It all started from something small



2KG Huh?? You sure ?? and NO , these motors wont be able to lift it .

MY quad weighs approx 1.6KG ( with 5000mAh LiPO and the metal mods i added.

Used 2836 motors with 1pprox 1.2KG thrust per motor, my quad lifts at around 60% throttle

roughly calculated weight ( coz don't have Weighing Scale ) and it weight around 1.7kg ( i take 300g margin for zip ties etc.. and also take 10 to 20g more than the real weight of each item )
any suggestion what to do now.. should i buy 11X47 props ( it gives 830g thrust with 11X47 and 3s or 950g with 1045 and 4s battery)
and i don't think multistar 2212 920kv motor gives more thrust more than 700-800g with 1045 and 3s battery..

you can even try sunnysky  980kv motors, they produce same thrust as of multistar. there is video of testing both the motors over youtube, sadly I cannot post the link right now as am using a cell phone to send this msg.

if u want to invest a lill more and make the whole thing a gem, u can try multistar motors below 500kv. they ll give you enough thrust and also a great flight time. moreover instead of going with a 4000 battery you can implement laptop battery. if you play around with it, n do some manual work, they ll give a very decent flight time plus less weight.

around 750 to 800 max with a 1047 prop. if you are tight with budget, then you can try laptop battery it really works fine. recently an rc india member has tried it and was getting more than 20 mins of flight time.you can contact him for more technical details. I don't remember his name.

Most of the dji arms available are clones.  RCMUMBAI does stock originals,  but I would suggest you stay with the CF tubes because if you plan to take video, they are better at absorbing vibrations.

Don't use multistar 2212 920.  Go for sunnysky instead as it has much better bearings 2212 980(900gm thrust on 1045/3s). If Buying new motors.

As for eMax 2216 800 which u already have , it's larger and lower kv,  use 11/12 inch props for max thrust on 3s. And 10inch for 4s. More than a kg thrust. 1045/4s is good choice for this.

2216 and 2836 are same size, some follow internal stator size, some brands use external size for naminG. Smiley

yes cf tubes are batter. but it is very difficult to balance motors on cylindrical tubes.( i tried with spirit level but not accurate..)
