Paul, what size bolts do you recommend for mounting to the firewall.

Is there a difference in bolt sizing between the 4 corner mounts and
landing gear mounts? Do you recommend different size firewall bolts for the oil pan mount design versus the front plate mount design? My pre drilled firewall holes are 3/8" is this good enough for a non p port Renesis

The oil pan mount is problematic due to oil leaks and heat into the rubber mounts.

Usually 5/16th bolts hold the motor mount but you can go all the way up to 3/8th with out adding much weight :)

I am thinking of mounting the hyd strut type  nose gear to the oil pan
like the Questair Ventur. That way all nose gear loads are directly reacted by the mass of the engine. What do you think?
