Catalyst Machineworks RD5R

After the successes of the Merica 5 on the racing scene, Massive Droner on the 2.5 and 3" micro sphere and the Smooth Operator in the freestyle World, Neill and the team pilots from Catalyst Machineworks went back to the drawing software; especially Neill in fact, we just "yell" at him to make mods super rapidly when we don't like what he brings on the team chat even if, most of the time, he's on the spot. Yes the life of a professional drone designer can be very tough at times !

The RD5R is inspired by the 3 last frames released by CMW mentioned earlier and basically brings most of the advantages of them and minimizing some inconvenience spotted/reported throughout the past months/years.
The proven design of the arms of the Merica have been brought back to this design and good news if you decided to switch from Merica to the RD5R, your 5, 6" arms will be a perfect fit on the RD5R !

Base plate is moving from the stretch X or the pure X towards a wider front geometry and a standard stretch rear design. I'm no racer but the racing boys of the team reported after many tests that cornering was a wee bit better however, they also mentionned that the position of the camera could trick the feeling they had on this matter. Seeing no disadvantage on this geometry, the decision to keep it was adopted.
As a freestyle guy, the advantage of this geometry is no props in view, as we will see it later, freestyle line of accessories are available for this frame too.
The canopy that, apparently, kept some Merica enthusiasts away from the Merica frame was abandoned and instead of a typical spacers/top plate type of frame, it was decided to use the Massive Droner side plates design.

The side plates are locked by 2 front braces and a huge TPU part on the rear of the frame holding the Rx and VTx antennas; an idea developed and coming from the Smooth Operator. The front brace was doubled by a second intermediate brace to rigidify the entire front area where the camera is located. This also shows, during the testing phase, an increase in resistance to front hits. Thanks to Ryan for sacrificing his prototype to science by going at almost full speed in a tree. Yes we really test frames.

A TPU part comes between the side plates and increase the sexiness of the frame. A "turtle mode" fin was added for the racers and another TPU part supporting a variety of GoPro mounts is also available for freestylers.
The frame weight with no TPU part is 75g and TPU adds another 10g.

Detailed pics of the prototype, please ignore the shiny carbon parts, production frame will be in mat carbon

Frame ready to fly before pack.
Since the 4in1 ESC I was planning to use fried (thanks Spedix, 3/3 4in1 ESC fried in less than 12months ) I had to use an old 4in1 ESC with no BEC therefore, regulator I had available + heat shrink + double sided tape + wires =8g.
Saving 10-15g would be extremely easy as wiring is not optimized at all, a lighter strap would also save another 2-3g.

Is there a way to zip tie the XT60 pigtail to something to provide some stress relief in a battery ejection?

You can use an arm to do that, works really well.

Hi everyone! I've been torturing this RD5R on the track for a couple of weeks and it is really impressive! Great cornering feel with the wider front geometry. Low camera position instills confidence in dives and advanced maneuvers. I'm flying it at 274g dry weight with 2205 1750kv and it is performing nicely. Here's a video of it in action on my practice track.

Beware 30mm x 30mm Mamaba Stack by Diaton do not fit in it. The frame is too thigh in length. Except for that. It is a great design.
