Nope. Sadly there is no SAE standard for measuring HP from RC engines as I understand it. xtreme rc is trying to have their method of testing become the standard and I hope it goes that way but it doesn't seem to have yet.
It's almost like the old car stereo days before RMS ratings for wattage. 100 watts RMS (Root Mean Square) was equivalent to 1200 watts peak music power.
From a marketing stand point to uneducated consumers what looks better? 'Nuf said?
