The guys at FLAPS (Fast Little AirPlaneS) have developed a custom nosewheel fork that allows for a larger nosewheel on the Tri-Q. This will allow you to insert a nosewheel with a 5 inch width instead of the standard 4 inch width. This is for the nose fork and axle ONLY. Tire and rim NOT included.
A larger diameter tire will increase your ground angle of attack, and will help reduce "wheelbarrowing" on the runway before liftoff. This custom nose fork is $400 and will ship via USPS priority mail.
Lead time is 3 days. Shipping is $20 in the Continental U.S.
