Our engines speak for themselves....
and Jett pilots have a lot of good things to say too! |

"This is a photo of my Jett FIRE 90L with a 15
cc MACS quiet pipe. The Jett machined test stand is bolted to a pre-fab bookshelf which is in turn bolted to a
shop stand. Both were purchased from Home Depot. The shop stand cost about 30 bucks.![]() The 90L turns an APC 11X7 at 16,200 on Sig Champion 15%. This is significantly better than your advertised numbers for the larger 95L. |
On the day I checked the 11X7 I was able to turn an
APC 10X10 at 16,000 using the same fuel. On a previous test session a few weeks ago I got 16,300 with the 10X10.
![]() For anyone interested in duplicating the setup the total length from the back of the exhaust spacer to the tip of the pipe is 23 inches. This seems to be optimum as I got no more gain from another 3/8" cut which I put back in. The engine starts, runs, and throttles perfectly with the most instantaneous response I have ever seen in a glow engine. Overall another fantastic Jett engine!" Gene Greatti |
