Anyone know the optimum temp for the OS 32 engines in the winter? I'm going to be using the Venom Temp guage with the sensor near the base of the head.

I would forget the Venom, and tune it to run well. Finger in back cover is the true temp test.

during the winter the os 32 will seem more like a 46, they're a pleasure, but do like al says, forget temperature gauges, just tune it for best power, then fly around hard,then land and hold your finger on the backplate for 5 seconds, if you can do that without burning yourself your right around the right place.

Then look at the Venom gauge, to see what right for you is!

gyan, I agree with comment others have made here on checking and seeing what is right for your machine. That said, I have a Venon on an OS 32 in a JR Venture. The temp on the Venom at 30 F outside airtemp is around 200F. That's about 20 degrees cooler that when it's 70F outside air around here. Hope that helps. I can't say that is optimum, just what works for me.

Also I am running 30% Coolpower with Enya #3 plug.

Cool guys thanks for your input. I like verifiable data & the venom can do that during flight, so I want to check it out without burning up an engine.

I run them at the same temp all year round. When it is really cold you can lean them up without overheating. Makes for great runs if you can keep the fingers warm. Blades bite better too.

Tune with your finger and ear. Use the venom to keep it locked afterwards. Just shooting for a number isn't reliable as they vary quite a bit from position and placement.

Good Luck,

Mike

Thanks MJWS . Hey Ethan, considering what MJWS said about placement where did you put the temp sensor? I'm running an Enya # 3 as well but with cool power 15% Would that change the temp reading?
I would like to fly with sight of exhaust, sound of the engine & touching the backplate for 5 sec as suggested but I'm fairly new to all this so I need a ballpark range to work with. I almost fried this OS 32 a few times, & the engine flamed out on me a month ago, so I want to reduce the risks , you know what I mean???

Every variable changes the temp, that's why it's not a good indicator. Start rich, lean it until it performs well, and the back cover is warm to almost too warm to touch. 32's need to run warmer than 50's/60's etc. Again, the only thing the Venom is good for, is to see what temp is right, for next time. But you need to find that temp without the Venom.

gyan, I run the sensor snug up against the base of big cooling head on the OS 32. The red thermocouple area of the venom wire is facing the ground on the Venture 30, kind of 180 degrees away from the cooling air that is being blown on it by the fan.

MJWS is correct you can lean it a couple clicks and get a little more horsepower in the winter. I think mine runs fine as is so I don't lean it any more.

Remember what others have said here. It's only a guide and you shouldn't use the readings as the only means of checking the engine. Also check that the thermocouple is always snug up aginst the engine head to get a good reading. It will work itself loose after a few flights.
