About this Plan

Whizard. Radio control sport model. Uses the ACE foam wing, so no wing ribs or construction shown.

Also kitted by ACE R/C, see advert from June 1974 AAM [pic 005].

Quote: "The 'Whizard' is the direct descendant of a long line of ancestors including the Whiz Kid (oz8493) from RCM 12/66 and Ace's .02 powered Dick's Dream (oz5747). From them it has inherited its construction method and much of its general appearance and stability but there the family resemblance ends. Although it is a reasonably docile performer on an .049 Golden Bee with prop installed backwards and Ace single channel pulse rudder control, when fitted with a Cox .049 or .051 T.D. and a light weight two channel rig, it is instantly transformed into something else and the 'something else' is DEFINITELY NOT FOR BEGINNERS! It is fast and responsive, and Right Now! Capabilities include loops (inside or outside) Cuban 8's, wild snap rolls, almost axial rolls and a really frantic spin rale. Throw in an experienced flyer and it goes inverted with ease. Perhaps its most surprising characteristic is its wide speed envelope with flat out velocities in the 50+ mph range, coupled with a slow gentle glide that is something to behold.

Wheel landings or 3 pointers are a delight, for the long stiff gear handles grass fields with no tendency to nose over. Hand launching is the easy way to go but if regular take offs are your thing be sure to add a fairly large steerable tail wheel and consider bending the landing gear back nearer the CG.

All of the foregoing is true yet somehow does not begin to convey what this small one is really all about and you can't really know that until you've tried it. The hard to describe element is joy. The joy that comes from experiencing the snappy response of a really groovy plane, knowing that it does not represent a winter's work or a monthly car payment. The net result is that the several flyers in our area who have gone this route have found themselves flying with an 'elan' they did not know they possessed..."

Update 28/02/2017: added article, thanks to RFJ.

Note this plan used the Ace Foam wing. For a plan showing how to construct a replacement wing in balsa (both tapered and straight-chord) see Ace Foam Wing (oz8557) thanks to AndyKunz.

Update 09/11/2020: Added kit review from MAN, January 1975, thanks to RFJ.

The formers are complete on this plan. There are no ribs or wing layout as the plane used a constant chord ace foam wing.

Actual wingspan is 40-3/4" as the Whizard uses one Ace constant chord wing plus 5-3/4" of a second wing for the center section. The plan says 40-3/4" but the small diagram measurements add up to 39-3/4", so take your pick. Had one back int '70s with an Ace pulse system and a Cox Golden Bee.

Thanks. Ok have now set wingspan field for this one as 41in, that's rounded up to the nearest inch.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
