Possibly the best trainer ever (IMHO)

Years ago I was involved with designing kites with a company called Go Fly a Kite. This company was bought by Jakks Pacific, a large toy company. I wanted to work on a RC plane that they called the XPV. Extreme Performance Vehicle. They wanted a plane that would fly off land or water. The inspiration was from the Hydrofoam plane that was such a rage years ago. I knew that that particular design would last about 10 seconds in the hands of a 10 year old, and thought I could make a plane that was more appropriate for a new young flyer. The design I created was never used by the company, but to this day I have never seen a plane that was easier to fly, or more durable. It had the very unique characteristic of being able to recover from any flying atitude by simply pulling up elevator. Here are some videos that trace the evolution of this plane and I will be happy to post the plans for any non commercial builder that would like to make one.

These were the design parameters I thought would be best for this project.

By the way. I have read in more than one place in these forums that it is not a good idea to make a seaplane from EPP. Simply not true, as I have made several with absolutely no problems what so ever.

I will post the plans as soon as I can figure out the best format to display them. The originals are in Corel Draw. The plane is made from 2" x 1.9 lb. epp.

wish I could easily get EPP, best I can do is EPS, but so far ive had good luck with that so long as I make sure to brace it well.

I'd love to build one. Like the looks and handling. What gear do you suggest? Would like to see a full page pdf if possible. Easy to re-size that way.

Nice little plane. I'm interested in plans.
I've been meaning to try pull/pull servo conections for while. Is that fishing line? Guitar string? And what's the best way of getting them set up right?

I will watch the video today and see if I can get the plans up. If not Perhaps someone would be willing to convert them from a DFX. The control wires are 40 pound monofilament. If you watch video two you will see how the mono is woven thru the servo arm to allow adjustment. It's easier than you might think.

Here is perhaps an easier conversion scheme directly from corel draw to PDF...
