Missing was the Motor, however, the ESC, all servos and Flaps were configured with flap servos pre-installed.

Early this morning, I finally got around to finish the model by installing a brand new Park Zone 15 Brushless motor (950Kv) and I thought to myself, why not make it look as scale as possible so, I found a bag with at least (Quantity 6) Grand Wing Servo (GWS) 4-Blade (10 X 8 X 4) Plastic "Electric" Propellers. I had to hone them to the propeller adapter that I used (Great Planes Propeller Adapter that comes with the GD600 gearbox). Honing out the inner Propeller Hub took patience since you can easily over-heat the Propeller Hub and deform it, if you do not STOP and allow the hub to cool while drilling.

Using a spare Spektrum AR500, and my Spektrum DX7 the model was activated for the first time at the wee hours of early morning around 3:00am Eastern. I was pleasantly surprised on the smooth Propeller power run up using the Black molded 4-Blade GWS Propeller. No vibrations or wobble.

I used Minwax Water Based Polycrylic to protect the paint and decals and it worked like a charm. The maiden was super scale and that GWS 4-Blade provided lots of punch in the thrust department and air speed was pretty impressive as well.

Best of all the landing was spectacular with full flaps (Flaps on Gear switch). Model touched down super slow and like watching the full size! That 4-Blade really helps provide thrust during landing.
Welcome to this thread, Carlos! The P-47D is one of the most perfect RC planes I've ever owned and flown. The E-Flite retracts for this one are bulletproof. I've got hundreds of flights/landings on mine with nary a glitch, and others here can testify to their strength and robustness.

I look forward to your videos, photos, etc. I literally just read through all your blog entries today; cool stuff!

Hey Carlos welcome to the Jug club, long time no hear.....she is a keeper for sure. I rate her above the Spit as the best PZ plane yet.

Look out in July as I am coming over your way and bringing the Spit with me....

Fly safe and have fun

Be careful that setup can pull 40amps and the stock ESC is rated for 30 and the motor 34.

It does look nice though!

A new airframe is only $100 if you give up on that one.

Don't pull on sticks at all if you don't know where the plane is or its orientation (wait until it comes out of the sun before doing anything).

The vibration is definitely coming from the motor on the video, as it goes away when you pull off the throttle. My guess is mount bolts, prop balance, or bearing.

Where did you find a specification on the BL15 motor?

Well I ordered my new graphics from Callie, got the new G25, and will be reaming out the 4 blader for use. Now I just need to sand her down smooth and get her ready for paint. I have all the dings patched just need to get all smoothed out and ready to go.

I used the Power15 specs. They (BL15 and power15) are both 15 sized 950kv motors. I'm sure there are small differences however for a load calculation this is definitely close enough.

Make sure to share some pictures with us. Can't wait to see your finished Jug!

John,

It did more than that! Did not need any trim adjustment what-so-ever and it went exactly where I commanded it to go! Those Flaps are just wonderful and the model slows down very well without any extreme pitch affects such that I did not need to provide any Elevator adjustment after deployment of the flaps! The landing with those flaps made me look like a Pro RC Flyer as it touched on its mains so slow that it did not have a chance to tip over on the propeller!

A few pictures showing the AMP, WATTS and VOLTAGE under load measurements from tonight.

Did I hear you right, when you said it was pulling 36 amps at full throttle? Shouldn't be that bad as it'll unload in the air, right ?

That model's just screamin' for some weathering details and so forth...very nice
