Long-EZ/Cozy Hidden Rudder Bellhorn plans

Recommended Posts

I sent in my order to the Rutan Aircraft Factory a couple of weeks ago, holding my breath for whether I'd receive a "Sorry, we're closed" response, or the actual plans. I received the plans in the mail yesterday, with instructions relevant for new construction. Here's a quote from the plan guide:

 

We believe this installation is an improvement over the original [Long-EZ] plans (large rudders) from a practical, operational sense as well as simply making the airplane look better.

I've heard rumors that the RAF is shutting its doors, so if you're thinking of including these in your plane, you best spend the couple of dollars now.

Is RAF the only place for the hidden bellhorn plans?

 

DId you order the "Flush Bellhorn Plans" from the RAF website for $14?

 

Thanks.

The bellhorn plans, along with the full-span rudder plans, come on the CDs from Terf as well. It's a little more expensive to go that route however.

I have the TERF CD and that means I have the drawing for the control horn. Now for the problem..... There is nothing on the drawing to use for scale. The only dimentions are for the holes and I do not want to use them as a reference. I need to know the length of the horn and maybe a width so I can be sure to have the correct scale.

 

Any and all help would be great. I will be sure to redraw the parts and post them for all as an ACAD file and Solidworks file.

You can buy my plans if you want. I'm going to do the blended winglet instead and can't use them.

I've read that there is less rudder deflection with these things compared with the plans design. Is this true, and if so, has anybody found it to be a problem?

Typically if you go the route of the higgen belhorn. you are also building the larger rudder as well. The deflection is a result of the accurate placement of the belhorn ...... so the answer is no, you don't lose anything.

So if I build my rudders to plans, there will be some loss in effectiveness with these bellhorns???

The hidden belhorn plans and large rudder plans were designed by rutan aircraft for the Long-EZ. I believe the Cozy is already using the large rudders.

 

I am not aware of any reduced rudder authority as a result of installing the hidden belhorn according to plans.

With a Cozy, yes, but as TMann points out, you can build the rudder control surface longer to make up for the difference. However, this may not be worth your while (or worries).
