Making America Fly Stunt Again!


« on: June 12, 2017, 03:20:49 PM »

I just rolled the dice and bought a few of these motors on ebay after consulting with a few notable e-guru guys whose opinions I really respect.  They told me it compares favorably and is possibly/probably a bit nicer than the Arrowind/Emax 2820 as sold by Brodak. (yes, un-verified performance claim, but is based on good recommendation and evidence).  

Waypoint motors were sold in Singapore branded as Hyperion.  Their origin seems to be Sunray Technologies in China who make many of the well known brand names like the Hacker and many, many others.

These should be able to power anything from a Twister, most 35 sized classic ships of a reasonable weight, up to a (light) Pathfinder or Cardinal.

I figure for the price...and the intended use,... I can't go wrong.  I made an offer of 10.00 and it was accepted.  
So I bought 4...  With shipping it was only $50.59 for 4 motors.

Let us know if the bearings are any good in those motors.

     I am using Hyperion motors in my profile carrier plane. I've gone though 6 of them because of the lousy bearings in them. Why I have used so many motors is that the bearings spin in the case so that ends the motor. I tried glass bearings and nothing changed, 2 or 3 motor runs in competition and they were shot. Might be that the cases were machined wrong because the bearings seemed to be loose in the case even when new and not run yet. Now they no longer even make the motor that I used or I would still be buying them, very powerful motors (HP-HS3026-1400KV).

It's KV is 988.  My Cobra is KV 930 and I run it on 4 cells set to around 9K rpm.  Looking at the prop chart it only talks about 3 cell setup.  Are you going to use it on 3 or 4 cell setup?

You do get what you pay for, not saying these won't be good motors but I have a Scorpion 3026 that I lawn darted about 3 inches into the ground on a RC plane, all I had to do was clean it and replace the front bearing, that was 5 years ago and the motor is still running flawless.
