Hobby King FPV250 with M4 FC

Postby Kisssys » Thu Nov 27, 2014 2:46 am

I am becoming fond of the 250 size copters to just play around with. This is my HK FPV250 with Emax 1806 motors. Runcam camera a 250 mw Fatshark TX. There is a Minumosd onboard but it's code not completely compatible. I had used it with a highly modified aq_mavlink and it worked well, I need to dig into it and get it to match all the changes we have made to mavlink over the last couple of years.

I'm using R432 with minor changes to Motor.c to use the Kiss 18A esc. Menno has posted the changes elsewhere on the forum. I've reduced the preload values a bit as the KISS esc is very fast and probably would be fine as is.

Go to about 2:15 and my daughter is flying it with no problems it's so stable. She's been practicing with a 120mm M4 quad I gave her a few months ago.

Cheers
Steve

Thanks for sharing. Very stable. That's a nice copter to fly around the house. :)

Cheers

Steve,

That's awesome stability and exactly how i would like my fpv.
Would the size support esc32v2? (I have 4 of them to spare and i would prefer not to buy more esc)
What camera & tx?
I hope the tx is fatshark compatible.

Do you use Goggles or OSD?

Yes, you could use esc32v2's. That is a RageCam camera I think and a Immersion TX which is Fatshark compatible.

I use the MinumOSD from readytoflyquads. They have a new Micro MinumOSD which I need to try, 15mm square.

I went through a several days of testing last year to figure out why my quad would suddenly go crazy. It turned out to be a bad Sony Effio camera zapping my GPS. If you have one you might see if it's the same chip set. It's got a great picture though.
