Point Five (oz5359)
About this Plan
Skyleada Point Five. Free flight sport model.
Quote: "This free flight model is very rare. I have not seen it anywhere on the web. I have built several and all flew great. Extremely easy to build and can be powered not only by point fives. Mine had Cox Babe Bee .049 and Cox TeeDee .020. A very classic and traditional free flight sports model designed by 'PK in 1952'. Best wishes. Eduardo"
Direct submission to Outerzone. Note the wing rib is missing, but could easily be enlarged as an approximation from the stab rib that is shown on the plan.
Update 02/03/2020: Added alternate version of the plan, thanks to Gnomelike. This includes a 'tentative' printwood sheet that's been extracted from the original plan scan drawing, and also shows ribs for the main wing that use a profile copied from the (existing) tailplane rib.
Quote: "Dear all at Outerzone, I must agree with Eduardo about the Skyleada Point Five model and thank him for uploading it. It's a lovely elegant and simple model, ideal as a first power job for beginners and folk like myself sport/Sunday flyers. It looks like the rudder was just cemented to the tailplane, I have added a central tailplane rib to the base of the rudder so the builder can choose between trimming the rudder and cementing it to the tailplane as before or as an alternative use the combined rudder and rib to give a stronger joint if they wish. The idea about enlarging from the stab rib was spot on as it matched up perfectly with the leading and trailing edge stock so credit where due! All the best, Gnomelike"

Have changed this listing to show Pete Kelsey as the designer (I'm assuming that's what the PK stands for). If I'm wrong, I'm sure someone will point it out :)SteveWMD - 02/03/2020
Hi Steve, after more than 60 years, I finally find who is PK although I have never heard this name before. Are there more designs by this chap?
Concerning the new version of the plan, so nice that the parts are separately included. However, please check the wood grain on the rudder. It is wrongly placed. Grain should be towards the longest part. I am presently building another Point Five but it will have a miniature servo since I am no longer fit to run after this fantastic model throughout our entire countryside. I remember my youth when I built 4 and lost them all. Those were the days!!
This model was also a locally made kit and called the "Fenix" (Phoenix in Spanish). It sold like hotcakes and it will be rekitted once again for electric power with or without RC.
Best wishes!!

Pete Kelsey was the designer of the Skyleada Zipper (oz9538) and searching online for him (and Skyleada) finds the Clarion SAM 1066 newletter at http://www.sam1066.org/nc0414.pdf which says he worked for Skyleada as a designer/draughtsman from 1947 to 1953. Also that he wrote 'The Skyleada Story' which appeared in SAM35 Yearbook No. 12.

Either Paul Plecan copied from Peter Kelsey or the other way around. Just check Plecan's Hummingbird (oz110). Both are amazingly similar. It would be interesting to find out who copied from whom because the similarities of these two models are amazing. I refuse to believe it was just a coincidence, although it could be, but difficult to believe.

This the Paul Plecan 'Hummingbird', redrawn and renamed.

You mean Plecan copied from Kelsey or the other way around.

I may make one of these but without measuring, it does seem to have a huge amount of wing incidence. Does this manifest itself during trimming?
bill dennis - 16/02/2025
Hi Bill, I think PK had a smile and a chuckle drawing this one! Two obvious choices:
- reduce the wing incidence by, say, 3°. Best to reduce the tailplane incidence by 3° to keep the decalage the same. Downthrust also seems to be missing, so 3° here would be about right. OR
- build to the plan, and lower the nose about 3° before launching!

Thanks Roger. I've had reports that it flies well so I'll stick to the plan, even if it does fly like a Whitley!

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.
