RC Plane Suspension: the results are shocking

[@suncitybooks5542]

It is called trailing link suspension the same as the air cooled VWs one of the reasons they were popular for beach buggys.

[@bulwinkle]

You can see it on some motorcycles in both trailing and leading link designs?

[@MajDuty]

The trailing link suspension we have now is not oil dampened and that's what he is showing

[@robieosborne7369]

[@alancotton7766]

[@steamguy101]

It's called a "trailing link suspension". The US Navy loves them (see an FA-18 carrier landing) and it's used on many private aircraft such as the Wilga.

[@SammSheperd]

steamguy101 Oh cool thanks!

[@Renatodonadio]

It is also used in the Vespa front suspension, after WW2, Piaggio converted "pony" starter motors and gears from planes they made as an aircraft factory, to the front wheel and the engine of the Vespa ;-D

[@sammvoyager]

steamguy101 - -Yep. My Boeing Engineer/Lead mentioned the US Navy & maker of the F18 wound up doing ALOT of testing with different Landing gear designs suitable for demanding carrier landings! All that weight suddenly slamming down & @full throttle.

[@xpeterson]

YellowBlue RC ? The idea behind a trailing link suspension is that when compressed the wheel moves not only up but back as well. Say for instance a wheel like this were to hit a road side curb too big for the wheel itself to go over - a regular suspension would come to an abrupt stop. A trailing link suspension would absorb the forward shock while the force pushing the wheel back would also lift it over the curb.

[@toolbaggers]

@@Renatodonadio I didn't know Vespa made dirt bikes. Oh ya, they don't. They make little runabouts perfect for getting a morning cappuccino.

[@MrNavyman53]

Now make them retract too

[@Hellsong89]

Pretty easy actually, just make hinge mechanism and put servo to operate lever system

[@SammSheperd]

the hard part is making it lock in a rigid down posision

[@ZicajosProductions]

And finding space where the gear would go so as to not drastically affect the CofG in relation to the CofL.

[@BeezerWashingbeard]

A good tip: The shocks should depress with 15-20% under only the weight of the plane itself. That way it helps with holes AND bumps.

[@alisioardiona727]

You better not because with the weight transfer when they depress makes that side depress even more so it goes from tilting one side to tilting the other side all the time. It works if you put a torsion bar like in car suspension but it becomes very complex.

[@scellyyt]

Like if you enjoy the sounds of frequency modulation from a brush less motor

[@flavortown3781]

see if you can find a stiffer spring they look under sprung, but damper looks great

[@T1Oracle]

Jacob Westphal I was about to say that. They looked great on take off but bottomed out on landing.

[@PeakTorque]

Disagree. They look almost perfect. Most full scale oleostruts fully bottom on a hard landing.

[@harlyquin]

Cycgnr i agree, they look pretty good, no need to be stiffer, they bottomed out only from the much to hard landing.

[@ROTAXD]

Jacob Westphal maybe just add a simple 1/8" preload spacer. Springs look a tiny bit short for the shock but the spring rate seems about right.

[@zuestoots5176]

@@ROTAXD spring is to strong and not enough dampening. Needs different valving and oil

[@ivanbosyuk4175]

Of course they r shocking, u got shocks on that thing lol

[@YensR]

Trailing arm suspension :) Larger tires will make it even smoother on rough terrain. But the tires act like a spring with very little damping, so if your tires are too bouncy, the dampers (shocks) cannot work ideally. Maybe some rubber foam tires would work better than the air-filled ones. Not meant as a criticism, your set-up works really well! Just as some ideas if you want to do further projects for other applications.

[@sammvoyager]

YensR - -on our grass runway @Marymoore Park in Wash state we saw foam tires on new kits & they're too small for the Grass & didnt spin freely on its axle. Maybe ok on pavement, but as we see in this vid the pilot wants to land off-road too, so the existing DuBro tires seem perfect.

[@welshpete12]

[@toolbaggers]

because people already came up with that idea and they invented crop duster airplanes. An RC plane is way too small to carry any significant amount of payload for crop dusting anything larger than your own personal garden.

