What might I be doing wrong? Every time I take it out to fly I get no glow. Replace the plug and fires right up. It's not lighting. Is it the way my engine is tuned?

My needle is like 1-3/4 I watch my head temps.... around 200 deg at worst case.

Didn't burn up plugs till I went to the Switch glo. The audible beep tuns off after 10 seconds.

Sounds like the Switch Glo then. What kind of plugs ? Some are less tolorant of overvoltage then others.

OK forget it about the Switchglo for now. My YS took a dump. catastrophic bearing failure. Parts of the bearing cage chipped the thin flange on the crank and some small metal chips were on top of the piston. Engine is almost a total loss. The engine problem was most likely the cause of the glow plugs going as I was getting strange performance behaviors as it was disintegrating. It started slow, took about 10 flights before the bearing blew apart and I realized the problem.

I'll put my spare YS in and an continue using the Switchglo.

It must have been a coincidence that the bearing started going at the same time I installed the Switchglo.

You have to drag out every bit of information from people posting, it would be nice if they would just be honest and say everything that was not in the norm. They could probably save themself a lot of grief and money.

Anybody need to know anything else before i get more complaints?

I want to know who is being dishonest... we got straighten that fellow out.

Yea there was a rough noise when the bearing went. We couldn't see inside the motor or I would describe what the pieces looked like crunching through it. Some of the balls were missing. Not sure how they got out.

Engine temps.. at the head kept in the vicinity of 200 deg. Less than 5 gallons through the motor.

600N with max head speed of 1950

Sounds like a warranty case - hope you bought it here. Did it ever run right? How much fuel did you put through it? Sorry for your misfortune, but watching the temps as you did leads me to think it was a simple part failure. I hope you can get it fixed before your winter sets in...

i only just burned up a plug in my ys 50. it was about a 2 gallons old, just under. i was flying around, doing the normal 3d stuff when all of a sudden the engine quit. got it autod into the hay field and looked and the first coil on the plug element had burned off causing the engine to quit.

i dont know why it happened, my hyper never did this to me in flight. i was running the ys 50, mp2 and an os 8, running off a regular nicd glow starter.

Burnt GlowPlus....

Hi, I thought I was the only one having problems with overheating and my YS50 eating plugs.....

I installed a heat sensor to help me in determining how I should re-adjust the main & Idle needles.

I'm only flying with 15% nitro (22% Oil), and a #2615 muffler from Zimmermann...

After a lot of trial and (mostly) error.., I now have an engine that gives good response and power when needed. My Idle is at 2 clicks (towards) closed from 3/4 open, and main needle is at '46' clicks open - I think thats almost 2 turns open.

My max recorded temp is about 110°c - 125°c (230°f - 257°f) - the sensor is just below the head cooling fins, 90° offset from the exhaust port.

My temp before was way up there, 150°c (302°f)

I've tried the following plugs:
- Enya3
- OS8
- YS2

The Enya3 seems to do the best at keeping the engine running, when its over 24°c (75°f). But the OS8 does well at lower outside airtemp.. the YS2 I couldn't get to work very well.... maybe if I ran 30%N it would do better...

If anyone else has a better idea why the YS50's are eating plugs and over heating it would fun to hear about it, and how you solved the problem....

Happy Flying

Hootowl I did not say you were dishonest, you know it it was meant to mean all the information you have about the engine was not stated. Things like less then five gallons through the engine, did the engine sit for a while before being used again. Things like you said about the head temps rpm and ect., all can be bits of information that can be helpful to the person trying to help. Why not tell us all you know first, is all I am saying. Took the reply the wrong way was not trying to be a pain, but it is hard to beleive that no noise from the bearing was evident, but you may not of heard it. I would send the engine back it will probably be covered. You say arguments get extra credit.

And you get extra credit!

Yea I did begin to hear it a few flights back but wasn't sure what it was. Couldn't believe a YS would take a dump so fast.

Here's another revelation. When I removed the motor last night I found the two screws that go up through the base plate into the motor mounts WERE MISSING! Now I don't know what happened first but without those two screws the engine is able to vibrate an aweful lot. Did the screws come out first and cause the motor to vibrate to destruction or did the bearing go, vibrating the screws out?

I will never know the answer to that one.

No prob airdodger, keep up the pressure cause we do need to have all the facts up front. Maybe I should wait till the whole ordeal is over intead of guessing along the way.

BTW the manual says start with main needle at 1-1/2 turns and the low speed needle at 1 turn.

my needle is just over 1 1/2 turns out, maybe 1 5/8. (about 4-5 clicks past 1.5) running 30% nitro.

hootowl:

I had the same problem as you with missing screws :/. I loctited the ones that came with the kit (cleaned with alcohol etc) into the landing skid holes and the had fallen out by the 14th flight. i noticed when there was only the two rear screws holding the heli to the skids and the tail was rocking up and down with the heli sitting still.

i think my plug was a random issue caused by the engine break in but i'll never know.

in any case, good info we're getting here. now is the colder part of the year (getting around 15c regular flying temps, then lower down to 5 in oct). next time out to the field i'll bring the temp gun and measure different parts of the engine.

Well it looks like for sure the problem was a bad motor with small metal pieces on top of the piston that came from a disintegrated bearing. Apparently the metal pieces in there were creating havoc with the glow plug.

Got my spare motor in, loving the power and love the convenience of the Switchglo.

My apologies to Switchglo for making assumptions. It's a great product and works as advertised.

Bummer. It's still early in the game to see if the ys eats bearings like the os. On a side note the switchglo is the best thing since sliced bread. I ran out of fuel and autoed into a corn feild. I kept flipping it on to find it.
