Here's my progress on the gas engine installation. The engine arrived yesterday and came with the correct length standoffs, bolts, prop washer, and prop nut. It also came with a huge muffler. As you can see by the photos, the muffler would not fit inverted (too long) so, until Ifind a drop down flex pipe that will fit this engine I've mounted it as in the picture. I intend to fix an exhaust deflector to the top of the exhaust pipe to run it completely out of the cowl. It looks bad but, it fits well and will work until Ican find what Ineed. Isearched the web last night to find a 90 deg. drop manifold that would fit a 30mm bolt pattern but, no luck. I'll keep searching but, Imay have to fabricate something.
Fortunately, Horizon has parts left for this bird and Iwas able to buy a new cowl and fake engine so that when I do correct the exhaust mount I'll have a cowling to install that's not all chopped up.
I chose to use the same method Minnflyer used to mount the EI but, mine will mount under the platform as it will interfere with the cowl if I mount it on top.
I'm not happy with the appearance but, it's better than not flying it at all. Ineed to plumb the fuel tank for gas and get the electronics hooked up. Then we'll see how much, if any, weight Ineed to add up front.
