How much does your 250(s) weigh? What do you do to reduce weight?
250 mini quadcopter Weights |
31-Jan-2016, 08:26 PM my ZMR250 and EVO250 weight around 720g including GoPro and Lipo... my Speed Addict 210 and Ghost 220 weight about 600g including GoPro and Lipo.... things you can to reduce weight on Mini quad: - shorten motor/ESC wires as much as youcan - solder motor on ESC directly not using bullet connectors - Use 2 motor bolts instead 4 (not recommend unless you are willing to take the risk ) - use nylon standoffs - use light weight components such as mini VTX, littblebee/dys ESCs 31-Jan-2016, 10:03 PM Armattan F1-6 667g with RunCam2, immersionRC 5.8GHz, X4R-SB, integrated PDB, 1800mAh LiPOs - Shorten every power lead as far as you could. - Don't use hot glue - Isolationtape instead of zipties. Sky is where the fun begins!

I was a little concerned about it being too heavy, but it's nice to know it's in around the same range as other 250s. I have a Mobius camera, which definitely saves on weight. Honestly, with weight being such an important part of multirotors, I'm surprised people use GoPros. I really like the idea of soldering motor wires directly to the ESCs. I definitely have some optimization to take care of with lengthy wires. 02-Feb-2016, 10:58 AM My LS210 weighs 299g without lipo and 450g with(1300mah 4s). No recording camera used.

Could probably get it lighter. 05-Feb-2016, 06:03 PM My 250 is 288.7 gm w/o battery & 411.9 w/ 1500mah 3s battery. No FPV gear, yet.

What do you do to reduce weight? I built my first 180 class yesterday and saved 29 grams by cutting and soldering a bit - cut motor wires and solder them to the esc - cut down power wires from esc - cut and soldered the control wires to the flight controller - changed from PWM to CPPM (only 3 wires from RX to FC instead of 8) (cut length and soldered to FC as well) All in all 29 grams - a LOT more than I thought before I started. So next week it will be the surgeons office for my 250 as well.

That is quite a bit more than I thought. Once my FPV gear arrives, I will be shedding some extra wire weight! We'll see if I can beat 29 grams. 250mm Diatone CF Blade w/ PCB, CC3D, DYS 1806 2300kv, & DYS BL20A 411.9 gm w/ 3s 1500 Nanotech & HQ 5040 (Clocked @ 47 mph LOS with GPS) FPV gear on the slow boat... 06-Feb-2016, 12:14 AM (05-Feb-2016, 10:53 PM)RndmGuy06 Wrote: That is quite a bit more than I thought.

Good luck I'll see if I can get a picture of the cabling mess I cut away and the finished result when I get home on Sunday. I should have taken a picture of the testing setup I had with the original cable all messed up. |
