Mini-Review

Park Zone P-47 Thunderbolt!


Got this new model about two weeks ago and had to pick it up at Palmetto, Florida which was approximately 160 miles away. I bought it here in the classifieds knowing well that I was going to use this trip to visit my oldest daughter that lives in Tampa, Florida while on the way to pick the model so, it worked in all accounts.

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.

A few pictures of my early morning setup work and at the field.













Here are a few more at the RC Club! Just look at the wind Sock, Dead Calm!!!







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.

Actual Results = VIDEO:

Park Zone P-47 Thunderbolt using GWS 4-Blade 10 X 8 X 4 Propeller with Stock power system 02-06-2013 (1 min 59 sec)



In case you missed what I yelled in that Video

3/4 Throttle: 23.5 Amps / 11.16 Volts / 255 Watts

FULL: 36 Amps / 10.5 Volts / 376 Watts

Ar 500


Be very cautious about that AR 500, Carlos - it could easily cause the loss of your plane. Send it back to Horizon for a free replacement AR 600. I learned this the hard way.

The AR500 is just as dangerous, probably more so, as the 30a ESC in the MM!!! ( and we all know what you think of that item)

This Receiver has flown for countless flights and has endured several crashes. The crashes were attributed to jammed Nose Wheel Steering Push Rod on my T-28 Trojan!!! It overheated the BEC side of the E-Flite 30-AMP and down my model went.

I have flown this AR500 without any issues what-so-ever and since all the discovery of the reason for my T-28 Trojan crashed as explained above it has flown for countless flights without any issues since then.

The Jug does not have nose wheel steering so, it is in the clear, yet, I am paying attention to all control surfaces and including the Steerable Tail Wheel just in case.

Thanks anyway!
Carlos

Just keep an eye on it. 4 of my 6 AR 500's failed. Luckily only causing one crash - the others gave warning signs of impending failure. I'll never use one again.

I believe a couple of years ago, I saw an Alert on the Spektrum Web Site asking customers or potential customers to look for Counterfeit AR500's and I think this one explains....

Of course there might have been QC issues as noted here:

Mine were not counterfeit, bought from Horizon. The Horizon Service Tech acknowledged to me that they had many problems with the AR 500. He encouraged me to return any I had and they would replace them with AR 600's.

Edit: most of mine failed in planes with over 100 flights, a couple with more than 250 flights. Just watch them closely, they usually start to have strange behavior - jittering servos and signal dropouts - before they fail. But one took a plane down with no warning.

do you suggest using the spray? and if so, is there any prep required on the p-47 to spray it on? how many spray cans are suggested to cover the plane?

Fun Fly at MOON PORT MODELERS RC CLUB and my Park Zone P-47D Thunderbolt won 3rd place prize for the Fast and Slow contest!

All this was with the smaller Park Zone 480 (960Kv) Motor and the GWS (Grand Wing Servo) 4-Blade 10 X 8 X 4 propeller setup! Amazing!!

There was someone with a dang 3D light balsa model that won first and 2nd place, next time I will demand category / type restrictions! As far as I am concerned, my JUG won First Place!!
