I am reluctant to tell people what the should or should not do, I prefer to tell them what I do that works. They can copy me or not as they see fit.

For that size plane I just finished one, I have a single 2400mah Li-ion pack in it with a MPI miracle switch with integrated regulator. This is the setup that fails to the on position. No power box is needed at this size. For servos I'm trying out Hitec 985s, I was looking for a less expensive alternative that still has decent speed and centering. I have not flown this setup yet, so wait for the news reports. But I have tested all these components in other planes and they seem to work well.

If you feel you need a 4 cell lithium pack, I'd rather see two 2 cell packs and 2 regulators. I like the mpi switches and the MPI regulators, they are not expensive and I've never had one fail even in a 40% plane. This setup then gives you some redundancy for the regulators annd switches. I have never had this setup bring down a plane either.


I hope to fly this one, a 50cc Sukhoi with the TOC-53 engine, very soon, like maybe tomorrow.
