H250 ZMR250 250mm Carbon Fiber Frame Kit RC Drone FPV Racing Multi Rotor
A part of the review has been auto-translated.
I posted here before, and stated it was Carbon Fibre. It seems that only the outer layers are CF, and in between is something like glass fibre. Still strong stuff, but not what it is advertised. You can test it with a multimeter, CF conducts electricity. I don't say all the frames are wrong, but there are alot of non full CF ones that get sold as full CF.
Two weeks between order and delivery (including a few backorder days). The product is quite fine : carbon quality and machining, complete kit and easy to build (in 30 mn). You even get two bolts and nut for spare. Nuts are all nylstop. Arms are 3.2mm and plates 1.5mm. Total weight 135g. Distance between : front motors= 202mm ; front and rear= 156mm ; front left and rear right= 255mm. Very good product for the price.
