While we're talking electronics put almost 2 batteries through my King 2 today, seems to be easier to hover than my Falcon 40! but alas, near the end of the second battery it found the ground at a less than optimal angle, shredded the stock blades. Upon doing damage assesment at the bench I noticed a very slight wobble at low RPM, seems to go away the higher the RPM, bent main shaft I'm assuming? Also, if I slowly increase throttle after 3 clicks or so RPM will not increase until I get over half throttle, then it jumps up to where it should be and works correctly to full throttle, if I reduce power to almost off and increase again it increases RPM as it should in relation to stick position, but if I shut throttle down, and start it again I get the "dead" area again, seems to be betwen 1/4 and 1/2 throttle (Esky brushless motor and ESC), did I kill the ESC?


You got a bent feathering shaft for sure....I know that. The motor problem...I've found very poor soldering on the connectors on E-Sky motors, and they use steel wire. Strip the shrink tube off your connectors (motor side) and see if you got bad solder....that's what it sounds like...broken wires on the connectors.

I bought the esky 3800 about 6 or 7 months ago.I ran it a couple of times and didn't like it,so I pulled it out and installed a alpha 400.Great little motor for the king,and if memory serves,it's cheaper then the esky.Since the 3800 is sitting in my parts box,I believe I will pull it apart and check the connections,and resolder if needed.When I had it in,it just didn't seem like it was spooling up all the way.The alpha on the other hand,(using the same esc)has been flawless.Smoother,and mucho quieter too.Very nice cheapo motor.Vic,I looked up the HDX450's.I like,and I will buy a couple for my 450's.320 plus watts for not much,yeah,,,,that works fer me.

Chief...I had the 3200kv...it was fine till "I" runied it. I bought a 3500kv to replace it for the MX-400. I bought the 3800kv for the EXI-450 (and another ranger fuselage...LMAO). For the money....you cant beat the quality and reliability of the HDX motors. I heard the Alpha's were a POS. I had one here on a repair job, the mount screw holes (all 4) were stripped right out...metal is too soft...yup, POS.

Well, I'm very good with soldering and circuit boards, with the symptoms it doesn't really sound like a bad solder joint to me, but I'll get out my VOHM and check it to make sure.


You wont need a meter....if they're bad, you'll see the broken strands. The steel wire breaks with vibration of normal use. I'm running an E-Sky 3100kv on my GWS Corsair. Every so often, I have to re-solder. The good part is, if I have a bad connection on the motor....the Pheonix 25 will tell me by the volume of the bootup signal. If it's weak/low sound...I got broken wires. If it's strong and loud....all is good. Yeah...my Corsair is WAY over powered but it will fly like a rocket vertical (LOL). Been waiting for it to EXPLODE under the pressure.

Yeah,the motor mount is kinda soft,but the damn thing runs just great in the king,tons of power too.Did you get your exi 450 yet? I'll be ordering another one maybe this week,along with some other parts etc.I'm also gonna get the heliartist H500d fuse(unpainted),and maybe a 58 fuse too.As much as I didn't like the real ones,the 58 sure makes a fine scaler

Hey,
I read your post and checked my setup. HAVE THE SAME problem(free load without pinion on the shaft) also motor starts vibrating a bit at that dead area. all things are stock, just 3800+esky esc. I checked with 3100 (again free load) no problem at all.
Please let me know if you figure it out

I expect the EXI 450, telebee gyro, motor (hdx 3800kv), esc, fuse, servos, and the DX7 this week. I did buy two AR6100E's, one for each heli (love that DX7). The 58 makes an EXCELLENT scaler. It's light and easy to mount. Barely notice there's a scale fuse on it. The 58 is the apimity of KISS (keep it simple stupid). The more simple, the less that breaks, the easier to fix if it does break. As for now with a heli down for parts, I'm flying the pi$$ out of the GWS Corsair (LOL).

Status: offline 		now you guys know why I stopped stocking esky brushless motors a long time ago. I have found at least 3 motors that are better for the same price and two that are the exact same thing for $10 bucks less just under a different name, lol. I recently tested the tonic-x motors on the king, the dragonus, and the shark and all three I tested performed flawlessly. I swapped each motor from bird to bird and it seemed to make little difference on these motors as far as load was concerned. Temps stayed low and flight times were pretty decent, I would say for the price they are decent little motors. I am also a very big fan of the danlion for the king, once again for the money they are really hard to beat. I think though that more attention should be paid to the esc than the motor, it has been my experience that you can get away with a crappy motor/good esc but you cannot get away with good motor/crappy esc. For the money I personally do not think you can beat the hobbywing 30a w/ ubec, the waypoint 25a or the danlion 33a, they have consistently given excellent performance and reliability and none of them run $40 bucks so you do not have to spend a fortune to get good reliable equipment.

yes you can usually install the 11 tooth and thats what most end out with in the 3800. The 3900 I found actually lost a little headspeed with the 12 tooth and the 11 was still a tad too high only because the 3900 lacks the torque of the 3800 at full half stick to full stick. (RPM actually dropped off a a few hundred rpm according to my tach).
so you may want to stick with the 3800 and 11 tooth and do little to mod the frame (if anything). Don't know if I mentioned it but those frames due crack right behind the motor (hard landings) so you might think about the frame stiffener from Xtream for about 11$ which also acts as a heat sink and motor mount reinforcement.

Status: offline 		Thanks Betapilot, I'm leaning toward the ESC as well, I believe I'll take your advise and swap the motor/ESC, now I just have to start learning the motor differences, 3200, 3500, my brain still hurts from trying to learn how to fly! Will I get comparable runtimes with the Danlion combo you have on Castlerock?
