I got the 2820-950 for my 3S and 14x7 here in Denver. Hope it pulls well and it did balance fine. I am using TP 2250 65C packs and they did not present a problem either.

Cool. I'm sure you will have plenty of power with that setup. Looking forward to seeing it fly.

There are many different ways to setup a plane for sure. I was just inquiring if you had the actual data or if you were just going off from the site specs. I am just curious what your setup is and if you easily get the correct cg. The 2810 is a little heavier than the other motors most use. I really would love to see this plane fly with 1200 watts.
^^^^^^^^^^^^^^^^^^^^^^^^^^
I will see if I can get some video for ya. Sorry for being short but with the weather what it is and all the BS thats been happening on RCG lately its hard to stay in good spirits. Speaking of spirits, Im a lil better now

Awesome. I hope you get some flying in. It always helps calm me down after I get worked up about something.

Bear in mind that watts in = watts out, so if someone is throwing 1200 watts into the system the likelihood that the power is actually going to the prop is extremely low (so a low efficiency). Whats going on likely is that more watts is being transferred to heat instead of the prop, while this isn't necessarly bad its not the best and the motrofly motors are some of the best when it comes to efficiency. People often up the prop size 1in and seemingly find out that they are getting the same run times.


Since amps = heat most people don't recognize this and just go for a high amp high watt setup while missing the most important thing, prop RPM. You really want the highest RPM you can get out of a prop size as you will develop more thrust. I've tried to figure out what RPM's the omega 130g gives for 3s and 4s prop setups but I haven't gotten and answer.We've been talking about prop and motor setups over in the extreme flight power systems setup and we seem to have nailed down the ideal combo for the 48" planes. Thats a custom wound 2820 down to 600-625KV motor on 5s with a 13x7 xoar prop.

That setup is good for about

750watts
43amps
9500rpm

It seems to work really well

There are some heathens that think a 683 14x7 4s setup is ideal also

Sweet Cannon bro!!!!! And Colorado trails, wooohooo. I use to race GT mountain bikes. Had an Avalanche hardtail decked out, a sweet 4000 full suspension for the big drops and freestylin, and then my speedster/pride and joy that won me two series championships....the team GT Zaskar LE completely done up right (for back then) with Sid air fork, Chris King headset, Bontrager bars, all XTR components except the carbon cranks and clipless pedals. Yea those were the days bro. Now at almost 50 years young I can still run with the big dogs but have to sit on the porch a little longer afterwards

Picked this one up recently on here, thanks very much, nib for a lil more than the new ones but thats the price you have to pay if you wanna play. I have V2 71 slated to be on the table soon. Oh and the 2 meter Osiris absolutely has to find its way into my trailer at Toledo '13
BUT if I could get my hands on the 89 SHP, everything else would have to get set aside for a minute

Yeah man, I will be 49 next week, but still get out and get it done. More "porch time" afterwards but what the heck.

Looks very stout. I know what your saying about the whole efficiency deal. Like I said above there are many different ways to setup a plane. I am just curious as to how that setup flys. I am very happy with the setup in mine and don't see a need to change it.
I am running a custom wound 2815-1025kv on 3s 2200 through an ice lite 75 on a 13x6.5. On fresh packs I get about 650watts at 58amps. Seems to suit the way I like to fly this bird. My motor and esc stay pretty cool but it warms up the batteries a tad on those hot days. I don't usually fly super hard but I gave her some juice in this video from last November. I have some newer packs that have had a few cycles now. I should give her another hot supper one of these days. See how hard I can push her with a little more experience under my belt.
