<u><span style="font-size: medium">LIST OF:</span></u><span style="font-size: medium"> INEXPENSIVE MOTOR,FOR 50-SIZE PLANE: Suitable for 16x8 prop, and 5S LiPo
</span>Here are some motor choices that will perform very similarly to the Hacker A50-14 S. They all have a Kv close (-ish) to 420, and weight around 345g.
Let us keep in mind that <span style="font-size: small">the Hacker A50-14 S costs &pound;114.69 (in the UK).</span>The Hacker has a 4025 stator, and is ~5055 in external size (i.e. 50mm diam and ~55mm long).

-Here are the first 8 -there are probably more motors out there than the ones I have found, but I have found enough of them:</p>

4. Turnigy G46 Brushless Outrunner 420kv (.46 Glow), 300g, D50 L55
-Probably not powerful enough, is only 300g -similar to E-Flite Power 46 but with a lower Kv (-and is 30% of price of E-Flite ...)
$47.84 = &pound;31.49 - http://www.hobbyking.com/hobbyking/s..._46_Glow_.html</p>

5. Turnigy SK3 5055-430kv, 370g, 12T D50 L 59
-Really excellent motor, made in Sunray factory along with Hacker, Hyperion etc. Has almost identical internal parts to these. Seems very similar to Hacker A50-14 S (except has 4030 stator, and is slightly heavier). Has very good user comments: "... run a 17x10 TGS prop at 6690 RPM. The static traction is 5 kg"; "using a 18X8 Xoar prop w/ 6S5000 Turnigy 40c batteries and this is the ticket. Over 5900g thrust at 79A is good for Osires 62 ..."; "... The plane used was a 3D hobby Shop 70" AJ Slick weighing in at 9.25 lbs. Excellent performance (with this motor) as noted above ..."<span style="font-size: small"> -This motor is 28% of the price of Hacker A50-14 S ...!

6. Tacon Big Foot 60, 420g, 400KV, D50 L 65-this motor seemsvery similarto XYHN 5065, andmay well be made by XYH.
-Has right Kv;75g more than Hacker A50; is 65mm long;is 40g more than E-Flite 60 -SO THIS TACON 60<u>NOT</u> IDENTICAL TO E-FLITE 60
