Here's some pics of the main gear that I made for this model. Nose is next. Has any one done this yet? I made a couple extra sets of gear.

These gears are "Dumas" design.Do you use cnc machines ?
They are well made...congratulations !!!

I bought a set from Robbie,, they came today and look fantastic.

I have more questions now though.
1-could you email me the reduced size CAD file so I can print out a template for the attach points or just give me the reduction %
2- which robostrut # do you have in the picture?
3-How did you plan on pinning the strut brackets
4-?? I'm sure I'll have more

BTW,, Thanks

I thought that I would use a robart 660 cut down. The shock sissors will have to be modified to shorten the shock absorber from 1" to about .5". I thought that I'd put a set screw in the brackets surrounding the strut along with J.B. Weld. I reduced everything by 10% and then reduced that 8%. I can send you measurements from point to point via email.

So you want to shorten the "droop" to .5",, I'll have to think about how to do that,,

I see in your mock up it seams you changes the strut angle from scale, I assume so you wouldn't have to bend the axle or the lower strut,, that seams like a reasonable compromise,, I was thinking I could always cut and re-weld that strut angle,, might not be worth the trouble though

should be a fun project

Curious if you ever did more work with this set up??
The set I bought from you has just sat in the bubble wrap while I worked on other projects, slowly,, I kinda lost interest and it's all up for sale now,,
I really need to stop doing that. maybe if you've made progress I can get inspired to tackle this project.

How's the 415 build going?

I'm really thinking about one of these. Seems like a lot of airplane for the money, and I'm hooked on seaplanes anyway. Would make a great electric converson with a pair of Turnigy G46s.

I haven't touched it since last fall. My business is winter oriented and have been too busy. I have the main gear installed on bulkheads in the plane. The air cylinders are installed and everything can be moved by hand. I'll post some pictures.

Thanks, mon, looking forward to em.

After looking at another post and finding out that electric RTF weight is between 12-13 pounds, I think I'm gonna go for some bigger motors. Gotta recalculate, anyway.

What size are the spinners? I'm going to use tru turn (tractor and pusher).

I ran some numbers on the Turnigy G60-500, using Markus' ecalc, and they look real good with 13x6.5 APC E props.(63mph and 17# total thrust on 41A apiece) That arrangement would allow going up or down in power and amperage by merely changing props, too.
