I have been waiting for these shocks for several months. I talked to Matt at Acme about this project around the time I pulled the engine for overhaul. He thought they could make a unit that would work much better. That is an understatement. I am thrilled to have a real shock absorber now. The oleo Maule uses look like something from the 1920's. The oleo I have been using was something that I took inspiration from AOSS. The were filled with ureathane disc segments stacked up and a die spring for the big hits. It worked much better then a Maule oleo. This Acme shock is nothing short of amazing in comparison. Great job Matt at Acme Aero Fab!
Re-watching all of your old videos!
Love my ACME Shocks. I have tweaked mine to my liking with Goose's (acme) help.
Yes, I loved them on my cub so I really wanted to get them on an airplane that I know would benefit from them as much or more.
Really loving your videos. Jumping over a 12” log! What a way to test a set of shocks. This really makes me want to move my plane over to the experimental category. Fortunately on the shock side the Stinson has a great system already. Keep showing the places you can go with a good Bush plane people need to keep seeing planes are fun,
Thank you
Great time as always. My favorite ending was the plane crash that stops just above the ground and bugs get out and days sorry folks we ran out of gas... Top shelf as always.
I'd love these on our Super Pacer!
It will be interesting to see how they last; your certainly the right guy to test them. Seems like it wouldn’t take much of a side load to buckle the small diameter rod.
It is a solid rod, that being said that is my biggest concern with any gear/shock set up.
@@mauleguy, Any update on how the shocks are holding up?
@@whee8e I had to send them back way to soft when I am loaded up. That was over a month ago and they were supposed to have a fix.
I really need them but I guess Acme is busy. Not sure when I will see the revision
@@mauleguy Thanks for the reply. I was hoping they were working great so I could follow suit. I look forward to an update when you get some more landings on them.
Some good ideas you’re basically kind of re-doing the art of bush plane shocks !! Your reinventing the wheel so to speak it’s people like you that makes it nice for people like us
I love the shots of your home strip. You test your STOL skills every time you leave the house and come home 😂. You have a beautiful place there! Nice set up with your Maule hanger……more challenges…..always testing yourself LOL!
Yes it does, yesterday was a no go. Way to much wind, just brought it home from my buddies strip this morning
@@mauleguy And that’s why you’re still flying😉
I just found out Acme Aero is almost complete in the production version of these shocks for Maule M5's. Can't wait
I've had two strips, both 400' long and 18' wide, and 14 to 16 degree slopes, one at 6150' and my current one at 5640', for over 30 years now in continuous use. Your home strip makes mine look like LAX!
:)). Believe me when I say I wished I had a big airstrip.
I often get 1 little bounce with my ACME's, kind of like some of what I see in your vid here., so I feel mine are a bit too stiff, or could use a touch more rebound control... but then I load up my plane heavy and they turn to butter. They really work best when I'm heavier... I believe that was the intention from ACME, and it all works out pretty well. They are very stable on hill sides and such too which some of the other offerings don't seem to do as well with. Sideloading the gear and compressing one seems the only easy way a guy could damage these shocks. I like having a spring inside in case there is a leak it won't sag down. Great company to work with. Matt took care of me. I'd love to upgrade my T3 tail to a stinger at some point. Looking forward to your review of the stinger. -Todd
Yes, I think you are totally correct. Same thing in the SuperCub, they work good light but loaded heavy even better.
Wow Kevin Quinn was right when he said you get some big kahunas LOL in the one video is Trent Palmer in him he picked up a couple big rocks he goes this is you!!! 😳😱😆
Ha LOL
Nice looking mod...Interesting to see a approved set with the extended gear!
More great info, Greg!
Glad you think so!
As always Greg, thank you for posting these videos. Your home strip really is crazy short.
yes it is, soon it will be 100 feet longer. Three trees coming down
Nice one Greg. It's always cool to get your perspective on techniques, mods, parts, etc. Curious when you go to Alaska how long does the trip take you? What kind of range does Bushwacker 2.0 have? I look forward to the videos of that!
It took me 2 days each way last year up and down the coast. I flew from Orcas Island to Sitka Alaska in one leg going up last year (9 hours of solid flying). I have 90 gallons of fuel when I travel.
Greg 350’ takes balls. Props to ya. Have you tried TK1 shocks or only acmes? I’ve only flown TK1s and this is the first impressive video I’ve seen of acmes. Nice work they look solid. I like the TK1s as they serve me well but lots of guys run the acme and are happy. Toe in like you have is like what I have on my cub. No issues. Lots of beaches and sidehills and I don’t have any issues. Tire wear isn’t a concern to me yet either. Was Lonnie running 2000lbs and acme?
