Gaui NX7 receives a new heart

06-14-2016

After seeing the new YS96 SRX Tareq engine in action at the Orlando Helicopter Blowout in December 2015, I had to have one. I originally ordered one from RC Japan, along with a YS 96 Power Pipe. But they have been delayed for a few weeks, due to a slight manufacturing issue. I was checking out the for sale listings on a major helicopter forum a few days ago, and found one with a handful of flights for a great price. I bought it, and I just received it yesterday ( Monday June 13, 2016). I am now waiting for a second YS96 Power Pipe to get here from HeliDirect. As soon as that gets here, I can get the engine installed and proceed with the break in process.

The YS96 is an amazing piece of engineering, and displays the quality that YS is famous for. One thing that I found interesting, is the fuel regulator is mounted on the engine housing below the carburetor instead of on it like the 60SR.

Another thing that I thought was strange, but at the same time kind of neat, is the way the pipe mounts to the engine. Instead of the pipe mounting holes going clean through the engine housing, they are threaded. Which means the screws which hold the pipe on, will go in through the flange on the pipe and screw into the engine housing.

I do kind of wish that the back plate was not steel lined though, because I like to use back plate sensors for my governors. I guess I will be using a magnetic sensor on the NX7 now, which is ok.

I should get the Power Pipe by Friday, and maybe....just maybe I can get them installed and start breaking the engine in this weekend. I can hardly wait to get it going and broken in, so I can feel the power of this awesome new engine from YS.

*One other point that should be addressed, is an error in the manual. The manual says for break in, to set the Hover needle to  1.75~2.0 turns open and the high needle at 1.50~2.0 open. These settings will be way too lean for break in, and it was suggested to me, to set both needles to 2.5 turns out for the break in flights.*
