Maidened my Petie 2nd tonight, what a nice flying plane. I think it needed one click of aileron and she was tracking dead straight. I have a park 480 on a MAS 10x7 and it's pretty quick, not blistering fast, but just about right for me. After dinner I'm gonna go put another couple packs through her.

Matt...are you referring to an E-Flite Park 480 1020KV? Just curious because I have one laying around and am thinking of starting with that when my Stang gets here. Will probably use a MAS 10x7 as well. This is my set up on my E-Flite P-47 and it's just about perfect.
Also, if it is the E-Flite 480 how are you mounting it? With a whole different mount or just some sort of adaptor onto the Stang's mount? Thanks

There's actually two park 480's, the 1020KV one that you have, and I have the 910KV one. I had to buy a motor mount off of ebay to mount it, cost $20 shipped.

If you power up the two motors without a prop with an 11.1volt battery...

then the 910KV motor will spin to 910 x 11.1 = 10101RPM

The 1020KV motor will spin to 1020 x 11.1 = 11322RPM

So if you put the same propeller on, then the 1020KV would produce more thrust, but consume much more power.

Itís not quite a perfect equation but its close.... KV x Volts = RPM (unloaded)

According to advertising, the brushless Park 480 910kv does 250watts and the 480 1020kv does 275watts. The brushless 480 they put in the PZ Trojan, Corsair and P51 Gunslinger is a 960kv and is apparently somewhere in between. (They probably do stuff like that so guys spend more to do a conversion .)

My flat wing aileron HZSC has the Park 480 1020kv (Rocket Cub) and seems to do stronger vertical than my stock PZ Corsair. Looks like wing and tail drag would be similar, but Corsair nose and fuse is a lot wider. I have another SC for training with smaller Park 450 890kv and it still does pretty strong vertical. Of course it also depends on what prop you do.

If you have a 480 1080kv laying around getting lonesome, it's probably worth the tinkering to put it on the more streamlined P51 gunslinger. Of course, you could get a power 10 or equivalent .

And also the brushed 480 inrunner plus gearbox they put in the stock HZSC (and older PZ P51, Focke 190 and Spitfire) does about 60 watts and with a 3 lipo does about 90 watts.

Gotta add my instructor buddy (40yrs RC and now doing exclusively electrics) has some advice. He says stock power is okay, more power is better, and way too much power is just right. However, he loves he new stock P51 Gunslinger Icky

Thanks Matt. If you don't mind me asking, which mount? I'm aware of the aluminum ones that this guy makes for the Corsair (and I think Trojan) as well as the Super Cub but never knew there was one that would work for this particular ParkZone P-51. Do you have a link? Thanks

I'm going to put a 12X6 prop on it and try it out on the stock motor with the 30A esc,

Wish me luck.

here ya go Olias-

http://cgi.ebay.com/Parkzone-T-28-Co...d=p3286.c0.m14

works pretty good, still uses stock motor mount, if your using the stock spinner you can use the spacers it comes with... i put on a great planes spinner, so i had to push my motor back and use 1/8th inch spacers instead of what the mount comes with.

I would say 4s is a little too much for that motor unless you plan on running 8" and lower props, 4S and a APC 9x6E will draw 48A and the motor is only rated for 46A download the scorp calc and or check out their prop charts
