About this Plan

Scarab. Free flight power model. Designed for Amco .87 diesel power.

Direct submission to Outerzone.

Update 02/07/2018: Added a supplement file, Scarab plan redrawn from scratch in vector format, thanks to BryanGostlow.

Quote: "I've drawn up Scarab (Albert E Hatfull from Worcraft - 1949 - 35in span) and have had around ten 'kits' laser cut for friends. It is true to Albert's design but is seen to fly mostly with 2 or 3 channels, eg motor and rudder. I'm attaching a drawing in case you'd like to include it on your site. In addition, I've drawn it at 150% with some modest structural changes and had several 'kits' laser cut - they too fly well. Regards, Bryan"

Update 29/12/2018: Added printwood tracing file, thanks to rchopper56.

Quote: "Hi Steve and Mary, very pretty model so I could not resist tracing the print wood in CAD. Because this is in a sense a tracing, I had to make many assumptions. Although nice and clean, You may not want to use for I am sure there are errors but then, there were errors in the original. Some day I just may do a CAD drawing of this pretty model. That way, the enclosed PDF file could be corrected. Gene"

User comments

Recently built a Scarab to Hatful's original plan, but mod v slightly for modest increase in span as per Bryan's excellent drawings. With a RedFin 049 on board it disappears from view very rapidly! Had to get a tree surgeon into retrieve it last time. Strong, light aeroplane ... superb. The photo is my 44" span version ... not quite flightworthy! [more pics 007]

I see you've added my Scarab drawing to your archive - many thanks. Recently, to celebrate 70 years of the Scarab, three friends flew theirs at Impington http://www.impmac.co.uk/, all laser cut from the plan you've posted [more pics 008]. Look closely and there's a 1.5x Scarab and other Albert Hatfull designed models (and a couple of not so subtle references to his name). The Scarabs were built and flown by Alan Hunter, Tony Neal and Richard Staines (x2) - other models were by Alan Hunter

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.
