Thanks Matt, I want to convert an old Oxai Astral XX thats retiring from active F3A duty to the 33.
It has engine bearers to take the YS super mount so I'm undecided on whether to cut them out reinforce the firewall and mount off that OR leave the bearers in place and make an alum angle piece that picks up on the 33 standoff points and attaches to the bearers via a rubber interconnecting piece, what do you think?
Cheers
Greg
Greg, i don't know what the bearers look like. Would you take a photo for me? Are the bearers themselves soft mounted? Are they screwed in or do they need to be ground off?
If the bearers have a mounting surface that is on a common plane (top and bottom mounting holes on a common plane), the second option might work. Not sure about the "interconnecting rubber piece" tho.
You might be better off in the long run tocut firewall and bearers out and start anew. It would be lighter and probably stronger set-up.I use cross grained balsa/carbon laminate for firewalls. A soft mount designed for stand offs simplifies the installation. Stand off length I use is 1".
Does the Astral have a pipe tunnel long enough for the ES Composites 30G pipe? Which YS did you power it with? If it was the 160DZ or smaller, the Astral will come alive on the 33
