I bit the bullet and ordered one of these. I have used Emcotec equipment in the past and it is extremely well made. I ordered the 120A version, but they sent the 60A instead. When I asked about using it in an F3A plane they said that many European pilots use the 60A in F3A planes, so I am inclined to give it a try. The 120A burst should cover it for me.

It is much smaller than an ESC, at least an ESC used in a pattern plane. It is 1.2 inches wide and 1.5 inches long. It is 0.3 inches high. So we'll see how it works. I very much like the idea of being able to install my packs and have the power to the ESC dead until I turn it on.

Sadly I did not know that HKM-USA sold these. I did not have a great ordering experience with Emcotec Germany this time out (been great in the past). I've sent HKM-USA an email to see what his stock status is and I'll let you know when I get an answer.
