Happy 4th of July! 4th of July Flag United States RC Plane

Fireworks Beers Beer Cheers


Just got home from a cousin's house who lives about a mile away. Watched her neighbors do a bunch of (illegal) fireworks over the lake, and the city's fireworks were also visible in the distance.

Happy 4th (now 5th). I have a Magnum .25 R/C, resembles an OS .25 SR. I heard they make good replacements for the old .35's in C/L stunt planes with R/C carb replaced with a venturi. Smile

Hi Mark,
Independence Day is like a birthday... Happy Birthday ! United States
I mentioned in a previous post that I had some r/c carbs to convert your C/L LA.25.
Found the forgotten FX while looking. I remember flying my buddy's Sportster, great plane, great times... Very Happy
(I have two still great running FXs, plus two MagXLSs that are arguably even better Smile )
I know you will have fun. That is the important part. Cool

Nice run 1/2A nut, 8-8? We used 9-4s to keep speed turning in the rc combat box. Max speed radar'd was 93mph out of a downwind dive with ~1/12th scale combat planes. No pipes, just drilled out/cut off the muffler exit tube. 15% Nitro fuel. Having the sound of 5-10 in the air, all running at peak was awesome ! Cool And trying to bring your streamer back !
GG,
The Magnums are just copies of O.S.s.
GP=FP, Pro=SR, XLS=FX. (the early MagXL was a dud, you want a later XLS)
I've burned out allot of the pre FX .25s trying to mod/keep up with them. Fun times. Very Happy
The FX.25 is a great engine. (theMagXLS has allen vs phillips screws, even performance )

I like how this forum can change from the topic. I Love This Forum!

I remember the model mag, that had the introduction of S.M.A.L.L. (Randy Randolf?)
At the time, we were burning jugs of fuel through .40s.
Doubled our flying fun. Never looked back,
Take care,
Have fun,
Dave

I've got the plain bearing crank ones, the .15 is a little powerhouse, probably could power a Ringmaster S1 no sweat (ditto with my OS .15FP-S).

We usually return also.

Randy was the designer of Bee-tween, low wing reedie powered 2 channel sportster and others.

Back in the early 1980's while working at Douglas Aircraft, I contacted a couple R/C clubs nearby about joining. They told me flat out I could only join if I flew 4-channel .40 or larger powered aircraft, NO SINGLE OR 2-CHANNEL, NO HALF-A.

Being a reservist,  Memorial Day  I'd leave the area on extended weekends and fly at military bases. NO FLYING in local municipal parks. Sad (Kommunist Kalipornia, made sure the door didn't hit me in the  Reading on the way out). Doh!

OTOH, visiting my parents living then in Arkansas, the RC club in North Little Rock had a different spirit. Very Happy All R/C welcome, including half-A, @Kim 's country. Very Happy

Hi gg,
The Mag.15XLS was the best in SSC. (slow survivable combat) Not flown here.
Same GP=OS for the .15s...
I think piston/cyl/cranks are interchangable, not tried it though.

We had to wait, till the .60 pattern planes did their routines... Refuel.
Then could 'not bother them'...
With our Cox.049s...
Take care,
Have fun,
Dave

Back in 1965 as an 11 YO, rode my bike one weekend to the inactive taxiway at Kessler Air Base in Biloxi, Mississippi. (We lived in a neighborhood just outside the main gate.)

There, the military would fly their R/C planes. I watched a Goldberg Shoestring Racer in yellow with red trim, very professionally finished, after starting, taxi into takeoff position, brake, then take off, do a bunch of stunts, land, taxi to the parking area, brake, then engine shut off.

Before then, I never witnessed a model airplane fly like a real one. It was about then I had just finished my Scientific Musciano designed 18 inch F6F Hellcat with Cox .020 Pee Wee C/L, wing silkspan covered, I painted in dark blue Pactra dope.
