I rwally am suprised by graupner..for being german and costing more they are off by a bit. I have a set of folders for my zephyr. I have access to scales at work that can measure a diff of 0.0001 gms. One of the folding props was off by .1 gms which is a lot considering the rpms.

I noticed this too so i rolled the stock shaft on a sheet of glass AND what do you know? Thete was a slight bend in it. So i use another trick. One that is suggested by topflite. Use the gp fingertip balancer. The shaft is only 2-3one inches , hardened and the cones thread on.

I want to know if i am going about this the right way. I have a topflite magnetic balancer and graupner 9x5 eprops. I am TRYING to balance them. When on the balancer i work on getting the props level using tape. Then once they are holding level i move to balancing the hub. By this point i...

thats what I thought would happen !

whats your auw and how long have you been flying it at this weight ?

Adarsh...yeah the stock auw is 2400gms. Of course this may be based on the stock DJi crap props...How are the motors running with the 10" Graupners...i thought you couldn;t go that high on 4s...I have the 9" ones and am wondering I maybe need the 10s. What else you got dangling on that with 10"...

the earth has a true north and a magnetic north. magnetic north is what compasses are sensitive to. depending on where you are on the continent (or world for that matter) you will have to make corrections for variations in the earths magnetic field. you may find that you may have to offset the...

I dont think the naza has a commercially available gps data download facility. I am sure they have one at the factory. as to the rest I have nothing to add.

my lipo is under the bottom plate Under one side of the part that is long. On the other side across from lipo is my go pro. Also under bottom plate.

Boris. I have a question. I watched the video and tried to relate it to the f450. Where am I going to hold it ? in his video what doesnt make sense is where he holds it. Where he puts his finger would naturally make it top heavy. Shouldn't he find the exact center and then go out from there on Z...

ja will do. danke
