"Then I put on a 12" loop of .078 rubber. I got it to go 1 min 26 sec and it
went up to the ceiling."
"If I remember correctly it ran out of winds about the same time it landed."
At first glance, that would seem to be about all you could get out of this
plane and rubber in this location. However, it is possible you are using a
heavier motor than this ceiling height allows. Also, you may not be winding
the motor as much as you can. Check to see if you are able to get more turns
into the motor. Break a couple short motors in and wind to destruction to get
an idea of maximum turns capacity. If so, the plane may hit the ceiling
with more turns, then Bob's advice is good; use a thinner motor. The thinner
motor will allow more turns with a slower climb and the flight trajectory will
fit under the ceiling. Having the length limited to 12" simplifies motor
selection! You just need to try different cross sections.
Don't try to save rubber by under winding. Rubber is fuel, burn it!
One thing to keep in mind in a contest is that you can make a 12" motor, but
after winding it tight a couple times, it will be longer than 12". The
rules may or may not specify, better read them carefully.
