do you have an 85?

Yes. I started this thread about a stand off for it........... Ended up making my own and found that there is needed clearance where I pointed out. Actually I did a poor job of describing where the clearance was needed so here is a pic.

Have you mounted and flown an 85 on this mount as you have it in the pic? On my 85 it would be impossible without hacking up that mount and at that point it would be too thin IMO.

On my DA85 this Fritz mount would not work, see the mount I made with side cutouts quite some time ago.
With a ball link on the outside of the arm there is no clearance with the Fritz mount.
Manufactures should test stuff before it's sold and the public gets it. Even if a simple test/check.
How do you adjust the needles with this Fritz mount? Am I missing something?
Sorry, it's on the Fritz.
Could not resist.
Some minor changes and it could be a nice setup.

Here some pictures and a drawing of the Fritz's Motor Box

The first 6 layers have a cutout for the throttle linkage.

This is a regular ball link - low and full throttle with and without the motor box - please look closely and you see the cutout. It is maybe confusing the other end of the box has a different shape - but this was the nearest solution to keep the strength to the maximum.

Sorry for the mix up.

Even Fritz took a second look...[8D]

The same way as other boxes or firewalls...

Right on. I see it now. Surely you can see why we were confused. The last pic shows the pieces we didn't see before. Nice mount BTW. It's prices is the fairest I have seen yet. Good work.

I have to eat crow.
The picture with the cat does not show the step in, but your cad model does.
The arm included with my DA85 will not let the arm come out using the side to hole placement you have.
Must be changes all the time.
The cad model does not have a opening to adjust the needles, do you just cut the stack where you want?
Not a problem to do so.

None the less I am glad someone came out with a solution.
I am one of the old farts that makes a lot of stuff and spends the saved money on other items.
I hope you do well on sales!

Hi. I'm still very new to gas engines and I want to learn more.

I ask this question of G-Pete sincerely and with no intent of being abrasive. How do you adjust the needles with your mount? It looks as though you would have to remove the engine for access! Or do you just drill a hole(s) in your mount?

tkilwien's mount offers a well designed access without having to remove the engine or drill holes.

Please forgive me if I have missed the obvious.

You would need to drill holes in the mount. The nice thing about this mount is you can mark where the holes go before you assemble the box. I am currently working on detailed assembly instructions that will be available. The goal was to make a easy to assemble motor box for the masses that may not have the proper tools, knowledge or time to make one. These motor boxes are made in the USA and are a DA approved design. Our goal is to prove that quality doesn’t have to be expensive.
