I just got back from a trip and saw your question about the trim travel. I
measured mine today and it is very close to your measurement. I have 20.3
up trim (down movement of the trim tab) and 24.8 down trim (up movement of
the trim tab) for a total of 45.3. As I recall from the last RV that I
flew you use very little of the trim tab to adjust for approach speed and
curse. I see no method of getting more travel without changing the trim
servo. Maybe someone else has a method to get more travel from the servo.
good luck

I bent the rod a few degrees and that worked very well. It not only gave me

I now have another question: I measure a trim control of 20.6 degrees up
trim max. and 23.2 degrees down trim max. Van's figures, on section 15:
Flight Controls, call for Maximum up/down of 25-35 degrees. That implies to
me that a minimum travel of 50 degrees is necessary. I'm getting 43.8
degrees, so there's no way to meet these numbers. It's all that the motor
actuator will give.
Any comments as to what's going on?

Dear Rafael,
I had the same problem, till a more experienced builder told me to put a
bend in the threaded rod.
It will lift it just slightly and should give you a little more breathing
room.
Hope that works for you. Sorry I don't have a photo close by to send.

Hi folks!
I would appreciate some help. I'm trying to rig up the electric trim and
find that I need to trim away quite a bit of metal to eliminate interference
for the full down trim.
I followed Van's instructions regarding the positioning of the trim motor
mount. As you can see from the pictures, though still within the opening
footprint,
the actuating rod turned out pretty close to the inboard edge. (I thought
about centering the mounts at the time, but decided to trust the plans.)
After installing the trim system, there is a slight miss-alignment, but
nothing that would cause stress in the system. I made some marks on the
max, min, and half-way travel of the actuating rod. I then adjusted the
length for no trim at the half-way point.
What worries me most is the amount of metal I have to file out to prevent
the actuating rod from contacting the elevator under max down trim. As you
can see, I've already removed quite a bit of Aluminum. I hesitate to trim
further without some reassurance.
Van's builder's assistance is closed for the weekend, so I thought I would
seek y'alls' help (I recently moved to Aiken, SC, and I'm learning the local
grammar ;))
Thanks and best regards,
Rafael

He's built several engines for people such as Mark Chamberlain and
Darwin Barrie (Phoenix area). I spoke with him a few months back after
his EAA presentation about the engines. I was on the fence until I spoke
with him about it. Now I'm just waiting (actually still building and
saving) for ECi to come out with a stroked IO-360! Yeah baby!

Subject: | ECI Titan engines |
Hello Mark,
I purchased the ECI Titan kit (188 HP at 2700 RPMs)...basic O-360-B1A
(hollow crank). The short of it... I have not started the engine as of yet
but am happy with the build. I asked John Sjaardema (Excel Air in
Rensselaer, IN at the airport), www.excelairservices.com) my builder to take
on the engine build...customer assisted (a plug for John). I basically
built the engine myself with help from John and his certified A&Ps (work
space, knowledge, parts, tools, etc.). Spent about 2 weeks part time
building the engine and everything looked good...the entire kit was within
specs (a few exceptions), and John is very particular about clearances and
so forth. I probably spent 2 days with the micrometers.
Exceptions: there were 3 tapped holes in the case that were not all of the
way thru and would not accept a full-length bolt; but we modified the bolts
and were acceptable to John. Also, 3 exhaust valve rocker arms were not
within the dry-tappet specs in the Lycoming manuals (John's specs...minimum
0.030 clearance) but ECI made the fixes at their facility--ECI sent them
back, I installed them and were perfect (0.035). John and I were happy with
the build. John also painted the engine. I also replaced the cork gaskets
with a better quality gasket for the valve covers--the cork material tends
to leak. I also replaced the adjustable oil pressure part with a manual one
(adjustable with washers)...the adjustable part tends to leak also.
My engine situation: Precision Fuel Injection (reman Bendix-style servo--no
fuel tank return requirements), vertical induction (I like the snorkel
look...more distinctive and more effective air flow), fixed pitch prop from
Sensenich and of course the Titan cylinders. The case is mfg by ECI and
most of the parts but the crankshaft and camshaft are Lycoming products...I
believe (experimental); not sure on that. I also purchased a new SkyTech
starter for the engine and the FWF kit from Van's which is mostly done. I
purchased the kit, Slick mags (dual coupling) and a few other parts (fuel
pump) from A.E.R.O., Inc. Their pricing was very competitive and they sold
the new mags basically at their cost (www.aeroinstock.com, Grant City, IL)
who is also a builder. POC is Jesse Robinson. Sorry for the plugs.
Hope to fireup the engine next month.
