Bax,

I'm getting a new 1.40RX. I have a couple of questions on proper break-in.

The manual states:

"Start the engine and open the throttle. Close the needle-valve gradually and allow the engine to run at its maximum rpm for just one or two seconds, then immediately reopen the needle-valve a half turn and run the engine with this rich mioxture for 5 to 6 seconds. Repeat until tank is empty.......not more than 10% nitro."

Here are my questions:

1. I only have 15% Cool Power available. Can I use it or do I have to wait until I can find some 10%.

2. The above sounds like you start the engine, run it up to full throttle, then go crazy playing with the needle going back and forth until the tank is empty. Is this correct - wide open throttle.

3. If I do this one tank ground break-in, can I then go direct to flying and just keep it tame for a couple of tanks.

4. Any general comments on break-in are really appreciated.

Thanks, Steve.
