True, the LT-40 is an excellent trainer - perhaps the best one out there today. It is a .40 size (or ideally a .46 size) glow trainer. Nothing wrong with that unless you don't want all the field accessories to support glow engine operation.

Sig makes an EP-42 electric version of the Kadet albeit smaller than the LT-40 and is also a taildragger. I think they also make an electric version of the LT-40 ARF/RTF.
