The UAV CG machine is the third generation of the Xicoy device specifically designed to be used with UAVs.
It will let you check the weight and CG of your vehicle up to 100 kgs, with your smart phone within a few seconds. Our Ultimate Jets certified machines also allow to do this with a fantastic precision of less than 2 mm/ 2 grs !
As such, this is an essential accessory to industrial and professional.
All of this is achieve through your phone's screen via a tiny BlueTooth module that connects to the scales with regular servo cables. The files can be sent by email to your PC for auditing and to create proper weight and balance sheets ( electronic spreadsheets supplied with the machine ).
The device consists of 3 gen 3 precision digital mini scales ( 2 g resolution, made in Europe ) and 20 cm cones, connected to a small BT device
the cones allow to place the vehicle on the scales without the need for a landing gear.
Gen 3 scales feature a new set of aluminum covers with 2 screws for added stability, a slightly different seating on the measurement beam and a different base.
The mobile phone software is designed to give you:
1. The total weight of the model ( up to 100 kgs ).
2. The distance of the actual CG from the reference CG position.
3. Weight to subtract/ add at a given location to obtain the reference CG.
The procedure to use the device is as followed:
