If you look at the 2212-6 at bphobbies, you'll see that it is listed as 220-230 max watts. They indicate that on 3s it pulls 21amps at 232w with a 5x5 prop. Those are basically the results we achieved.

If you look at the 2212-6 at rctimer, you'll see that they list it at 342watts. I think they are "overly optimistic". The list the 2212-6 with a 30amp esc. They also list the 2826-6 at 342watts...and suggest a 40amp esc.

Be careful in trying to get 342 watts out of these motors. Most motors are rated for a max amp draw. You might damage the motor and/or worse.

With all this said, we were testing the motors with the black 6x4props also from rctimer. I think you will get better performance with an apc. In looking at the two props side by side, the apc looks like it has more teeth.
Mine was the 2826-13, and I noticed that after a few seconds at WOT, (20A+), the motor got very warm very fast. I'm using it on a 2M sailplane turning an 11x6 Graupner folding prop, so I am pushing it so a little heat is to be expected, (I only run at WOT for 15 seconds or so at a time to get to altitude, then shut down to soar; the motor has time to cool a bit that way). That being said, compared to the Rimfire 28-30-950 I was using on that plane, the 2826 has a very noticeable increase in power when compared to the Rimfire; but it is not a 30A motor, (as rated in their website)! Good motor, and I'm very happy with it's performance, but they need to clarify the stats on the website.

Sorry to hear about your lost plane...

I've got the exact same set-up in an RCPowers F-22. My 2150mAh Rhino's should be at my door any time now. I'll do some serious bench testing before I use the 30A ESC and 2826-6 motor in my plane. Maybe I'll run 5 or so full cycles through the equipment before mounting.

Although it is just some depron, it would be a shame to loose any of the gear...

That's a great motor! How do you like it on your Yak, and what prop are you running it with?

3530

I'm not going to put it on my yak. The yak is going into retirement-just not happy with it no matter what I did with it or how I flew it. It it a good plane it just isn't for me. I may put it on my daily flyer-Extra 330. I beat that plane up and it takes all and then floats down for a soft landing. I have no problem flying it in 12mph wind. The other plane might be my Funtana X. I just burned up my omega72g trying Lovemak. I flew about 30 flights got comfortable then on it's KE full power L-rudd full down cavatated prop for about 6sec and motor died. The RC Timer 3a 5v UBEC landed the plane safely. But the RC Timer 3530 has so many features of more expensive motors I doubt I'll ever buy anything else. My pics really don't do this motor justice. You just need to get a couple. After new year I'm going to get at least a few more. I'll post more results later on the other stuff I got.

It looks like RCTimer did a great job with shipping. Only six days from the factory to Kansas City. Sadly, it appears the post office has lost my package somewhere between Kansas City and Webb City. Who would have thought you could lose a registered package! I'll give it a few more days before throwing a fit with the post office.

Thanks for the fast shipping Nina!

72g

Gonna have to. It was my fault. I put a 12x6sf on it. But I honestly believe that sooner or later it would have failed-the windings are that mashed up. If I had a 11x5 on it I would in a heart beat. But get this. While waiting for a motor mount for my RC Timer 3530, I put an old Super Tiger .10 in the mini Funtana X. All I can say is WOW! I'm beating that thing up like I own it. Easy landings too. I hope my RC Timer 3530 1100kv will do better than the 72g. The 3530's windings look taller-about the same dia. 72g weighs 71.4 and the 3530 74g. I think as long as I stay under E-11x5, I should be ok. Any suggestions on wire size & turns?

Just got my shipment from RCTimer and it only took 10 days maybe a little less. I'll be getting more from them especially the Deans connectors w/ the "grips"

some handy advice on those xti connectors.... lightly sand the solder contacts until the shininess goes away (with maybe some 400 or 600 grit) and then clean with alcohol for a much faster flowing, consistent joint. a puff of powdered graphite lube on the blades and in the female connectors helps with the tighter fitting connectors. (plus its conductive!)

I always clean every contact needing solder. Electronics components often have a film of oil left from the manufacturing process, and if not cleaned off, solder won't flow or attach till the iron gets it hot enough to burn it off, (at which point the component is dangerously too hot!). And, be careful with graphite; it's slick stuff for sure, but it's carbon...it's conductive!! Vaseline works really well on "T" style connectors and is non-conductive, (makes pulling them apart very easy).
