The current EVO-III gear has a big lip around the ouside and the Tamiya plate drops right in perfectly. I think the Penguin plate is larger on the OD, so you can only use it on the old flat gears or the Xenon or Tc3 Gear.
Our P2705 EVO-III gear adaptor is counterbored to support the gear from the center all the way out to the outer lip, The plate is the entire diameter of the gear. This is why the gear is supported enough to eliminate all stripping caused by gear flex which is the main cause of the EVOIII gear problems.
Thank you,
