Yes, not bad at all because I found myself mostly at 1/2 Throttle

Yeah Carlos, and that's tethered...

The actual in flight values should be less...

Paint those prop tips yellow and you're in business!

YES!

Stock ESC as well.

im curious to know how that prop fairs on a otherwise stock system. i really want to swing a 11x10x4 hobby lobby prop and it appears i will need a eflite power32 to go with my 54 amp CC esc that i have in my gear box to make that happen safely. such a shame this gorgeous plane we all have to jump through hoops to fly her the way she was intended to look... with a BIG 4 BLADE!

Tethered, so that's what you call it

Scared me for a moment as I thought the model was going for the camera and tripod!

i thought stock esc was 30 amp? i just ordered that same prop to play with as well. glad to hear about those numbers. i think it might be a winner and ive got the external CC bec installed in case it goes south. i think ecalc was around 66 mph with that prop. not too bad.

It is stock.

I have experimented with the same 4-Blade paddle Propeller from GWS on my other Park Zone Warbirds (F4U Corsair, and T-28) with the smaller Park Zone 480 and it was lower in AMP draw.

I almost installed the Park Zone 480 on this P-47 but, the Propeller Adapter would not reach and I was not going to spend so much time to provide spacers etc...etc...

So, I installed the STOCK Park Zone 15 (950Kv) and perfect!

Scared me too !

I thought she was going to get away from you !

Yes it is. Did I post anything else?

Just in case you all are curious! I wanted to keep the model light as possible to avoid any Tip overs and not cause the Propeller to get damaged but, the model's CG coupled with the Flap deployment allowed picture perfect landing.

Here is a weigh-in comparison of the two popular Park Zone BL Motors in case you are wondering.

The one rating that is highly suspect in being applied to the BL15 from the P15 is that amp number. The P15 is a vastly more robust motor, and can probably deal with heat a lot better than the plastic BL15.

I would guess the BL15 rating has got to be at least 30A, though as it has no trouble on the stock setup.

very happy to hear it is working well! i actually think itsa pretty nice looking prop. paint the center section cross silver and then the tips yellow as mentioned and bam! close approximation. nice work. if the weather holds i might just might get my long awaited maiden on sunday with this bird. chomping at the bit listening too all the great talk about flight characteristics... i think ill go extra 300 prop for the maiden and play it safe. only going to be low 40s temp. are you guys getting shorter flights with the drop in air temps? ill keep the batts warm before flight but once in the air it will be nippy zipping around up there.

Morning guys. Quick question. Is the shaft diameter on the motor for this plane (15BL) 5mm?

I have a 480 motor laying around from a T28 and the p47 prop adapter didn't fit the shaft, I think the 480 is 4mm. So wondering if I should just snag a Power15 or if anyone has a link for a adapter that would work with a 480 and be long enough. The one I have doesn't get the prop past the cowl. Thanks
