View Full Version : What Outrunner are you using on Eflite Yak54?

What outrunner are you using on the Eflite Yak54? I prefer HiMax motors, because my local hobby guy stocks them, but wondering what everyone is using.
The model recommends a Park370, but I really think I want more power than that, since I will be 3D'ing it.
To be honest, the outrunner motors are "greek" to me. I'm running a HiMax 2816-0890 on my Mini Edge 540, with enough power.... still could use just a little more for vertical power, but plenty for aerobatic flying.... I'm sort of a power'holic..... but with the foamy's you run into a power vs. weight thing....
Anyway, I'm rambling..... what do you Yak54 flyers think I need to use???

Can anyone help me????
Really a way to determine what motor vs. size/weight plane for 3D'ing would be great !
I just started messing with the outrunners, so help would be very much appreciated.
Have accumulated 7 outrunners somehow or other. Most of them are Esskay (or MTM, I think). First two were 400F's from Dymond Modelsports and one swings a 6x4 nicely on my Multiplex Easy Star. Batteries are GP1100 nimh's. The other 400F is geared and powers my Multiplex Easy Glider with a 12x8 prop on 3 cell lipos.
On my 3D birds, all under 16 oz., I like my 400XT's from Hobby Lobby ($30 when on sale). Direct drive 10x6 HD prop on 3 cell 880 lipos gives good duration and performance (my brain goes into melt down after 10 minutes of 3D stuff). Have 3 of these motors.
Under 8 ounces I use Little Screamers, amazing little motors. Swing a 9x5 HD prop on 2 cell 1300 lipos.
Also have 2 brushless that are not outrunners. One direct for speed (Mega 16/15/7 on a Simple 400) and one geared for power on a GWS Formosa.
Have been using Cool Running's controllers after experiencing problems getting the CC controllers to handle the outrunner style motors.

My problem with outrunners is that it seems every manufacturer uses different numbers to describe the size of the motor. I have a Hacker A-30 but and Electrifly might have 8 numbers to describe its A-30 sized motor. Being used to glow engines a .40 is a .40 and a.25 is a .25. Why can't they just standardize or am I just to dumb to understand?

No Standard.... hey Bobby, that is definitely the problem. Thanks for your input.
Thanks RonJ for your input also.

I used two of the Torque motors in mine. The first was a Torque 26T (http://www.atlantahobby.com/shopexd.asp?id=5363) and TP 3S 900. Great performance. The second was a Torque 22T and 3S TP 1320. Ballistic performance, but a bit on the heavy side.
Here is a 3mb video with it on the 26T (http://epowerflight.com/Media/sample/Parsons-QQ-YAK2.wmv)

We flew the AXI 2208/34 for a while, a bit short of amazing. Went to the AXI 2212/20... WOW. Now that's a motor to go ballistic on the Yak54. With the APC 9x3.8, draws 18 amps, 195 watts and 34 oz's thrust. Very cool... :cool: . Needs a 1500 mAH 12C or better...
