Bartricky, I am with you on this one. I absolutely love to fly my SS around, and juuuust graze the tall weeds, or do touch and go's. And, of course, I get into trouble, and jump on it to get out! To me, it is a balance act, to have a very good amount of power, butstill try and keep it light as possible. My new foamie, a HK AT-6, seems like it just doesn't like to slow down, even though it is stock, and has a lighter battery on board, so I just have to live with that one. Flies well, just fast.-------Metalguy

Me too. I've never got into problems with too much power but have from too little. I like to know there is power under the hood when I want it. If I don't, I don't get heavy on the left stick. I build and fly the way I want and others can do their thing. I'm just not the kind to stick to the plans but want some of my engineering in the plane. For example, I installed a brushless motor in my UM PZ Corsair and series 1s batteries(7.4v). Very exciting micro airplane, now.

I understand what everyone is saying here. I am getting 200 watts, at 19 amps and a speed of right around 60mph. The great thing is I do not need all of it. My 5 minute flight times are coming from a lot of high speed passes and maneuvers. I could probably squeeze 8 min out of her if I wanted.

I just love it cruising at about 1/4 stick and having great fun! She also slows down to a crawl on landings!

Happy Flying!

I'm a firm believer in building a plane light so you get the best possible efficiency to weight ratio, but hey, i'm with you guys! Who doesn't like to go WOT and scream through the skies!

Especially with a warbird!

Fly scale. Then fold the wings on the way down. We did that 1 time with a Harbor Fright C M P Piper Cub. Waited too long to pull up. THUDD

Needed a penknife to dig out the motor.

Great day to fly today - one of the few we have had lately with winds under 5 mph and temps in the 70's - but I had too much work to do to get out - bummer.

Am now thinking I might just toss the power 25 on my Mosa 2 that is coming out of my big P-40 and use a 12x6 prop and a 3300 3s. I need the weight up front to help with the COG - guess I don't have to run the motor all that hard anyway - she should cruise at a pretty low throttle setting with that set up. Might as well replace the lead weights with more motor.

Any opinions out there?

Hi Wolfe,

It's a better setup than the 480 size one.
Is the AUW the same as the 480 one + ballast lead ?
I was told long ago that GWS prop HD1260 works better than other brands' ones. I'd guess that yours is the APC one.

The Power 25 weighs 68 grams more than the 480, Will take off 103 grams of lead weight that was on the motor mount behind the motor. So net loss of weight is 35 grams that sat further back than the motor - should be close enough.

The 3300 3s weighs 103 grams more than the 2200 3s I was using - if I change batt size. That sits pretty much on the COG line - perhaps slightly forward - so that should not affect COG much

Don't have an AUW on the entire set up yet - will post it when I get it

Wolfe,

My Turnigy 3S 2200 20 Lipo weighs 185 grams, your 3S 2200 seems lighter than mine, but it's amazed to know that your 3300 3S is lighter than my Turnigy 3S 2200 20C by 82 grams.
Let me know of its discharge rating, I am afraid that yours might be with lower rates.

OK I made it clear. Tks
Your new set up will bring you far more than enough thrust on Formosa II.

I am anxious to try the new set up - should get it done this weekend and get her in the air if weather permits.

Wolfe,

It's something like a maiden on this bird. I'm sure you know that it'll be crazy or vertical unlimitedly when giving WOT.

Yeah - she will be overpowered, if anything. Will probably feel like a different plane. I would expect unlimited vertical.

I can always go back down to a Power 15 if it ends up too much power

But I had a lot of dead weight with the lead sinkers for balance - might as well turn that into "productive weight" and see what happens.

too much power.....How will you know (he-he).

Never said any of mine have "too much power." A couple don't, however, and I enjoy scale flight with them. With my GWS warbirds, however, I enjoy the thrill of coming out of a steep left turn dive and giving it full throttle into a fast level pass then stand it on it's tail rolling vertical.
