It's not too surprising. A Stryfe with stock motors and flywheels running on 4 IMR cells with a 16AWG rewire (although I believe it's the standard switch) can achieve 113fps average with a min of 105fps, a max of 120fps and a std. dev. of 3.7fps. 3 IMRs with stock motors and flys can achieve a slightly more modest 109fps average. You can even get similar results with unprotected LiCo cells such as Trustfires/Ultrafires in otherwise stock blasters (which some people cite as evidence that we're "wasting our money" with upgrade motors/batteries).

This setup should have better spin up/recovery performance than those examples with stock motors but it'd be interesting to compare it to other lower KV/higher KT 130/180 builds.

Can I get the complete data set? I'd like to see the distribution and do some more in-depth analysis? Smile
