Has anybody got any numbers or first hand experience with this motor???
I am building a new profile and am considering using it...MotoCalc shows
it to be good for about 45 Oz's of thrust at 25A on a 12X7E prop using
a 210O MA 3s lipo...Any comments???

There has been criticism of several of the PJS motors - shoddy construction and overheating being two of the culprits. Check in RC Groups forums for opinions before buying a lemon. I have an 800E and its okay, but gets pretty hot pretty fast at anywhere near its rated maximum.

Thanks for the input Dr. Kiwi...I am weary when something sounds almost to good!!!I figure if they are as good as the specs make them look, there ought to be people flying them, or could it be the fellows are trying to keep them a secret???

Thanks

I have three of the smaller, older designs. The only one I've used so far is the 300SF, on my Shockflyer Yak54. No complaints here.

I'm sure price has a lot to do with why the PJS motors aren't more popular, and why more isn't known about them. They're certainly some of the more expensive ones on the market.

Hi Matt:

Thanks for the input and I agree that the price could be a major reason for lack of use with these motors...I might just go ahead and order a 12003D and find out for myself...

I have a pjs 800 and it is bullet proof. No problems at all. I have a 1200 and I have to use 9" props because with the TP 2100 or Kokam 2000 batteries it cuts out before full throttle with a 10x38 or greater.
I am looking for a better motor for a Miracle EPP to use with these batteries. I was looking at the 1000 or 900
Any suggestions?

I use pjs 1200 motor on my minifuntana. with a gws hd 11x7 prop and a tp prolite 2000 3s pack. I get 31 amps 320 watts. The plane has tons of power and plenty of pitch speed. This is the sweet spot on this motor, tons of power and as long as you have some air over the motor(dont use a spinner in the heat) you will be fine. All my pjs motors have been bulletproof(pjs550r,pjs1000, and pjs1200)
3s 2100 prolite will work well too.

I used a PJS 1200 on my mini funtana and it ran a little hot with a 11-4.7 prop. The motor itself produced a ton of power and I've been thinking about taking my Himax off my mini edge and using it again. This motor gave me a ton of power but would make my Jeti 30 amp ESC cut out with a 2000 Kokam Lipo battery sooner then I would like. I think it would work better with the Thunder Power 2100's. I do like the motor alot and again, it produced the power like mad!!!

I just built a miracle 900 and put in the 1200 w/ tp prolite 2100 and it screws... slow w/ 11/3.8 fast w 11/7 but cuts out in a full clinb straight up about 50'into climb and in hand when holding back...I think 11/4.7 is the prop awesome power though
