They appear a good choice. In my case I think with a total weight of 11kg the 14x8 prop turns to slow and the copter will fly sluggish. Not good for windy conditions. Maybe 14x5/14x4 would be better!
Very good point. I was curious about the bite it the 14x8s and if it is a bit much. I was also wondering about the 600kv rating with a heavy setup but then I saw the video below that helped me some. Their AUW is 9kg with 5.25 minute flight time. I wonder if ithey could squeeze more time with a lower pitch prop? how hot are your Tiger motors after a 5-6 min run?
Not sure if they actually fit the cs motor mount. Shouldn't be too difficult to make them fit in some way.
Anyone know when the Herc III will be available? For the Herc II boards. I see they are just for quads.. can you link two together to run as an octo? Also it looks to already have I2C support. Isthat what you are using? Thanks! josh
Hercules III looks to be built the same way, you just need to use two boards pancaked. From all the videos being uploaded, I would say it should be available very soon. Yes, 12c support. This is the board we're holding out for. Unless FF has something up their sleeve.
These motors look the same http://shop.jet-1a.com/product_info...=2268&osCsid=3dd9c6e92179842be967ed10a997d93d
Ha, the exact same motor. A whole lotta rebranding goin' on i'd pick the KW because they're all black, even though they are a bit more. I do wish the kv was a little higher, like in the range of 650kv. I'm now thinking a 14x7 or 15x6 prop would be a great deal of thrust on the kw10. These two will be my 1st selections.
Like this one? MT3515-9 KV:650 http://www.rctigermotor.com/show.php?contentid=161 Better with my old 13x5 props
This is better @ 650/600kv http://www.rctigermotor.com/show.php?contentid=133 Btw motor images are old > all tiger motors are black
Decisions decisions. We've been long time Axi users so it's going to be very difficult to switch over to another brand. Never had any motor issues using Axi over the years. I just wish Axi produced 6s capable motors in the 2826 series. Still seriously considering the Axi 2826/12 @ 760kv on 5s swinging a 14x4.7 or 14x6 prop. That's a beast of a setup but I really had hoped to end up at 6s.
I already seen people fly with 6s on the Axi 2826/12 with 13x6.5 Carbon props (with 10-12kg). They also tested the Graupner 14x8 but the Axi really got hot. 6s only makes sense with 14x8 or larger props and kv's lower then 600. The hover point (at full load) needs to be around 50-55 > 45-50% otherwise it's difficult to keep altitude. unless u are using dji in ati mode. With my current system the hover point at full load (10.6kg) is 35-40% flying with MK is a bit difficult. No easy choice! i know.... Btw it appears that the Kopterworx guys are mounting the kv10 on a CS frame> https://www.facebook.com/Kopterworx?fref=ts EDIT ideal hover point is 45-50% on the given altitude
Interesting, do you know if the Axi 2826/12 ran ok on 6s with 13x6.5, did they get really hot with that prop? I know that motor is only rated for 5s. Do you know the flight times they were getting? My first choice was that motor on 5s with a 14" prop. My max AUW will be approx 9.5-10KG
Or the axi 4120 line with 15x5" props on 6s. Even though that motor weighs a ton I think a lot of people are getting good results. Then you think about traveling by air with all those 6s lipos. 4s is a pain and we usually pack 10 sets (20 total)
The higher voltage does not kill the motor, Rpm or amp do. 2826/12 and 5s works great on 13/14" (max14x5) 6s needs 12/13 (max13x6.5) don't know the motor temps. No reason for 6s > to high Kv > 760 4120 are far to heavy for a copter under 12kg, mt3515 650kv <12kg, Kv10 <12kg, 2826/12 <11kg
I just decided that i'm not spending loads of money anymore 'testing' configs. I have boxes full of unused components because of this. I'm going to let the pros do the legwork. There are quite a few new big lift configs floating around but TBO I'd feel more secure with a setup coming from a guy that has a long history of doing quality AV work. Tabb's not the type of chap that'll rush a product to market just to make a buck. I get the feeling that this big lift setup will be the answer.
