Rocket Pig!

Now that pigs have flown, they have no excuses for not having releasing the plans.

A suggestion so only one person is needed to launch and fly the pig is install a extra servo in the pig that the servo arm acts as the igniter when the switch is flipped on the transmitter.
How it works is use one cell of the three cell battery(used the balance input connector) so you have a + and - wire. One lead(used telephone wire) goes to rocket, the other lead from rocket to the end of one arm of the servo that has a small metal tab. When switch is flicked, the servo arm moves and makes the connection closed from the servo to the other one cell connector. Be sure you stress that the rocket being used is labeled zero so explosive does not fire(empty) for parachute.
I have a video if you like. Like Dave, I kept on backing up(nervous) and from calculations(weight of plane plus size rocket) and Estes chart, it probably went 400ft high. Had elevons on plane and even got to use control on way up. Project was suppose to release from transport, fly down, pull nose up and fire rocket, ascend and land under control. Result, a larger wing area was needed. Probably the fastest plane I ever flew.

You were using a bigger than "D" motor? Their rocket plane only looks to be going up about 150-200ft. Typical for heavy stuff. Pig looks like it might make 100 if the wings stay attached or don't fold but they really need a launch rod or ramp system. The estes chart was very optimisticly inaccurate based on triangulation we did. Dont even think @L Edge could pull off a ignite and climb sequence because you never know when it's gonna actually light off unless you're using a dedicated really high amp ignition
How about a plastic piggy bank fuselage?

Yeh, I used 2 wire rods at an angle of about 60 degrees for mine. The igniter worked, for it was about 4+ volts and telephone wire. Probably faster than my Formula 1 plane. Did 2 dry runs of just rockets since only one plane..
The minute I saw the pig and its launch angle, knew that was a winner. Especially when they used throttles on launch, knew it would work.

Yes. The original! I've been asking FT for piggy sbk/plans from the beginning. Just around the corner, now.Hi Everyone,
A little old school way of making Pigs fly. Enjoy
