FPV250 w/ Flip 2.0 FC

Here are some pictures of my FPV250. I am looking forward to doing some acro flying with it. I decided not to go with the Mini APM. I will save it for a better frame.

Just a thought.

Holy crap that's a genius idea!!! I've been racking my brain to figure out a way to stay this thing securely to my postage scale lol. Thanks a bunch!

Another thought.............I kind of forgot I was posting to a hobby grade quad thread, I do a lot with the super minis with soldered in brushed motors. If you have bullet connectors easily accessible on your brushless 250, you could just change rotation of your motors by switching 2 wires on each ESC and not even need to loosen a rotor blade nut.

Yeah that won't work, and you should know why.

Yup sorry
in a hurry and missed a thought, and again thinking more of my baby brushed quads than what I should be thinking about in this thread. The airfoils=lift need to be upside down AND reversed to work as we are speaking of for best test of downforce using this method.

Either would be a good choice. I have both, and other than the 2204 being larger and torquier, one thing I would say is that the EMAX motors are more well-made. (not to say that the DYS are junk, they're not!)

Also, are you aware that EMAX also makes an 1806 that is 2300kv?

Any three of those would be a good choice, but if you asked me which ones I'd go for if they were all the same price, it'd be the EMAX 2204's.

I have an idea that could help with the FPV FFF tilted motor solutions. Could you just mount the front two motors up-side down under the motor mounts, and switch the propellors. It would not tilt the motors, but still tilt the frame to a certain degree. Or would this create more problems?

To me, it seems it would require tilted motors in addition to lowered front and raised rear motors in order to truly level to frame for FFF and not have the rear props in the prop wash of the front.

A VERY ROUGH drawing. It wold most certainly look odd at hover with the sagging rear end.

DIATONE Frame Kit, Affordable Smart Choice

I bought the FPV250LH Low Hung Clean-and-Dirty kit and it came with 4 of these adapters. And I really like them and would love to use them, but I can't figure out the best way to attach them to the arms. They didn't come with any screws that fit like those in the picture. I tried using zip ties through the three holes around the edge, but discovered I couldn't put the landing gear on if I used all three holes and the adapter sits sideways and can wiggle if I use only two holes.

I've ditched them for now, but would really prefer to use them. What size screws are those?

@DucknDive, thanks for the complement and yes this was taken with a mobius (lens-b ). stock PID's on the naze32 is spot on, no need to modify except for the looptime which I used 2500.

Some more videos on learning rate mode on the naze32:
