About this Plan

Yoga Dolphin. Radio control glider model, for 2 channel micro RC.

The original Keil Kraft Dolphin (oz1333) was a free flight model, designed by Albert Hatful in 1952. This here is a modern plan showing a redesigned alternate fuselage for the Dolphin, incorporating 2 channel RC, access hatch and other minor changes.

Note the original Dolphin wing is to be used. So this planfile does not include the wing.

Direct submission to Outerzone.

Quote: "I have always been a follower of Albert Hatful designs and to my mind he was a genius even at the age of 19 (Junior Sixty and more). In particular, the KK Dolphin, designed as a free flight model flew faultlessly.

We have now moved on, want more and have micro radio control. What I did not like so much about the Dolphin fuse was that it was very bulky and the frontage was similar to a Waco Hadrian troop carrier.

I felt that it could be so much streamlined into an even more 'Leaping Dolphin', the fuse length shortened, the width halved and still install 2 ch micro radio.

I was not happy with the wings just plonked on top. I wanted the wings to be integrated with the fuselage. With my pictures you will see there is no wing fairing from the back of cockpit to the wing LE. This is on purpose as I use the Dolphin wing to fit on other gliders.

The wing and tail plane are perfect design. The fuse was also perfect but I had other ideas in mind. So?......how dare I change an Albert Hatful design? I feel guilty, ill informed and a traitor. But I have dared. Who dares wins! Happy flying, Pete"

Like we said, quote: "Note the original Dolphin wing is to be used. So this planfile does not include the wing." Just take your time, read the information, and breathe.

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.
