Quote: "FELIX - A tribute to Albert Hatfull. Build this charming mini-vintage pylon model, from the late 30s.

Albert Hatfull, famed designer of so many Keil Kraft kits, was born in September 1926 in North London. He began aeromodelling at the age of nine, being fascinated by all aspects of the world of aircraft. This led to building a series of flying scale kits, mainly by Megow and Lindberg. This early experience gave him the love of flying scale models which has remained with him ever since.

He and friends formed a model club with flying sessions on the local Lea Marshes. Albert built an impressive number of models including 'Pacific Ace', 'Clodhopper',' Burd Korda' and 'Cloudcraft Commander'. The club eventually merged with the famous Northern Heights MAC and by the end of 1939 Albert was flying his own designs, one of which was 'Felix'.

During WWII he was commissioned by Eddie Keil to design a glider kit. Albert produced the Invader (oz418) - a KK favourite ever since. This was the beginning of an association which was to last throughout the Forties and Fifties. It produced such classics as the Junior 60 (oz9995), the Senator (oz472), the Orion (oz8832) - almost all the range of small flying scale kits, and many others. He also designed large flying scale models. A range of ten was intended but only three were produced.These are now being demon-strated with great skill by Doug McHard. Aside from his Keil Kraft work, Albert designed kits for Elite and Worcraft. He also produced plans for Aeromodeller and Model Aircraft including the President (oz293) and Penny Rocket (oz2877).

Today, Albert and his wife Jean live in quiet retirement in East Anglia. He does not enjoy the best of health but is cheerful, nevertheless. If asked, he will express mild astonishment that so many of his designs are still built and flown, but will say that he is very pleased if they have brought pleasure to a lot of fellow enthusiasts. That is what they were intended for. Thanks, Albert.

BUILDING FELIX - BY BILL MORLEY: I first saw a photograph of the 'Felix' in Albert Hatfull's scrapbooks and was taken with its unusual design for a small model. Unknown to me, Albert set about re-creating 'Felix' from the photo and from memory. Some months later, a plan copy arrived on my doormat and, upon seeing it, it became an immediate 'must build'.

Despite its streamlined fuselage, the 'Felix' is easy to build. The stringers should be fairly hard and should be added alternately on left and right sides to avoid a banana shaped fuselage. The undercarriage should be installed after adding the central stringers and the two above them. On Albert's original, the U/C was sewn in, but I fixed mine in with 1/16 sheet balsa, as per the Korda Wakefield. The pylon, being laminated, can be made of the very softest quarter-grain balsa.

Felix is a cracking flyer and very easy to trim - mine flew straight from my hand, needing only 1/64 in down-thrust to complete the trimming. If you wish it, 'Felix' will give you contest performance - mine goes straight up and, unlike many small models, actually GLIDES!. Have fun."

Hi. This photo of the flying Felix [main model pic] was taken by Roman Groener at the rubber engine meeting in Holziken, Switzerland.

There's some video of the Felix in flight at https://www.youtube.com/watch?v=rwmojC4wSfg

Good afternoon Mary, Steve. Happy New Year. Some photos of the Albert Hatfull Felix [main pic, 007-009]. A lovely, lightweight (48gms with rubber) model. Just right for my small meadow on a calm summer evening. Thanks for all your hard work, it is appreciated. Very best regards,

Hi Mary and Steve, Here’s a photo of my recently finished Felix [pic 010] awaiting some good weather for its first flight. Regards,

Dear Mary and Steve, Please find attached a couple of photos of my Felix [pics 011, 012] which I have recently completed. Many thanks to Andreas Koch for his advice with this build along the way. Thanks for Outerzone, it is a wonderful resource! Best Wishes,

Hi Mary , Steve . Not sure if it is worth adding to the plan info for oz1639 Felix and oz12985 Millennium Moth that laser cut parts are available from Mr David Wilson at lasercuts04@yahoo.com
My poor paws are to stiff with arthritis to cut stringer notches in 1/16" sheet so I got David to trace the sheet parts and cut them for me . As they are now saved in his computer they only need cutting out and will be cheaper than I paid. The wood is of excellent quality and the service is quite fast. He can trace and cut most plans but obviously the fit of the parts depends on the accuracy of the plans. Price will vary with complexity of parts.
I think they are good value for folk that have trouble cutting intricate parts . Note these are sheet wood parts only , not kits . Parts set for Felix shown as supplied with foam rubber packing above and below [see pic 013] . His quoted prices include postage and secure packing . He is currently cutting some parts sets to make up lightweight ply and balsa disc ff wheels in sizes I need . A very handy chap . Polite and efficient.
Thanks again.

Hi Mary, Even though there are already some excellent examples of the Felix on your website, I thought I would share my take on this model [pics 014-016]. I took advantage of the translucent nature of tissue and placed graphics on the inside of the airframe. Thanks!

Lovely work. I think Mondrian would approve!

* 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.
