From tlhe specs it doesn't look all that great!

The Park 450 is ideal for 3D park flyers 15- to 25-ounce and scale park flyers 20- to 30-ounces using 2S - 3S 1200–2100mAh Li-Po battery packs.
It will provide sport 3D performance for a Mini Edge size plane and great performance on the new E-flite P-47.
I just don't see how 18A for 15 seconds is going to provide 3d performance on 25 oz edge!!!
I wonder how it would compare to the AXI 2212/26 on 9.6v nimh or 3s lipo? Thinking about swapping out my AXI with this motor in a GWS PT-17 to add a little more "positive" forward weight and lose a few pieces of clay in the fake radial.
Also, I know Eflite motors come with male connectors soldered on, but do they include matching female connectors in the box too or do they just assume one would use an Eflite esc?
If you are going to keep it at 12A or so, only the smallest of those props will be safe - since it is higher Kv than an AXI 2212/26 (by the way, you'll see it weighs over 1/2oz (15g) more) it will draw more than the AXI - an 11x3.8 APC SF on an AXI draws >15A, a 12x6 APC E - I didn't dare try it, but it'll be a lot more than that.
Be careful out there.
Park 450 in a Formosa
I mounted one of these in my Formosa using the E-flite stick mount. Needed to remove about 3/4" of the original stick length to be able to mount the cowl. Had to mount the receiver over the servos and slide the batteries all the way to the back of the compartment to balance. Using an E-flite 20A esc.
On 2s packs (PQ1100, PQ1800, and TP1320) with a GWS 1060 HD prop, performance is much better than the stock 350 with C gears and a 9x7 and duration is about the same (9 minutes timed WOT). Packs stay cool to slightly warm.
On a 3s TP1320 (my only 3s pack so far) with the 1060 prop, AUW is 15.25 oz. and the performance is amazing! My first truly "unlimited vertical" setup. I've only flown this pack twice so far, mostly 1/2 throttle with only a few "punches" to test out the climbing ability. Recharging after those two 9 minute flights put about 600mah back into the pack.
Sorry I don't have any way to measure the amps or thrust, but I'm very pleased with the performance of this setup and nothing seems to be over-taxed.
