The classic scale lines and proven capability of the Extra 330SC combine to make it one of the most established and popular aerobatic models. The Hobbyking Extra certainly looks the part and make no mistake, 3D flying is what this superb model is all about!
The quality of this Extra is simply as good as it gets, the airframe has been constructed to keep the flying weight minimal but strong enough to take the punishment of extreme aerobatics. The superb quality covering has been expertly applied and for the final touch, the cowl, canopy and wheel pants are finished in a deep gloss paint. The hardware is excellent & also chosen to keep flying weight to an absolute minimum. The Extra 330SC also features plug in wing & CF wing tube as you would expect for easy transportation.
The Hobbyking Extra 330SC performs every inch as good as it looks, naturaly it makes for a great sport plane but it would be fair to say that hardcore 3D is what the Extra has been designed for. The precision of the airframe, stunning looks, top line quality and amazing feather weight specs make the Extra 330SC a must have plane for all aerobatic and 3D pilots!

This is a fantastic model, flies very precisely and is an equal to my Sebart Angel 50 in terms of flight performance. Very well built with suitable strengthening in the right places, the aluminium reinforcement to the undercarriage mount is a welcome feature.
My setup is a Scorpion 4025 440kV motor and Castle Talon 90 ESC, turning a 16x8 prop giving 1500W and good vertical performance. This setup is fine for sport/aerobatic flying but a bit more power would be needed for all out 3D. Servos are Hitec HS77 on aileron and elevator and HS5485 on rudder. All Up Weight with a 6s 5000mAh battery and Scorpion backup guard is just under 4kg.Finally, the numbers:
- AUW = 3810 g
- Ailerons : Turnigy 620 DMG HS (x2)
- Rudder : Turnigy 620 DMG HS
- Elevator : Corona DS329MG Digital (x2)
- Motor: Turnigy 5065 400kv 18x8
- ESC : HobbyWing 100 A
- Batteries : Zippy Compact 6S - 4500 mAh - 35 C
I have been working on it. It's nearly perfect exept mine has a bad alignment of the horizontal stab...I would say 1-2 degrees. The vertical stab seems to be OK though. Hard to leave this that way in a pattern/3D airplane...It needs a big mod. All in all it is still a very nice airframe !Probably one of the best ARF I've ever had. The airframe is top notch quality. However, theres is no manual in mine (this is not really a problem as this ship is not for beginner).
If really you ant to search for bads I would say:
- It is not really scale (canopy is to forward compared to the real one)
- Cowl fit is not the best I've seen
- Airframe construction is top notch (light, well built)
- Hardware is very good
- Covering is nearly perfect
- Price for that kind of aircaft
BTW you will need 5 servos (2 for elevator).
I'll post my setup and test flight as soon as I can.Fantastic build. Simply stunning quality for the price.

Fabulous build. Balanced perfectly and flew on rails. Most fantastic flight ever. I will probably buy another to have in reserve just in case I mess up.Maidened her today. It is amaizing! Best 3D plane in this size class I've ever flown. I'm thinking of buying another one just to have it by hand in case of crash haha!So, just after she came to me I decideded to make it in electric drive. For the price and quality I love this airframe. Will see how about flight characteristics. Others claim that she flies really good. Aiming not to exceed 4kg with SK3 5055 430kv, Xoar 18x8PJN, Zippy Compact 5800/6s/25c, YEP 80, UBEC 5-7,5A Turnigy, HK47011MG on ailerons and rudder, HS-7775MG on elevators. Will post final setup after maiden and some next 10-15 flights. So far waiting for batteries and servos to arrive. Stay tuned!This plane is great for 3D. After 6 flights I'm very impressed and would definitely buy another. There's no knife edge coupling that I could detect. Elevator, harrier, hover, flat & wingtip spins, pop-tops etc were all very nice.
It needed more upthrust so I added 2 washers to each of the bottom motor mounts.
Here's the gear I'm using:
Motrolfly DM4325 380KV Motor (requires 20mm spacers to reach the front of the cowl),
19x8 APC prop,
YEP 100A 6S ESC,
Castle creations 20A BEC,
Turnigy nanotech 6S 5000mAh batt,
3x BMS-820DMGplusHS servo,
2x BMS-990DMG servo (elevators),
AUW = 4.00kg
This looks the goods all fits great and looks even better using 50/60 380 kv on 6s will report back after maidenThis is such a great plane, put cf landing gear, best plane I've had, 6 cell 20x6 better on an 8 cell same prop, 275 kv 120 Hv esvc, 2000w!! it is the pride of the hangar, got 1.3 balsa Pitt on the way
