Official Nexa 1570mm (61.8") P-40 Warhawk

Chalredline1 - the maiden went well in the sense she flew, but I needed to do more fine-tuning. I flew her about 4 times the other day and after the first 2 flights she was just pretty pitch sensitive, so at the field, I adjust the control rods on the horns, lowered my rates, and while it made it a little better, it still was pretty pitchy. So I took her home and realized that where I had initially installed the elevator servo that it was just too far away from the elevator rod. So I moved the servo in and put the rod on the innermost hole of the servo arm. I hope now the resolution will be much better and it should eliminate the pitch sensitivity.

You can see the maiden here in Friday's live show:

How did the maiden go? I'm building this now and going electric. Seems like you had to adjust the motor quite a bit above the guide lines that were printed on the mount to center the motor in the cowl.
Thanks

Looks good James! Good luck with the maiden.

That looks great James. Thank you for sharing. I have yet to order my plane. Will be something to do since I need to wait for the Iowa winter to get over with.

Hey cruiser, I finished her up, just waiting for a battery strap to come in to secure the LiPo and it's maiden time.



So with the 6000mAh 6s Admiral Pro 50c LiPo battery, she totals 9lbs 10oz.



I didn't realize she came with a 3 blade spinner, so i ended up grabbing a master airscrew 15x7 prop (painted the tips and balanced). Based on the Admiral motor shaft length, with this prop I had to use a spade bit to just take off a bit of the hub width to get the prop nut on with a washer. And the width of each blade was larger than the spinner blade grooves, so had to dremel those open a bit. But all good.



Putting the Watt meter on it, I am got a max amp draw of 63+ on the table, but it was 55amp steady for 1 minute. So should only decrease in the air. the total watt power was 1536.2



The battery compartment fit a 6000mAh perfectly, easy in and out and she CG's perfectly at the book 4" - 4 1/8" CG location. No extra weight needed.



So overall I am happy, but I'd be happier if the weather looked good for a maiden this week. Maybe have to be next week. But we will have videos coming of build assembly and flying when that happens as soon as we can.

James, I'm glad you are working on this bird. I have the same interest to use 5000-6000 batteries. How is the fit and CG working out?

[James]

Hey guys, wanted to get this thread started as I am in the process of assembling this P-40 and so far I really like the ARF Kit.

This is my first Nexa WW2 Warbird and I am very pleased with the overall fit and finish of the model thus far. I am following the instruction to the T and haven't run into anything yet that I think should be changed.

As far as electronics and components I am setting this up electric using the exact recommended specs on the webpage which are:

REQUIRES:

• Admiral GP10 5030-400kV Brushless Motor
• ZTW Mantis 65A ESC with 5A SBEC
• 6x Hitec HS-485HB Deluxe Ball Bearing Karbonite Gear Standard Servo Airplane Multi-Pack (6 Servos)
• 3 Blade Propeller (14x8 or 15x7)

The HS-485's just drop right in. No cutting or manipulating the servo slots are needed. Also, the Mantis ESC has the same size bullets as the Admiral GP10 so it's nice to not need to solder any bullets. I intend to fly this one with a 6000mAh 6S pack.



I unboxed it Monday and got the wings fully completed and the tail assembly together in about 5 hours (with filming pauses), then today I got the elevator and rudder servos installed and the motor mounted to the point where it clears the cowl. Tomorrow, I should be able to finish it all up. Just need to attach the ESC, mount the cowl, install the battery tray and put the decals on. Then set up the RX and I will then start figuring out the CG. I assume I will need nose weight, but we will see how much tomorrow. Then hopefully I can maiden her on Thursday and show a lot of the assembly and flying footage on Friday's youtube live show.

I am excited. She is just about the size of the FlightLine Spitfire and Corsair and will fit right in. But after I get pictures and video, I think I will be painting this one and calling Callie, but we shall see.

Nexa P-40 Warhawk 1570mm (61.8") Wingspan - ARF

The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. It was the third most-produced American fighter of World War II, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facilities at Buffalo, New York.

The Nexa P-40 Warhawk is a .60 size electric or gas option scale series warbird with a 1570mm wingspan, constructed primarily from balsa wood and covered with a fuel-resistant covering. This ARF requires assembly and installation of your choice of servos and power system, and includes split flaps, center drop tank, painted pilot, machine gun, antenna and other scale details. The large battery hatch affords ample room for either electric or gas setups. To complete the scale appeal of this beautiful P-40, the model includes electric retracts and scale struts. Impress at your flying field with this iconic stunner!
