Building a GLH II, CG question
Hi, I'm building a GLH II from an old kit and I'm close to finishing (pics later tonight). My question is: should I balance it with a full tank or with an empty tank for better glide when the engine shuts off?
I'm using a 1oz tank and a TD .051 with no throttle. So, it's gonna fly until it's empty, hopefully. |

Empty! If you do it full, as the fuel burns off it will become tail heavy. A nose heavy plane flies poorly, a tail heavy plane flies once.

Yup empty. Rubbernecker is exactly correct. Nice GLH, Dave!

Ready for maiden flight. The kit called for foam sheeting on top and bottom of fuselage, seemed a little flimsy for my taste so I replaced it with 3/32 balsa sheet. Left the wheels off. The specs called for an all up weight of 20 oz, That would have been with 30 year old radio gear, as it turned out all up is 15oz. with no fuel. TD .051 with a 1oz tank. For an older design this puppy should be pretty quick, I hope.

That looks great! Hope she flys as good. I have an old kit that is partically built that I played with a couple of weeks ago. The die crunched ribs were so bad, I will cut new ones. Good luck.

Looks like you are light enough, that's for sure, but George Kurreck flew his GLH's with foam top and bottom, just fine.

No disrespect to George's original design intended. My motivation was more because the foam in the 25+ year old kit was a little beat up when I got it, plus I am not very good at sanding foam and I only had high temp covering on hand. I was more concerned about any negative effect I might create with the change.Hopefully it will still balance out and fly as well as the original.

Its all good
Wow
Nice covering job. With the weight reduction you have the diference with balsa instead of foam should be nuttin' worth frettin' 'bout! Makes me wanna break out my GLH from the collection shelf!
