Thumbs down Junk eMail?

Today I received an email with the RC-Universe logo, advertising dog food. What does that have to do with our hobby? If this is legit, I hope you're getting paid well. If not, somebody is using your...

Thanks for your kind offer, Steve. I have one set of Green & White, with the Goldberg ball chain! Just hanging in my shop for nostalgia trips! I never knew about the color-coded flags for 53 MHz. ...

Thanks, Steve! I fly on 50 MHz, the HAM band, and I have two black flags. Almost everyone in my club is on 2.4 GHz now.
How times have changed since the days when I flew Green & White.

Thanks for the info, Pete! I should have looked there. Found nothing on Tower Hobbies, and my local hobby-shop guy said, "What century are you from?"

Sorry I'm a Futaba flyer. I have a T14MZ...

Frequency Flags?

Does anyone know who supplies frequency flags (red for 72 MHz, black for 50 MHz, etc.)?

...and especially the little plastic thingies that attach the flag to your antenna?

O.k., I know most...

RE: Converting Glow to Ignition???

John; I feel your grief for allowing a fine engine like that to get away from you. One of my favorite engines is a Fox .40 that Duke Fox gave to my son, sometime in the early '80s when the MAC Show...

RE: Converting Glow to Ignition???

Exporter; Thanks for reminding me of this thread, which I enjoyed reading again, also.

I believe the tygon (clear plastic tubing) was attached to the carburetor intake, to damp any turbulence...

PILOT FIGURE WW1 GERMAN

Does anyone know who makes (or made) the WW! German pilot figure who wore a Prussian helmet with a spike sticking out the top?

The one online from "Iron Pilots" is a bit too small. I need one...

RE: Converting Glow to Ignition???

You got that right! We tuned for full throttle and never backed off. The airplane was designed to average 50 mph at full throttle. We also tried using smaller carbs in our tests of 2-stroke glow...

RE: Converting Glow to Ignition???

Actually, it was 1947. My summer job in high-school was 1/2 of "the apron crew" at Marion Airport (Marion, IN). Two of us drove a Crosley-powered gas truck, with which we fueled visiting aircraft,...

RE: Converting Glow to Ignition???

Hi Aeronut; Since gasoline produces more heat than alcohol, you need a larger percentage of oil for converted glow engines than for engines designed to run on gasoline, such as the weed-wacker...

Thanks for the link, W8YE. Back in the early '90s I assisted Jim Kelley in running a Saito 52 on gasoline, with which our team won the first and third running of the California R/C Marathon.

RE: why does my stick roll with just rudder?

Aerodynamics 101: When a fixed-wing aircraft yaws, the wing on the inside of the turn slows, relative to the wing on the outside of the turn. This is the primary reason for yaw-induced roll. ...

RE: Converting Glow to Ignition???

Hi Gord; Most of the push mowers I've seen have two-stroke engines, similar to leaf-blowers and week-wackers. Are the four-strokes you're referring to light enough for (large) model airplane use?

RE: Converting Glow to Ignition???

Thanks for the photos, John. That is certainly a novel arrangement. I suspect there must be another spring to hold the points open, until it's overcome by the cam and coil spring. Is that a leaf...

RE: Converting Glow to Ignition???

Typically, the ignition system for four-stroke engines is driven by a cam or gear on the camshaft, since that turns at 1/2 crankshaft speed. In this way, the valves and spark are timed to occur...

On your '43 Chevy you have a cam with six points, which opens the breaker points six times during two revolutions of the crankshaft. (The camshaft, which drives the distributor, rotates at 1/2 speed...

Yes, there were diesels. Two teams from my club ran diesels, but they quit when the engine cooled down. The course was an "L" shape, so you had some upwind legs where the engine had to work harder,...
