I have been looking at the types of faults people are experiencing with my controllers and they seem to fall into three groups.
1 Wires breaking off where they are soldered to the board this is often made worse by bad soldering when re soldered by customers causing shorts.
2 Connecting to the battery the wrong way round.
3 Motor drive failures sometimes caused by shorting to chassis or other motor but sometime unexplained.
4 Further in units where I have to modify the receiver and hard solder it to the controller it is difficult to determine which part is faulty and anyway the receiver warrenty is already null and void.
To try and combat these while designing a board to fit the new DSM2 compatible receiver from HobbyKing
http://www.hobbycity.com/hobbycity/stor ... duct=11972 I have made some changes.
1 First all the flying leads from the controller board are on a 7way crimped JST socket that plugs into a board mounted plug.
2 The two power leads are fitted with the red type JST that plugs into the socket which seems to be standard on Lithium packs these days.
3 This board has 2 motor drive chips increasing the drive from 1.2A to 2.4A per motor.
4 The receiver is unmodified and plugs into the controller board.
There is still quite a bit of testing to do but I have just completed the first prototype unit.
Controller with receiver removed (6.9gms without Rec 9.4gms with)

Controller with receiver fitted and 150mm flying leads plugged in. (13.6 gms)

As above with servo plugged in.

The idea is that this will phase out all the Spektrum compatible ones like the B60, B61, B63 options.
