RE: Micko P-47: build
It's not a set of Glennis wheels... These wheels weigh 8.0 ounces each. Weigh the dubro wheels and I bet they weigh the same.
If you want the lightest wheel then go with a Yellow Aircraft 5" wheel. They weigh 4.5 ounces each. Hub and tire.
You chose Sierra gear, which is the best, not the lightest though.
Your Bird is still gonna weigh in at 30 pounds no matter what wheel you use.
Looking forward to more pics of your build.
Good luck.
