The tough 250 racing quad

thingiverse

been testing multiple types, models and makes of motors,escs and FC's of late and no matter how good a design of 3d printed hardware is, it'll only stand up to so much testing punishment before your printing replacement parts more than your test flying lol, so I decided to make a small compromise in the build by using a Diatone 250 single piece frame as a base for modification. these frames are available from HK as the "FPV250" frame for around the 7 quid mark and uptil now has been near on indestructible..... they really are shockingly durable, which makes them ideal for use as a test rig. base frame....http://www.hobbyking.com/hobbyking/store/__66324__HobbyKing_8482_FPV250_Quad_Copter_A_Mini_Sized_FPV_Multi_Rotor_kit_AR_Warehouse_.html lower platform accommodates either 4x (upto) 12A escs or the quatro or Q-brain 4in1's. (alternative escs on arms and PDB/Wiring bundles on platform FC (frame) platform accommodates anything upto a multiwii or KK2.1 board in size. Upper platform offers FC protection and maybe somewhere for GPS receiver or VTX. Battery bay accommodates upto a Turnigy 3s 2200 in size. RX can go on the back platform while cam hung off the front. should be a nice tidy compact piece of kit when Im done........ fingers crossed that is Print Settings Printer: Colido Printrite diy 3d printer Rafts: No Supports: No Resolution: .3 Infill: 30% Post-Printing update: (17/5/2016) finally got round to building the tough250 and my oh my what a little monster it is: CC3d-nano Q-brain 25A 2200mah 3s 25c turnigy 1950kv Keda outrunners Radiolink 7ch 6x3 bullnose props (my own) 742g full loaded. as you can imagine its quite gutsy to say the least (I may even downsize the props to rein it in a bit), holds altitude at around 40% throttle so has bags of reserves even using a 30c max burst lipo (thats tbh getting on age wise too), gonna spend a few days putting it through its lighter paces before I see what it can do acro wise on new lipo's (IM SO ORDERING SOME 40C-50C BURSTS FOR THIS lol) hope ya all like it and enjoy. UPDATE: (26/5/2016).... added battery enclosure&FC plate, redesigned top plate & lower plate, added canopy design changed entire power system to:- LDPower MT1860-2280kv D200, 10amp escs...... it was silly fast before, now its just plain terrifying, flight time has increased to 12-14mins light use, 7-8 heavy use on 2200mah/3s and weight has dropped to 526g total (inc. lipo) UPDATE: (28/5/2016).... I just cant help fiddling with this.... fly's great plenty of power just needs better looks added:- new upper plate design (its essentially a canopy mounting plate now) added:- new split canopy design to allow gps/vtx/receiver aerial passage and better electronics protection. (and looks) UPDATE: (31/5/2016) Added alternative battery mount/landing legs added alternative lowerplate to suit UPDATE: (06/06/2016) added alternative lower plate with LED mounting points
