Hi all! Am trying to thin out my collection a bit...too many kits that I won't be able to get to.

Selling a Flight Systems Inc MRK V OSo kit. It appears to be from the 70's or early 80's based on the packaging and the address (Louisville, CO crossed out on the kit header).

The model is designed to fly on FSI motors, 21mm D/E's or 27mm F's...could easily be adapted for 18mm or 24mm motors. 29" long including a large payload section. The kit is mint, sealed in the package and would be a great addition to your fleet...or collection. It launches on 18mm motors.

Asking $80 including USPS shipping.

Would love to help this kit find a new home! I take payments by PayPal, Venmo, check or most other common ways. Will be well packed and shipped quickly by USPS.

Thanks for checking this one out!
