I've had a set of Marspower 3508 700kv motors for a few months that I've wanted to use on a short range FPV build in the range of 450mm, problem was I couldn't find anything in this range that would work with the 3508s. Then I found the Aerial Mob arm set that are made as an upgrade for the DJI F450 arms on the TBS Disco. And it just so happens that the 3508s fit them perfectly. TBS recommends the Naza-M flight controller for this but I have a spare Tarot ZYX-M FC I'll be using. For a smaller build it's perfect as I find it much snappier and locked in than the other GPS FCs. I've got the motors installed on the AM arms and I must say, they are extremely high quality and will make for a very clean looking build. Other parts to follow are: Aikon 30A ESCs GH 4S 35C 5000mah lipo Lumenier CS-800 FPV camera Gitup Git 1 video camera TBS Unify 200mW tx TBS Triumph vtx antenna Radio system - Radiolink AT9-S TX & RD9S RX More to come.....

Also, is your vehicle equipped with the Disco gimbal?
Yes, the AM arms are part of the endurance upgrade. But 3508 motors I have won't fit on a standard Disco. I'm not interested in longer range, but with these arms I at least have the option of going up to 12" props. No gimbal, as I have a Tarot 650 that has a decent setup for video. But if I was to get one, it would probably be the copterlab unit. http://copterlab.com/2-axis-brushless-go...-discovery
Got a little bit more done last night. On the bottom plate, pigtail and TBS Core soldered on and Tarot FC put in place. Most guys just use zip ties to fasten FPV camera to the mounting board but I found some standoffs from a micro frame that worked perfectly. With the Core, you can see there'll be next to no actual wiring for the FPV system. Camera to core is only a couple cm and the vtx will be mounted on the top plate directly above the vtx in of the core so only 3 or 4 cm of wire there. I do have a Tarot OSD but I'm going to hold off installing that ATM
Soldered the 2 sets of header pins onto the top plate last night. This is a nice setup with the receiver connected to the rear pins and traces in the plate going to the front pins for connection to the FC. So the radio system is totally isolated from the FPV system up front, which should make for very little interference. I also decided to mount the PMU for the Tarot FC on top for better air flow. Next step is to get the Tarot OSD installed. I'm going to overlay it on top of the TBS Core OSD and hope it looks OK on the video screen
