ok......... so...
thats the Tx, this thread is about Receiver packs.
I can swear Ive never seen a 11.1V pack smaller than a 6.6V LiFePO4 of greater capacity.
then theres the added complexity of the regulator (these devices are known to fail)
and unless its packaged in a large scale aerobatic or scale warbird requiring high torque digital servos; where's the benefit?
The "known to fail" response often used, is a bit specious.
Our servos are "known to fail", our engines are also "known to fail"... in fact anything in a plane is "known to fail".
Failure RATES for BECs and regulators when properly used are MUCH lower than what you are likely to see for an engine or servo, let alone a control surface.
Like anything else, you just have to use it correctly.
Were regulators so problematic, high end companies like PowerBox would never have the market they do.
Even the cheapie 9.00 BEC's have rather amazing resliliency. I've used dozens on an equal number of planes and have yet to see ONE fail in any way.
I've seen more "failures" with bad RX NiMH cells than I have with BECs.
