A real 35A esc will put Wildcat a rung up.
There are some poorly rated ones out there. Carefull on that.
Try playing around with the T with the plane in your hand.
Hold it vertical. You can get a feeling for how much T needed for launch.
On a calm day with stock set up I find a healthy 5/8s to 3/4T works.
Unlike some Warbirds our classey F4F does not roll agressivly to the left.
I do not chuck it. Just a smooth follow and let it go.
I do not use much up aditide and naturally tip the wings a little to the right.
I sweated out the first few! Good luck Chris

What is a good esc to put in this bird, what is the most popular one the the f4f? Just might be a good thing going with a brand name esc

Wouldn't hesitate to run an Eflite 30amp, CC Thunderbird 36, Turnigy Plush, Hobbywing, or Sunrise. I'm sure there are plenty of others.

I'm running an Efite 25amp Pro and it works great.

Turnigy D35-36/5 1450kv motor.
I've recently bought an air frame only kits from Al's Hobbies for 37 and have purchased the above power plant http://www.hobbyking.com/hobbyking/s...dProduct=18226
It's weighs 102 grams but I'm not sure how this compares with the stock unit. I've anything from a 40 to 60 amp esc to go with it and my lipos are 45/90c Nano 2200 3 cells. I could also run with 1800 4 cells but lets not ahead of ourselves
Plan to try an 8x4, 8x 6 and 9x 4 APC e style props but I've read conflicting data. One poster stated that an 8x6 on 3 cells pulled 45 amps whereas another obtained a figure of 26amps!
Has anyone got any experience of this motor in the real world?

The problem with the PZ stock ESC is they are only rated for .7 amp BEC. Not much room to spare on servo amperage.

655 watts on 4S? Might rip the motor mount off with that. LOL. Compare an Eflite Power 10 at 122 grams and approx. 450 watts. I'm inclined to think a lower Kv might be a better choice. Prop size: 7.4V/9x6 14.8V/8x4 on that Turnigy, 10-11 inch on the Power 10.

you'd think an 8x6 would be OK at 1450Kv considering they recommend a 8x4 on 4S.

10.5v * 45amps = 472.5 watts.

10.5v * 26amps = 273 watts

The only way to know for sure is install the motor and test different props...

Yeah, and I think this is the source of the perceived RX brown-outs blamed on DSM2. Not the radio's fault, it's the marginal BEC.

I've been installing these UBECs on my 4-5 servo planes, and I use a CC BEC 10a with 6+ micro servos.

Perfect example of how Horizon creates its own problems in this regard. The PZ Stinson is a 4 digital servo plane with a 30amp Pro ESC. That ESC is rated for up to 4 digital servos, so in stock trim, the BEC is maxed out.

Add in the optional flaps? You're up to five and have exceeded the rating of the BEC in the ESC. Not good.

Hey give it a go. I think you will lnow pretty quick if the rateing is honest.
Castle is conservative in their ratings.
Had good luck with the Turnigy plush and k series.
E-flights have been fine.
Have an Esky here that no way can be the 30A it says it is.
I wory about the bec.
With all these digital servoes, I have started using 3A integrated ones.
I see folks using 10A seperate units.
wildcat is not very demanding as is. Have a good time! Chris

So I finally did the power up grade to my wildcat
Eflite power 10, eflite 40 amp esc , 9.5x7.5 prop ,
P-47 prop adaptor and let me tell you it goes like a bat out of hell
I love it.
It pulls 38 amps at WOT and a flight time of 6-7 min on a 1800 nanotech
Great set up

I'm glad to see you're happy with the set-up.....I did the exact same thing.

The only difference is I fly with 2100 mah batteries because that's what I use in almost all of my planes.

Thanks for your thoughts. I think I'll start with an 8 x 4 then an 8x6 and see what my wattmeter tells me. My GWS FW190 flew pretty well on a Turnigy 1700 kv on an 8x4 so I think that the lower kv should work well with an 8x6
GWS FW-190 (4 min 17 sec)

F4F Wildcat - can it soar?

Hi there,
Apologies if this has already been asked - But I have purchased one of these birds with the aim to fly her 'stock', but would also like to buy another and remove the motor and replace it with some weight, and chuck it off a slope.. Anyone tried this?

Many thanks
Dave

Well, I don't know about soaring the F4F but Roger Lombard has sloped soared a GWS FW190, ME262 etc so I guess it would be possible
