Hermione’s frame

If you want a super strong X8 compatible frame that’s large enough for every possible sensor, there’s only one out there that fits the bill.  And it fits it well, and then some.  It’s designed and hand-made in Poland at quadframe.com by Jakub Jewula.

The frame is carbon fiber throughout.  The arms are hinged to allow them to fold for transport, but lock into place amazingly sturdily for flight.  The kit comes complete with a simple but well designed power distribution tower, outer-plates for 5V power, WiFi and GPS as shown (or whatever you want to add) and various shelves for flight controllers, LiPo’s etc.  I love the way all the wiring for motors, power, GPS and WiFi can be fed down their tubes to protect them from blades during flight.

The standard legs aren’t strong enough for some of the catastrophic falls Hermione has had during her development, so I use these instead.

I have a few bits of build advice:

  • Don’t be scared to tighten the bolts as hard as possible for brackets attached to the CF tubes
  • Don’t bother with the bolt to join the CF arm to the shoulder socket joint, just use epoxy resin glue; it gives a better distributed, stronger connection, and hence significantly reduces the chance of damage on impacts by ensuring forces are passed through to the frame itself.
  • Apply a little grease to the shoulder joints so they can’t lock up if you over-tighten them.
  • Wrap some duct-tape at the ends of each arm where the motor bracket joins to prevent hard side impact pushing the motors down the arms.
  • Add these foam rubber balls to the end of the legs to try to absorb some of any impact landings.
  • If you want a cover, this salad bowl is a perfect fit, shown in a previous revision of her frame build:

Note that I was not paid for this advert and I paid full price for the frame.  I’ve written this post because the frame is simply the best DIY fold-able CF X8 frame available, period.
