Hey Knight gangs,

I just place the same question on the engine forum but since this engine is intended for a Knight 50 Sport, I will ask here too

I dont find the post but I am pretty sure I read here at RR that the back plate touch method does not work with the YS50......... That in order to set up correctly this engien you need a temperature tool for this.

So you YS50 users, can you coment on this.

I will receive my YS50ST next week since I live in Central America but I just want to be sure of this to be ready when the engine arrive.

THX

If I were you, I would pick up an inexpesive infrared thermometer. You can find them for about $40 now. I use one and check the engine where the head/crank case meet. I usually shoot for around 200* F.

I have not received yet my YS50 but I am planing to install a on board temperature digital monitor with memory.

What you think?

That will work too. I have seen the Venom temp guages before. One of the best features is that it will give you the actual temp. of the engine during flight, since it keeps the hottest temp. in memory. This should really help you tune the engine for max peformance. I would shoot for around 200* F. While the engine can probably handle higher temps, I have found that there isn't much of a performance increase when you try to get max engine temp.

I do not use a temp gun myself but once my friend beamed his gun at the crank just below the heatsink. It read only 60C which is about 140 (?). At this temp, I could put my finger at the back plate for a few seconds.

When I raced RC car, we aimed for 200F but it was taken at the glow plug which is substantially hotter than the crank. I would not aim for 200F at the crank for a heli engine.
