Rotax oil tank mount.

[Murray Parr]

Has anyone mounted the Rotax oil tank to the firewall?

Any pictures or plans to make a bracket and how it is mounted would be appreciated.

Looking for a light weight mounting bracket and wondering what the best way is to strengthen the firewall where it is fastened to?

Just speculating Murray,

Bracket going to be interesting, as will have to accomodate Sonex very sloped firewall.

Strengthen firewall with either an aluminium plate (with lightening holes) OR a couple of aluminium angles, from aged memory, comes in 1.2- 3 mm gauge, equal or unequal sides, from about 10-50 mm. Can be had in short lengths from Bunnings Aerospace (depending on size you want, I might have a bit to spare)

Slope is 60 degrees, I will likely put the tank at less angle. I might copy this one from Skytek https://store.skytekaircraft.ca/store/p ... Kit.html#/

I am completely revamping my cooling and exhaust systems, and current position of oil tank is now in the way, my only space available right now is lower starboard firewall. Interested to see how others have mounted theirs.

Be careful Murray - Rotax have specifications for the oil tank height, relative to the pump.

"I might copy this one from Skytek....."

Looks like you could get much of the aluminium extruded profile from Bunnings OR almost any specialised aluminium supplier (I used to use Ullrich - now closed)

"Interested to see how others have mounted theirs."

Mine is mounted on the starboard engine frame, fairly close to the firewall. Give me a date/time & I will fly in to Goulburn.

I had my tank mounted on the starboard engine frame too, just needs to be closer to the firewall, I could probably change the current bracketing to still use the engine mount frame but think I could save some weight by mounting it to the firewall.

I will give you a heads up next time I go to YGLB, would be good to see the changes you've made since I last saw your Sonex
