elossam you are flying your bird in manual up to now ? Thanks Red for the diagram could have thought about looking at that on the webpage :)

japp no problem to fly without the GPS plugged in did it several times already !

But the thought it not a bed idea, have you found out which pins are necessary for flashing ? Maybe good idea anyways to lay them out and do a servo plug male female solution to the usb board to flash them. I have the same issue that i have to disassemble a couple parts to safely get the...

Im going to be start using these. They are about 100g lighter than the Zippy 5s 8000 http://www.hobbyking.com/hobbyking/store/%5F%5F18209%5F%5FTurnigy%5Fnano%5Ftech%5F8000mAh%5F5S%5F25%5F50C%5FLipo%5FPack.html Never had a problem with the nano techs Boris

I am actually really tempted to buy one and try it out and open it up and check out the components. We will be even more worried if they bring out a 600$ full featured with gps version :)

Sorry if its an old hat, but check out the 4th foto looks like a DJI Naza with different packaging. Anybody know anything about that ? http://www.himodel.com/helicopters/BUMBLE_BEE_Four-rotor_Aircraft_Quadcopter_Folding_design_ARF.html Boris

nisouck not quite sure what you are getting at, but since we all already had power surge issues i think a mechanical problem can be rules out Boris

Well the prop/size combo and power surges we think is related to the WKM Herkules combo at the moment. Concerning WKM in general no matter which ESCs you use, many have gotten better results and a more stable flight behavior with smaller props. 14 seems to be to heavy for the WKM setup to...

That the answer: So for an Hexa no problem with a Octo in certain situations a maybe problem. Boris 100A for a short burst should be OK. Buut, if you're really dealing with these kind of current - it might be better to simply use ex. 12AWG wire and make a power spider with connections for...

I just wrote the guy behind it lets see what he says.

Hi Andreas you guys tell me when you have time ( will do that over email) and i will come down to Regensburg. Have a big collection of props by now so we can test it with all different combos. I also had the surges on my CX Quad with AXI 2217/20, than again with the QCs/KWs I didnt. Boris

and i think the sruges are more bound to the weight of the props. If you remember you had the surges with the 12 3.8 APC which are arround 16 -18 grams i think. The CF MK 12 3.8 are a copy of those with the difference that they only weigh 11 grams

nope havent tried them yet still on the ground with mine. For me personal I just know the lighter the props the better for the WKM, so 11 grams CF 12 x 3.8 and the graupner gave me the best results. I am also going to try the 12 x 4.5 CF from the MK shop although the price really hurts !!!

I really do hope Andreas and Sebastian also test with bigger props. Knowing that sebastian is also a friend of Graupners i have my worries. It really seems to be the combo with bigger props and WKM herkules may FW on or off cant say yet. Just remembered this with the 14 x 4 on. Right at the...

Guys i dont get it. I have the Herks on the CX with WKM, KW motors more or less the same specs as the QCs, 12 3.8 CF props 11 gram Herks set to 18 DEG FW ON, and nothing no surges ? Before with the AXIs the smaller one i had the issue. The more I test and try to figure it out the less i can...

But there seem to be some truth to the fact that the WKM works bettter on quads when it comes to wind. The Fan is on full blast and the bird is in ground effect some of the time and still no visible movement on the frame. Lets see next we a cam on how it looks.

amazing stuff Juz !!! Boris

The KW motors MK shop 12 x 3.8 props combo seems to make sense for the CX ! Boris

Sorry about the bad quality, but i must say i am impressed by the WKM performance and the test i tried here. Hope soon i can take it to a real outside test with the same setup. Fan Test :) Boris
