Developer Scott Stoops introduces the 87" Extra SHP:


The new 87” Extra SHP is the culmination of several years of development towards creating what 3D Hobby Shop considers to be the ultimate 50cc aerobatic RC aircraft available today. Our initial design goal was to create a model that flew precision as well as 3D better than any existing airframe on the market, while still maintaining the high level of prefabrication and quality engineering that 3D Hobby Shop is known for with our smaller models. I couldn’t be happier with the results!
When you first see the model, I guarantee you’ll be amazed at how big and light it is! With gas setups, we’re seeing production weights in the 15.5 pounds (mufflers) to 16.5 pounds (canister setup) range, which is pretty amazing for a model with nearly 1500 sqaures of wing that is 90” long. Basically the same size as many 75cc models, but lighter than the average 50cc model, how’s that for performance! As many of you know, I fly at nearly 6000 feet in the thin Colorado air and I’m seeing excellent punchout from a stock DA/DL 50. The only way to get that is to go light, which the enormous 87” SHP is. Sea level performance in the thick air is even better.

Aerodynamically, the 87” SHP is a radical departure in performance from the typical
50cc model. We optimized not only the areas and moments of the airplane, but also the location of each component to minimize/eliminate coupling making the airplane as pure an aerobatic performer as I’ve ever flown. Its long tail ensures great precision tracking, while the deep bevels and generous control areas allow for outstanding pitch authority during aggressive 3D flight. Taking that one step further, we also incorporated our special thin “Stoops” 3D airfoil section from our smaller models into the 87” SHP which virtually eliminates rock in harrier flight and allows clean pitch transitions through the stall. You won’t find a model this size that 3D’s or locks-in better than the SHP!

In short - if I had to choose a single model to fly for the rest of my life – this is the one.

greet plane

I'm sure it is a good flier but it is one fugly plane.


Albert

Looks more like a G202 / Edge / 1off plylon racer may be F3A

aggggg who knows anymore!!!!

Good thing is its light

I actually think its a pretty sweet looking plane, and it flys amazingly well.
Its so stable for a 50cc plane. It locks into a line very nicely.

I'm one argument with my wife away from pulling the trigger on one of these.
I haven't had a 50cc plane for almost two years.

BUT and its a big BUT .....................is it within the 10% scale line margine and if so compared to WHAT?? Extra . If not then it falls with the F3A planes and thats some realy different stuff high speed compeditive action.

If it is suppose to be a 300 then the canopy is wrong it should be a two place canopy.

Just based on wingspan vs. length, a perfectly scale extra at 87" wingspan would have a length of about 82". So a 90" length is pretty much within the limit of the 10% rule.

Even if it weren't within the 10% rule, I can't really think of any CD that would turn away a competitor with a 50cc airplane. Where I fly, most people in basic have a 40% airplane anyway. We'd let em fly, we're chill like that in the Northeast.

It's supposed to be the new 1-place 300SHP.

I don't think the SFG's are very scale though.

Flip, take a look at the 88" Extreme flight Yak and tell us if it falls within the 10% scale line margine. It only takes a few minutes to figure it out.

I forgot all about the new extra, you're correct. How are you and your dad doing ?


Albert

I'm pretty sure Ben/3DHS makes 3D planes, that are designed to fly amazingly well and be aggressively lite, I really don't think his intensions with this plane or any of the smaller electrics was to compete in top gun, or the scale masters.

If your looking for a plane to FLY and have fun with, this is one to eyeball.

Too funny. I'm proud of the airplane - regardless of whether the lot of you think it looks good If only we could convince the likes of Extra, Sukhoi, and Cap to add SFGs to their airplanes.

Heck, if you think the Carden Yak looks like a Yak, you don't know what a Yak looks like. I'm all for "morphing" at least a little to make them fly better. If its good enough for Quique, then its good enough for me.

Scott

That pic in the first post is squashed, making the plane look funky and short. It's actually 3" longer than an EF Extra 300.

The canopy does seem to be a little too tall, but I think it's just the paint lines on the clear part. If you paint up another 1 1/2" or so and cover more of the clear part, it looks a lot closer to the scale 300 SHP outline.
