J430 Electric trim

Unread post by Pepler » Thu Jan 28, 2016 11:14 pm

Hi everyone,

Need some advise please from the "old hands"

Recently purchased a J430 (FBI) now based at FAFK
Has anyone done a successful mod / conversion / fitment of electric trim on a J430. (post 2009 model)
Some other threads suggest in might create problem with autopilot's elevator servo.
Idea is to fit additional servo to move trim lever via two up & down buttons on the pistol grip and install new flap switch on panel.

Any advise will be much appreciated
Thank you

#-o Eishh, this sounds like a job for the factory! Marius once warned against fiddling with the pistol grip, cost him a new one :shock:

No old hand either :oops: However my AP shows where it want you to trim manually. My 430 is setup in such a way that with my fat ass in it I need full forward trim in any how. :? :oops: Sorry double transmission.......answered on the unmentionable part of avcom. :wink:

Thank you gentleman for the advise so far.
As far as I know there is no "kit" for this that the factory can fit, but I will contact Len to see what he says.
Think it would be great to have trim on the pistol grip to avoid leaning over once's own boeppens on takeoff :mrgreen:

Got this picture of a setup that seems simple enough but I would rather ask advice 1st.
Anyone out there that has electric trim ?

Thank you

My 430 weighs 379 kg.(with a AP) :D I once asked Len why 430's became so heavy. Typical Len he gave it some thought and then replied. "You guy's want all sorts of toy's and many coats of paint"......he did not say it but I got the impression his thoughts was that this was never the design philosophy of a Jabbi. :idea: I have flown with a jabbi plastered with nice to have's....even a "storm scope"....it has had all the newest engine upgrades....in spite of that it feels like a tank and takes 200m more than mine to take off. :?

I don't fly a Jabi plane, just a Rans with a Jabi engine. The trim motor in your document is quite heavy. In fact, I use that type of actuator for electric flaps. For trim this is way too heavy.

As electric trim I use a small Ray Allen servo inside the elevator which moves a trim tab up and down. Very light and effective. Not sure if that can be done in a Jabi though.

Hi Dawid, hope you enjoy your plane. Leon (LegAir) suggested to me to fabricate an extention to the manual trim lever, making it easier to reach and operate. Please call him and discuss this option, I have seen it in other Jabi's.

Contact Checkride here on Avcom.

He did a very neat and lightweight electric trim on his aerie, I was impresses with how it operated when I last flew it. 8)

Maree Matthee's plane came with a factory fitted electric trim, the plane was originally build for a pilot with limited use of his one hand. So it could be done either way.

Baie Dankie Matie & ZB vir die raad.

Matie dis soos 'n nuwe girlfiend, kan nie genoeg kry nie :lol: Almal hier wat FBI sien praat net oor die "great looking plane"

Terugvoer van fabriek is dat hulle dit nie elect opsit nie en daar nie 'n kit / modifikasie beskikbaar is nie.
Geweet ek gaan regkom hier want dit lyk my die Jabi gemeenskap is ook al redelik selfonderhoudend.

Sal met Leon en Checkride praat

Groete

Sorry, but why would you like electric trim to start with?

Open up the cover on the botom below you rudder. That houses the trim mechanism. Take a stool sit down and study the ingenious design of that mechanism. For the lack of better termalogica the best I can describe it is a floating neutral trim. Works like a charm and is very uncomplicated!

Ask that same question when your RV is finished :lol: :lol:

It controls the whole elevator, not very efficient.
Autopilot has issues----not anymore
With the electric trim and a balance elevators , plus those stupid trim tabs removed-less drag, better authority, lighter feel, weight reduction, Autopilot happy, Pilot happy.... :lol: :lol: To name a few, Im sure my son would have more to say

Try putting two people in the back of your 430. Not enough trim to fly straight and level.

:shock: "Those stupid trim tabs" might one day save your life if you break a elevator cable. 8-[ :idea:
