Build it with balances like martyg shows.

As for coupling, it has almost zero. I use about a 5% mix to eliminate the roll, and I do not recall any in pitch. Any intermediate pilot that practiced it a few times could do a KE loop even without the mix. I did my first Sledge KE loop on the test flight, with no mix, at about one minute into the flight.

This plane makes confidence for you, as clearly demonstrated by the number of Monokote patches on mine.

Order it, and build it as light as you can. All Pro Bros owe themselves a ride on a Sledge.

And no, I do not work for Jeff or Morris. If it sucked, I'd say it sucked!
