Motor Mount Length for Stretched Pacer with O-320
Does anyone have any suggestions for a motor mount length for a Bushmaster with a O-320? I will be running supercub tail feathers which should makes things better. However, I would prefer not to have an aft loaded situation. Cheers.

Re: Motor Mount Length for Stretched Pacer with O-320
My stretched Pacer has the normal Pācer engine mount. It is configured well and takes little trim between take off and landing. I often carry heavy loads in back with no problem. No change in the engine mount is called in the STC. Doing so would not be approved and unnecessary in my opinion. I have Super Cub tail feathers which allow me to flair and land tail first without using power. I do not believe that would be the case if I had extended engine mount. The extended wing increases the downward pitching moment which is why the fuselage is lengthened. Forward placement of the engine is not needed. It takes power to do a stall as it is in my plane. My stretch is 22.5 inches and I have the 0-320.
How's the project coming?

Also, my empty weight CG only moved 3 inches aft on my Super Pacer project. Which I believe improves the flair and landing of the Pacer.

Does anyone have drawings for a mount? It's hard to find a used mount. I hear some rumblings about zero thrust straight mounts. I can certainly build a mount if I can find a drawing. Cheers.

Regular TriPacer mount works. Just dont bolt on the nose wheel structure.

I'm not sure if going to zero thrust line makes much difference on our zero incidence planes. I did space my engine mounts up and to the left using large washers between the mount and the firewall. I saw no changes.
