I have about 15 engines. 5 or 6 glow engines and the rest are gassers.

There are guys in this hobby who have litterally HUNDREDS of engines. I think a lot of those guys who have that many engines would be considered collectors at that point. Still yet, there are guys who have 30 or 40 engines in their inventory that they swap from plane too plane and use regularly.

Too many engines? No such thing. Thats like asking a woman if she has too many shoes, or too many bras.
