About this 3D model

This quadcopter is about 22mm longer and 2mm taller than the popular [T4 Quadcopter Mini 250](http://www.thingiverse.com/thing:304237). It supports up to 8" props and a 2200mah 3S battery.

Everything is secured using 2.5mm zip ties. - includes two arm options - 28mm, and 30mm motor cup (inside diameter). The 30mm cup has slots for 3mm motor bolts (the other is 2mm). - strong braced tube section arms with plenty of room to conceal motor wiring - designed for a 3S battery (up to 2200) located right in the centre of rotation/thrust (110 x 38 x 24mm capacity). - plenty of space to mount ESCs - concealed but still well ventilated for cooling. - top plate has space for a variety of flight controllers and a Mobius style camera. It also features 3mm mounting holes so stand-offs could be used to add an additional deck of components. Alternatively two hex holes are available to add 3D printed posts and rear upper deck. - RF "invisible" frame - as opposed to carbon fiber or aluminium - Sketchup file included so you can make changes to suit yourself ###Revision History **2 September 2014** [Legs for your T4 Mini](http://www.thingiverse.com/thing:448694) are now available. **31 August 2014** *Version 1.3* Added a bridge to T4Mini315VibrationFloatingPlate.stl to make it less flexible. No other files were changed. **15 August 2014** *Version 1.2* New vibration isolating top plate option. This option is compatible with previous body and all other components. It replaces the top plate with one that has mounting points for [65 gram vibration damping balls](http://hobbyking.com/hobbyking/store/__40603__Vibration_Damping_Ball_65g_Bag_of_8_.html) that then connect to a new floating plate to hold your flight controller and camera. New files: - T4Mini315VibrationTopPlate.stl - T4Mini315VibrationFloatingPlate.stl **30 July 2014 - Version 1.01** - there seem to be a lot more 8" prop options so I've added two arms to suit 8" props (28mm cup and 30mm cup). - extended the 7" arms by 5mm to give a bit more clearance from the body. - modified the body to raise the arm sockets so there is a bit for material in the bottom of the socket - stronger to support longer arms.
