The New Bill Hempel's Ultimate 20-300

50% Ultimate 20-300 (2-seat version)

This newly released Ultimate is designed for a 200cc-275cc motor.

The entire Ultimate wing design was made so flying wires would not be needed and assembly times would be fast.

2-lower carbon fiber wing tubes proved all the strength needed with a single C/F tub for the top wing.

The Ultimate was originally designed to be the smallest airframe possible for use with the 3W-275cc motor. I did this so this airframe would have the most available power to weight available for this engine/airplane combination.

We ended up producing such a strong and light airframe that this airplane has outstanding performance with a smaller and much lighter 200cc motor.

Airplane comes complete with the following equipment: C/F landing gear, C/F wheel pants, C/F wing tubes, C/F 6”spinner and tail wheel.

Airplane is canister ready. Super light-weight construction used throughout this design will insure a great flying airplane for your hanger!

Available now in Red/White/Black scheme as shown now and soon to be released Blue/Silver/Black
