Crusader (oz11902)
About this Plan
Mercury Crusader. Control line stunt model. Wingspan 56 in, wing area 628 sq in, for .35 engines.
Note the original Mercury Crusader was designed by Bill Morley (circa 1961). This here is a later plan, drawn up by Tony Johnson.
Quote: "Hi Mary/Steve, attached are plans I did for myself to build an accurate Mercury Crusader. The information used came from the four models I built for myself since 1965, the plan sold by Tom Dixon and an anonymous drawing of the kit component parts. I enclose also the original kit instructions and my own drawings of the airfoil sections incorporating construction tabs. It is intended my drawing is used in conjunction with the original kit info and although I have incorporated several mods to the front of the fuselage and show a built up wing trailing edge it remains Classic legal."

Attached some shots of my own Crusader, built from Mercury kit plans and converted to R/C [more pics 004-006].RFJ - 20/01/2020
Hello- would you by chance have the email details of Tony Johnstone the person responsibLe for re-drawing this Crusador plan OZ11902, I want to send a message of sincere thanks for doing so

Don't have that to hand right now, no. Maybe TonyJ will see this and we can put you in touch that way.

Dear Mary, I have attached a photo [pic 008] of my Mercury Crusador control line stunt model built from the Mercury kit circa 1971. This was the last control line aeroplane I built. The model was powered by a Merco 29 RC glow plug engine which, having an RC carburettor, meant I had to adjust the position of the fuel tank to match the location of the carburettor spray bar. The model was finished in heavy weight tissue shrunk with clear dope and finished with a sprayed colour dope finish and polyurethane varnish. The thing that struck me with this model was the pull on the lines compared to the smaller diesel engine powered models I had flown previously. At that time, I had not learnt to fly the full aerobatic schedule, but I could fly sustained inverted, inside and outside loops and figure eights. Kind regards,

In about 1970, I built a Crusader from the Mercury kit. The kit wood was a bit heavy and the finished model, with an Enya .29, weighed in at a shocking 52 ounces. Even so, the powerful Enya hauled it round well on 56' lines. I keep meaning to build another with lighter wood and certain structural modifications aimed at reducing the weight still further: if it comes out at 40 oz. or less, my OS .25FP-S ought to fly it well.

Hello Steve and Mary. Seeing the latest on the Mercury Crusader model (oz11902) prompted me to locate shots taken in the early 1960s of my model of it, built from the original kit [main pic]. My future wife Kath in the monochrome shot [pic 009] is holding the freshly completed Crusader in the kit colour scheme. The field I flew it's maiden flight in had tufts of grass upon it, of which I knew not in my impatient race to see how it flew. The lines caught and in it came narrowly missing me. That old Merco 35 still had plenty of punch to haul it off the ground with total authority, despite having run for many hours on other models in the air. As you can probably tell from the happy shot with me holding the wreckage up for all to see [pic 010], I wasn't unduly perturbed, well, I was still in my teens! I'm now building a new one from your plans! See attachments for your perusal of the 1963 Crusader.
All the best from Kath and me, cheers,

Notes
* 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.
Scaling
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.
