That puts me down there with the masses. No warbirds and only a very few four cycles

NO not a nickel [X(] but yes that is still in the power band. Now is it the best? That is another question all together different.
Is there a complicated APC?

I used the O.S. fs-20's for years in an old House of Balsa .20 size Texan.
I always used the Master-Airscrew 9x6 with painted tips.Worked great.I will again be using
two fs-20'son my Royal B-17 for the outboard engines, with fs-26's for the inboard engines.
My fs-20's both have a tonof time on them, but still run great! (I've had to replace the
bearings a few times, no big deal)

Please link us to the thread on that B-17. That is holy.

My hobby time is too valuable to be spent on puppy love.[sm=wink_smile.gif] I give and demand a lot from my loves.

That's how I used to feel about street racing.
"Give them no quarter!"
Then I stopped competing and began trying to enjoy myself, while earning a living. I never did manage to accomplish either. Funny thing. Now I realize that all that really mattered was loved ones, family, friends and just surviving. Now here I are - an old man. And as my late father-in-law discovered, you can't take it with you. Thanks, Pops!

I have lots of electrics: starters, glow drivers, plugs, servos...

Throw away?! Nah!
However, I am selling my larger two and four-strokes and I'm falling back to electrics. But mostly RTF electrics at this point and some ARFs too. Not because I prefer electric over IC, but because of limited physical ability and the fact that my reacquired pit crew (absent for over twenty years, while working at her career) refuses to deal with large displacement glow engines, regardless of the number of strokes. I can still manage to get the EI equipped gassers running, if I can get her to haul them from the car for me.
I do love electrics for one reason, though. That reason is that you do not have to worry about fuel proofing the model, as long as you keep it from the exhaust blast of another glow powered model.
Just think, buy some 1.5mm laminating film. Scuff it a bit before putting it on the model, if you choose to paint it. Easily apply to the model with low heat. Tape off the model appropriately and then spray paint using cheap department store spray paint. I will assume that you have already checked the compatibility between your chosen laminating film and your spray paint. Spray paint for plastic should be ideal for this usage. Voila! No expensive glow fuel proof coverings or paints wered needed or purchased. Think of all of the extra cans of spray paint that you will be able to buy because of the lower price of this type of paint!

I have to agree with most of that, other than the just surviving and giving them no quarter. Sportsmanship and ethical behavior are very important. Also one should strive to live life to the fullest. We only get one chance at it.
Now competing within the strict definition of a set of rule laid down by a governing body. Now that is fun, challenging, responsible and above board.
All the best,
Konrad

And the road is full of bodies. The track is the proper place for this stuff. (I speak as a first responder)
I built a lot of SCCA cars to the rules, H production and GT 3 through 1 . Again as a driver I sucked, but the machines often won titles in the hands of those that could drive. Without rules there is no fun. Discipline and dedication are key to any success.
OK, talent does come into the picture.

The key to stetting up a ship is matching the prop to the power curve and to the airframe drag curve (wing loading has a lot to do with this).

Stall speeds are getting off topic as you were talking about the best performance on a FS-20.

This is what I was asking about; how do you prop a plane to airframe drag? I also asked you what type of drag were you talking about.

This applies to electrics as well as the OS FS-20 four cycle engine. And to any "type" of drag that applies to the airframe, induced, parasitic, etc.
Stall speed is very important! As this is the bases to set the cruise speed. I recommend 2.5 to 3 times the stall speed. Now the power needed to drag something through the air goes up by the cube of the speed. So again speed is paramount to determining the power needed. Or the reverse with a limited power source one can only go so fast. The key to this is how hard the wing is working (the coefficient of lift). Yes, there is more to this like frontal area wetted area , etc. But in the end it really is the wing.
Now we do use wind tunnels or stop watches (out on the field) to find the best set up. Truth be told it is the flight test that verifies and validates the set up.

The competition spirit is also the catalyst of innovation.

I'd like to take issue with your "also". This implies that you agree with it being the "root of all evil". I hope that isn't true.

Racing without officially sanctioned rules is real racing. Everything else is a wallet race. As soon as the racing is reduced to an event, the fun disappears because only a favorite few will be permitted to buy the best/fastest parts for their steeds.
I should clarify that I was drag racing automobiles, I suppose. But that was back when shifting a manual transmission well could really determine who won the race instead of like today. Our old saying was, "Slip and slide with Power Glide". It's disgusting.
R/C flying is at its best when just a few fellows that really enjoy each others company get together to go flying. The next best thing is an obscure club that can barely keep the field mowed. When it gets bigger than that, you generally won't see me there.
