B.L. setup for Slow stick? What are my options?


My Dad might get a slow stick. What Brushless setups are you guys using witht the SS. I would prefer direct drive.

Motor ?
Prop ?
Batter ?

Thanks!

I don't think the slowstick will fly very well direct drive, unless you are
talking about an outrunner. It needs slower speed and higher thrust.
Here's my setup:

Motor: Himax 2015-4100
ESC: CC Phoenix-10
Gear: GWS 300C-D 6.6:1
Prop: GWS 11x8
Battery: 3s 1500 Lipo (8C)
Gearbox adaptor plate: CNC plate from Bishop Power Producst or All eRC.

Goes vertical and I get long run time since it only needs about 25% throttle
for cruise.

There are several outrunner options out there. Keeping within, or close to, the max amp ratings for the motors:

An AXI 2212/34 with an 11x7 HD prop on 3s will get you almost 23oz thrust at 8.7A.

A Nippy Black 0808/98 with a 10x6HD prop on 3s will get you almost 16oz at 8.7A. [see photo of it on SS fuselage with prototype mount - Jerry Blake has now made available far better ones]

A Nippy Black 1812/100 with an 11x7HD prop on 3s will tear the wings off a SS! 32oz thrust at 20A!

The first two of these could be run on something as small as a 3s Apogee 830, any of the mid size Tanics, iRates or TP would get you 10A with no trouble. The 1812 is going to need 2000+ Tanics or Generation 2 TP's to get the rated 18A max.

The PJS line has several motors which would be okay (500, 550, even 1000), though some people seem to have had issues on quality with them.

Cheers, Phil

Thanks guys. I'd definely like to keep the amps down around 8 if I can.

Dad will want some decent power and good flight duration. I'm not concerned about crazy thrust since it is a trainer.

What SS airframe specs are you using in moto Calc?

im also using the nippy 1812/100 with a 3 cell tanic 2200 and a 10*4.7 prop. using the lowest timing on my esc i might be at around 10-11 amps works really well. vertical but not to strong. good climbout at like 70 degrees

Mine flies well with an Astro 010 BL with the 709 (3.xx:1 ratio) gearbox, a 10X4.7 APC SF prop, a CC Phoenix 10 controller and a 3 cell Lipo (I'm using Kokam 1500 HC).

It has plenty of power -- but of course no speed, its a SLOW Stick after all. It will loop well and sometimes it can get inverted and stay there for a bit, but that seems to be dependent on the type of wind that it finds.

The thrust line will need to be a few degrees (3 to 5) down and about the same number of degrees right to make it fly smoothly with this setup. With no camera on board this setup will fly the Slow Stick for about 45 minutes at speeds that will let you learn to fly safely and smoothly.

Kyle - I would be surprised if you are only pulling 10-11A max with 3s and a 10x4.7 (is that an APC SF?). I haven't tried that prop on the 1812, but on the 0808, a 10x4.7 APC SF pulls much more than a 10x6HD - and on 3s [3600 E-tec] a 10x6HD on the 1812/100 draws as much as 15.5A (164W) - 26oz static thrust! One can assume that a 10x4.7 would pull even more!

Cheers, Phil

ok its a 9*4.7 my bad im using a 10*4.7 now and thats around 14.5 amps static. but the 9*4.7 with 3 cells and the lowest timing on the esc was around 10-11 amps last time i looked. i could try it again if you still skeptical. btw im using a CC phenox 25 amp esc with the LOWEST timing which is more efficent i think.

I run the 10x4.7 SF APC on the 0808/98 with 3S Kokam1500. I'm using a Phoenix 10, and never hit the overcurrent protection..

He he he..
Just installed a Nippy Silver 400 on my Slow Stick. It won't be slow any more.. 8xKAN950's and a 10x4.7 APC slow fly prop, 23A static @ 7.1V.. Need to remember - don't use full throttle.. don't use full throttle..

slow stick brushless


I made this brushless with a black and decker mixer armature and sonicare toothbrush magnets. 5 amps 18 oz thrust 3 lithium ion laptop batterys 1 hour
at cruise. 13X6.5 GWS SF It will hover the slowstick but not quite climb straight up. It will fly inverted at WOT.

I use the Nippy Black 0808/98 with the APC 11x4.7 sf prop and TP2100 2's Current is less then 8A flight times are long as most of the flight is 1/2 throttle. It is light weight, floats very well, fly's inverted all day long, has more then enough power, very quiet. In my opinion it's the perfect Slow Stick setup!!!
