I bought a storm srd 280 v3. Looked great. They say they are tested. When armed this one would instantly want to flip. When that had been sorted. Reflash of fc i kept crashing it and blaming myself. Turns out it wasn't me not on any ocassion. It just falls out of the air like a Rock.
I took it apart and found 2 crushed wires. That wasn't the problem.
Turns out it is probably a sync issue. Ii was trying to solder ground wires to the escs because apparently they should be there. Problem is solder won't stick to the ground pads. Not on any of them. Weird is that.
I have also purchased a s rew kit. The are 2 piece screws that break under normal tightening. They charged me 36 dollars for that kit and it's rubbish.
I also had to order numerous arms because of its fall from the sky problem. The original arms bent. The ones I had to order snap. So a difference in carbon quality.
I initially emailed them and they said send it back at my expense. 100 dollars plus.
I emailed thier tech support and recieved no answer. Yet they say they have answered all emails... no they haven't.
This rtf package cost me 700 dollars and 0ver 300 in parts to replace all the broken bits.
Perhaps I got a lemon. Bit that don't explain he dodgy screws... who makes 2 piece alloy screws... it doesn't explain the unsolderable ground pad on the escs ot the shoddy carbon arms that snap. Totally unlike the original arms.
