C5Engineer added a topic in Avid fox flyers pics and vids
An after work day of playingI went out today to do some more playing after installing my VG's on the tail. I'm sold on this mod. It helped alot with the slow speed handling. I spent over an hour flying around in terrain low and slow. My approaches are easily 5mph slower which makes a huge difference when trying to get in short. I set her down a couple times today and also flew around for a while with the doors open.
Love flying with the doors open

Bryce good information!! I know on the big jets were directed to load our cargo/fuel in a manner which gives us the most aft CG within limits. This is for fuel savings. An airplane flies more efficient with an aft cg but it's also LESS STABLE.

Cal Neva Rockcrawling finalsI took my 22mos daughter up on Donner Summit in the Sierras on Saturday to watch the Cal Neva Rockcrawling finals. These guys are professional drivers with heavy sponsorship and a blast to watch. The pics don't do this stunning natural terrain justice. These guys drive on stuff you can't even walk up. It's impressive to watch the coordination between the driver and spotter. On to the pics.
I took this pic to Thank Davez Offroad. I got my free ticket from him. He has done work to my rig in the past and is known as the Toyota Guru of California.

Looks on it's side but this was really some awesome driving/spotting and some collection of bonus points

Leni, you mentioned the vg's on your tail did more good than the ones on the wing. Where is your cg? My reason for asking is that i am also installing vgs from cci, which are about the same as stol speeeds. Art Biaconne, he is cci, has been helping with all of this. My cg started at about 14.5inches. I added the vgs to the horizontal and immediately noticed a difference in pitch authority. However, i still was unable to get a full stall, which Art said i need to do before adding them to my wings. Additionally, my minimum airspeed was roughly still the same, though i'm thinking it's position error at this point. I checked to make sure i was getting full up elevator of 30 degrees (i think), but i only had 25, so i fixed that, and still no full stall! So borrowing from my r/c experience, i added 5 pounds to the handles in front oh the horizontal stab. This provided more pitch authority, but still no full stall. So i added another 5# for a total of 10#. I get just barely a break, maybe a 5-10 foot stall/drop before i'm flying again. So i'm going to add 5# more to get more of a stall break that's more cessna like. Then i'm going to add vgs to the wing. Now here's the kicker, my cruise speed, same power setting/load etc, has gone from 85 mph indicated to 100 mph indicated! Which begs the question, whats the vne on a mkiv? Bryce

Thanks you guys. That's ahellofagood idea adding stiffeners/gusssets to the longerons. Also preflighting the gear truss and gear leg makes alotofgood sense! Bryce

Bandit added a post in a topic Tail wheel to trigear gear.
Don't give up yet Russ. Go to the thread I started on the Avids new Cabane spring gear. Read the last post on my flight Saturday evening, it is hard to believe, but true. The wide gear really seems to tame them down, and I have just about no brakes. I can't even hold my airplane at 4000rpm for run up. Once the airplane is done flying get that stick pulled back into your crotch and keep it there until your rollout is done. That tailwheel has to be held on the runway. If you need hard brakes to help yourself out on rollout you are to far behind the airplane already. I agree with AK make sure you check your tailwheel. My Maule was unlocking on rollout at first. Ground looped 3 or 4 times before I figured it out. If you have a Maule make sure you set it so it does not brake loose, or switch to the Matco. When you are flying in normal conditions you do not need a full swivel tailwheel anyway. I don't know if I ever broke mine loose.

I'll make it X3.You can do so much more with a tail dragger avid than if you tri it out.there is lots of stuff you can do to your plane to get better control of it...alter the tail wheel pivot bolt geometry;get your brakes up to snuff so you can directional control mostly with differential brake and leave the tail wheel out of the picture as much as possible on rollout.

X2 Dont give up on a damn good plane or make alot of extra work for yourself. Could be something as simple as tail wheel geometry (kicked my ass once before) or a tail wheel that needs to be rebuild so it wont unlock so easy. Or Or Or Or...

Russ - Stop. Take a deep breath. How can we help you fix the problem without needing to do major surgery like a nose dragger conversion?
Before you jump headlong into a major modification like this, what happened? Tell us the story.
Do you have a simple toe-in/toe-out problem that's making the roll out unstable?
Do you have a brake issue that makes them too sensitive or not sensitive enough?
Do you have enough training with an instructor to give you the confidence to control the plane?
Would the wider bush-gear work better to help your stability issues?
These planes are not uncontrollable widow-makers. Lets help you fix the problem not mask it...