[@hunterjohnson7393]

Sad to know that Samm is no longer with us :( Interesting that as a pilot, the "most fun" is doing touch and go's!!! Re this solution, the issue is the knee bend suspension moves the mounting points of the damper (aka "shock absorber") in an arc, rather than in a linear motion which I'm sure is its intended use (the Triumph TR6 used radial shock absorbers!!). As a result, we're seeing a lot of pushrod deflection because the piston is being torqued back and forth.There are other linkages that allow for more linear rather than radial displacement, so I'll leave that to those viewers who want to investigate further. Also, note that the starboard wheel doesn't stop spinning, while the port wheel does -- better check the bearing surfaces. Generally, nuts and bolts are not designed for use as axles/pivots, so there's a lot of flex from them, as well, so there are better and more expensive solutions. On a budget, all-in-all, a rather good day's work. Well done, Samm!

What happened to him

[@ZicajosProductions]

0:59 Hold on a second; where from/how did you build those metal pieces used to complete the strut? Is there a brief video (or could you provide a brief description) regarding how to build these? Thanks. :) This was a great video.

[@marcelw82]

would indeed love to see that!

[@ZicajosProductions]

Marcel Wey Yeah! It is an ingenious R/C strut design.

[@hackettrc603]

He used a band saw and a grinder wheel to shape the pieces but you could achieve the same effect with a vise/clamp, hacksaw and some files. Aluminum alloy is surprisingly soft and easy to work with compared to most steels. I usually just draw out the outline and use the hacksaw to cut off larger bits of the clamped aluminum strip and gradually work my way down to the drawn outline with the files. You can just use needle files for tight corners. Drilling the holes is self-explanatory, again you just clamp it down, mark your holes, use a hammer and nail to indent the metal so the drill bit doesn't 'wander' and your done. The hard part is figuring out how long the pieces are and where the holes go.

[@Choice777]

Just get square or round metal pipes, use hammer to flatten ends, use a bunch of polyester bushings and bolt together flattened ends to form joints and connect shock absorbers to free end and upper joint. No need to machine cut complicated aluminium parts.

[@3100620842]

Myself, i’d just 3-ply some aluminum from a pop can. No fancy tools required, just super glue, scissors, and a drill for the holes. Maybe a file if i want the cutting to be super simple.

[@grantwes]

Awesome frame by frame, can’t believe how much Flex the shafts of the shocks flex and move around. No way would a conventional landing gear allow you to land on such un even ground. How about a “light weight version” where you could use your same design but just coil the wire landing gear to make a cheep/light weight spring. In no way would it be as good as your design but better then nothing

[@rainerignacio776]

[@Xynthesis_san]

Even though someone probably already brought this up, If you can you may be able to replace the springs/shocks with small air ones in terms it may be lighter and function better since you can prevent it from bottoming out? Just a suggestion.

[@alext9067]

And oddly enough, there is no shock absorber mechanism in those hobby "shocks". A shame, but maybe not needed. I personally would like to see a real damper in action.

[@superbmediacontentcreator]

You might want to get hold of some CAD software with simulation in it so you can calculate the weight, stress, side forces and so forth. You can then also communicate in a common language with tooling and machinists who can make the parts that would better suit your application. Just faking it is fine but not scalable...

[@djstatyk1540]

The results are "Shocking" no you did not. Anyway, the knee of the bracket should be in a flamingo leg position. Too springy imo maybe a we bit less as well, looks like those knee bend brackets will dig into the ground

[@olds97lss]

Now use titanium for the flat pieces and put thin shoulder bearings in for the pivots. Then cover the shocks with a skinny balloon to help reduce drag.

Trailing link suspension.. awesome way to soak up bumps...

[@joescoggins5937]

I'm always frustrated when I see RC pilors who don't know how to land. It's good to see someone who knows the basics of landing a plane. It's the same for any plane, RC or 747. They all (should) land the same, adjusting for wind, etc.
