Latest foam .50 Delta
This is a practice plane I just finished. I like to have a warm-up plane to fly before flying anything really hot.
WS = 34"
Weight = 3lbs - With steerable dolly 6 lbs!
Engine = Jettfire .50.
1st flight this weekend.

Hey,
Looks really nice, if it flies like it looks you should let us speed freaks in on the construction details.
Can you give some more info/ pics on the dolly it looks as good as the plane

Viper Delta Construction Photos
Sorry I didn't get a chance to fly the Viper Delta this past weekend. I developed air bubbles in the fuel line and with a beautiful day I decided to fly instead of work on a plane. Maybe next weekend.
Construction Photos!
Hope this helps for those who are interested. The foam is from the local lumber yard and hot wired. The engine was changed from a Sport Jett .50 to a Jett fire .50 during construction.
The main thing I like about foam construction is that the foam is a solid where a built up unsheeted airframe will depress and draw the covering material in all different directions in high speed flight. Plus a small hole in the covering from a sharp object on landing will not cause the covering to explode off the airframe on the next flight if it is missed. Also 6 bucks worth of foam will build 4 or 5 planes.
Once on a OS .91 VR-DF, I had the covering on a foam wing peel all the way back from the leading edge to the trailing edge during a high speed run, but with the foam underneath, you still had an airfoil. The plane just yawed to the direction of the trailing shredded, flapping covering. Plane landed safely to be repaired and is still flying.

Servos installed in bays, tank 8oz flat 1.5" tall installed, note GPS bay to the right as you see photo in this illustration. Large enough to hold a Garmin Etrax inside. All bays are lined for strength.

Viper Delta Construction
Takeoff dolly. Construction is very basic and unit weighs about 3 lbs. Large 5" wheels for use where you lack a hard surface. I have used this on turf with no problems even though I primarily fly off concrete. It is very stable, and frankly I can't even remember the last time I had a bad takeoff. That is a good thing!
Now that I use a dolly for take off, I would even consider going back to the old days of just have tossing a plane. This is especially true when you design your own and have to work the bugs out yourself.

Side view of the Dolly. Note the blue foam which conforms to the shape of the bottom of the airfoil. The slot is to accept the removable landing skid on the Viper. If you want as low a drag as possible for a run you can just belly in on the Ultracoat. Otherwise the balsa landing skid take the abuse.
I'm still trying to find a way to land the plane back on the dolly after a flight. Maybe I'm just not that good of a pilot!

Finally the last shot!
The Dolly after a bad wreck.
Here you can see the steerable aspects of the unit. Note a totally separate battery pack, receiver on the same channel for rudder. It's just rubberband mounting to the bottom of the dolly. What could be simpler?

One really cool plane. I've been flying my DD, some say it's a one trick pony, but what a trick! This looks like it'll make a DD look like a slug.

Try an Outlaw, prophang to 140mph to flat spin to blender type thing, to inverted climbing spin. thats tricks