Russ. added a topic in Avid Flyer General Hangar
Tail wheel to trigear gear.Hi all,
After a not so nice landing this past week, I have decided to convert to trigear as I repair the damaged parts.
N844RS flys beautiful and takeoffs are o.k. The landings are crap. I have been told the main gear swapped left to right side will work. I need the weldment and nose gear setup. Any advice or help will be appreciated.
Russ. former TD pilot.

Bandit added a post in a topic Cabane gear installed
Joey, Im going back over Sunday, I'll get you the measurements. Flew tonight again. I did something with my Avid that I had never done before the gear change. I started taxing from one end of the runway to the other and never once put my feet on the rudder pedals. My tach read 3000rpm, airspeed indicated about 32 mph, I could get directional control with the flaperons, left input turned right, right input turned left. I did this for 3600', with no wind conditions.
The wheel base with my tundra tires is 82.5". The clearance with my IVO 3 bladed 66" prop is around 19".

akflyer added a post in a topic Airdale Wide Gear
Once again, Doug offers GREAT advise!
I put stiffer plates of each side of my fuse from the firewall to the cluster behind the strut attach point. My fuse was a little bent in this area so after straightening, I added the plates on each side to keep this from happening again. I figured 2 pounds worth of plates was alot better than a gear leg shoved up my ass out in the sticks somewhere. Could be just me, but I thought it was a good trade off
It would be very easy to add the ply gussets in this area also on a completed and covered flying ariframe. A little time spent with card board templates, 30 minutes transfering them and cutting them out of ply, and about an hour to glue them all in and you have a substatially tougher gear box area! Dont forget to let the glue cure for 24 hrs!

That should show you the plates I did on the sides out of 4130 plate.

Bryce,
I have the Airdale W.I.B. on my Avid+ as well. It isn't flying yet so I can't help much there, but I do have some thoughts on this topic.
First, I agree the seat truss stiffener mod is mandatory if you're going to use either of the bungee gear options (Avid oem or Airdale W.I.B.). It stands to reason that the longer legs and wider track will increase the force imparted on the seat truss when bottoming out the bungees or safety cables.
Secondly, when using any of the wider bungee or spring gear options, I would strongly recommend doing the same mod on the side seat trusses above the attach brackets as well. With any increase in gear width, the vertical force endured in those less-than-perfect pancake or hard drop style landings will surely be increased at the side longerons as well.
Third, regardless of which gear you use, do not underestimate the increased forces imparted on the longer gear legs horizontally. Grove proponents push the spring gear in spite of its weight penalty, in part, because it eliminates the possibility of bending the seat truss. But it attaches to the fuselage in such a way that actually increases the potential for damage to the side longerons in the attach bracket area, IMHO.
Should you doubt that stiffeners in the side truss are a good idea, I offer a couple pics of my KF-III showing what happens when you drop a Grove gear leg into a drainage ditch at about 50mph. I've often wondered what would have happened with reinforced side trusses and the W.I.B. gear. Maybe just sheared the leg or ripped the attach brackets off, dunno, but either might have been less expensive than the twisted fuse I ended up with.

Some of both. When I posted the pics up on the Kitfox list, there were several guys that chimed in and said they had the same thing happen to them.
My Brothers KF had only been flown off grass strips prior to landing on one gravel strip that folded it up. It had been cracked for quite awhile.
LOTS of guys have MANY MANY hundreds and thousands of hours on the stock gear with no issues so this is not a panic item, just something to be aware of, and take a look at on a routine basis. There are too many that have failed to not say it warrants looking at and putting on your checklist, but damn sure not enough to say toss the gear and go grove or the spring gear (as of yet, the spring gear is really un-proven in the back country getting the shit beat out of it but I am sure that will change VERY soon!)

Congrats!!! It only get's better from there. If you end up having to use a rudder trim tab 1/2" 3M double sided tape from the hardware store and a scrap piece of aluminum work's great.

Leni,
When those welds broke, had ya'll been landing on gravel bars or other rough fields or was it just from normal use? Thanks, Bryce

Skyraider FlightTook the Skyraider up out of the pattern Sunday for the first time.I had to keep a little left rudder in it the whole time,a buddy is going to help me with the strut rod end and try it again.It got really windy so could only go up for one flight.I flew for 45 minutes and the temp stay at 155 to 160. EGT at 5500 RPM was 1080 on one and around 1070 on two.The door flew open twice and the wind came up higher than expected,the landing was a little hairy but made it home.Ive decided not to fly in the wind until I get a little more time on it.All in al I think it will be a fun little machine. Randy
