Dont mean to jump in on your post but if you can hang in a little bit we are making a kit of the
Dolphin very soon

  I was leafing through an old issue of Model Aviation ( the first iteration of the mag from the early 60's) and Lew did a series of articles on getting into stunt. One model presented was called the "Poor Boy" or something like that and looked a lot like the Dolphin. I was wondering if this is the same airplane, since the Shark45 started out life and "The Humbler."
   Would you happen to know which issue of American Modeler the Dolphin was published in?

Thanks Walter, I may well end up going that way (your kits are well known as being excellent). I have the origional magazine article, stashed from when I was a kid, so I guess that's half the puzzle. When I did a search, I found a lot of conversation on which engines have been used, but nothing on a comparison of the actual construction from the American Modeler plans and the Jetco kit.  I'm still hoping that someone has that information.

Tom,
There are only small differences in the Dolphin kit plans verses the magazine plans.
I have copies of both. Todd Lee sent me a copy of the magazine article to help me with the build. Todd also made a Xerox copy of the decal to help me out also. I built a Dolphin over the winter for our club building contest this past April. I decided to make the model electric powered because I got tired of cleaning 29% castor oil off my Fox 35 models. If you want to build a Dolphin, I would get the kit from Walter Umland. It will save a lot of time and aggravation.

Whoa John, that E-Dolphin looks FANTASTIC!  What is your set-up?  Got a flight report???  I am planning on using a Brodak SuperClown power system in my pending Built-Right kit.

I beleive the Poorboy and the Dolphin are the same, the name change occured at Jetco - frankly I like that change!  I believe there were only negligible differences between the mag plan and the Jetco kit.

After building a couple of Walter's kits, I can only agree: his Dolphin kit will build a LOT better than my Jetco did back in 1966.  His prototype is under construction, hopefully he will be able to release his kit before much longer...!

Dennis,
The E-Dolphin has an Arrowind 2815-09 (KV+920) motor. The ESC is the Castle ICE 50 Lite and FM-9 Timer. The battery is a four cell 1800 MAH. The prop is an APC 11 X 5.5 pusher. I got to use a smaller battery with this setup verse using the Super Clown setup (14.8 Volts verses 11.1 volts). The model with the battery weighs in at 41.3 ounces.

The SuperClown motor is also a 2815, so the motor weight is the same, your 4Sx1800 would be lighter than the 3Sx3300 Super Clown.  HOWEVER, the 4Sx1800 would equate to a 3Sx2400 (closest available size probably 3Sx2600) and that ought to be light enough to enable using the 3S system.

I am always JEALOUS of light builders!
