Thanks so much for your kind words.

One of the problems of course with a tri-cycle gear model is to get it to sit on all 3 wheels as the CG without the weight of the real plane's equipment makes the model tail heavy. I put some weight in the bottom of the nose turret and inside the nose wheel itself, but what seems to have really helped is that since the engines all sit forward of the main gear, I stuffed a bunch of washers behind each firewall hoping the fact that it was quite a bit of weight would compensate for the fact that it was only slightly forward of the gears. I'm hopeful that it will be enough.

Having an aircraft with the CG right at just barely in front of the main gear would make landings and take offs pretty tricky for sure.

Hi Tom - I've been lurking in the shadows and just want to compliment you on your beautiful workmanship . Nice to see another post - hurry up and get the basement done so we can have more !

As an aside I have watched the Collings Foundation B 24 on several occasions and have come to the conclusion that it's center of gravity must be exactly over the main landing gear as I have never seen an an aircraft hobby horse so much while taxiing . Almost made me seasick while watching !

Cheers - Richard




That's interesting, and probably shows just how bombload dependent the thing was for balance...

That's also probably why the C-87 transport was so finicky (and was almost grounded after 2-3 accidents). The bomb racks set a regulated center of gravity, but a transport could have deadly variations if you were not careful...

That makes sense. It appears the bomb bay is pretty close to the main gear (give or take) and that would help to keep the CG in the middle to forward part of the A/C.
