I'm sure this will be old news to many on here, but thought I'd make a few points about the radio gear I've assigned for the miniature Delphin. At the top of the picture we have two 5 gram servos, 9 gram servos are a bit cheaper, but would be too big for this model. Down from that we have a reversible brushless ESC from HK, nice little unit and cheap (about a fiver), rated at 10A, that's plenty, as the motor can only deliver 5A max. Next down we have a microgyros leveller, and below that a 4-channel Jeti receiver with pulse processing (cuts down on glitches). To the right of the RC is a 10 gram brushless outrunner. This is rated at about 40 watts, and just above that is a ten pence piece so you can get an idea of scale. Small stuff, but not the smallest equipment available by a long chalk. All this weighs about 40 grams, and a good chunk of that is in the wiring and plugs, so they are going to be trimmed back, and I plan to use copper clad 0.5mm epoxy glass sheet for the tech rack, and photoetch in the signal and power cables . This will tidy things up nicely too.
