Default RE: tail dragger conversion


ORIGINAL: Whirley Bird

My CG is fine and the plane is in proper balance.
Where I screwed up was I used the landing gear for a lighter plane and the nose should be higher.
I never measured it but I think if I had 12* instead of the 20* shown I consider myself to be lucky.
I wanted to change the landing gear or go with bigger/thinner spoked wheels but it flies nice and I don't have a problem.
I will take that measurement later and let you know what it is.
Thanks for the information

The CG is always worked out according to how the airplane is to fly. The importance of the CG is in balancing the airplane in the air. If it's not in the proper balance in the air, it comes back down. No matter where the gear is attached.

But to place the tires where they give the least chance of problems, they are positioned relative to where the CG is not the other way around.

Shorter landing gear will place the footprint at a different angle than longer gear places it. In fact, with your short gear it needs to be attached further aft simply to keep the footprint from being too far forward. The length of the gear also has something to do with where the gear should be placed. In the case of your model, if you plan to swap out that short gear for longer, expect to get different ground handling. The posters who've suggested that the gear is too far back are probably advising you based on their experience. And they probably used "normal" length gear.
