Does the Van's aileron trim work? Do most planes have it installed?Â  



My plane isn't flying yet - I hope to have 1st flight in a few weeks- and I was just about to install it.Â  If the consensus is that it isn't worth it, I will forgo installation.

Tom,



If you are referring to the spring loaded aileron trim that installs under and between the seats my answer is a resounding yes, it works great and I use it constantly.  I can't speak for how many have it installed but I can highly recommend that you do install it.



It took me a few flight hours to get the tension set just right so that it's fairly easy to adjust and doesn't creep,  but I haven't had to touch the tension adjustment for over four years and more than 600 hours

I have a combination of Van's manual trim with a Ray Allen servo mounted in my left wing.  It actuates directly on the aileron bellcrank and works very well.



Accessible for maintenance through the stock panel.



Keep plugging....

It works well and is very much worth it.

Tom, you will use this a lot.  My RV-7 needs  aileron trim depending on if I am solo or with a co-pilot and also as you burn  fuel from side to side.

Hi Tom,

  

 I installed my Van's aileron trim AFTER my first few flights  to first deal with the possible heavy wing and avoid the trim system from  confusing that. And, after dealing with the permanent rudder trim. Once those  adjustments were made, I installed the aileron trim. It is simple and worked  well for me. It mainly served to adjust for fuel burn unbalance. By alternating  tanks periodically, I kept that balance pretty well but used the aileron trim  when needed for finer tuning. I consider it was very worthwhile.

  

 Good luck.

Sarg,

 I bought my 4 flying. When I saw the spring loaded trim, I kinda giggled..........then I tried it...WOW. Much like the rest of Van's ingenious inventions........this one is great!

 Very simple, very effective.

Tom:I installed electric aileron trim in my RV-7A.  Yes - it does work and yes I would install it again.  I find it useful trimming for imbalances due to differences in fuel quantities.  On the one occasion when I've used my tip tanks I burned off the four gallons in the left tip tank, and with four gallons in the right tip tank there was a noticeable tendency for the right wing to drop (4 gals X 6 lbs = 24 lbs). It trimmed out easily.  This is not so much of an issue when you're using only the main tanks.

Hi Tom



I installed aileron trims on both my RV-6 as well as my RV-7.  They

definetely are a must, however Van's changed the orientation of the

installation from the -6 to the -7 and I found the position, orientation

(lever points to which wing you want lowered)  and feel to the -6 was far

better than what is on the plans for the -7.  The good news is that it is

easy to change - just invert it and move it higher up on the rib, taking

care to check for freedom of movement, both for controls and trim. 

Chances are if you are building the -6 the drawings will still be the old

ones but if you are only ordering it now, I suppose you will be getting

the new drawings.

Thanks for all the responses on this.Â  Looks like the aileron trim is one of the things every one agrees on.Â  I'll start installing it tonight.

Well not everyone.Â  I was going to post but it looked like I was to be the odd man out.Â  If I had it to do again, I wouldnâ€™t bother since I never use it and see no point it is just complexity in that tight area I donâ€™t need.Â  Maybe I am a sloppy flier but my plane seem to be level regardless.Â  Of course I manage my fuel beginning from the left tank and then switch every 30 minutes.Â  I canâ€™t tell any difference with two in the plane or alone.Â  Sounds like a best bet to install for you though since so many others agree it is worth it.  

   

I just thought I would throw that out cause I am sure it will start some conversation on here.Â  I hold the control stick between two fingers near my legs once at a safe altitude and find very fine control with light input that way.Â  Maybe I just correct for it; donâ€™t know.

I agree with you Tim. I have it but rarely use it  because of usually using the AP when flying in a straight line to a  destination.

Tom,

 I have close to 2000 hours on my RV8 over the last  8  plus years.  Shortly after completing my RV8, I realized that a  trim system would be a good addition.  Primarily because I noticed that  after  using 3 or 4 gallons of fuel off of one side, I noticed that the  wing tanks became lighter and required aeleron input or trim.  On short  flights, it did not  make much difference.  However, on longer flights  it became tiresome holding left or right stick to stay level.  I looked  at  vans trim system and realized it would work ok, however, it would  increase stick load right of left depending on fuel usage. As a result, I  designed an aeleron/elevator trim system using  miniture trim tab built  into the outboard edge of the  aeleron( approx 1 1/2" x 6") driven by a  miniture MAC trim motor.  This required a very minor  change in  aeleron balance   (it probably would have been ok without  it

 but, I felt more comfortable because I race my  airplane,,and at speeds of 240 mph,I had some concern.

 I also used a similar trim syster in the  elevator.  Call for info.

I am late in seeing this thread, so I may be  repeating whats already  been said. I fabricated and installed the vans  aleron trim unit shortly after I aquired my 6A. It is a simple concepts, no  motors to fail, and it works very well. Just move the lever a little left or  roight to keep balance as fuel is burned off. Charlie

After more than 1 C000 of Cross Country Flying and more than 2 C241 flying hours in my RV C I have to say that that Van's Manual Aileron Trim works great.  I would not think of making a cross-country flight without it.



I does make up for small changes in bank that occur with fuel burn and loading.



I can trim so that I can take my hand off the stick for 1-minute so that I can fold C unfold maps C or do other cockpit tasks that one may need to do without using my autopilot.



Gene Hudson in his book "Precision Attitude Instrument Flying" recommends keeping the aircraft in trim so that the pilot can concentrate on other flying tasks so that you do not have to hand fly the airplane.



I keep my aircraft in trim so that it can fly hands off most of the time.  You can fly the aircraft without aileron trim but the aileron trim allows one to fly the airplane hands off.



Yes an autopilot wing leveler can do some of the work but there is no substitute for a proper rigged aircraft with elevator and aileron trim.  It reduces the pilot work load a lot on cross-country flights.

A high percentage of the RV's being built now have electronic trim on both ailerons and elevator.  You put a hat switch on the stick and your done.  When I fly, trimming is automatic -- I don't even think about it and my plane flys "hands off " all the time.



Another example of how well Van's designs work.

Really depends on your definition of 'reasonable'.  My approach involves 

using model airplane servo's (they're small), a single chip computer and 

a program I wrote ..... because I can.  I haven't decided whether to 

mount the aileron servo in the aileron (changes the mass balance point) 

or on a bracket on the wing to position the servo arm at the rotation 

axis of the aileron.  Not there yet.  Rudder trim servo will be mounted 

in the rudder.  The trim tab will be a section of hinge on the trailing 

edge.



If anyone has the 'hinge type trim' installed, how long is the hinge???

Yes—pretty sure.  The Vans aileron trim, manual or electric, is apparently in the fuselage, and works by applying more or less force to springs on the control stick.  There is nothing in the wing with respect to the aileron trim.  While I haven’t got that far into my build, I imagine that going to electric from manual is not involved, or even retrofitting the aileron trim into an already-built airplane.
