| For nearly 2 years we've been flying a Pantera 50 powered by an OS61SX WC engine. Thanks to the massive clutch, and humongous bearings, this rugged Pantera 50 has flown, and flown, and flown . . . with no failures whatsoever! Along the way we learned the stock 8.7:1 gearing works great with a 61 or 70-class engine because they like lots of RPMs, just like a 50 does. Aso, it's worth knowing that physically, all the big block engines share the same external dimensions, i.e. the OS 61SX, 70SZ, and 91SZ as well as the YS61ST2, 80, and 91ST and 91SR will fit). This means all we change for the 61/70 engines was the engine mount and the clutch hub, what we call Stage I. Next we've replaced the 61 with a YS91SR, yes more than 3 horsepower in a Pantera 50. Then we set out to beat on it some more to see what, if anything would break. However, when we go to an 80 or 91 class engine, the gear ratio needs changing - no surprise. Determining the "right" gear ratio was pretty easy actually (yeah right, and if you believe that we have some nice oceanfront property for sale here in sunny Florida). Anyway, instead of a 10T pinion, and 87T main gear 1, we ended up with an 11T pinion and 86T main gear 1. The resulting 7.82:1 gear ratio, which is perfect for the 91 class engines when matched to 620mm blades delivers awesome results! These extra parts constitute Stage II, i.e. what you see flying in this short video. Stage III adds a long tail boom and belt, on the off chance you want to experiment with longer blades - up to 710mm. As for us, we think the stock boom and 620mm blades are perfect, but if we can lay hands on some 640mm blades (they'll fit, no problemo), we think it may be interesting. Anyway, enjoy this folks. | Broadband Connections | Dial-up Connections |
| Ever wonder how well a completely stock 50-class heli can handle when pushed? Will it fall apart in the air? Kyle Stacy (he finished 14th at the 2007 XFC, so we're talking about a seriously good pilot) thrashes his Pantera 50 in this clip. What's more, Kyle's Pantera 50 has no options whatsoever . . . yup, it's got the stock urethane dampers, stock paddles, etc. Powered by an OS Max 50SX Hyper, using a ProMuffler and burning Power Master fuel, it's got a Youngblood governor and Radix blades, and is controlled by an inexpensive Spektrum DX7 radio with JR DS8311 servos. This is what the Pantera 50 is capable of without resorting to bling. | Broadband Connections | Dial-up Connections |
| Kyle Stacy turns it up a notch as he has slightly modified his Pantera 50. Yes, he's spent big money on bling (yeah right) by installing the optional 3D flybar and some harder urethane dampers - did you really think you needed to spend big money to really abuse a Pantera 50 with hard 3D? Once again it's powered by an OS Max 50SX Hyper with a Curtis Muscle Pipe on Power Master fuel, a Youngblood governor and Radix blades, and it's all controlled by an inexpensive Spektrum DX7 radio with JR DS8311 servos. Yup, it's pretty sweet! | Broadband Connections | Dial-up Connections |
| What if you're a pretty good pilot in your own right, but you didn't get invited to the XFC? Will the Pantera 50 fly sweet for mere mortals? Dave Playfair flies this Pantera 50, with Kyle Stacy's exact DX7 radio settings and proves you don't have to spend big money to fly 3D - Dave's a pretty good pilot also! Below are Kyle's settings . . . | Broadband Connections | Dial-up Connections |

Kyle runs a linear pitch curve with 0 degrees pitch at 1/2 stick in all modes on his Spektrum DX7
