Hello Sportflyers!!

I have been hanging out on the 1/2a forum for some years now but finally pulled my Midwest Aerosport .20 from the ceiling and got her ready to fly. I built it 6 years ago, it had a brand new OS .25f that came with the kit from a hobby shop around here for $70 (kit and plane)!! After spending about 2 days breaking in the motor before flying (yes I finally learned the hard way to do all the things recomended before flying and things seem to work out better) replacing the batteries, readjusting all control linkages, servos, etc.... A little nervous but all worked out well. As usual the wind picked up to 15 gusting 23 mph by the time I was ready to fly! I flew anyways and it handled the wind well. The plane tracked well, looped, rolled, snaped and spun well! Also slowed down to a crawl in this wind and landed great!

I must say, having an OS engine that starts first flip (no electric starter) good to go on the last needle setting, transitions from idle to full power and back without a stumble was very nice. Reminds me of all the .40 size planes I flew in the past!

I will always keep a few 1/2a planes around but I gotta say, these bigger planes and engines sure are convenient!! There is also a .20 Super Sportster with an Enya .35 4 stroke,done and never flown hanging on my basement workshop ceiling. That will be next. I will try to attach a pic of the Aersport in a few days, ithas some green on it from the tall grass.

this was probably the last warm,70degrees day here in Southern Ohio, great way to end the summer. Oh and by the way, I love building Midwest kits!

My favorite plane size is .25, although I've been known to put .32 and .36 engines in them. IMO they provide a good balance between size, flying characteristics, portability, and price. I've heard many comments about how smooth and fast some of my .25 planes are see a good amount of surprise when they learn it's a .25. My beater plane is a WM Aircombat Zero that's got an OS .32 FSR. I've flown the heck out of it and it just keeps going.

Is your .25F the regular version or ABC? Either way, it's a great engine. For long life, remember to keep it on the rich side of peak, always run out the fuel at the end of the day and give it a bit of afterrun lube. I prefer fuels that have some castor.

Very cool. I scored an AeroSport 20 kit in great shape at the swaps last year. I plan to build it this winter
and it will likely get a Norvel .25.
I too like the .25 size class for the same reasons: Good performance, low cost, and convenient size. I have
a CG Eaglet with an FP .25.

It is the ABC version. Runs great and I am using Castor (per instructions) since I had a gallon of Sig 10% nitro, 20% castor, I added about 3 ounces castor. I forget my chemistry but think I got it right. Instructions say 23% castor oil 10% to 15% nitro.

To bad Midwest doesn't still make some of their kits , there are a few that would be good for the new builders and some electrics . I have an Aero Star 20 that I've been thinking of converting to electric . My Electric Hots was one of the neatest before it's demise. By the way I'm into fuel, electrics are just starting to interest me a little. Mostly gliders and slow combat. ENJOY !!! RED

Here is an Aero-Star on Ebay for anyone wanting one. http://www.ebay.com/itm/MIDWEST-AREO...item45ff4d119c

Also if you like .25 sized planes check out Bluejay models (bridi planes on google) and have a look at the 25 sized aircruiser. I built one with the stretch wing recommended for electric conversions. I just use an FP 25 bought NIB off Ebay.

What a simple configuration.
Of all the designs, it ought to be a piece of cake to scratch build.

Well it is 55 degrees out and blowing 20 to 30 here in southern Ohio. No flying today!! Decided to post of pic of the Aerosport 20. I had an Aerosport 40 years ago that I sold, wish I hadn't, flew as solid as this one but a little bigger. I probably had over 200 flight on the 40. A little heavy but very tough and durable. Need to keep your enregy up on these to do aerobatics, lots of fun to fly.

Midwest designs were great! Amazing how many of these great designs have been lost. I missed the Aerosport series, but I flew the Little Stick, Sweet Stick and Super Sweet Stick. Plus I think the Aerostar .40 might have been the best trainer ever.

Also that OS 25 FABC is a jewel. I still have mine from the 80's.

I flew with .049s way longer than anyone in my club, but not anymore. I like engines in this size too, but if you like 'em small, I have to say that any good .09 - .19 is just as easy to start and runs really well too.

But I do have a .25 FSR, and I agree it is a very nice engine, but it does better on a bigger muffler. The TT .36 muffler gave me a few hundred more rpm. No adapter necessary...bolt pattern is identical.

Jim you're right about the OS 25 fsr liking a bigger muffler. I found a TT.25( old model) muffler that bolted right on and gave me 900 rpm. Never had much use for the stock one after I found that one.

I like these size planes also. I have a 25la in a Sig EP20 turning a 9x5 prop. The kit was designed for either electric or glow. I love it. That inexpensive and cute little motor is so easy to use and reliable. The Sig 4 star line speaks for itself, I believe the 20 version to be no exception. Builds a little nose heavy with the glow option, but is designed for a fuel tank hatch. It is so easy to toss this machine into the car and go. Here is a couple photos of a 4star40 and a 4star20 together for size comparison purposes.
