a high performance profile foamy.
The Hummer's ultra-durable EPP construction and carbon fiber reinforcement means that it can really take a beating. This is ideal for pilots looking to practice 3D manuevers without the fear of destroying an expensive balsa model.

The Hummer EPP arrives in kit form, so you will need to add your own electronics. The build is straight forward. A detailed assembly manual w/photos is included but is lacking, found some good vids on You Tube.

Simply add your own 1000KV brushless motor, 1047 slow fly prop, 20A ESC, 4 x 9g servos, 4ch radio system, 3S lipoly battery and your ready to fly!

After weeks of trying to find an alternative to the stock plastic retracts (FN301)
I found on the FMS web site the E-Retract004 E-Retract Set For 1400mm F4U/P40 with metal trunions

So I bought them, and found that there is no main landing gear sold separately for the P-40. I tried the 1400mm F4U, but they were too short. I emailed FMS and they said to use the set from the P-40B. But they do not work either! I took measurements of the stock gear (see attached pic) and asked for some help from the forum members with measurements of their systems, but I received no reply, so I decided to disassemble my old set to see if I could remove the shaft and swap it into the E-Retract004 and I did!

Below are a series of Pics showing the steps with descriptios.
I also replaced the wheels with spare ones I had from my FMS 1400mm P-51B Shangri-La, they fit the well perfectly, I just had to open the axle hole with a 3/16" drill bit.

I also borrow a modification from the P-40B thread to change forward "rake" Reading

Airfield’s latest 6 Channel T-28 Trojan comes powered with a potent 4250 580KV brushless outrunner motor that provides sport aerobatic performance and enough power to climb with ease. Its tough EPO (Expanded Polyolefin) construction is exceptionally resistant to damage and can be easily repaired with any medium-viscosity CA or epoxy.

Installed SAFE Rx rotated 180 degrees in order for SAFE correction to operate ailerons in the correct direction without reversers. Reversed Aileron channel in DX9.
Rotated the servo control arm for the elevator 180 degrees for SAFE correction to operate elevator in the correct direction without reversers. Reversed Elevator channel in DX9.
Connected Flaps and Retracts to Aux 2 with standard "Y" cable, no revers needed. Programmed Digital servo in DX9 for Aux 2 on switch D

I had to replace the ESC as I had not throttle, used a Turnigy® TRUST SBEC PRODUCT ID: TST-BEC45A.
I placed the EFLR310013 SAFE reciever in the center of the bay with the standard forward orientation, bench test showed that SAFE was operating the ailerons backwards as compared to Jim's video in post #1 so rotated the receiver 180 degree so it was facing backwards, this corrected the ailerons, but now the elevador was back wards, I had to cut away a small piece of foam holding the push rod and was able to move the servo arm to the opposit side. I connected the "Y" cable provided for the Bomb drop to bot the flaps and retracs and programmed my DX9, Aux2 on Switch E and digital Switch Setup of POS 0: -70%, POS 1: 35%, POS 2: 100%

This is my first contribution to the Master List of other planes with the EFLR310013 SAFE receiver.
The receiver bound with no issues.
There is very little room in the receiver compartment so I installed the reciver on top of the wing.
I rotated the motor 180 degrees to route the ESC leads through the bottom vent and enlarged the top vent to hold the 3S 2200, 3S 4000, and 4S 2500 battery.
I used carbon fiber rods to create a battery tray and one as a battery stop.
I had to install the receiver backwards for SAFE to work correctly with the ailerons, no other changes were needed.
I used a reversing "Y" cable on Aux 2 for both Flaps and Retracts.
See the programming in my blog for the P-51D, I just copied that model on my DX9.
