View Full Version : Giant Stinger needs an electric motor!
06-27-2006, 08:27 PM
I have recently got discusted with my new ZDZ 50cc gas engine in my Stinger. I want to convert it to electric. I have never messed with any electrics of this size. I would like some input into the situation if anybody out there has setup these size planes before. I am currently looking at the big Axi brushless motors with 10 cell LiPo's. Is this the way to go???

Check out the large motors from PJS. The 3D 10000 will fly a 24lb aircraft direct drive with 7400 mAh 10s2p lipos and can swing up to a 24x10 PJS Electric Carbon Fiber prop. The newly released 3D 18000 with fly up to a 34lb aircraft using 7400 mAh 15s2p lipos and can swing up to a 30x10 PJS Electric Carbon Fiber prop.
Visit www.visionhobbies.com (http://www.visionhobbies.com) for more information and videos of electric converted aircraft flying, including the new Great Planes 160 size Ultimate bipe at 16lbs with the PJS 3D 10000 brushless outrunner motor using a 22x12 PJS Electric Carbon Fiber prop.

I've got a stinger 120. That isn't too much smaller than the giant stinger. I located an astro 90 on E-bay for $100. Located a speed control for it for $35. It will spin a 15 inch prop in the 8,000 rpm range. Put an Astro gear drive on it,(about$35), and you can spin a 22 inch prop at 6,000 rpm. I own a lot of small brushless motors, but only astro large motors. They aren't the latest technology but they perform really well , close to a brushless. E-bay has been a good source to find these cheap as people are dumping almost new astros to get the latest brushless. A waste of money in my opinion.

Jerry and Em gave a couple of good suggestions. What is the AUW on it wet? Here are a couple more single motor suggestions, AXI 5330 and BAM 2215 from Neumotors. The BAM 2215 will run on a 12S and give up to around 5k watts. It is a high amp solution though. (opinion alert) To get the matched power of a DA 50 or ZDZ 50, a 12S is needed. Unless it will be flown only for sport or IMAC basic.
You could also go with a Hacker A60 18L, ACRO 90 ESC, ThunderPower 10S3P pro-lite battery and 26x13APC E. for about 2100 watts. Frank has been flying this setup in a 30% BME Edge. He is also flying the A60-14L and a 24x12 prop. This combination pulls 80 amps at around 5400 rpm's.

to convert from 50zdz an actro 60 is enough.
Other motors of intrest is actro 60L, Plettenberg Terminator and the mighty powerfull Predator 10+kw, this might be overkill.
