Speed stuff

Here is a link to pictures of both a pan and a fiberglass top.  The pans were generally magnesium and formed the bottom half of the fuselage for C/L speed events.  The pan served two purposes: (1) it acted as a heat sink drawing out heat through the crankcase and (2) it provided a stiffener by supporting the full length of the mounting lugs on both sides of the engine.  While 1/2A engines did not flex too much, the crankcases of the larger ultra-high performance engines could distort.

Speed competitions are flat out scary.

Do a search for: control line speed planes
There are lots of pictures in the images section.

Fred, are the Tatone pans full and not half pans? I'm not fully understanding your description in terms of shorter. Are you referring to shorter than the Cox pans? In addition, the Cox pans are dark due to oxidation being magnesium. Are the Tatone pans cast aluminum and shiny? Some Tatone also used a cast marking within their pans to designate it's size. Does your pan share those markings? For obvious reasons, there's no questioning what a 1/2A pan is but there's a specific pan I've been in search of. I sent two cast pans out for welding a few years ago. The 1/2A pan was one which wasn't repairable, I never received it back so I have no pictures to show. Luckily my B pan was able to be welded and I'm currently using that now.

I’d like to say that Fred is one great individual to deal with!!!
