Sub 2m Hi-Start Rubber
Works extremely well for launching my 60" span 1.5lb Ptero thermal glider. I was concerned about snapping its small wings, but this hi-start does exactly what the tech write-up says - a steady, gentle pull. I rigged it with 1000ft of 100lb monofilament, which was far too long (longer lines demand more pull). I'll shorten the line soon to ~500ft which should help. Even so, I still get higher launches than my buddies using the Dynaflight Hi-start. The stretch of this hi-start rubber is impressive - up to 700%, so you can fine-tune the tension. Even at max tension the launches are steady but controlled. Many would scoff at the price of good quality hi-starts, but you really do get what you pay for. Shipping to Canada was affordable and trouble free.
I give this product 5 stars. Review by Henrickson, Lawrie
