So you are proposing a slight INCREASE in Size to offset the extra weight of the
thicker foam ?

I suppose I could fit a scale up on the same size sheet of MPF ( Sticking to 1 Sheet ).
But, it wouldn't be much more than ~10% bigger ...
And I already have submitted larger 33" Jupiter version WAY up above .

We are going from what 3mm to 5mm?

Scaled up gets you to about 36.7", so 33" is certainly close enough.....

Bob, I would love a 33". I've built two of your 3mm kits of the Jupiter (and gave them away to flying buddies). I honestly don't think the weight increase from 3mm to 6mm on the original would be horrible. It is pretty much a floater in 3mm.

Scott in NH;
when my supply of 3mm depron drys up I will either have to
1. DROP the original 3m 22: span
2. do the MPF version that I asked about earlier, and see how it go's.

Bothering with something between 22" span and 33" span seems a little silly IMO.

I hear you , buzzltyr !

The 33" Jupiter is now available,
here ...

Thanks for your patience,

Bob @ Hoosier Cutout service

Jupiter Fleet

Just finished another addition to my fleet of Jupiter Aircraft. I built a Junior last year and just finished a Jupiter Rocket version. Both nice flyers. Both use a Suppo 2204-1400kva motor and 7x6 prop and 2S500mah lipo. Pulls about 52 watts. Weight is 5.6 ozs.

So far, I have built 2 Jupiter Ducks, one a 150% version, a Jupiter Shrimp, Jupiter Junior and Jupiter Rocket. My version of the Sikorsky S-39 was inspired by Thomas' S-39 and I built it before any plans were available.

All fly nicely! Thanks, Thomas!

Joe, it is a great joy to me to see your models. Thank you for building them and posting the pics and videos.
That is why I make the plans - to see people enjoy the models.
