Ridge Runt Evo

[Hawaii Sloper]

The wing center section got a little more attention. Actually a full redraw. All printed parts have been created and fit and finish is looking good on them. So onto the wood. Here is a final look from the CAD.

Is that gonna be a lot of leverage on that rear mounted nylon bolt?feels like unless the front clips in somehow it could tend to lift away at the LE. Probably wrong but just throwing the thought out there.
* on closer inspection I see how you have the front pin angled into the 3d printed section. Nice alignment and attachment solution.

I think it will work fine. Not 100% sure until I build one and test the joint.

@Wayne earlier you mentioned the nylon wing bolt to avoid damage during "missed" landing. The thing I noticed however is that the front attachment pin goes into a hole in the front former, and it seems to me that if the wing gets hit and the bolt shears that front pin is going to break the former and/or the fuselage.
The caveat here is that I am not much of a builder...crasher yes, builder no

 

[Wayne]

Yeah, I abandoned the other plan and went with the traditional front pin and rear bolt. Did this to strike a balance of simple and functional. This wing is very easy to build, so if you manage to slam a wing tip into something, the wing will give itt's life and either a repair or new wing will be the cure. Think the fuselage will be fine in this sort of incident. The fuselage should be able to take a fair amount of abuse. We will offer replacement wing kits for CHEAP should they be needed.

If you like, you can easily convert to rubber bands. Top of the wiing will take bands with no issues, a little plywood on the trailing edge...

We dry fit the wing parts the other day and they are looking good. Should be an easy build.

I'm in for a group build.

Not to beat this to death, but I was thinking the front attachment could be a half circle that held the pin centered and down, but not trapped.

I would be a go for a group thing, as long as it can be done before the scotch kicks in!

That was my same thought about a slot instead of a hole. Could this allow some wiggle to be introduced if not built properly or if the wing/fuselage gets a small amount of compaction in the balsa over time? Could definitely save some damage to the fuselage section if the bolt was to let go.

A nice simple build. Sanding takes the most time. Spar is super strong.

 

[thenated0g]

Looks nice and light.

 

[Wayne]

Very happy with the ease of build and end product is looking good. Should have a fuselage built up tomorrow. Just cutting out the parts now.

Looking good. Nice grass too!

Looks sweet, Wayne. I love the semi-circle braces between the ribs. Very stylin'!

I can't take credit for that one, Rafael's idea. We didn't like it at first when he suggested it, but he drew them up and installed into the wing we all loved the look of them.

Oh, and well, turns out this is a very easy build. We built this out in less than 2 hours, and that is with us going slow on the first build and noting small issues to adjust.

I honestly expected to run into some unseen issue, but it sailed right along. Sure enough, the new bulkhead concept is a winner! Self jigs very well if you follow the correct sequence.

Very pleased.

That looks awesome!!!

Maybe when you sell the kit you could have a recommended electronics and hardware package to complete it?

The grass in the backyard is amazing right now. Should stay nice until summer. Just needs a bit of water to get things going:

That was my yard a couple of weeks ago. The creek is usually about 4 feet across.

 

[Chris]

A little more water should do it!

 

[thenated0g]

you guys needs some rc boats

Praps some Springer Tugs

@RafaelAvila laser out some tugs!
