   Yes, here's another, though I haven't built one for a couple of years,
while moving to a new house and building shop.  I build all types of flying
scale, as well as shelf scale.
 
   Since no one else has answered the question on what are they, I'll take
a crack.  Peanut scale models are small flying models, usually flown during
indoor meets (although some contests do feature outdoor peanut).  While
there are several rules, the main one is that the wingspan must not exceed
13 inches.  Pistachio are smaller, but I don't remember the exact size,
since I haven't built one yet.  Peanut is hard enough for me.
