As for the RPM #s on the air wild 27-10 on a DA the airwild prop that was taghed was my prop on another guys engine I also have another airwild 27-10 and it will turn 200 to 300 more on the same motor. so there is variables in props that will also allow rpm's to be higher or lower so what this DA turned on this airwild it might turn the same RPMS with the 27-10 you have so again comparing #s with out using the exact same prop does not tell you anything. Props vary in weight stiffness and this relates to how much they flex which can cause higher or lower RPMs depending on how the prop acts. I am still looking forward to seeing the engines run and seeing RPM numbers for myself inperson. As has been said some people have happy scales as well as happy tachs. Also Keith what is the status of the motors being ready.
