<p>Jan must have heeded your advice. I purchased and installed the steel bungee and it came with a powder coated spring. My only glitch was that the arms were too short. Viking met me at Sun n Fun and gave me new ones and had no problems installing. Because they showed me great customer service , I purchased the Viking 130 to be installed next month.</p>

<p>Dave, I responded in the thread where you asked about that. We've got too many threads going on the same subject. :-)</p>

<p>I love the solution as well but found the instructions lacking and the center threaded rod that is used to adjust the spring tension appears to wear easily (threaded portion) and was slightly undersized for nut being used. Another builder had the same issue and added a second nut just in case/for safety.</p>

<p>That told me all I needed to know. While I love the solution and hats off to Jan for coming up with it....it is doubtful I will purchase anything from him in the future.</p>

<p>Here is a link to the pics for my install... I powder coated the main parts and also had to drill out the top cap..</p>

Hi Stan<br />
I am also ELSA and have the repairman certificate.<br />
I was asking you if you did the install yourself and how high is your center rod above the aluminum top piece.

<p>Dave, you are correct; an SLSA cannot be modified without written approval from the manufacturer. Also, replacing the rubber bungee on an AMD 601XL or 650LS SLSA with anything other than a 1080HD would be illegal, and if - heaven forbid - there were an accident or incident and an investigation revealed the airplane had a bungee installed other than a 1080HD, whomever replaced it last would probably have some serious explaining to do. It's just not worth the risk.</p>

<p>After studying my options, the only thing that made any sense to me was changing the certification to experimental, taking the 16 hour LSA Repairman - Inspection course, and getting the FAA repairman - inspection certificate.</p>
<p>I'll be the first to admit this may not be the answer for everyone.</p>

Sorry Robert,<br />
You cannot legally do any modification to a SLSA without factory approval. AMD is out of business, so that's impossible.<br />
Zenith even recommends switching over to ELSA. I don't think a ADS B install is legal without factory approval.<br />
I sent you a message about your bungee, you need a 1080HD bungee. The one you bought should not be used.<br />

I have a 2008 AMD 650 LS which needs a bungee replacement now. I'm glad you mentioned this problem with AMD built Zodiacs. I have another question. I need to replace my Bungie right now and my mechanic asked me to find out if it is legal to do the Viking modification on a factory built aircraft which has not been turned into an experimental?<br />
<br />
I'm not interested in being a repairman or taking my airplane experimental.
