NTM Prop Drive Series 42-58 500kv / 1300w

Hi. I have been reading this forum several times but I havenīt found any reference to this particular motor. I thought it was odd since itīs the same size of the stock one. Does anyone have any experience with this one? I have one in the cart but some info would be really appreciated to make my choice. I would like to use a MasterAirscrew 16x10 with the NTM. Thanks!

I'm using the stock motor on 4S. With the scale prop it pulled 65 amps and the only thing I didn't like was how it felt when I reduced throttle. It felt like it was going to stop due to drag of the 4-bladed prop.

I decided to try an APC-E 18x12 but only had an 18x10 so I went with that. Even though the current dropped to 48 amps, the plane felt so much better. When I finally got the 18x12 prop I felt like it was the sweet spot. About 52 amps according to the wattmeter.

I haven't seen version 1 so I don't know what changes were made. On mine everything seemed fine, but the CG seemed WAY too far back at 110mm and I think 90-95 is right. Control throws were good as recommended, but I did increase the rudder throw after the first few flights.

I don't have any elev mixing with the flaps and it doesn't seem to need it.

I may get some 4" wheels and open the wells up enough to accommodate them. I fly from grass and if the grass is a bit long, the gear doors attached to the legs catch a bit.

My buddy tried one off those on his with the stock prop and it was to much for it but went really well until it burned up. That prop you have may work well with it though

Thanks for that! I just had my maiden flight yesterday and realized that I have a problem getting the wheel aligned with the rudder. I will try your method.

Wow! this plane flies great! I like the stall characteristics. This is the easiest warbird that I have ever landed, but it could be due to size as this is the biggest warbird I have.
I got some footage. First landing was hard, but it got softer with subsequent attempts.

Cockpit!!!?

I want to find this Hobby-Lobby Starmax P-47 cockpit as a spare part. The "seat" in the Hun Hunter from Hobbyking is just downright silly.

Did the EDF stop in time on landing? hehe
The P-47 looks extremely 'floaty'. At all times... take-off... slow passes.... landings...

I need a carpark./runway like that! But even a bit bigger maybe....

Yes, that cockpit should turn up as a 'spare' you can buy eventually!! Very nicely done!
Maybe contact Starmax direct?

yeah Pete, never had an instance where the EDF ran out of runway. It has airbrakes, and they are quite effective. It's by Starmax too. Love it.

You are right, the big P-47 is much easier to fly, take off and land than the smaller Durafly P-51. I didn't notice any pitch change with flaps+gears deployed, and it floats like a butterfly. I was pleasantly surprised by the way it floats.

I didn't attempt a single loop or roll as the batteries were unsecured at the front of the plane.

Nice flying and nice video Miketre Gotta get mine in the air again soon (when it gets warmer). Have only flown funfighters and my Vampire lately and the P-47 seems so nice, big, and slow compared to the funfighters

Here is the video we shot of mine, most of it's kinda high, but you can hear the whine that motor made with the scale prop. When I did the APC-E 18x12 the whine subsided considerably.

Maiden Flight

Well it flew....the tailwheel setup needs a LOT of attention and I think I will squeeze some more rudder throw. A bear on take-off, but I think that is mostly due to the slop in the tailwheel. Used stock motor, prop and a 4S 5000 battery. Plane felt a little tail heavy. Could only get in one flight as the right gear wire is VERY soft and a slight turn when on the ground bent it! My velcro'd bombs were removed before the first flight, but the rockets were epoxied so they stayed.

She likes to pull hard if your fast on the throttle, just have to be ready on the rudder. But make sure the tailwheel is set right also.

Congrats on the flight. That big ol scale prop makes a lot of torque if you're not ready for it, it also makes a lot of drag when you throttle back.

The flaps on mine require almost no elevator mix even when I deeploy them all the way.

Where is your CG set? I'm using two 4S 5000 mah packs in parallel to get it to balance at the 95mm point.

Great photos of your flight.

Greg
