Some people on the RC groups were speculating that these motors are assembled/made overseas such as China. In other words, R&D is in the USA, but farm-out the manufacturing elsewhere. Is this possible that some motors come from overseas, or do they hand build ALL the motors in the USA?
And yes this is what i was speculating that Astro had just become a china depot and most of their motors were being outsourced. I saw no way that astro was competing in the RC market with the chinese invasion of fast and furious (and almost forgot cheap) rc brushless motors.
So the new owner of Astro saw an advertisement for a businss for sale Astro Flight Motor two years ago in a business journal and it was obvious when he bought it that Astro was on its last legs in a small decrepit location and only 5 employeess...it seems logical that most buyers would resort to outsourcing and putting more affordable lesser quality motors on the market to compete with turnigy, etc.
According to the folks at Astro this is not the case, that no astro motor or even any part of an astro motor is being outsourced..its all being made here. I saw for myself small 1 inch can motors being assembled on a work bench. I counted 4 full time workers winding motors.
The new owner said they were not doing near enough volume to make outsourcing feasible for them, plus they were trying to build on the Astro legacy of quality.
He showed me the laminates used on the 3220. He claims his cost on the laminate is over $100. and its done by local US company. He attributes quality laminates to the efficiency of the motor. He showed me in comparison a much cheaper laminate of a chinese competitor rc motor and it was obvious the Astros laminate were a finer nicer grade. He says the laminate in the 4 inch motor costs him 400 dollars to make. Also the grade of copper used in the 4 inch motor is even higher than on the 3220's etc. The 4 inch motor is being made for a customer where money is not a concern. My guess is that would include a pilot for a sailplane, and the military. It would also make a great electric bike motor but you are #1 going to need to be crazy as in LFP and #2 willing to pay big dollars to save the 20 pound difference or so between this new astro and what lfp is using now. Also i think what guys forget to calculate with these sexy motors is the weight of the gear reduction unit itself. A matt gear reduction designed for this motor is probably going to weigh 10 pounds or more. Also dont forget to factor in the cost of the gear reduction (in very small production) when fathoming how much all this is going to cost to put the 4 incher on a bike.
Also remember that these sensorless RC motors, need to be run at their sweet spot to be efficient. That means this motor will have to run at 6000rpm is the number they mentioned. Think about having to run a motor as powerful as this at those kind of rpms for any extended period of time, and a mars motor or perm motor starts to look a lot more attractive to the rc bike builder who wants power and smoothness. The 4 inch motor was designed for high powered flight...not cruising around on 2 wheels.
Putting the 4 inch astro on a bike is way way far fetched. But I really would love to watch if someone is going to try it. Mabye a trike would be more safe and sane
....or maybe the military is looking for a manned electric bike to go on "stealth" missions behind enemy lines on the ground. Wouldnt it be funny if it was the military that became the first entitiy ever to put in an order for 1000 motors for an electric bike project. By the way the thing that was posted earlier about md0007 saying he could have bought 1000's of astro motors for his bike project....what electric bike ever sold 1000 units? A high priced astro powered bike is going to be the first one? Also way way far fetched. Astro minded people on this group..i love this place
. Down with the drones and steal their astros!! lol
