RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)

The symptoms you describe (cutting out at high RPM) sound like what happens with to much voltage applied to the ignition (until it fails completely). Regulate it down to 5v or put it on a 4.8 pack and I'll betcha your problem goes away.
Been there done it.... got the t-shirt to prove it too!
I tried my DLE 20 on an A123 direct and had exactly the same symptoms. Regulated it down to 5v, no problem since.
