Default ModelTech Great Lakes Setup

Hi Guys, I know this thread is really old, but I have a bit of extra information on this plane. I inherited one from a fellow club member here in Oz, that had only had 2 flights - only 1 landing though! It went into a dive when the motor cut, and couldn't be pulled out. I got it in several pieces and put it back together, as per the original instructions, and found that it needed the 1lb lump of lead that came with it on the end of the motor mount, to get it to balance as per instructions.

I managed to get hold of a couple of magazine reviews from when it came out, and a couple of things in there, plus a couple of weird things in the manual, led me to believe that the C.G. given in the manual had to be wrong. I've now bolted it all together, with no mods at all, chucked 2 ounces of lead on the firewall to make up for the cowl which didn't survive, and ended up with a C.G. just over an inch further aft than the instructions recommend. I flew it on the weekend, and it seems just a touch too tail heavy. I'm thinking the C.G. needs to come forward about 1/4" at the most - way off the recommended.

Anyway, it flew pretty well - fairly gentle stall, nice low speed cruise. It was just a little touchy on the Elevators, due to being a touch tail heavy, and also changed its' pitch to nose high as the fuel burnt off. I think they'll both clear up with a minor adjustment. All I've got mounted in it is a brand new Magnum 52 four stroke, and it pulls along just fine.

I think it's a great little plane, just a couple of errors in the manual. If anybody wants to resurrect theirs, I'd be happy to measure and post the exact C.G. of mine, and I'll let you know how she goes when I've fine tuned her.

P.S. This is only my second plane since my trainer - so I'm no expert flyer!!!

Regards,
Chippie.
