The "real" flying weight was going to be around 20 pounds, therefore we have used our 1/5 landing gear.
If your plane is going to be 15 pounds or less, we can make a lighter gear for around $305.00. Here are the dimensions for the CMP BF-109:

72 3/4 inch wing span (1850 mm)
18-20 pound flying weight
Landing Gear extension angle 87 degrees
Pivot to Axle 6 1/8"
3" to 3 3/4" tire
3/16" axle at 5 degrees
4 degree rake forward angle at the top of the strut
1/2" strut diameter
