Hi Scotty, I have built a couple of Five jets over the years.
I flew my first one with a Wren MW54 12lbs thrust.
I lost that when it tip stalled coming in for landing.
My second one had a MW54 14lbs thrust which made a lot of difference
to the vertical performance.
If you let me have your address i can photo copy the review and post it on to you.
You can find more info on the web site http://www.arrakis.es/~rcpalma/Five-Jet/
The jet is quite easy to fly but floats on a lot when trying to land.

Rgds Martin
