First thing I noticed about the ignition is that it is RCexl to wit I've always found them very reliable.

An aside from the ignition, I'm building up a Seagull Funfly3D (46-55) and was happy to discover that indeed the evolution 10cc is a drop in for a .46 engine. I had zero problems installing it in the Funfly 3D. An ordered fuel tank has not arrived yet but based on the advertised dimensions for the 8oz tank, it and the ignition will both fit fine in the fuel tank area.
