Your getting 2000 winds into 2g of single looped 1/8 rubber? That sounds absolutely preposterous but who knows, maybe it's not a typo.

Definitely try lower pitched rotors. I have 1 inch vertical spacing - 1.625 inches is too much.

possibly preposterous. there is a small chance that it isn't 1/8th rubber. It was rubber we found in an unmarked box from wright stuff a few years back. I tried measuring it, and its close to 1/8th. But we got 130 winds on our 15:1 winder.

two THOUSAND thats inconcievable and only :20? I can't even comprehend what your heli must look like to handle that much stress especailly on such thick rubber

Okay, so i should conclude that i do not have 1/8th rubber then. Because i just counted and my winder is indeed 15:1 and i did wind it 130 times. my helicopter is only four grams, and didn't have too much trouble handling the rubber.

that must be something really minute, how are you lubricating it? that may have to do with it

yeah thats fairly standard. That and silicone grease AKA armor all.
well I have 0 clue how your getting 130 winds on a 1:15 winder. That rubber might be really stretched out so it doesnt hold much energy. Thats my guess. b/c to get that many winds theres not much elastisity and if your only getting 20 seconds theres almost no power. I wouldnt use that rubber...ever

that may be the case, each loop is able to stretch well over six feet.

Now i get to find, buy, get, and test new rubber in the next week before state.
thanks for the help. should i still persue 1/8th inch rubber do you think?

Definitely, it's thick enough that if provides enough torque to lift most copters, and it can take enough winds for duration. Go for it, and order it fast.
