Confusing

Flyon as I said I need to setup my mill which just came in, then I will show you how much mass is taken out of Raja piston,
How does your mill know how much mass Hanson took out of my piston?
this important to show why his 3d max stroker show a heat soak
Mine didn't. It was someone else's motor with that chart not my motor. But granted if I put an eagle tree live downlink on my engine I could possibly see it too for the 15 seconds or whatnot, maybe less as my piston is lighter than the stock 231 piston that made that chart.
As for the eagle tree, simple it uses a contact probe which is pushed between the fins I have use a Vernon which uses the same type of probe and could not see the affect.
So you're saying Wally what with the Vernon temp guage with a permanently mounted sensor to the cylinder you couldn't see the heak soak? Interesting, I thought that might be something next to try as running to the heli after landing is too late to detect it with a hand gun.
And I said it may not work I didn't say it would not work, but when I put it near the outside of the fin I could see the effect,
Now I'm confused. Yes or no? Could see it or couldn't see it? One sentence says yes, the other says no.
and remember with a heat gun you are only see the temps on the tips of the fins not the cylinder walls
I'm not sure I agree on this. I've used several guns and some with laser pointers and I get different readings if I put it on the tip of the fin versus on the cylinder wall in-between the two fins. Finally I decided not to pay attention to where just search for the hottest temp found and go with that as that's all that counts, anything cooler is irrelevant.
So as soon as the mills setup and leveled I'll start making chips
I just had to ask, and me not knowing the terminology, is this something you eat? I know absolutely not, but what are chips anyways?

I just came back from flying, which is what the bottom line of this whole hobby is. Breaking in a new motor I ran it at 11,000 also for a whole flight and checked the temps, also running at 210F just like CNCJunkie, which confirmed my thought that his temps are low due to easy flying during breakin.

It's a milling machine, and when it mills metal,, there's chips!!!

Come on guy's lets get on down the road, This HEAT SOAK discussion has run it's course, It happens, It doesn't last that long, So really no big deal, I still think that a person should let it cool down for 20 to 30 seconds after you landed, just to stabilize the temp, then kill the engine,
Raja has been flying gas engines for quite some time, as I have, He doesn't warm up or cool down, and his engines last a long time,
I do warm up and cool down, and my engines last a long time,,, So maybe these engines are a little more resilient to the stress that we put on them,,

I love the gasser fourm as most of time we are above all this name calling, and he said this, then that,, Lets get back on course,, and hopefully something constructive (Bigger and Badder Gas Engines) will prevail.. XGM/VGM

Flo Pro?

Anyone use the Toro Flo Pro sprinkler valves? They don't like to stay closed when I put air into the system to blow out the lines...I think I need new diaphrams but not sure if its worth it or better off to change them out to something else. I read on-line they are not the best...

Toro Flo Pro valves are prone to Cold Soak. With the weather cooling, as we have right now, the valves will not close all the way. This Cold Soak phenomenon is very difficult to measure; with standard measuring equipment being ineffective, so you're stuck with an open valve until the weather warms up, or you could use a heat gun to warm the valve.

However, using a heat gun may destroy the valve.

As long as the soda doesn't go out your nose, you'll be ok. Otherwise your going to feel the burn...

Maybe you should stick to milk or water while reading RR posts just to be safe.

You don't want to get that on your Toro Pro Flo sprinklers it will just gum them up...

Where have we gone now with this...

That sounds like overkill

I'm trying out the 7966 servos, 100oz at 5.4v with my Jewel (rated at 92 at 4.8v and 111 at 6v) and they are 0.095 speed in my bird. They are plenty fast enough and 100oz of torque on a heli is more than enough.

The main thing is, how long will they last? They need to go at least 75hrs/300 flights to compete with JR servos. I'm hoping for more.

Oh really?

Well that's good to know because currently I'm using 8311's in my 1005 and I thought I'd replace them with 8717's down the road. Sounds like if the hitecs work out with the Spectra I should get those for the 1005 as well.

hmm

Thats good to know. I was looking at those servos. I hate slop and I hate drift. my 8311's are just bullet proof. only draw back is almost too slow when you do tail down tick tocks.
