Harshflyer I think you should be a bit more specific as to what engine and fuse you are using! Guys with a similar or same setup will then be in a situation to give you more accurate info!

I'm no expert at scale modeling, but my Benzin with G230RC in open air gives me about 185-190F.

Engine temp???? 2 replys? Does no one monitor engine temp????
Well thankks too Heli3Dflyer I had a number too go by this last weekend.

I never did the control temp before the fuse went on, but I did get low temps 185-200.

At one point I got up to 215.

Any more info on engine temp would be great.

This chopper , that chopper, this motor, that motor............
I like that everyone lists what they have, I just dont like typing so much, and I cant spell worth crap.

I not to sure about the OS 37 but on my OS50Hyper I have 100C (212F) as my max temp but I aim for 90C (194F). Above 105C (221F) and you start to get high wear on the engine. The temperature is measured on bottom side of the cylinder head (down stream of the fan). I have heard that the smaller engines can handle a little more heat but I have no experience with temperature measurements on them.

Don't take these numbers as gospel as it will depend somewhat on exactly where you measure the temperature and the type and size of the engine but it is a good starting point. I find the temperature measurement to be a very good tool for tuning the engine and it can also tell you if something is changing with the motor or fuel system.

Hope this helps.

Thanks Chris, those numbers help alot. I have burned up one engine, I dont want to burn up anymore. Trying to get my mixture right takes a lot of trial and error.

If they ran, I would run them, knowing well they were to rich.
Choke and puke on spoll up, force them up to speed and go!
So I want to watch the temp and get them as lean as I can.
Plus its in a fuselage, all the more reason to watch to temp.

That little $25.00 Venom temp gauge is the way to go. Very cool.
The instructions say to locate the sensor right were you said.
