I have one with a saito .91 on it. I mounted mine inverted straight down. I got the flexible pipe from horizon and ran it down and out the bottom cutout of the cowl. I wound up cutting a little in the front for more airflow (the head of the .91 saito doesn't really make it down into the opening). Made a little lite ply brace on the bottom of the motor box to hold the flex pipe towards the end. TO get the throttle where it would really work half way decent I had to put a decent size hole in the firewall and ran a ball link attached to the arm and a metal rod to the servo (mini servo which I made a mount for right behind the tank).

I'm taking it down tomorrow and will take some pictures if I get around to it and get the cowl off. I ran it for the first time last week and put about 1 1/2 tanks thru it, still need to track down some range check problems before I fly it soon. Came in lighter than I thought it would 7.4 pounds all ready to fly minus fuel and that was with 3 oz. of weight on the firewall to balance.

The plane came out "ok" but really the covering was a pain - nothing you do can keep it non-wrinkled. It's the wierdest thing I've ever seen on covering. Most that wrinkle you either get the wrinkle out permanently or it never unwrinkles. Not this stuff, after you shrink it down and go over it with an iron after the gun - the wrinkles come right back in a day or two.
