wasp....... guys only used 75% for our speed dash last year at the championship race. It was won by Richard with a 203mph run on my 13x18 prop.
guys hate all you want lol
propworn again your understanding is flawed YS has CDI engines from the 70 on up. They are fixed timing but can be programmed with an aftermarket ignition. This CDI with its fixed timing does allow a better needle over glow ignition that changes timing as you lean on the needle.
Most guys run high nitro so not sure how many times I have to say that lol. Also most guys try to prop the 115WS around the 10,000 to 11,000 on the ground. I like to see 11,500 to 12,000 on the course.
OP sorry this went in many different directions. If you have any other questions feel free to hit me up with a email.
