Plan file details
Sterling Royal Coachman. Radio control sport trainer model for .09 to .15 power.
Quote: "Our prototype balanced slightly aft of the point shown on the plans. With the Annco servos we added three dead peacells to the battery compartment for ballast. With the light additional weight of the Royal MK multi servos, two of these were removed.
If you have built the Royal Coachman according to plans, you will have no difficulty with initial flights. Use a 7x4 prop on the Cox .09 and an 8x4 on the .15. If your landing gear tracks straight and true, the Coachman will lift off with a slight tap of elevator in about fifty feet. As mentioned earlier in the article, flying this model with an .09 is simplicity itself - it is docile, yet will perform simple, basic maneuvers with six channel gear - an excellent trainer and sport ship for the Sunday flier. But add a .15 and you've got a fast moving ship that's quite a handful.
We hope you like ease of construction and the many hours of flying pleasure you'll get from the Royal Coachman. "
Quote: "Hey there, here is a companion to your RCM Royal Coachman (oz1302)
plan. This is a plan I just found at Hobby Warehouse in Richfield, MN which the shop owner kindly gave to me for this purpose. This Sterling kit plan seems to include the RCM article on it. Sorry about all the notes and sketches on it, but at least it will make it less than desirable to the e-bay resellers. The plan was in quite a sorry state, and please note the error right down the middle of the fuselage layout. The plan had been taped back together rather badly but its too fragile to fix. Dave"

Update 05/03/2018: Replaced this plan with a cleaned up version, thanks to rchopper56.
Quote: "Hi Steve and Mary, I spent some time yesterday cleaning this drawing. It is a typical kit drawing in that it is incomplete, missing some info for the top view but no problem for an experienced modeler, you just know its width from the back of the wing to the nose.
The drawing itself has had a lot of 'travel' and may not be a scan of the original kit supplied drawing. I contacted Dave to be sure if the hand sketches that were removed was OK with him. Gene"
