H-9 Suhkoi & DA 85
I have aquired a new DA-85 engine and am going to install it on a H-9 33% Suhkoi does anyone know the stand off lengths from the firewall to the engine required in "mm" or "inches" that are needed to get the correct clearance for the cowling for this combination?

RE: H-9 Suhkoi & DA 85
The new SU-26mm is designed for the DA-85 to bolt directly onto the firewall. The distance from spinner to fwall (or length of DA-85) is 152.4mm. The 33% SU-31 distance from fwall to spinner bp is 187.9mm. So you'd need 35.5mm standoffs behind the DA-85 to mount it in the old SU-31.
