3DHS New Products and General Plane Info/Help for Fanatics

[Crashes A Lot]

If I had to guess (and this really is just an educated guess), that they will only make them for the balsa bigfoot. I remember hearing in a podcast, or some video from a fly in, that they were only going to make floats if they couldn't find ones already on the market that worked well.

With that being said, having seen the foam bigfoot, I have a good feeling that they might be able to modify it easily enough (or the owner could) to be able to use the floats for the funcub. Especially since the floats for the funcub aren't all that expensive either (but they are super fun! )

Being relatively oblivious as to what determines a plane's engine requirements (other than obviously weight and drag), why is the new 92" Edge going to be 50-60cc, when the 103" Extra (only 11" greater wingspan) requires 100cc? Does 11" really produce that much more drag? I realize the fuse is slightly larger too, but it just seems odd to me.

Scott posted along time ago with a list explaining about that the size difference
Is more than wingspan but instead cubeically

example from Scott:

As Josh mentioned, giant-scale feel isn't about the lightest wing loading. It is about a range of cubic loadings that allow enough energy for tumbling 3D, clean tracking, wind penetration, etc. We've found a cubic loading range that works really well for mid-sized electrics (like the Slick) up through giant-scale.

Cubic loading, unlike straight wing loading, takes into account the fact that as you scale models, their ability to carry weight changes exponentiallly while retaining a similar feel. Wing loading is really only applicable when comparing models of the same size, so it doesn't transfer well when scaling up and down. For instance many giant-scale airplanes have wing loadings of at high at 40 oz./sq/ft. Imagine flying a foamy with that loading - it would be crap, but the 40%'er is awesome at that weight.

For reference purposes, we design our mid-size models (and Andrew has designed his Slick) to be loaded in the 8-9 cubic loading range for best performance. This is the tool I use for cube loading

A couple of examples follow below:

40% model, 2400 squares, 38 lbs, cube loading 8.7

87" SHP, 1450 squares, 16.5 lbs, cube loading 8.3

55" SHP, 640 squares, 80 oz, cube loading 8.5

51" Slick, 530 squares, 60 oz, cube loading 8.5

Kudos to Hugo for referencing Scotts post. Exactly right.

Is this thing on ..check check 123

 

[Baughie]

anyone have some SFG's for the 119 extra 330 that they would be willing to sell i got my 119 used and it did not come with them.

48" Extra EPP and a 57" Extra?

48" Extra EPP and a 57" Extra?

Good guesses - 48" EPP Yak & 71" Slick plus motors & servos.

I only need a 74" Edge to complete my 3DHS 70's collection.
I may pass on the Edge and go for the Bigfoot.
