RE: New Electric Partner
Thanks for the comments. Regarding the bullet connectors, yes...they are 4mm. I have larger ones but they're quite heavy. I've used the 4mm bullets on all my C50 motors for quite some time and have had good success with them. The Partner is the first model in which I've used an external arming connector for the motor....a nice convenience I'd recommend to others. While some folks have decided to utilize lithium cells and regulators for receiver/servo power, I'm still quite comfortable using NiMH, which I've used with 100 percent reliability since perhaps 1990. Pack voltage holds up well under load and weight isn't an issue for my Partner. Based upon what I read, lithium cells and regulators seem to provide good reliability for those using them; however, the combination does represent two potential failure points.....the battery pack and the regulator, while a single (but admittedly heavier) Nicad or NiMH pack represents only one. Consequently, I've decided to stick with that which has given me good and reliable service for many years. I think it's great that pattern flyers now have several motor choices....both outrunner and geared. It really comes down to personal preference as there are several good combinations that can produce winning results. The 13 wind Hacker C50 is a good motor for those who don't want to run a larger (i.e., 22 x 12) prop. I don't own one, but unless I'm mistaken, I believe the C50 13XL is Chip Hyde's favorite of the Hacker geared lineup. Wolfgang and Roland Matt used the 13XL when they first tried electrics and had good success. However, more recently, they have switched to the Hacker 14XL C50 competition motors and ESCs. I have a 12XL on an Extreme Flight Yak that turns a 20 x 13 APC at 6000 RPM while drawing 68 amps at wide open throttle. It goes like a rocket and climbs like there's no tomorrow. It's all a matter matching the motor, prop and battery pack....there are many combinations that will work. One of the primary reasons I continue to use the Hacker C50 motors, which have been ultra reliable for me, is the sound of the gearbox. The motor is quite quiet in the air, but the gear box does provide me with some audible feedback which helps establish the position of the throttle. I do not, however, have anything against any other motor type for those who prefer something else. I probably should not have even mentioned adjusting the wing incidence as I wasn't really trimming for good pattern performance, but experimenting to see how sensitive the Partner is to changes in wing incidence. I didn't have an allen key in my flight box that fit the stab adjusters so I decided to see how changing the wing's incidence would affect knife edge and the slight up trim needed to compensate for the zero/zero setup. As it turned out, a few turns of the wing adjuster screws made little difference. I won't begin the actual trimming sequence until the LiPo packs are broken in and I can use them as I would during a normal pattern flight. At that time, I'll assess the Partner's performance relative to knife edge flight, as well as vertical ups and downs, and then make adjustments accordingly.
