3D Hobby Shop is pleased to announce there all new 47" Extra 300 SHP (Super High Performance) 3D airplane. This Extra is a 3D Hobby Shop original design that was developed by Scott Stoops (sukhoi26mx) in cooperation with 3D Hobby Shop and their partner factory in China. The sole purpose of the Extra 300 SHP is rock solid 3D flight to the MAX!!

47" Extra 300 SHP Specs:

Wingspan: 47.25"
Wing Area: 464 sq. in.
Length: 44"
AUW: 37-41 oz.
Wing loading: 11.4oz./sq.ft.-12.7oz./sq.ft.

Recommended Equipment:

Motor: Torque 2818T/900
ESC: Torque Airboss 45A Elite
Prop: APC 13 x 6.5E
Battery: TPX 3s 2070 25C
Servos: (4) HS-65HB

The Extra 300 SHP will come with all the same high quality hardware that the current 3DHS Yak-54 and 3DHS Katana models utilize. However in addition to that the Extra 300 SHP will also come with convienent changes.

- Hinges come pre-installed in all the surfaces.
- Hinge slot in the rear of the fuse now comes pre-cut.
- All Extra 300 SHP's will come with 52mm heavy duty wheels (very solid).
- Scale looking Extra 300 CF landing gear (no straight CF legs on this plane).
- Pull strings in each wing half for aileron wiring.
- Firewall hole is now a perfect match for the Torque 2818T/900 motor.
- 3mm motor mounting harware included.

All 3D Hobby Shop airplanes are made of light weight laser-cut balsa and light plywood. The Extra will come with a pre-cut fiberglass cowl and wheel pants, uniquely effective canopy hatch attachment, and a two piece removeable wing which rests on a carbon fiber wing tube.

3D Hobby Shop will be taking pre-orders on there new Extra 300 SHP within 24hrs. These planes will be available in March and will be offered at a price of $149.99 for the Extra 300 SHP ARF. There will also be a power-combo being offered which will include the airplane, Torque 2818T/900 and the Airboss Elite 45A speed controller for $269.99.

The Extra 300 SHP is designed for all out 3D flight. The Extra 300 was developed around a wing that has a thinner airfoil with very accurate, sharp LE that makes for a great stall breakaway and very precise flying airplane. To better understand this concept I would like to suggest you take a look at this thread (see below link). The posts in this thread clearly illustrate the benefits to 3D flight that a thinner airfoil wing can have on a 3D airplane. What this all comes down to is a 3D plane that will be rock solid in high alpha flight modes, can be flown at slower speed with out the fear of a tip stall and a plane that someone can build confidence in very quickly.

One of the things I notice with new planes when they get announced is there is never any video to see how the plane actually flys. Not to be the case however with the new 3D Hobby Shop Extra 300 SHP. Here is a little "teaser" video for you.

Paul,

I agree that there are alot of great models to chose out there these days. I would give Ben a call at 3D Hobby Shop, he has flown many of those listed and would be happy to point you in the right direction.

I was able to dedicate some time to working on the Extra SHP today after working on some honey-do-list items. The Extra build is very straight forward and has offered no looks on my face. The parts fit has been excellent with all pieces and surfaces have fallen right into place. Many of the building steps are very routine procedures as with any arf model. I did however confirm that all the CA hinges are PRE-GLUED to there control surfaces. What this essential means is the ailerons and ca hinges were ready to glue to the wings, the rudder and ca hinges to the vertical stab and elevator halves and ca hinges to the horizontal stab. This greatly speeds up this step of the building process.

As Scott method earlier in this thread the control surfaces on the Extra, expecially the rudder (HUGE) and elevator (EQUALLY AS HUGE) are some of the largest I have ever seen on a model this size. The horizontal stab on the Extra sits slightly lower then the full-scale Extra SHP. I believe Ben or Scott can touch base on the reasoning behind this. You might want to watch however using full down elevator while taxing as it looks like the elevator could drag some. The carbon fiber landing gear really sets the Extra SHP apart from any plane in its class. It gives the Extra a very scale look and appearance on the ground. The landing gear plate looks to be very strong and capable of withstanding less then perfect landings.

Next I moved on to mounting the motor and esc. The Torque 2818/900's radial mount now matches the hole in the motor mount perfectly. Simply align the two together and mark your holes and drill them out. The mounting hardware is supplied and works like a charm providing a very secure mount of the motor. The Airboss Elite 45 will be offered with the package combo's that Ben will be selling soon through 3DHS. One nice feature about the Elite 45 is that it can run up to 5s lipos on the internal bec (sweet). Not only will this save you money in the long run but it will also save on weight for those who normally run their planes on seperate bec units.

The only things left to complete are the mounting of the servos (HS-65Hb's all around) as well as control horns and pushrods and attaching the cowl and connecting up the rx and wrapping up on a few little details. The wings attach to the fuse with just two plastic thumb screws and have one small wooden dowl per wing half that acts as the anti-torque pin. This is slightly different then previous 3DHS planes which used two plastic thumb screws per wing half. The wings mate with the fuselage perfectly with no gap to worry about. There is also plenty prop clearence as well with the 13 x 6.5 prop. Someone could easily use a 14" prop on this plane should they need to with the stock gear.

I decided to do a mock up of the Extra SHP as this build has been going so quickly that I am hoping to have it done by mid-week at the lastest (probably earlier). The Extra really is set off with the new Hyperion 40mm spinner. It gives the Extra that additional scale touch and is very light weight. The Extra looks like it is ready for flight just sitting on the work bench. This is indeed a very impressive looking model and I can not weight to get it up flying.

