Officially licensed scale replica of Aviat Aircraft Pitts S-2B aerobatic airplane

Hangar 9 has a winner on their hands here and I know this because this is the first airplane that nearly all of the RCGroups reviewers sent me messages requesting it as soon as it was announced. That's powerful and shows an extreme interest in this Pitts. It certainly seems to hit the sweet spot in terms of size, price, performance and looks.

For the sport, scale, and aerobatic pilot, the new officially-licensed Hangar 9® giant-scale Pitts 50-60cc delivers on a classic-scale aerobatic platform with true scale proportions, ease of assembly and impressive flight performance. Featuring scale details typically not found on other ARF aircraft, the incredible recreation has outstanding flying characteristics that Hangar 9 is known for around the world. Constructed with lightweight balsa and plywood for a rigid and strong airframe, it features multiple quick release hatches allowing for easy access to fuel equipment and electronics. The biplane exhibits an iconic scale scheme by airshow pilot Rich Goodwin, quad aileron servos for precise control and aerobatic agility, and so much more. It will perform extreme aerobatics just like its full-scale inspiration using your choice of gas or brushless electric power options. It comes out of the box with a level of scale fidelity that truly sets it apart from the rest. No matter how you fly, the Hangar 9® giant-scale Pitts S-2B ARF delivers incredible thrills at the flying field. The Hangar 9 Pitts S-2B is available for pre-order right now at $799 with shipments expected to begin later this month.

Can we get an accurate flying weight? 25,000 grams = 55 pounds. Seriously dubious....

It appears the new website change has some issues. Should be 18 to 22 lbs, with the lighter weights being gas with a small battery, and the heavier with electric and 12s/7000's. Using 5000mah packs drops roughly a pound over the 7000's. Then there's the difference in using BEC or a seperate rx pack. So you see the weight range may sound pretty large, but encompasses all the variable. In the product video, the gas one is a DLE 60 twin, using two 4000mah 2s packs, one for ignition and one for rx(spektrum 9350). It's well under 19 lbs dry. The electric in the video is using a powersafe rx with two 2s/4000mah packs and with the larger 7000 packs it's at the upper end of the range,.. but still flies light.

Thanks Gary. What kind of flight times do you get with the 7000's? What prop are you running on the electric?

6~8 minutes, but prefer 5000's with the lower weight. Use less throttle so flight times really don't change much. Currently have a 20X10 on that one but it's more power than really needed.

Thanks! How many RPM does it turn that 20x10?

Tached today. 20X10 Xoar just over 9000, settling to 8900 after a few seconds and staying there. It's not optimally propped, needs much lower pitch and then could use more dia. Probably 22X6 or 22X8 would be better but we don't have those in our Product testing inventory of about a gazillion props.

Thanks, Gary. Was wondering how it compared to the Power 160 that turns a 20x10 about 7200 on 10S. I have a Power 160, but doesn't look like that would be a good choice for the Pitts. Appreciate your followup. -- Randy

I know it doesn't sound like that much but the difference in 7200 to 9000 is close to double the power. Everything else remaining the same, Wattage goes up as the square of voltage difference and the cube of the rpm difference. So, 8900 is roughly 1.23 times 7200 (talking rpm differences). 1.23X1.23X1.23 is 1.86, so the wattage (horsepower) to spin the same prop (20X10) at 8900 versus 7200 goes up to 1.87 times the initial wattage. To make a short story long,.. this setup is making near double the horsepower, which makes sense as the motor is near double the size. Also,.. 20X10 on the power 160 on 10S is way too much prop unless you have an abundance of cooling, use throttle very carefully, and fly it only in cooler temps. If it is working for you, in your climate, with your throttle usage,.. that's pretty impressive! but I would not recommend that much prop with that motor/cellcount.

The Rimfire 50cc at 230 rpm/V seems like a very high Kv for 12S.

Would not a motor around 180 rpm/V, eg the Power 360, which would readily accommodate 22x10, 22x12 or 23x10, be a better choice in achieving higher specific thrust and pitch speed than dropping to 6" pitch to use a 22" prop with the Rimfire 50cc?

Yes, the power 360 would be a great choice. It's more expensive but would allow a larger prop. right thrust that's built in to the model is appropriate for 20~22" props so its appropriate for the rimfire and the 50~60cc gas engine. May need to adjust with the larger props on the power 360.

Looks like E-flite recommends the P160 with a 20x10 on 10S. From the Power 160 Manual:

Hangar 9 27% Extra 260 Scale ARF (converted to electric)
Option 1:
Motor: Power 160
ESC: Castle Creations Phoenix HV-110 (CSEPHX110HV)
Prop: APC 20x10E (APC20010E)
Battery: Thunder Power PRO LITE 5300mAh 10S4P (2 – THP53005S4PPL packs run in series)
Flying Weight w/Battery: 15.3 lbs
Amps Volts Watts Input Watts/Pound RPM
76 36 2740 179 7250
Expect excellent vertical power for pulling out of hover with authority and plenty of power for knife edge loops. Good speed for maneuvers at ¾ throttle, and is a setup well suited for IMAC
flying. Average duration is approximately 7-12 minutes depending on throttle management.

Interesting. Knowing how things are tested, I'm sure it's just fine there and I was wrong.

Haven't completed my setup yet, but guess I'll find out (15 lb AUW biplane). Actually, I read that the P160 will accommodate 12S on a 19x10 APC. I bought both size props, but am leaning toward the 12S setup. Thanks for pointing out that the P160 would not be suitable for the new Hangar 9 Pitts.
