Hi Everyone,



It seems as though I have been scooped in the marketplace!!



With the introduction of the Matco adjustable axle my product offering 

has effectively been run outta town! There is little chance of me being 

able to compete with a product being offered by the company with whom 

the problem originated. This is just how things go sometimes.



I would like to inform those who had contacted Cleaveland Tools to place 

a pre-order that I have canceled the product offering in fairness to 

Mike at Cleaveland Tools even though they had ordered product already. I 

would hate to have that product sit on their shelves with no interest in 

them.



To those who had the confidence to pre-order my adjustable pre-load axle 

spacers, Thank You. It is always gratifying to have the confidence of 

your peers.



I look forward to offering other accessories and parts to the kit 

builder and kit manufacturer alike.



Regards,



Dave

I think I have it in a box at home and look forward to testing your diagnostic and problem solving ability. Thank you for spending the time in solving a problem that seems as though it should have been previously thought out. 

  

 Not much money in it for you C but I have something that most other don't have on their 10 so that is cool as long as it works.

  

 Thanks C

In all fairness to Matco, it should be noted that Matco just

made the wheels and Vans picked them for the RV-10.  Van's

designed the axle and spacers, and Van's chose to make them

the way they did...choosing not to make them fit the bearing

taper, choosing not to size the inside of the spacers for

the rubber seal....all of that.  So the design flaws aren't

Matco's fault.  They didn't even SEE an RV-10 application until

they worked with Scott to try to find out what they could do

to stop getting complaints about the design...so they worked

with him to come up with a better design for ALL of the

RV nosewheel kits.  They HAD to come up with something, so that

their own reputation doesn't suffer from the bad design of

our original kits.  This isn't a big slam on Van's, either.

They try their best to make things cheap for the builder.

The problem comes in that many people, especially people

building the higher-priced RV-10 model, aren't happy with

some of the cost compromises, and expect more.  That's how

things like the axle extensions, this nosewheel fix, and

heck, all of those Rivetmaster and iflyrv10 parts came to

be....they're all improvements on the original design that

many builders think should have been done better initially.

That trim nut that goes on the trim cable access plate is

a HUGE one.....the original welded stuff is an accident waiting

to happen.  If I hadn't silver-soldered mine up tough, I'd

never have felt good about it.  Now you can buy a nice

replacement that is much better than the original.  The

sad thing is, all of these improvements have never made it

into the RV-10 "standard package"...which would have made

it easier on the builder by maybe upping the kit price

by a few dollars, but providing you with the best in parts

right off the bat...saving you shipping, time, hassle, and

worry.  With products like the Axle extensions, there are

going to be many people that don't hear about these

parts, and they'll have things like smashed wheel fairings

because of it.



Anyway, Matco wasn't the problem with the original design,

but they're part of the solution...and I think the pricing

is indicative of them trying to ensure that their company

name doesn't suffer because of an over-zealous cost-saving

attitude of our kit supplier.  In the end, it's just a good

thing that there are becoming some good "standard fixes"

for the handful of shortcomings that we've found.

You know I remember when all the aftermarket things started to come about and what a great thing the people who made them have contributed, the trim nuts Tim is talking about were a joke!! Mine broke off just trying to rivet them to the plates...Has that changed? If not builder beware because it is a BIG safety of flight issue. I think I've purchased almost all of the machined replacements from rivethead when they first came out, iflyrv10 has great stuff too although he wasn't around when I needed the parts. I mounted the door pin receivers this past weekend and I have to tell you the door just sucks in and locks...I was very impressed how they work. One thing I had to do is open the receivers just a little, I used a sanding drum on a dremel. The machine fit of the pins/rods was way too close to work with the movement of the door as the pins engaged. A quick pass inside with the sanding drum proved enough to allow them to slide in easily but still no movement once engaged. My pins protrude at least a half inch past the vertical aluminum posts both fore and aft, I know someone was asking if that was happening. One tip I can pass on to mark the holes for the receivers, chop off the end of two AN-3 bolts and sharpen one side to a point. Screw them in to receiver pointy side out. Put some masking tape where the holes will be, Slide a piece of the door pin tubing into the 7/16 hole drilled for the pins then slide the receiver on pressing the points into the masking tape. The points will leave a nice dent to drill your bolt holes. Thanks Chris H. for the idea!! Worked like a champ.

Just a small addition - the iflyrv10 receivers are done a bit

differently.  Instead of a tapped hole that you but a bolt/screw in from

the back, they are drilled through and have a recess on the exposed

face.  He supplies stainless #10 capscrews for installation and the

heads sit inside the recess.  Much easier to install.

I just ordered mine from MATCO (sorry Dave).  Must be popular because they are already backordered about 2 weeks.  They are still offering the sale price.  I bought the balance weights too and will balance the mains as well as the nose wheel.   My thanks to y'all that have paved the way for the rest of us.



On some aircraft it is a good idea to balance the wheel pants too in order to reduce shimmy.  Does anyone think this is necessary?

Yeah, when they called about my order they asked if I needed

the weights.  I already had some, but I highly recommend a

balance.

Now, I can't say it made a difference or not, because mine were

always like this, but,  I taped ziplocs of lead shot to the nose

of my wheel fairings, and got them balanced out roughly.  Then

I epoxied the lead shot into the nose of the fairings.  I did

it because I had heard that balancing them was a good idea,

but it wasn't a common subject to read about...but I just did

it.  I can't say it made a difference because I didn't ever

fly without them that way, as far as I know.  But, it probably

can't hurt.  I would think that if there were a  big imbalance

it would encourage a rocking motion with the bumps.