Never ran the TK1, lots of people love them too.
You've been called out by Super701 using a smaller strip. When will we see you comment on this?
Cow dung glue🤣. You had my wife in stitches.... Yip your undercarriage is hanging a bit lower once you're airborne but that doesn't seem to be to much of a problem? Those tires can take a pounding but you can clearly see how the shocks delay the undercarriage from bouncing when you went over those ditches. They're clearly doing their job.. Looks like a great mod Greg. Love that strip of yours.
Thanks Vincent
Hope to see you out and about if you come to AK!!
Thanks
That setup works awesome. Now you can start landing in pumpkin patches, etc. hehe.. By the way the new font looks great!
Thanks Bob
I know it's not how it's done, but a trailing link is way more able to take a hit from the front (like a log or rock) than standard legs that swing out to the side like this. Sure this kind of gear is great at handling a drop, but that log was taken by the bushwheel more than the gear.
I've bent the rear tube on a conventional leg from hitting a rock, there's just not any give in the direction of the hit.
It is heavy and adds complexity, look at all Mike Patey went through on Draco to get the trailing link to work. Stock Wilga trailing link would not hold up to what you can through at it with 35" ABW. I know a guy that hit logs just to see what would fail and it was not the gear leg or bolts it was the lower longeron and it was an 18" log direct hit with 35" ABW and AOSS suspension. He started with smaller and worked his way up to the 18" log. His pocket book has more dollar signs in it than mine and he can afford to do this type of real world testing.
How well do those shocks hold up in the cold?
That strip is straight INSANE!💩
How did you build the courage to do the 1st landing there? Pretty sure i met you at Woodland when Bushwaker still had camo wings. I grew up around planes and always checking the skies for you as i live not far away. Dads strip is 6 miles east of yours and he is working on a Bearhawk if your interested in checking it out. Turned out to be long comment but we were wondering if you know anything about overgrown strip on southwest side of Mt St Helens?
Yeah I waited for a day that the wind was in my favor. Send me the GPS for your dad's place I will stop in. I am not sure what strip on St. Helens but if it is inside the monument area then it would be a no go. If outside probably could get away with it...
@@devonsarkinen3165 Thanks
I measured your airstrip, by the time you get your wheels on the ground, your lucky if you got 300' which isn't too bad in ideal conditions. Add in a little tail and the margin depreciates considerably.
Yes, it is not usable if conditions are not correct. I have a 2 different friends that have airstrips a few miles away that I use when it is to windy.
Очень Очень Хорошо! Спасибо! Удачи Вам)
Like others have said, the heavier you are, the better the ACMEs work. I am not on the latest gen yet, but all versions are good in my lightweight Cub. In my humble opinion, the Stinger is just as good of an improvement, better than the T3, and years ahead of a standard leaf spring. I'd love to see the fabrication that went into the top eye attach point? Your fab skills and overall design is always top notch.
Not much fabrication for the top eye... I just bored their cap hole from like .750 to .812 and press fit the eyeball bearing into it.
Would a J-3 be ok for some backcountry? Like riverbars and things? Light backcountry (kansas)
Sure, know the limits of your skills and the limits of the airplane. Leave some margin for error:))
@@mauleguy sweet thanks!
Great video. I wish you could do a video of hydrosorbs vs the acme aero shocks. On a cub of course.
Hydrosorb would loose that contest, can tell you that one without running a test. But it would be fun to see the difference on camera.
More like "Big Logs & Long Shocks Productions" now.
Good one!
Hey Greg great video, talked too Matt a few weeks ago about the shocks. Hoping to get a field approval at some point in the future. As you stated the Maule oleo is almost completely worthless. Safe flying.
Best of luck!
How much did this cost if you don’t mind me asking? I would like some real shocks on my maule.
Yeah, me too.
I don't actually know yet as they have been working with me on getting it right. I assume around the price of a Gen 4.... I think that is 3500
@@mauleguy Thx.
Hi. It fully does them justice. If pilots can't see this they don't understand bush shock systems that are effective and safe as grandma's apple pie.
