I went back thru my telemetry logs and without my gimbal and camera mounted, the best I've seen with the KDE's 515's is 10.5 grams per watt . My old Tiger MN470's, best was 10.8 gpw.

9.6 to be exact, do you think if i go to the 3510 475kv's would it be worth the effort? I have been focusing on so many other things, and did'nt realize how far off the efficiency numbers are. The thrust and amp draw are real close. 22 min's on 4S8000mah no lower then 3.7 under load with 3 axis...

I have those motors and with out my camera and gimbal, she hovers at 3.5 amps per motor at 2120grams. Loaded with the gimbal draw, 3.8 to 4 amps 2515g. those KDE spec's are with tmotor cf's. I am running 14x4.8's:tennis:

Ferdinand, Have you seen these?:tennis:

Chuck, Your right, with the increase in voltage and efficiency it looks like i will gain a minute or two of flight time changing over to my 6S with 12x5.5's or 13x4.4's. My lipo's both have same per cell weight. Now to balance up some props. My AUW with the 4S is 2515g and with the 6S it's...

Chuck, If you are not going with the KDE esc's, go with the Castles, trust me. They work flawless with the SuperX and the KDE's.

Here's a quote from Chris at KDE. "Motor temperature information. Windings 450F Glue 450F Magnets 356F Bearings 300 to 350F oil bakes out All of this technology carries over from us producing very high end RC helicopter motors. Those motors get abused at a level that is so much...

Great, hoped it would help out. Let us know how it works out.

John, What's your AUW going to be? Reason I ask, as you might be better off with a 4S, just look at the prop spec sheet. I've run those motors with 4 and 6S, and with 6 515's on the 4S gives you a total 3,810 grams of thrust with 14X4.8's at 50%. By the way, Kde's thrust and amp draw spec's are...

Between the Kde's 515 kv's, Castle esc's, and the SuperX, I couldn't be happier. Flies really good, 62% hover with 14' Tiger cf's. Aerial mob booms end to end are 13.5 inches.

Absolutely! You won't be disappointed. Excellent customer service, here in the US, and always happy to answer questions.

Sold a vintage Hiwatt dr103 for triple what i paid for it after recap, did this Mesa boogie last year, leaking caps, owner was all smiles. Most of those vintage collectors don't play worth a cr*p, so they wouldn't notice bad sound anyways...

I recap vintage tube gear on average every 10 to 15 years max. 30 hours is unrealistic.

I would use these:http://www.rcdude.com/servlet/the-1497/Hyperion-Gold-Bullet-Connectors/Detail This is what i'm using now, I just solder a new one when they start to show any signs of weakening: http://www.rcdude.com/servlet/the-1800/Castle-Creations-5.5mm-Bullet/Detail

Mine laughed when i showed her the video, She's like don't get any ideas. Safer to strap it down when testing, that thing could injure her in a heartbeat.

That's great news!! Monroe county parks seem to not have a problem here either, 3 or more flying on any given weekend.