I have a 2 week back order as well.

I'll balance all the heels, statically as I have found that has worked fine 

with my bike tires, I know Scott mentioned that Dynamically they were out of 

balance even after doing his statically so I may pursue it a little further.

I wont deal with the pants since I can't image they would cause a problem 

unless they are way off aerodynamically

Tim,

What do you use for the balancing point of the wheel pants? The axle  

location?



Thanks,

Yeah, I balanced them around the axle hole area.  Not sure

if it's perfect, but they were very tailheavy otherwise,

and the more weight that's out there swinging, the more

up and down they'll go.  Even just from a wear perspective

it just seems like a good thing for longevity to keep

them somewhat neutral.

I have a feeling they hadn't had a full production run yet as I ordered mine right after reading Scott's post and I was also backordered.



  As to the wheel pants, I've read in the past where people have balanced their pants fore and aft and saw a large reduction in shaking of the mains on other aircraft.  It's fairly straightforward and doesn't add much weight so I'll probably be doing it.

We balanced the wheel pants as a precaution. Each side took almost 8

ounces to neutralize the pants. I hated adding the weight but figured it

was batter than extra vibration and gives me an excuse when my -10 comes

in extra heavy...

I am confused as to the best way to balance (either dynamic or static)

the wheels. I read how Scott got them spinning but one you see it out of

balance how does one know where to place the weight to counteract the

imbalance? I have no idea how one does static balancing. Any hints would

be appreciated.

Just a guess but I bet he spun them, but then looked for where

they rolled low, just like doing a normal motorcycle balance.

Then probably spun them up again and checked again.  Since

he said that the weights were all on one side, it can't

really DO the balance much better than using precision

bearings...the difference is that he spun them up to look

for how bad it shook.  That's my guess.  Otherwise you'd

need some precision sensors and all that stuff.



FWIW, I saw Harbor Freight had a sale on their motorcycle

balancer, for $39, and included the precision bearing

roller shaft stuff, along with a nice stand. Seemed like

if the quality was good, it would be a good way to go.



I only know my balancer, and I can tell you that if there

is any weight that is off, that one is sensitive enough to

show you.  But, side-to-side distribution wouldn't be

possible to determine.

I believe my issue with the static balance on the mains was that I put all the weight on once side of the wheel. 

You can imagine that weight wanting to be thrown off as an imbalance or vibration starts. 

I also used the balancer that Tim shows in his write-up. http://www.myrv10.com/N104CD/maintenance/20080503/index.html

At first they were very out of balance statically and took close to 2.5 - 3.0 oz to bet them balance statically. 

Now when I spun them up I could not believe how bad they were.  Part of my problem I feel are my Goodyear Flight Custom III tires. 

They seem to be heavier and have more tread and the place where you put the weights on these wheels are very close to the center (low moment).  



To answer how I balance them.  I know where I had the weights before and just started taking weights off as I spun them up.  

My buffer was running at 3000 RPM (6" disc), so I had my wheels roughly at 54 mph.  It was really cool that I could still pick up the harmonic I get around 30 mph. 

Through trial and error I got them very close.  I need to revisit this again and I will take some video to show you what mine do. 

By statically balancing my front wheel and placing weights on each side it worked out perfect.  I feel I just need to go back and statically balance my mains by evenly distributing the weight.  

I may pull the brake off and put the weight on the inside to get it even closer.  

 

I am going to see how my vibration is before balancing the wheel pants.

For those who asked: Yes, the more recent RV-10 kits do come with the upgraded nut for the trim cable. Basically, a larger welded area between the nut and the stainless plate. I thought Van's even issued a SB on this?

I have the same balancer as you and Tim but, rather surprisingly, I couldn’t find really any point of imbalance on my nose wheel but I still have to mount the mains.  I like the buffer trick and will spin mine up and see if I get a resonance out of it.

 My buffer was running at 3000 RPM (6" disc), so I had my wheels roughly at 54 mph.  It was really cool that I could still pick up the harmonic I get around 30 mph. 

 Through trial and error I got them very close.  I need to revisit this again and I will take some video to show you what mine do. 

 By statically balancing my front wheel and placing weights on each side it worked out perfect.  I feel I just need to go back and statically balance my mains by evenly distributing the weight.  

 I may pull the brake off and put the weight on the inside to get it even closer.      

 

 I am going to see how my vibration is before balancing the wheel pants.

They did.  You're supposed to inspect and replace the part at your cost.

Tim, didn't you take your wheels to be dynamically balanced at a cycle  

shop (or somewhere) at one point? Or were you just wondering if that  

made sense?

Maybe I'm just getting forgetful...

 really DO the balance much better than using precision

 bearings...the difference is that he spun them up to look

 for how bad it shook.  That's my guess.  Otherwise you'd

 need some precision sensors and all that stuff.

 FWIW, I saw Harbor Freight had a sale on their motorcycle

 balancer, for $39, and included the precision bearing

 roller shaft stuff, along with a nice stand. Seemed like

 if the quality was good, it would be a good way to go.

 I only know my balancer, and I can tell you that if there

 is any weight that is off, that one is sensitive enough to

 show you.  But, side-to-side distribution wouldn't be

 possible to determine.

Nope, I did them myself, but on a motorcycle balancer.
