Just got mine.
Beautiful head. I installed on my T700. Do I need to drill another hole or elongate the stock hole of the fan shroud to reach the angled plug ?

Had time today to put 6 flights and the difference in power and smothness is noticeable. Definitely worth the money. It seems to run cooler also, I´m just measuring in the same spot as with the stock head. Actually the head has bigger fins, about 3 to 4mm longer. The only downside is the even cutting the plug hole all they way to the bottom on the shroud is really hard to remove the angled plug. I was able to grab it with my flexible Vario wrench, but didn´t tried to remove it since putting it must be harder

Dual plug heads
Quote:
[Real] piston airplane and heli engines (made by Lycoming or Contenintal) all use dual plug for many reasons - some required by law:
I am buying one to see/test and report on |

Now I have about a gallon on my YS91SR-3DS with Betta's head and is running great, a bit more power on mid and even smother than the stock head. Running with two OS8 glow plugs. Very happy with this mod
