RE: It's here and Looks GOOD new Hangar 9 Taylorcraft
Zippi, I understand the stand offs and the distance from the firewall to the cowl end and air gap for spinner etc. The manual in the ZENOAH ENGINE BOX clearly states that the firewall should be 8mm thick to mount the zenoah 26cc. They are not referring to the standoff depth or anything like that, but how beefy the plywood is on the firewall. Hope that clears up my question.
