Helicopter Testing

Age is important, but probably more important is storage conditions. Rubber hates heat, light, ozone. Oh, and some plasticizers used in some plastic bags degrade the rubber. Unfortunately I can never remember which ones so I tend to store my stripped rubber in envelopes. Otherwise I like to store my rubber in the original box in a cool place in my house away from electric motors and other electronic equipment (ozone source). For real long term storage, freeze the rubber.

Oh, and remember what we said about Tan Sport vs Tan Super Sport. Super Sport will store more energy, ie take more turns, than Sport. Thus the recommendation to stick with Super Sport.

And on top of that, some batches are better than others. Either in energy storage or in inconsistent breaking.

Hm, I guess my basement was okay, then. I've been keeping them mostly in the original boxes, and all of my rubber is Tan Super Sport. I'm running a little low though, so I'll probably stock up again with new FAI rubber anyways.

On the subject of FAI, it arrived today (surprise to me). Although never did hear back from the owner, but it worked out so no biggy I guess, just a bit interested in why no response/really long time to ship.

On that matter, since I now have rubber and finishing up my rotors tomorrow I can *actually* start testing now... only took, what? 2 months?

Hi everyone, for states I'm looking to being able to test my helicopter in a more scientific manner than before, especially for torque. I know there are a lot of plans on the internet to build your own torque meter, but I have REALLY minimal building know-how and tools. Does anyone know of any place where I buy a pre-made torque meter?

Indoor Model Supply used to sell one, but when I checked on the new site A2Z Corp I didn't see it available electronically. You might send an e-mail and ask.

I'm not aware of any other commercial sources. However, it is REALLY easy to build one. A number of plans are available on the web:
http://www.indoorspecialties.com/articl ... 0Meter.pdf is pretty simple
http://www.modelflight.com/torque.html a little fancier
and others

Finally broke 2 minutes on an 8 ft ceiling! Main problem is the bumping into walls... my best copter is pretty stable but still wanders around a little.

I'm sure it will find its way to a special place in the dumpster out back your local UPS store :D
