Bill,

yes, I suppose so, though I don't know any other brand. But you can try the 23824RB (2.375" x 24") blades from Aerobalsa.

Ok Jochen I have a set of the 23824RB blades on the way. About how long do you think It will be before I see them here in the states? you aren't in the states are you.

Bill,

I'm in Germany. But I don't think it'll take long.

When you use these wider blades, drill the holes that will hold the blade at the same distance from the leading edge as given in the plan.

I always think that the 2" blades on my Minimum look wide , these 2.375" blades are going to look even bigger

Hello Bill,
Good to see another Minimum(ish) build in progress. Do you know what the ready to fly weight will be yet? It looks as if it will be much heavier than the original plan, but I also saw the thread about your larger blades so this may work out. Good luck with the Redneck engineering. All of the "Mum" designs are cool, and usually describe the size in the name. I think in your case perhaps you could name yours the Plumbermum since it's constructed out of plumbing pipe.
Regards,

Got -ya Now this is probably a question of preference but should I build a tail section with a functioning rudder or a ridged one?

Hi Boneswamped I read your Bio Hope your not in the pilot seat when you crash-um , Although the feeling is somewhat the same when you put a lot of effort into building some thing and it becomes a lawn DART. Below is my latest finished project waiting for some warmer weather to TEST FLY this one. Bill

Like I said I like the wow factor at the field.

Bill,

if you want to ROG, you'll have to build a rudder. Otherwise it's a question of preference.

Rog??? Hold it I think I got R O G roll on ground? This is what I have in mind I use an airplane tail wheel assembly mounted on the front and let it pivot freely with a rather large wheel, build a functional rudder and let the front wheel seek is own direction aided but the force of the rudder inputs what do you guys think?

ROG is "Roll off ground" as opposed to hand launch.

It's amazing what you can do when your inspired.below is what I have so far.
I think I need more space between the prop and the tail feathers. What do you think? It looks like I could use a micro receiver have to go to bed and dream up some kind of storage for the ESC, receiver,Battery,and a nest of wires. enough for one day See ya later guys Bill

It's looking good Bill.

If you do consider adding a rudder, I found that extra bracing is needed for the tail otherwise it tends to flex when rubber is applied, and that has odd results ! (like reversed controls ).

Bill.

as long as your prop doesn't hit the tail that's ok. But you should do some tests to find the correct motor offset:

What's the weight of your gyro up to now?

Oh-Boy I got my sheet of garolite (gf) but I think I ordered the wrong thickness It is 1/16" that is too thick isn't I think I need 1/32" sheet right?
I must have missed somthing in the conversion table.

Bill,

the original hinge is 0.02". I've flown a 1/32" hinge but found it too stiff.
