I wanted a new plane for our club’s Labor Day fly-in, so I decided to slap this together in a couple of evenings.  Nothing fancy, just a quick build with a quick cover using some left over covering from my F4F build. I wanted to get some video of this flying, but I forgot to put the memory card in my Mobius camera.  I’m not much of a flyer, so I had the club hotshot put a flight on it.  He asked what I wanted him to do, so I said, “Do whatever you think it’s capable of.”  So he did pretty much everything in the Beginner’s pattern.  The plane flies wings level both upright and inverted with a nickel for tip weight.  Plenty of line tension in the overheads.  I didn’t have to add any nose or tail weight with the 8cc tanked Bee engine.  Flew great right off the board on 30 foot lines.  Doug over at Willie Nillies done good with this kit.  As you can see, I saved time by using a Brodak engine mount.  I like them for my 1/2A planes.

After flying the BRM, the club hotshot showed me his old Flip that had about a thousand flights on it.  He recommended I build one, so I slapped this together in a couple of evenings also.  It’s a Dick Sarpolus design.  A TD .051 on bladder will power this.  I’ll try 35’ lines, and have a set of 40’ on standby if the TD tries to screw me into the ground.

C'mon Mark, there's not a bit of slap on those girls. Beauties
both. Stunning! The Brodak reedy mount is a gem.

Brodak offers two versions of this mount. I have the numbers somewhere but one is a beige colored plastic and is fairly hard. The other is white a bit opaque but a lot softer. Both work well, I prefer the softer as it takes a shot a little better. Whenever I use them with a product backplate, the gear wire is bent in a inverted V. The problem is that the wire still moves behind the backplate. I drill another hole directly above the point of the V and use a additional screw with a washer that pinches the wire. It's just nice to have a mount that utilizes both engine types. Whenever I use them. I place a 1/4" piece of beam epoxied into the fuse. It prevents over tightening of the mount. Dick's designs are terrific. Blackhawk Models used a few of them. He's a interesting person to talk with.

Took the Flip out today and put three flights on it before it got too windy.  It was just windy enough.  The plane literally jumps out of my hand on launch.   Yes, I know.  The word “literally” is literally overused, but weighing only 6.45 ounces and running a TD.051 on bladder, swinging an APC 6x3, this literally jumps out of my hand.  It’s just a tad tail heavy, so I’ll either try a heavy Cox prop nut, or just put a nickel on the nose.  Probably go the nickel route since I don’t like the idea of loading up the crankshaft with needless weight.

Here’s a brief video of the Flip flying.  I keep forgetting to turn on the camera before I start the plane, so this picks up a little after half way through the flight.  You can see how easily it goes through the maneuvers.  Sorry about the camera angle, this is the first time I've tried to video someone else flying with my hatcam.

Sorry to take so long to reply, Eric. Yup, I got to fly it, too. Just not as good as Jim. The plane was built from scratch using plans. I don't remember where I downloaded the plans. Probably Stunthanger.

I love them both Mark, but it's the blue and yellow Flip that draws me in.

It's all screwed up said in the most likable way. The wing is on backwards and the profile of the rudder/vertical stab is weird yet attractive. And that rudder........huge.
The forward leaning cockpit adds aggressiveness and is positioned perfectly. I love the whole thing.

I only wish it were mine.

I can't remember where I got my  plans from.  I've tried searching the usual sources and can't find them.  A Dogpile search came up with this:

If you're not registered, it's easy and free.  Lots of plans to download

Very nice looking planes. As well, the Flip goes good! I have had the plans for a long time, and have always wanted to build it, but..... Hangar space is at a premium now here, even with the little ones. I have even given a bunch away and have more to give away as well before starting my next one.

Roddie, I normally use 5 inch props for my sport stuff, but for the TD I used an APC 6x3. Worked great, although I didn't tach the prop speed.
