QUOTE(wallydragon @ Aug 22 2016, 02:29 PM) Thanks wallydragon. QUOTE(josh5671 @ Aug 26 2016, 11:10 AM) https://docs.google.com/spreadsheets/d/1XHD...#gid=1787130452 Sound like "PID" problem. Did you already adjust the Yaw gain? or did you already calibrated each ESC throttle end point?Now I had a Deadcat 450 Quad build as above. Spec: 2212 980kv cheapo 2 blade 1045 3s 5200mah Naza Lite-M Radiolink AT9 And I notice this craft are heavy wobble when I rotate the craft (of course in air). I know when landing craft hitting its own propwash will cause that, but rotate direction I don think will. Two weeks ago, when I flying. It sudden wobble crash to ground ( i think only 2~3 meter from ground, testing flight) And after event I cant see / detect any wrong. So I make it air again, and it hovering 10~15 seconds normal, and it wobble crash again. I call that no/minor damage, and I fly and hover it last sunday about 15minute (got landing) it work well....quite strange(i set gain to all 100%,minor wobble still there) Any I got the idea to get few RCT800 arm from RCTimer make my Deadcat style to 800..will it work well? (not talking motor yet) Or I should get F550 center plate + 800 arm + 500~600kv 3s pre-solder motor + 13~16inch props? Thats my idea, please give the suggestion. thank you QUOTE(akecema @ Aug 31 2016, 04:08 PM) Merdeka fly at Taman Equine Flying Site My glider build Skysurfer 1400mm wingspan Turnigy 2200 KV (i feel i need more KV) ESC 40A Prop 6x4 Main battery 2200Mah 3s FPV battery 370Mah 3s Camera 700VTL VTX 600Mw 4 9g Servo Trying dogfight with my friend but only i use FPV |

QUOTE(akecema @ Sep 9 2016, 05:19 PM) bro li-ion has lower discharge rate than lipo..by a lot. it's usable with winged flyer, as the motor doesn't draw too much current too fast. won't work too well with rotor-ed flyer as these types of flyer draws a lot of current quickly to create lift and thrust at the same time. in summary:can explain about your li-ion battery how much max discharge your battery? i though wanna build 1 li-ion battery but i check my battery (xiaomi powerbank battery) only 1.5c max discharge planes/gliders/fixed wing: can work with li-ion if you are not too aggressive with the throttle heli/multi rotor: won't work too well. throttle will be sluggish at best. |

QUOTE(akecema @ Sep 9 2016, 05:35 PM) should work, but please get a reliable high discharge li-ion, for safety. samsung/panasonic/sony are good ones. not those lousy ultrafires. do note though that 3 piece of high discharge li-ions are more expensive than a 3-cell lipo. cost wise. you can easily get these high discharge li-ions in vape stores. 20-35A is pretty easy to find. SupermotoXL did share how he connects the batts together some pages back. that will help you get the general idea. from my own experience, both li-ion & lipo will get the motors to the same max speed(volt), but lipos will get you there quicker(C rating). also in load bearing circuits, lipos will be able to handle better load since C rate X capacity(in Ah) = max Amp. *see, i've learn a lot of electronics mumbo-jumbo from this hobby .

Video - My 72.6km flight with storm and heavy rains.
You guys wanna see mini UAV wing wing Z-84 in such extreme condition?. No other plane would able to survive this one! Flown with electronic flooded with rain water but manage to survive mother nature ultimate fury. Seeing is believing. I'm proud of my mini UAV plane. Yes the plane still alive today after 4 days of drying under the hot sun. Video: https://www.youtube.com/watch?v=7HmAk4bcoZc -------------------------------------------------------------------- QUOTE(akecema @ Sep 9 2016, 05:19 PM) bro My max discharge for Li-On pack which is now in 4s pack is 1.3A. Actually it can max up to 10A for 3 seconds but recommended for constant throttle is at 3A below. But for me i'd rather go lower for longer endurance. Li-On doesn't like punchy demand unlike Li-po.can explain about your li-ion battery how much max discharge your battery? i though wanna build 1 li-ion battery but i check my battery (xiaomi powerbank battery) only 1.5c max discharge This post has been edited by SupermotoXL: Sep 16 2016, 11:44 PM |

a question on GPS module. is there an orientation in which to physically install it?
i've managed to setup mine, getting a lock and everything, but do i need to pay attention to the physical orientation? |
