Chrislea Super Ace (oz9058)
About this Plan
Chrislea Super Ace. Free flight scale model for electric with KP02 power unit. Scale is 1/12.
Quote: "It was at Little Rissington where I espied a lovely little scale 'Super Ace' taking to the skies and it certainly warranted a closer inspection. Dennis Reece was very modest about his creation, but it had all the attributes for good scale fun flying, not too large, electric powered for no fuss or mess and a dainty flight performance. As Dennis explained, the construction is straight forward and he has only concentrated on the fuselage building in the construction notes. So what are you waiting for? Get going on this model of an early post-war British design which deserved to be more successful than it was.
Incidentally, the full-size had a fairly unique control system, a genuine single stick arrangement. The control wheel could be turned left or right to actuate the ailerons, up and down for the elevators and moved sideways for rudder operation. For the basis of his drawings, Dennis used a small 3 view published in the Putnam 'British Civil Aircraft Since 1919' book.
Construction Notes. The basic box fuselage is constructed from 1/8 in sq balsa strip. Make two sides on top of each other and separate. Turn upside down on plan to construct box shape. I use card formers to ensure alignment especially at the 'pulled in nose'. Turn upright and odd top formers 1 to 8. Sheet in nose end using 1/16in sheet strips.
Add cabin side uprights taking care to use exact sizes to achieve correct wing incidence. These should be strengthened by facing inside with full length 1/32 x 1/8 in strips (top cross members should be displaced by 1/8 in to allow for this when constructing basic box). Add cabin top cross members. Make cabin roof using laminated 1/16 in cross-grained, cut out upper glazing holes and glue to top cabin cross pieces.
Make lower cabin piece also from laminated 1/16 sheet and fit to upper former S. Add all cabin details (cabin strut, dashboard and pilot, paint inner details white). Add rear decking strips - 1/16 in square.
Make wing centre section. Tongue is made from 3/32in sheet faced both sides with 1/64in ply (I use PVA for this) clamp for 48 hours. Cut out upper glazing..."

ScaleType: This (oz9058) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Chrislea_Super_Ace
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

User commentsI have just printed off the plan and note wing washout , can this be correct at 1 1/2in on each wing ? seems a lot to me

I think it's a typo that should have been "Build in ½ in washout in each wing panel". Somehow the word "in" got replaced with the number "1". On a ~16" long panel, with a chord of nearly 5.5", washout of ½" seems reasonable...

Had some interesting thoughts with ref the Chrislea Super Ace drawing, by Dennis Reece. The front undercarriage leg is shown suspended from nothing - with no details as to how it is supposed to be made. It needs a stop to prevent the leg from swinging forward against the tension of the band. There is no anchorage point shown for the pivots. Interesting though, any ideas?

Jack - I agree that the plan lacks the depth of detail you desire in regard to the front LG strut mounting. Few things can be less pleasurable than a build that is fraught with frustration. Don't let this potential problem deter you. One of the great joys of modeling is finding new ways of overcoming difficulties. In this case, I might suggest a couple of pieces of 1/8 sheet, running longitudinally, from F2B to F3B to serve as a mounting for the strut pivot. Alternatively, the illustrated design concept, utilizing a pivot and rubber band, could be abandoned and a much simpler design incorporating a co-axial coil spring could be employed. In this latter case, movement of the strut would be nearly vertical and the swinging action eliminated altogether. You needn't be a slave to the plan. Think of it as an underlying framework, a guide for your own creativity. Be inventive and have fun.

* 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.
