HelicopterThunder TigerOther › Is the 8.73 Titan Gearing Changing My Tuning????

I installed the Titan gearing into my R50 recently and have immediately noticed 2 things.

1. The heli is MUCH harder to bog down under load
2. My mixure seems to be SUPER, SUPER rich.

I have only been flying nitro for a few months so motor tuning is still a bit new to me. I shot the motor with a Raytek and the hottest that I was getting was about 185 (on average) degrees. This was just under the blue Hyper head. Before I started leaning in on it, the highest temp I got was about 145.

I realize that the motor will now be running at a higher rpm for the same rotor speed, but would just the gearing change make this much of a difference? I'm talking like 5-7 clicks of difference on the high end.

Heli Specs:
R50 SE w/ Titan upgrades
OS 50 Hyper running CP 30%
MP2
GV1 set to 2000 rpm on the head

Any help or insight would be greatly appreciated.

I did not have to change anything on my mixture setting. I did however have to put the new gear ratio into the gov. I am not sure if the gv-1 needs to have the ratio programed in you might want to check that.

Didnt have to change anything on my motor, just change the gear ration on my governor as well. Went out and just flew it, can we say Pop Pop?

185 after landing is as much as I'd want to push that motor, the actual inflight temp will be 15 or 20 degrees higher, plus the brigher the color the less accurate a temp gun is.

Yes you will have to reset the ratio in a GV1

I did reset the ratio prior to flying. Barracuda, what did you mean by the brighter the color the less accurate a temp gun is?

I checked the Raytek against my on board Venom, and they were within about 2-3 degrees of each other. I realize that they BOTH could be off, but I was just curious what you meant about the color.

Im thinking that he might have meant the blue color of the head. Although I shot the motor just below that area on the grey metal portion.

With an IR temp gun the color of what you are measuring can effect the reading you get, it has to do with reflectivity of the surface. I use the Venom but I have a gun as well.
