Converted Pattern Bat
« on: October 23, 2007, 02:46:51 PM »
I was given a R/C Pattern Bat (partially finshed) by a good friend. He thought it could be converted to C/L fairly easy. I'm to the point where I need to decide about a powerplant. The motor mounts are sized to where a OS 15 LAS I have will fit. As a R/C plane these were flown with .11 size engines. My question is, at 366 sq. in. is this to big or heavy for a .15? The plans show a  2 oz. tank,plenty of room for that. For the bellcrank mount I used two 1/4" hardwood square dowels and ply, this ties the engine mount and tail assembly together. I'm trying not to and any more weight to the structure than I have to. I do have a spare OS .25 LAS I could use . This plane is for sport flying only. I know several old combat flyers that like to tear up the skies, but usually only fly several minutes at a time.
Any advice would be helpful.

In my opinion that should work great on 52 foot .012 lines.  Let us know how it goes.  DOC Holliday

366 sq. in. is actually a little small by modern standards for a .15. The important thing is - what does it weigh?

I haven't had a chance to finish the airframe, just started a new job. Most of it was completed when I inherited it. I plan on using ultra cote and very little paint on the engine mount and tail. will post once i get it covered and painted.

I haven't got back in the shop since our deer hunting season started. For those interested we did put three bucks in the freezer. My father( age 68) is still on top of his game,shot a nice 11 pointer that we could hardly lift into his KAW mule. Probably back to work on the Bat after Christmas.

I have one of those kits and have thought a few times of converting it. Another one of those things for 'one day'
