Thunder Tiger Champion-45S
 

I'm putting subject airplane. All information and instructions show the engine is mounted on it's side. The engine mount and the nose gear upper bearing is apparently made to mount the engine "heads up" or inverted. Has there been a change in design or do I have the wrong motor mount? If I use the mount that came with kit to mount the engine as shown, the nose gear will protrude out the port side of the Fuselage!

I would actually prefer to mount the engine "head up", but am concerned that the mound has built in angles that will be a problem and that the cowling may be a problem.

Anyone had this problem?

Thanks

Robin, sometimes there will be a "secondary" set of holes that will work for the nose gear when the mount is turned sideways. Take a look and see.

Ernie,

Thanks for the reply, you are right, there is a second set of holes, but they appear not to be for the nose gear. They do not line up with the main nose gear mount. They would have to be reamed out to line up. Also, the bosses for the gear are much sturdier and obviously intended for the gear. Use of the ones you are talking would be unsanitary at best. With my propensity for landing nose gear first, I want the toughest installatiion I can get.

I don't have anything to measure very small angles that may be built into the mount, but it appears to be streight. The "manual" talks about 2 degrees right offset. I'm thinking that I will use the mount as it appears to be built, for a "head up" engine. This would also have the benefit of protecting the muffler from crunches during my nose gear first landings! :)

Ace Hobbies has a customer service number for Thunder Tiger products. Even though I wanted to fly this thing this weekend.
I guess I'll wait and call them on Monday.

Don't you just love? these little mysteries? I think any thrust angles would be built into the firewall rather than into a generic mount.
