Experimental Super Cub Episode 4

In this video I discuss why I choose to go with a tubing kit for this project and my experience building the fuselage to the experimental super cub

Great review, it will be interesting to follow your build.

[@sailorlee15]

thanks for watching!

[@mister_aanderson]

Very helpful, thank you!

Thanks for the build series! Cool project! about the Super Cub Plans, what/where did you get them? AND does VR3 send assemble plans with their kit? I am guessing/hoping they have a specific order of assembly. AND......if you have time can you talk about your build space, table and equipment in a future video. I'm an EAA member and our club is following your build. Thanks!

Thanks for watching! When Building an experimental cub (not from a kit) most people buy the northland plans ($60 google search it) and then use those combined with the drawings on supercubproject.com to fabricate most of the parts. With the VR3 kit you are provided with drawings and some assembly guidelines. I have never built anything out of tubing and my came out very nice! I'll do a video on build space soon.

Looking good but still a bummer that you didn't show how it all went together.

Keep it up

[@marcericdavis]

Hey Lee. In one of your vids you mention that the fuselage can' t be built flat on a table and tipped up like other home built. The plane for the Wag-Aero J-3 cub do just that. You build the sides flat then tip them up and add the top and bottom cross members to form the curves. Did you consider this idea and reject it for some reason? Is the some relevant difference from the PA-18 to J-3 that makes this an issue? Just trying to understand the options. Thanks

[@sailorlee15]

Marc, I'm not familiar with how the j-3 is built but the VR3 kit needs to built upright. The longerons have several bends in them and the process that they recommend works well for building this kit. Hope this helps.

@@sailorlee15 Here are two links to both the original Piper Cub assembly circa 1943: kzbin.info/www/bejne/h2fUYomBqLmYgbM&ab_channel=ChristianSturm and the flat table construction of a Wag Aero J-3 cub: kzbin.info/www/bejne/fXSuZ3eAnLydf8U&ab_channel=2FlyAmerica Note specifically in the Piper video after the sides are welded flat when they are placed in the vertical weld jig and clamped into place that the tubes are gently bent by the clamps.

How much were paying for the actual profiling vs the profiling plus materials?

[@MaxRunia]

I want to sit in mine and make airplane noises 😆 I'm a few months behind you

[@phillipray5957]

Very helpful review. Does vr3 give you a recommended sequence for final welding the clusters?

[@challenger2ultralightadventure]

What did the kit from VR3 cost? I currently am rebuilding my Challenger 2 which is on amphibious floats. But I'm looking for a new project build and I'm curious what the tubing kit cost.

[@sailorlee15]

$4200 for the tubing kit.

Will you be adding the third seat/upgraded baggage compartment?

[@sailorlee15]

yes, extended baggage and deciding on L21 windows now.

[@nogonova]

Where did you get your plans from?

[@redmammoth3060]

how many hours did you log into building the fuselage?

[@sailorlee15]

about 45 in the fit up and tacking. Finish welding and all the bracket fab comes next.

[@ramzesi4750]

Is it ordinary metal or something special?

[@asennad]

It's made from unobtainium.

[@dvanraay3]

It's 4130N, seamless aircraft grade tubing

@@dvanraay3 I make it with soft plain steel I think will justify it

@@ramzesi4750 not funny to joke about using low carbon mid steel tube.
