Telemetry Temperatures

[Rctintin]

Jamie, I am sure I remember Bert Kamerer saying about engine temps somewhere. I'll have a look around and see if I can find it

Yes, I seem to remember it being about 100c when measured on the cylinder wall, where it meets the cylinder head.

I suspect that it is going to have a lot to do about where the sensor is installed.
Since the head temps are going to be hottest.
Does the OS not say in the specs anywhere?

Temperature alone isnt a very good indication of mixture. Sure backplate temp is a nice final check but nothing comes close to getting to know what your engine sounds like when its on song and adjusting it yourself either through a servo operated needle or by landing it.

Because of this the dx8 telemetry is only really useful as a "theres something wrong, land now" device rather than a competitive advantage.

carbsmart operating range. 100c for running in. 110c for maximum service life of engine. 115c for max power

on my DX8 and V90 I saw 120-130 degrees during setup on the Friday with Rob helping me tune it for power. This was on an OS91 HZ.

OK, I emailed Bert Kammerer yesterday, and I have a nice long reply from him today. (thanks Bert)

As been said already on this thread, around 100 deg C is the optimum temp for IC engines, and should not exceed (220) 105 deg C. This should be read right below the head where the head meets the the crank case. The temp being measured is going to be different depending on how it is measured because of the type of surface, and readers being calibrated differently for different types of materials.

Berts suggestion is to tune your engine by ear as we do now, and see what the temp reading is on your telemetry. Now set your alarm for 5 degC higher.

What minimum temps are people setting up?
I get a Alarm when I turn on
What am I doing wrong?

Might be a daft question is the temp sensor plugged in because it alarms when its enabled but not plugged in, Or make sure your min temp is set low enough think mine is set to -5 lets me know when its to cold for me to fly

I have it plugged in was well happy when it told me the room temperature
It's a bit late to turn the tranny on with all the beeping.
will look in the morning

I don't see the point of an alarm on minimum temp? I've just Inh it, don't care if its cold, only if its about to explode cos its too hot
