I don't care about smoke on low altitude flights, but I want lots of smoke to be able to follow high altitude flights. The new delay that Estes and Quest are using just does not produce the 60's volume of smoke. Fire a new engine on a test stand and the yard clears of smoke in seconds. Fire an old engine and the difference is significant.

The B14-0 and B14-7 have got to be some of the most requested engines at Estes from the old-timers.
