This way aileron will function with no hindrance from deployed flap and perhaps aileron will still function aerodynamically with flaps extended. Your thoughts…

Cowl flaps would not work when the aileron is the size of the wing. You would have to decrease aileron to 50% of wing and then the other 50% can be cowl flap or normal flap. Way easier to just follow the other posters DIY.

I am thinking of upgrading my motor. But I don't have the money to go brushless right now. I have one of these motors from BSD laying around, does anyone know if it is better than the stock motor on the P-51?

I also have this prop for it.

I have to sort out the binding AS2000 but I should be able to fly it in the next two weeks.

The Gravity Zero Would be cool to be bashed into a Val or a Kate (make a longer/lower Cockpit and add wheelpants) for near scale Dogfights with the UM P-51.

The AR6400 brick runs the Elevator and Rudder and a Single 3 - 4g servo can work for ailerons (though I used the dual AS2000 setup). Power is a 5g 2K Kv Brushless with a lightened 10A ESC. AUW is 3.8 Oz which is about 2 Oz less than stock Cox Warbird.

The best part is the painted Kit with everything in the picture (less the prop and motor shown - it comes with a brushed motor/prop) is $14+shipping from the US. I bought 3 for $50 shipped and they should be arriving today via UPS.

What about flying qualities of these kits?

See Modfly's Cox Warbird Thread

The bottom line is they appear to fly great at 4 Oz and AUW's as low as 3.5 Oz is completely possible with an AR6400.

Their only drawback vs. a 1 Oz plane is you can't crash them without any damage, so attempting stunts you can pull off with a UM P-51 may not be adviseable.

Is there a chord that could allow the new E-flite 250s to be charged with the celectra 4 port charger since it cannot fit into those narrow slots? I thought I saw it earlier in this thread or another, can't seem to find it. Thanks in advance.

Look up RCBABBEL here on the forums he makes them, he also sells the 240mah lipos.

Thanks Tube

As I just started flying the Micro Mustang in temps around 40 degrees with the 130mah battery seemed ok and I was able to fly for 7 minutes or so....besides the longer flight time of the 240mah will I see a power increase also ??

Yes you should. Calculate the C rating with the mah to get current output.

If you guys are looking for some better batteries than the usual suspects, please have a look at these.

http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=280440832505

180mAh, 15C, 4.8gram. 38mm x 12mm x 8mm. They fit the standard Parkzone charger.

On test these perform very similar to the popular 6 gram 240mAh 20C cells from a popular supplier. The 180mAh 15C cells actually gave a higher voltage under a 1amp load, with very slightly less duration.

Are you the seller?

Yes i am.

Totally new venture.

I've been modelling for over 20 years and fell in love with the new micros as soon as Kyosho released the Cessna.

I was trying to buy some decent batteries for my Sukhoi soon after i got it and tried the usual cells and found them lacking. So i set to trying to source my own. I worked with a large manufacturer and these are a purpose made cell. I worked with their lab and we tried a few different cells. These cells and Miniaviation are the result.

It would seem to me that you have discovered the Holy Grail to lipo batteries.
You have better performance than a battery with 25% more C and 20 % more capacity.
The only question I have is how much are they in US dollars and how much shipping to US, in US dollars?
Thanks
