Big Stick Laser Cut Balsa Kit 1060mm (Kit)



$30 from HK, I had an old brushed motor from and old Parkzone FW-190.



Here goes!

I've got the firewall laminating next to that old brushed motor.

Cool! With your building skills that kit should be a piece of cake, I look forward to seeing it come together. That motor combo is actually really good with a GWS 10x6 HD prop. Even with the stock (10x8?) drivecalc says you should be drawing around 12 amps for 17.5 oz of thrust on a 3s 2200. I would recommend an APC 9x6 or the GWS 10x6 if you can get either, as with those you are looking at 17 oz of thrust at 8 amps or 20 oz of thrust at 8.1 amps with those combos.

Wow, thanks for the calculations! The GWS 10x6 looks like the way to go.

One of these days I really need to invest in a magnetic building board...! How are the "instructions" with this kit, as good as the typical HK balsa kit?

 

[bicyclemonkey]

The instructions are very minimalist compared to what I'm used to but it's a pretty simple kit so it won't be an issue.

This kit will be the perfect guinea pig for Harbor Freight wood glue.



Although for laminating pieces together, I normally use thick CA. My thick CA was all dried up so I decided to try some old contact adhesive that came with some long forgotten foamie.

Looks about normal for HK laser kit instructions. Watch the contact on lamination's, once you touch there's no going back!

 

[bicyclemonkey]

I'm going to go off instructions a little bit here. The instructions show gluing in all the fuse formers on one side of the fuse. The problem is that the fuse tapers from just behind the wing to the tail and from the leading edge of the wing to the firewall. If I glue them all at 90-deg angle they won't line up right with the other fuse half.

 

[Joker 53150]

Ignoring the instructions on a HK kit is very often good advice.

 

[bicyclemonkey]

It's coming together. I find the tab-n-notch style much more of a pain than a traditional die cut style kit.

 

[bicyclemonkey]

OK, clamping it like this worked much better...

 

[Joker 53150]

Is that whole fuselage light ply or balsa? I'll assume light ply since the structure is so light. That's the kind of design that calls for transparent covering, or a light color with LEDs stuck inside!

Those bar clamps are great, every builder needs a bunch of them.

 

[bicyclemonkey]

The whole fuse is light ply. I did find some balsa after digging in the bag. Looks like that'll be for the wings and tail.

One nice thing about tab-n-notch is that most pieces snap in tight enough to not need clamping.

 

[bicyclemonkey]

This is also in the running as well as the old brushed electric motor...


ASP Hornet 0.15 Two Stroke Glow Engine

Interesting, that structure doesn't look strong enough to handle the vibrations from a glow engine without some serious reinforcement. I would think it would break up after a few flights. Is it really that tough?

 

[bicyclemonkey]

I think it may be fine with a small glo engine. I'll decide for sure later. For now, The top and bottom sheeting is done.

I ironed the bottom sheeting but they were easy to clamp so I did that for the top.

 

[bicyclemonkey]

Looks like someone already had the same idea as me regarding the .15 size glo engine.

Looks to be pretty much the same model.

Nice, BMonkey! Good to see you back!

 

[Foam Addict]

Cool, sounds good!
