In my Black Widow thread we went on about the placement of my needle and I stated I was sure there were designs in the 60's and 70's that had the needle pointing up and the cylinder pancaked, well I finaly found it the Big Otto the plans show various types of set ups. Not to doubt anyone or stir the pot but I knew I wasn't loosing my mind... n~ #^ y1 <=

I don't think anyone doubted you, just observed that inverted landings will be a little hard on it.
Always good to have documentation, though...besides, I been wanting to see this "Big Otto"!

HI Dwayne,
There have been a lot of people who lay the cylinder over on its side with the NVA in a normal position. It helps with wing tip weight. I never have done it, I don't want to mess with rerouting the fuel pickup in the tank, etc., but I have flipped the cyl. inverted. The nose of the 1/2A Snapper dictated and inverted cylinder.
The problem, as you know, is in breaking the needle if she goes in inverted. That can be a pain! LL~
Good Luck!

Worse than breaking one is just bending it...then you're tempted to try to straighten it, and then it snaps off flush, so then you try to run it as is, and of course it vibrates out of position, which you try to prevent by boogering up the threads at the broken edge, which doesn't work, but jams the remnant hopelessly in the backplate, which means you've trashed one of your last metal backplates...not that I've ever done this myself, nosirreee...

Dwayne,
If you check closely, the engine in that plan is a BabeBee which was fueled and vented on the backplate and did not have stunt venting tubes. If you place that backplate on its side, fuel drains out.

Very good point.
