TD 010 Re: ***The World's Smallest Traveling Engine*** SIGN UP!

There is an application called RPM Gauge for audio taching by android phones. I ran your vid on my phone on a split screen with RPM on the other half of the screen, measuring the engine speed by the sound it emits. I made a screenshot on the split screen and that was it.

Oh, okay! I'll see if I can find it and give it a try.

Laughing Laughing  Yeah, you're probably right!!  But man, it was fun!  I still haven't figured out what we were doing wrong with the tether  Huh...  Huh...   I tried just spinning it around me without the engine running, gradually letting out more and more line to the 15 foot limit and it seemed to be balanced just right.  The spin test can be seen here: https://youtu.be/44Em1XJpM7c.  However, under power it just didn't get off the ground as I've watched in other tethered flights on You Tube.

In my heart, I would have loved to try it on the free flight but I just didn't want to have to climb no tall pines so that would have to wait for a nice calm morning.  And it was just too windy to try it on control lines even the 20 footers.  Heck, if the "big boys won't risk their 35's and 40's, I'm sure not going to risk an engine that doesn't belong to me Doh! !! Laughing Laughing   Nevertheless I am so grateful for the opportunity  Clapping  Clapping

TD 010 tether flying

Post  jmendoza Mon Sep 20, 2021 10:14 pm

My dad gave me a Cox TD .010 for Xmas 1969. I wore it out flying tether, put several quarts of fuel through it. I rebuilt it with a new cylinder and flew it for years on an Ace Guppy with pulse ruddder only.

Rule #1, No wind for tether flying. You have no elevator so the plane will climb going upwind and dive going down wind. If there is any appreciable wind, it will climb too much and then dive into the ground on the downwind.

The Delta you have just need more speed to get stable and airborne, so try something that does not need to fly so fast for starters.

The Guillows 500 series WW2 kits are made for rubber, or tether flying with a TD -010.

Build a small sheet balsa plane with about a 10 to 14 inch span wing 2 inch chord max, and a conventional tail with a generous rudder set to turn outwards. No incidence, no dihedral. Tether attaches to the leading edge at the tip. C/G should be 1/4" aft of leading edge. Attach the line to a 3 foot long 3/8" diameter hardwood dowel so you can whip the plane. Use Spectra line, the lightest test you can buy at the sporting goods store. Put a dime on the underside of the outboard wing tip.

Have your helped launch the plane over grass and be prepared to walk quickly to your left and take a few steps back to get line tension. Pick a calm day, morning is best.
