RCPilot,
Of all the responses in this thread, I consider yours the most politically incorrect. ''tickle'' give me a break.
I (and I am sure among others) am sick and tired of the way T.O.M. treats others on RCU. No matter what he brings to the table, he is manipulative and condescending in his delivery.

The prop that split was a Zinger 22x8 on a DLE 55.It split right along the grain. This was the second flight on a new plane. I didn't realize that Zinger's weren't as stiff as say a Xoar or NX. I got them from Tower along with the engine. Now I prefer carbon fiber. I'm not bashing Zinger, but I'll never buy one of those again. It just goes to show that anything can happen so you should take any precaution that you can. If I had the Opto Kill on, I could have saved a lot of damage to the firewall.

I looked at all the redundant engine stop systems and decided throttle close + ignition opto kill to be the least weight and simplest Ron's use. Done. Will set up all my gasser's this way.

A longitudinal blade split on a wood prop is often generated by over torque of the prop hub screws. This is something commonly seen with people using wood propellers. If you still have the prop I'll venture you'll note the prop's center hub has been repeatedly compressed by the prop washer, causing the incremental development of grain separation. If you have a deperession in the prop hub, you may have found the cause of the split. There is no reason to compress the hub of a wood prop where multi bolt hubs are used. A single bolt hub should have an indexing pins, or pins, to permit correct torque of the bolt or nut while preventing prop slippage. Unfortunately the use of indexing pins on single bolt hubs is a very rare thing. Many that did have them removed the pins to eliminate prop drilling.
Such a split can also be generated by a relatively minor tip strike during a botched landing. Any contact of the propeller with another hard object, engine running or not, should be cause for a very intense inspection of the propeller. I've split a prop just getting a plane through a door way while mildly catching the prop on the door jamb.

I've read all 4 pages and every post. I don't agree with how some people handle - perceive - the information, but I also don't see any reason to edit or whack posts. Some guys tell it like it is and other guys don't like that because they'd rather the information was delivered with a tickle under their crotch. Me thinks a few of you are too PC and should just grow up and be men about it.

I use the opti-kill.
Saying you accidentally hit it while flying is
much better than admitting to poor engine tuning skills,

ORIGINAL: Diablo-RCU
I'd be more interested in finding out why the prop split. Was there prior damage from a strike or was it damaged during mounting to the engine? What brand of prop? Flying prop blades are much more dangerous than an engine that won't shut down. If a blade comes off in the air, the engine may detach before you even hear it. No engine, very tail heavy......instant crash.
ORIGINAL: bruceal
I had a situation where on the second flight of the day I thought that I heard ''flutter.'' I immediately went to land, when I tried to throttle down I realized that I couldn't. Then all of the sudden I saw my muffler fall off ( I Loctite everything), the engine just ran at a high idle for a couple of minutes then quit. I was able to dead stick it in and when I looked I saw the problem. The wooden prop had split down the center of one of the blades and threw the engine out of balance and vibated the engine right off the firewall. All that kept the engine in the plane was the cowl and the throttle linkage. Now I use an Opto kill switch!

I had almost that scenario happen. Seagull 90 Edge, with an Alphabet 26cc engine (I won't name the engine, because the company has redesigned the subject part). In flight, the prop hub broke, sheared, came apart, and the 17X6 APC prop, metal spinner and prop shaft departed the aircraft, but not untill ''several'' severely out of balance rpms litterally shredded the interior structure from the firewall, back. The suddenly severely tail heavy plane was brought down to a conventional landing, and then I noticed the engine was still running! My throttle kill switch lowered the engine rpms, but with no work to do, the engine kept up a fast idle. I walked over to it and turned off the ignition switch.I replaced the faulty part, the engine runs fine. I don't think an opto kill switch would have made any difference in anything.

the engine stayed running with no prop?

You are right, an opto kill switch would not have changed the outcome in this case. But this is an extreme exception, not your average throttle servo or link failure, in which case a simple remote kill switch can make a hell of a difference.

You may be right, however, I have been flying gas since 1999, both magneto and electronic ignition and have never experienced a throttle servo or link failure. Not to say it can't happen, just what has been my experience.

Well to me is like saying that just because I have been driving for more than 30 years without an accident I don't need seat belts and/or airbags. I had 2 throttle related failures in less than a year, enough to convince me. But to each his own.

Good analogy.
If one uses a good decision making process, adequate materials, proven methodology, proper preflight, and maintenance practices,the "pill" isn't necessary.

Do you have a hearing impairment? No disrespect meant. A valid question.

From my point of view, this thing about T.O.M. appears to be all about control. Splashing testosterone around wanting to be the Alpha Dog. If that is not the case then you can simply hit the little red hand with the word "Block" beside it under one of his posts and you won't see what he has to say. Quite simply, Don't Read His Posts! Frankly, I'm man enough to just tell him so if I don't agree with him. Now we may have to agree to disagree but that's how things are in this world. It would be a real dull place to live if we all liked the same blond, wearing the same red dress, with the same stiletto heels, etc etc etc and vice-verse for the ladies points of view.

Every choice has it's good & bad points.
It's a very good thing that no single group can force their preferred method onto another group....although a few do try.

When stuff started falling off the plane in flight, I was focusing (unsuccessfully) on trying to spot where the prop assembly may have fallen in addition to watching the plane. Never did find it. I did hear the engine idling after it got back on the ground, to my surprise, as I expected it to have stopped when the prop left.
I do have hearing impairment, classic male high frequency loss and wear aids for it. I hear mechanical and engine sounds quite well, but people speaking are a challenge. Too much shooting for too many years.

RE: Emergency Engine Kill... Choke Servo or Opto-Ignition Kill from Transmitter
Great analogy.... and they sell a lot of morning after pills. I think it works in favor of the kill switch though.. a backup plan, behind the backup plan. There would be a lot more little "airplanes" running around without the pill.
The world is not perfect... I know that I could have used the switch on more than one occasion so far... and did use it on one occasion. I have even had a nice belly landing with no damage because of a landing gear failure and had the ability to shut the engine down before touch down.
It is a tool. Another tool that can be used, and can increase the safety of flying the plane. Every gas plane I own will have a transmitter controlled kill switch. 5 planes that I have right now.
