<p>I have not heard of elevator flutter with the Zenith planes. Think that may be on ailerons only when cables are too loose. I did not use cables for ailerons. Chose to go with push rods. I am very happy with plane @ 112 hours in 22 months. Have had a few issues with Jabiru. I used the connectors for alternator that came on engine and I guess there was a high resistance crimp as it overheated and melted the wire which caused a dead short and burnt out the alternator.

I am very happy with plane @ 112 hours in 22 months. Have had a few issues with Jabiru. I used the connectors for alternator that came on engine and I guess there was a high resistance crimp as it overheated and melted the wire which caused a dead short and burnt out the alternator. Both connector pipes to muffler cracked. One all the way through. I have rewelded and will keep a good check on them. And oil pressure sender failed. Before I even flew the started solenoid failed. I am not impressed with Jabiru quality. That being said the engine itself is perform well so far.</p> Hi Joe,

<p>Hi Joe,</p>
<p></p>
<p>Simple and elegant solution to heavy elevator. I like the mounting by the elevator horn and the adjustability of the rubber bands. The rubber gives it some damping against possible elevator flutter- or am I over thinking this?</p>

<p>Hi Joe,</p>
<p>Borrowed your rubber band idea for my 601XL and installed this weekend. Worked like a charm but I am probably where you were after your first test flight - huge improvement but not quite hands off with full flaps. I originally did the spring on the stick thing but wasn't happy with all the load it put on that front thrust bearing on the stick assembly - 40 lbs for the up cable, 40 lbs for the down cable and another about 40 lbs for the spring. I could feel the friction in…</p>

I could feel the friction in the ailerons go up so I removed it. Back on the elevator bellcrank doesn't really add any extra load in the cable system. I also like how easy it is to fine tune the force. </p>

<p>Great idea, Thanks!</p>

<p>Test flight showed considerable improvement but trim still not zero. I added two more rubber bands and bingo. Cruise level with zero trim and full flaps, full up trim and throttle ides it files a hands off approach.</p>
