HobbyKing Bungee - set up and launch

[@rudyho3790]

We install two foot longer main rails; No intermediate connecting clamps whatsoever! No bungee; Using Full length of rails, Full throttle, full up elevators gets that sailplane on it's way up!! Love the test success flights...☝️😁👍

[@southamericanrocker]

Thank you! At last someone gave some thought on to why do people want to look at a launch video!

[@Lycoming320]

I use 100 ft of surgical tubing and 200 ft. of spider wire fishing line and get launches to 150 ft high with no problem. Need a big area though. My bungee hook is a picture frame hangar hot glued slightly behind the CG to keep the nose up. Enjoy!

[@salmenda]

Video?

[@nickhayley]

Great set up and explanation. I think you meant to say that there's a lot of POTENTIAL energy stored in the bungee cord. But we all understood. Cheers!

[@PNH750]

The prop must be very close to the tow rope at the start of each launch.

[@bluedog9601]

How did you make a hook for the pull on the aircraft.

[@jbfordfocus]

I think that it was a skid mount, that I then just carved out a notch .

[@MrKenwillis]

jbfordfocus I like to know how heavy was the plane in this video up all weight? Thanks

[@moochasas]

Any tips on the amount of tension used and the length of the cord use?... thanks in advance.

[@stephenhathaway269]

moochasas using a luggage scale, tension the bungee 6x the model weight

[@HumbleHeartMinistry]

This would be great for the hard to launch flying wings, but for a glider its a bit overkill. Great video though!

[@SemteVruchte]

Do you still have it?

I just ordered a HK bungee launcher. How to make a hook to put on my plane

Hello. Can KZbin Tello me please the angle of the plataform?

How do you make a hook for the plane...

[@allenmoore9848]

nicely explained!

[@JohnVHRC]

Awesome

[@PatandkenLarson]

What kind of hook is on the underside of the plane? Glued or screwed on?

[@jbfordfocus]

I cannot remember, it was 7 years ago. Just glue I think.

[@chillville5571]

Do you still have this launcher?

[@notamage9956]

Hey hello, I have a fixed wing weighting about 2kgs. The results you get in your video look very promising, however would you recommend this for a 2kg fixed wing? Or would it end up in a total failure?

[@fahrvergnuugen]

It will work, you just need enough bungee strength.

[@nicov.2151]

you need to have 5 to 6 times the weight of your plane in bungee tention, so in your case it should be between 10 and 12 kg's

[@fahrvergnuugen]

N Ver any advice on whether it’s better to double the bungee up?

[@nicov.2151]

i rather not double the bungee cord, as it tension time is cut in half, and with a 10 /12kg you have a enough tension on a single line. I would check the tension before launch with a fishing scale if you have the right amount of tension. if you cannot reach the amount you need, you can consider doubling the bungee line, do not knot the bungee line together but run it over a pully which is then attached to the line, then you have even tension on both sides of the bungee cord

[@fahrvergnuugen]

N Ver thanks! I’m still trying to get mine to work reliably. I’m launching a strix goblin that weighs around 4.5 lbs. I bought a 10’ bungee and doubled it but it doesn’t seem to be enough. The other problem is I’m using it in the winter and the tubing loses its elasticity in the cold.

[@joewoodchuck3824]

The need for a bungee launch with a powered plane is lost on me.

[@nickhayley]

This glider is an easy hand chucker. A large edf with no gear on thick grass when flying ALONE totally warrants this kind of bungee. Im looking at a 90mm 6s edf falcon without landing gear (ripped off) that would definitely need bungee. Just not sure how to mount a hook on the belly.

[@jbfordfocus]

Hi there, this was just a test for launching a larger EDF. I just needed to try it out first on something simple.

[@jatinsahni3021]

@@jbfordfocus Hi, black rope is bungee elastic rope or non elastic rope? Thanks.

[@rafaelalves1583]

Launch 4:16

[@conradallum4323]

WHY""?? why would you need a bungee launch for an electric sailplane

[@audigga4396]

try launching a flying wing with a pusher prop!

[@blackbirdxx928]

The plane has a motor, this must be for someone with only one arm?

[@joefalcon870]

and someone like myself who has limited feeling in there hand after a angle grinder accident.would give me more time to get on the controls, without adding excess landing gear weight?

[@blackbirdxx928]

@@joefalcon870 For your situation there is probably a benefit.....got to watch them angle grinders. I have one of those old school 9in black and decker deals that weighs close to 30lbs. I run a 12in table saw blade in it to cut up old boats..i put a 2ft side handle on it....it cuts like hell but the second i pick it up my brain goes into *pay fkn attention* mode...its gets a little out of control once in while...i just make sure i keep my arms straight. I also have a weed wacker with a skill saw blade...been using both for years...the one that got me...5 in angle grinder with a cut off wheel, buddy borrowed it for like 2 min...must have set it down with the blade down...i didnt check the blade when i picked it up, the angle grinder didnt have a button it had a switch...the second i started i felt the vibration and i just threw it...blade came apart just as it was leaving...1/3 of the blade stuck me in the thigh...at least in inch deep....feel for ya not having full use of both hands....i barely get by when both of mine work properly

[@toze4172]

A catapult to launch a glider !!! seriously?

[@Pijawek]

Overkill in this case, but it's a very usefull tool for large flying wings. They are a real pain in the arse to launch - either you throw them above your head risking prop in the face or sideways risking smashing them in the ground. This is a great alternative!

[@upperechelon3456]

These launchers are a godsend when it comes to launching my Talons and large wings. It also comes in handy for launching my 3M gliders which are to heavy and unwieldy for my 65 year old arms to throw. 😄

[@nickhayley]

I love watching people come up with fun ways to keep the hobby interesting, but this does seem overly complicated for a simple powered hand chuck glider.🤷‍♂️

[@BryonGaskin]

Ranger 2000 Glider..........hand chuck no problem. AR Wing Pro...........hand chucking can be a problem
