Hello Iam planning a pushing delta wing plane and wondering what methods anyone has on mounting this on planes? any ideas on how to mount on plane? any tips or suggestions on an engine mount would be great appreciated thanks
I strongly warn the users of this double engine ,not to use it with a single ESC supplying both coils !!!. Reason Why= At the start of running , at Lo RPM , each ESC manage it's coils switching according to a special soft ( when the un-used coil can't indicate any rotor position signal to the *-Processor ) so , two engines both can't have the same position , and the ESC signal just CAN'T drive the 2 engines = at Lo rpm it's an electric mess !! and mechanical as well when you try it !! Very bad in all case anyway!! So best thing to use this special and very interesting motor , is to use 2 cheap 20 A ESC . But much more efficient : mix the Th channels after Rx => I recommend the channel mixer HK Ref = SKU GW-V-Tail-J . You plugh the Throt channel on one entry / One Aux Ch (6 or 7 )on the other entry. And the 2 ESC on the 2 output. So you have throttle for the two motors , and the Aux Ch is used to trim the dissymetrical between the engines . Then , with yer own ears and eyes , you can find the exact synchro RPM ( very pleasant noise when they run synchro!!) Cheap and efficient , it's whant I use , since my magnets troubles . This devices allows to synchronize RPM overhead any kind of di-symetrical troubles ( magnets position after re sticking & so on )
You can also use 1 ESC but it will need to be at least 40amp a 50amp will be better I use one 40 amp esc on the CR23M Contra Rotating BL System1550kv turning 7x3.5 3 blade prop and everything work without any problem.

* Todd. If you use this motor on a tricopter you card must support Y6 programming and the giro on the card are pretty much compulsory but I guess it will not be impossible to make a device without giro stabilisation, good luck though it is going to be challenging to fly. Try the "Co Axial Contra Rotating Brushless motors" and REMEMBER THEY ARE 375WATT BUT MORE AROUND 100W with a gws 7x3.5 3 blade or gws 8x6 this motor are less then $20 :-)
I actually do and sorry but the HK quad support and X configuration for quad only.
Other board like the kkmulticopter (black board, red and blue are older version) can be purchased on ebay for really cheap. Remember to pick a usb dongle for the programming or at list for properly maintaining your device flying.
If you are lucky to find an open pilot board(openpilot is open source and not affialated to a business) just go for it this board is amazing and the Ground station control software is wicked. The other board I know that will do y6 are FY91Q the classic multikopter one and many other but I don't have all them here.
Ok,thx. The other configuration I was thinking of was a y3 config with the front two blades spinning in opposing directions, and run a contra system as the yaw, is this programmable on the boards? also, to get one of the front motors to run backwards, can I just switch the and - terminals around into the speed controller without damaging it, or is there a proper way to do it? thx
For the Y4copter configuration it is possible but I'm not to sure how you want to do it. You'll need one esc per motor and each esc connected to copter control board. To reverse the rotation of a brushless motor you simply switch around any of the 3 wires connected to the ESC. Doing all this from scratch is pretty difficult and you best choice will be a kkmulticopter/openpilot or a ardupilot (diydrones). The kkmulticopter is currently sold with the Y4 config it is completely possible to program it onto the other one too.
You can do it. I had a setting like this but with 40amp esc for the CR23M it worked fine but sometime the esc did seems to get confuse at throttle down to just a bit of throttle. The other things you have to consider is that you'll have 1 ESC and if something go wrong you might have no more plane. If you use one esc for your tricopter it will not work! because you need to be able to control the speed of each motor individually from the copter control board.

It was a bit of a gamble with this purchase as I had no idea how to mount this Motor due to its long length and mounting holes in-between the two motors...but I decided give it a try to have something different from jets, twins, flying boats etc. In end I installed it on my DZ500 using few 5mm spacers and long screws, it just installed in a flash actually and the power is immense I was glad I gave it a shot despite the low score reviews on the similar larger and smaller BL systems here but this was just right size for the DZ500 with 2 25amp esc, changed the props to 7*5 3 blades the escs hold up nicely and power is smooth
