One of my fondest memories is going to contests up in Ohio, Michigan and Indiana with Don Lowe in his old Pontiac station wagon, which had the aroma of castor oil, that came from the fuel that had dripped on and seeped into the carpet in the back.<br>

I'm afraid I must take issue with two of your statements:<br>
1) I'm not afraid of electric, I just don't like it. Part of what I like about the hobby is the engines, I love the smell of burning nitro in the morning, smells like victory<br>
2) There's no such thing as too many YS engines to those who like them<br>

It is an interesting question for sure...<br>
Can you think of any other form of aviation where empty weight is more important that Gross or take off weight?<br>
Of course one cannot blame the IC fans for being afraid of electric technology.<br>
<br>
Personally, the bad news is that the new knee joints I had installed last year are not permitting me to squat or kneel. It is tough to deal with tending an IC powered airplane with that limitation.<br>
The good news is that electrics do not appear to require the operator to squat/kneel.<br>
<br>
Unfortunately there remains the problem of recovering the investment of too many YS engines and the accompanying airplanes...<br>

I beg to differ. The rules are already slanted to favor IC: the way the airplanes are weighed. IC airplanes are weighed without fuel; electric airplanes are weighed with fuel (batteries) and both may no more than 5 kilograms. OMG, here we go again!<br>

I've been at this longer than most and have known from the beginning that the propulsion system is the key to winning in Pattern competition. It can also be the most frustrating due to constantly changing conditions. I found that the gas engines with spark ignition were a lot more consistent than glow and that reduced the frustration. I have more recently convinced myself that electric is the least frustrating. A few folks have gone back to glow after playing with electric to get more power for windy conditions. We are now getting close to getting more than enough out of electric systems (3 to 4 HP?) and when that happens we won't have these discussions anymore. However, before that happens, the rules will probably be changed to favor IC.<br>

I've been lurking for a long time and after reading all the things that one needs to do to successfully fly electric, it makes one wonder how things would be if electrics were the norm from the beginning of powered R/C models. It might go like this;<br>
<br>
Hey guys, I just bought this little IC engine and I tried it on one of my Pattern models and it works really well. "Look what it will do;<br>
1. It has just as much power as our electric motors.<br>
2. The only batteries you need are for the flight pack, glow igniter and the electric starter if you don't like to flip by hand.<br>
3. All you have to do is pump fuel into the tank, spin the engine with the starter and fly.The tail gets a little oily, but what the heck, it's fairly easy to clean up.(Switching the radio on first is a given.)<br>
4. You don't have to haul a generator or an extra car battery around to charge motor batteries."<br>
<br>
Please don't take this the wrong way. It is tongue in cheek and just an observation. I also have too much time on my hands these days.<br>

A 100 ohm resistor may be enough to charge the caps and make the ESC<br>
"active". Bad idea...<br>

Good. I will try it. What wattage 100 ohm resistor? Let's see,<br>
doesn't sustained power equal voltage squared, divided by the<br>
resistance? If so, 42 squared, divided by 100 is 17.64 watts.<br>
That's probably overkill, since the current surge is transitory. How<br>
about a 100 ohm, 10 watt resistor?<br>
<br>
Just thought of something: With the 100 ohm resistor across the<br>
arming plug receptacle, won't the ESC be on whenever the batteries<br>
are plugged into the circuit?<br>
<br>
BTW, what about Castle Creation's statement that the "spark is your<br>
friend'?<br>

Put a 100 ohm resistor across the arming plug receptacle. Then the<br>
capacitors in the ESC will charge without a spark as you connect<br>
the batteries. When you connect the arming plug, no spark.<br>

I have a problem which I am sure many other E-powered airplane<br>
owners have that I'd like to solve. I use an arming plug to<br>
connect the two 5S Lipo packs to the ESC. On initial contact of<br>
the arming plug with the receptacle, there's a big spark thrown.<br>
Eventually the contacts on the arming plug and receptacle get<br>
burned to the point where the electrical contact is very bad.<br>
Yesterday I had to land my airplane deadstick because (I think)<br>
the ESC saw what it thought was low voltage out of the battery<br>
that was actually due to the burned arming plug/receptacle<br>
contacts. BTW, I am using high-amp Anderson Power Pole<br>
connectors, which are probably more susceptible to having the<br>
contacts burned than would Deans Ultra connectors.<br>
<br>
I have thought about putting a BIG capacitor in parallel with the<br>
arming plug, that would damp the initial current surge which<br>
causes the spark. The capacitor could be removed before flight.<br>
However, I'm wondering if there's a more elegant solution.<br>
