QUOTE(zeroglyph @ May 11 2016, 02:40 PM) never tried draining li-ion below 3v. probably not enough power left after that point. below 500gm for 10Ah 3s is very good ..http://batteryuniversity.com/learn/article..._of_lithium_ion typical operating voltage is 3volts, lowest. a protected version will also cut off at ~3volt. so i wouldn't go below that. only if u use the LG MJ1 18650 la my 2500mah samsung 25r weighs 45gm on its own but if it works for u then thats good but low current output not for me i suppose ... too much of the occasional speed junkie |

QUOTE(zeroglyph @ May 11 2016, 03:18 PM) i think you're replying to the wrong post 20a is nothing in the world of speed ... INR18650-25R is a high discharge, those are heavier and more expensive than typical 10A li-ion. good for sub-ohm vaping though even if u multiply it by 3 by running 3 parallels |

QUOTE(zeroglyph @ May 20 2016, 10:20 AM) it's a variation of THIS. unfortunately it doesn't allow configuration for each motors, so have to use the tx calibration method. i clicked in the linki read the few reviews that it had underneath 2 drones flew away by themselves ... hopefully yours has no such issues la |

FC must have baro compass and gps as well as the usual gyros and accelerometers la cheapest that comes to mind is the APM |

QUOTE(zeroglyph @ May 27 2016, 10:48 AM) thanks yes ... magnetometer is compass ... this is for direction of the aircraft is pointing at lamagnetometer is basically the compass, right ? if i just want hover hold, i don't need the GPS module, right? FC with barometer is enough? i'm planning on a sub 300 frame(250-280), so the whole GPS thing might be a little too cramp. so trying to isolate the functions gps is for position of aircraft baro is pressure sensing ... for altitude control if altitude is all u need then go for rev 6 naze32 la .. it has baro already and that board is ez to tune and set up or any board that has a baro la .. lol your above choices are good oso QUOTE(josh5671 @ May 27 2016, 11:54 AM) http://www.lelong.com.my/kx/nitecore+charger.htm ? yes it can charge any number of batt at any 1 time 1 or 2 or 3 or 4 together oso canThe price are pretty large range.Will be something fake or clone inside there? What nimh battery i should use. Does that I4 or D4 nimh charger support change 2 only cells one round? Because my transmitter need 6 cells, if one round charge 4 cells, another round will be 2... **Please help me choice which reseller are something you feel good to bought with check out this ... https://www.facebook.com/vapeitmalaysia/pho...?type=3&theater they ran out of 4 batt charger ... but u can still buy 2 x 2 batt charger ... more flexibility oso ... and its super cheap compared to the prices at lelong This post has been edited by QiW: May 27 2016, 12:17 PM |

QUOTE(zeroglyph @ Sep 20 2016, 04:28 PM) a question on GPS module. is there an orientation in which to physically install it? if compass module is incorporated into that GPS module unit ... then YESi've managed to setup mine, getting a lock and everything, but do i need to pay attention to the physical orientation? |

QUOTE(ZZR-Pilot @ Nov 10 2016, 11:05 AM) The spinner that spun off and disappeared after snagging a plastic bag did have blue threadlock in it. I noticed this problem is more pronounced on CW props, because the direction of spin tends to undo CW nuts. And those spinners are not cheap (about US$1 each), I can't afford to keep losing them on a regular basis. check see if u have those prop nuts the correct direction ..It happens in all modes. I'm going to recalibrate my transmitter & CC3D then I'll dial in a new, flatter throttle curve on my transmitter. We'll see how that goes this weekend. loosen the nut hold the nut with yr hand ... then rotate the motor in the direction that the prop will rotate when throttle powered if the direction is correct then the nut should tighten itself onto prop and motor if it doesnt tighten then u have the directions of the nuts/prop shaft/motor wrong |

Just completed building and assembled my rarest R/C jet model today which much sought after by R/C collectors. The black F-14 TOMCAT "Playboy" VX-4 squadron. Took 2 days to complete and powered with twin high KV 55mm EDF turbine and high torque servo to swing the wing sweep in place. Took me years to find it online so i could pair it with my other existing "F-14 Jolly roger". Now both looks happily together in my hangar.