The last few things that I needed to finish on the Extra are done and the plane is ready for maiden. As far as the wrap up items they went very quickly and without any issues. The HS-65HB's fit perfectly into all the servo bays. The included steel pushrods and accompany hardware works great and lends itself to a very quick, simple and highly efficient setup. The aileron servo bays are recessed some to allow the 65's a lower profile look. There is plenty of surface deflection with the aileron's just by using one of the included 65 servo arms (used the same arms on the rudder and elevator). The elevator setup and rudder setup were equally as easy and went together without a hitch.

At one point during the rudder pushrod assembly there was an initial concern with regards to the pushrod clearance when the elevator is fully deflected (over 40 degrees). But once the rudder horn was installed and everything was connected there was plenty of clearance between pushrod and elevator. The super nice fiberglass cowl really sets off the Extra. It fits perfect and is held in by four screws, pretty standard setup. One thing I wanted to do was see how much less the Hyperion spinner weighed compared to my normal Dubro 2" spinners I usually use on planes of this size. The Hyperion spinner weighed .5ozs lighter than the Dubro counterpart. to be continued......

Well I am extremely pleased with how the Extra 300 SHP turned out. It looks absolutely stunning and I am extremely excited about getting it up for its maiden. The Extra comes in at 32.5oz. minus the battery pack. With my TPX 3s 2070mah pack the Extra comes in at 38.5oz. RTF. For a plane of this size with a wing area of over 460sq.in. (464sq.in. to be exact) that brings the wing loading to only 12 oz./sq.ft.. Yeah.... the Extra should fly nicely and 3D like... well like crazy. I have the cg set at 3.5" measured at the fuse from the leading edge which puts the cg right in front of the wing tube. After a few flights I will gradually move the cg back to find the sweet spot for all out 3D flight.

Over all I think when it comes to the build, 3D Hobby Shop in association with Scott Stoops have really made it simple to take a plane from box to flight ready in a very short time. The amount of engineering and design that went into this plane is phenominal and I tip my cap to Ben and Scott for setting out and designing a plane with such innovative ideas that will help help all of us improve our flying and 3D skills. Enjoy the picture extravaganza!! If you have any specific question regarding the build that I may not have addressed please feel free to let me know.

Beautiful plane!!!

SS2P

I will be getting ultimate combo on 3dhobbyshop as soon as it is available. It definitely looks like a nice plane. I was wondering if AB 45 esc can handle 4 micro servos like HS-65.

Wish me luck

Yeap the Airboss 45 will have no problems with 4 HS-65's.

Maiden Success!! It's time for a another flight report:

--------------------------------------------------------------------------------

Well, after waiting for over a week for the weather to improve since completing the Extra SHP build today the weather actually cooperated enough for a maiden plus 3 more additional flights. The maiden was a complete SUCCESS and really left me in awe on how great this plane flies. The weather was sunny (yes sunny in OH) and in the middle 40's with a wind blowing about 7-8 mph. The plane was unpacked from the SUV and after doing a range check (and gut check) I applied a gradual throttle and within less then 15ft the Extra was airborne. In the winds I had today the Extra will take off after a very short roll-out if you are aggressive on the throttle. My Extra only required two clicks of right aileron and a click of of up elevator. From there it was hands off!! The Extra tracks very precisely on low rates and with my cg set at 3.5" at the leading edge measured at the root the Extra really cuts through the sky. After trimming up the Extra I wanted to see how the stall characterics were. As David noted in his report the Extra has a very benign stall and simply mushes along with the nose falling slightly until the Extra picks up speed again. I found no signs of the Extra wanting to drop a wing. On low rates the Extra offers no suprises and I found no pitch divergents with this cg setting. Landing the Extra really is a none event. I simply maintained a low throttle setting untill a few inches from my intended touch down point and just let the Extra settle in. The carbon landing gear works great and really looks awesome on the low level passes.

So how does the Extra handle on high rates (3D) you say?? All I can say is the Extra is a real confidence building type of platform. It is not normal for me (maybe for Ben or Scott or others) to harrier 10ft. off the deck after only flying a plane for three times. But yes this is exactly what I was doing with the Extra today. WOW, I was extremely pleased in that I did not have any wing rock in inverted or upright harrier flight. On my first couple of harrier passes I was a little aggressive on the rudder and did have some rock but after relaxing my left thumb some (it was still kind of cold out) and coordinating it with the ailerons I was able to remove any rock I was inducing. What about KE flight? On my first high rate KE pass I actually put the Extra into a climbing KE pass that I kept going with in to a 3/4 KE loop ( I chickened out at the bottom). I found the Extra had NO coupling in KE flight but the wind at times made this hard to be sure of. As I get more flights on the Extra I will confirm if this is correct or not. One of my favorite maneuvers is the KE spin. The Extra does a beautiful KE spin with low throttle and can still spin around center (very scale looking). Blenders on the Extra really flatten out and with careful throttle management you are rewarded with a terrific looking inverted flat spin. Over all I am extremely pleased with the Extra's flight performance and am looking forward to getting more flights on it this weekend. I tip my cap to Ben and Scott for producing such a tremendous looking and AWESOME flight airplane. It really has boosted my confidence in flying the Extra in just a few flights.

I can not take all the credit for the maiden today. I was thinking to myself that the Extra was missing something. I just couldn't put my finger on it, and then it hit me. The Extra needed to have a pilot, with that great looking cockpit it had to have someone behind the yoke to fly it. Sooo......... let's see can anyone tell me who might be piloting my Extra 300 SHP??

I have included some picture from today's outing. BUT WAIT!!! You said there was going to be video!! Yeap, I got some and I just need to edit it some, so it will be coming soon...