Thanks Mike
Those cows have some glue in their poo - Greg Miller
yes they do :))
The point it's your work! What about like a carbon Fiber/kevlar mix maybe that would pop out from underneath the cowling after it tips a certain amount of degrees while landing? otherwise, its locked when flying then if you in some really are in some rough stuff? [always] lol! it powers on!? kinda like a ski that will stop tip-overs and prop strikes hell you or Mike could definitely devise something up? hell you may not want or need something like that? heck i dunno just throwing out some preventative caution into the wind! no pun Intended lol....
Hey Greg, I would be happy to come film for you like you said in the video. I’m out of Scappoose airport and would love to come flying with you.
Send me an email and will see if we can work something out. Thank you
What you your thoughts on TK1 Monster shocks?
Have not ever really tested them but lots of guys love them.
Does Lonnie still do instruction? The cub driver movies were great.
No not that I know of
#300 on the likes....! When do we see that same gear on a Pacer...?
I like your videos.
Thank you
You can tell the Cub is relly heavy by the way he’s throtteling it on in the way of f and on landings and the wheels flattening and wings swaying!
Well it is not a cub, it use to be a Maule kind of. I took a bunch of Maule parts and made an experimental airplane from them back in 2004. It is heavy compared to most Cubs for sure. It weighs 1359 empty, that is almost 300 pounds more then my Super Cub at 1079.
No I know that I was going by the second plane not your plane
I thought to be offical runway you need a wind sock.. 😜
He has the trees...lol.
LOL
Are you alone? Or do you have some friends flying with you at the time just curious none of my business really just in case something happened to you your doing some pretty amazing flying and landing and takeoff but WOW!!!!!!
Usually fly alone.
Yeah maybe trent palmer he’s an awesome videographer!? i’m not sure if you guys know each other I’m probably pretty sure you do you guys all hang out together don’t you why are you part of the flying Cowboys I think I’m pretty sure you are there’s so many of you I try to keep you organized LOL but I remember you a lot from all your landings and stuff
I am not part of the flying cowboys, if I lived closer maybe I would get to join:))
That toe in looks really extreme. It's really side loading the tires. The shocks work as advertised still.
Seriously, 350 foot runway...wow. It's a fact you won't get to many un-wanted visitors flying in there. There isn't much for tree branch clearance either.
Thank you,
Take care,
Be safe.
I assume you mean the camber of the tire not toe in. I am guessing working with Acme we can fix that partially, but that is also part of the 4.5" of travel you get from their shock. Like I said they engineered them for 1.25 at static and I had 1.650, so the numbers did not fully work out in the real world. Still even if that is the best they can do I will take it, never going back to 1920's technology. If you look at the Beringer shock/gear set up it really hangs down on a Super Cub. I don't see it as too much of a problem except maybe on off camber LZ's that is why I want to test it and see how it responds. Probably look at that this weekend.
I'm sure you've noticed it, but your left wheel looks somewhat out of true- seems to wobble a bit. Don't know if this is an issue or not.
No it really is not, these were blems that I bought so that could be why.
Elk turds are hard to remove too.
:))
I know you knownway more then me prob!! But cam you change your wheel angles?? it seems you’re putting a lot of undue stress sideways on your bearings and on your rods coming down like a 45° angle when you come down it’s like a 22° angle inward that seems to be too much but looking at the camera pictures if it was flatter coming down the wheels wouldn’t take so much of a sideways torsion! Strike!! Oh no doubt you def got a set!!! And your home runway lol not my level not even close if ever!!!! Love your attitide though!🦾🤙🏼🥶
Axle angle is fixed to the gear, it is a weldment. The side load you are seeing is minimal as the shock soaks up the bumps the tires take a lot of the stress too. We are still working out the amount of nitrogen to run in them but they are only tucked until you put a load on them. They have a piston and oil which is metered so that you don't get rebound. They are a huge improvement over anything I have ever had on this airplane but we are still tweaking to get it correct. If you grab the wing an rock the airplane it does not rock, as soon as you let go there is zero continuation.
Молодец!
17min video, 5 likes, and multiple comments 5min after posting. Hmm.. sus. lol. At least watch it first people!
Edit: after watching it the sketchiest part is driving into that garage with the engine on, I was looking at that little step ladder with dread.
Your negativity helps balance out this comment section. thanks👍🏽
Kenriko After repeated verification one develops trust and checks the like before watching.👍🏻
You know loony tunes is racist on the end ,but who cares !!!!
How so?
I second the how so. I am guessing that somewhere in the cartoons they were not sure how the ending is...
@@kelleyh2708 I was kidding, EVERYTHING is racist anymore. Like Dr. Suess.
