Robert, your panel is similar in concept to mine except I carved out as much space possible for knee room. You may want to sit in it again with pedals in place before finalizing your panel. The higher

Ben, That's pretty much exactly what I've been saying; To use degree-two single-span (degenerate) splines is, mathematically, exactly the same as to use conic Bezier curves. It's just a choice of

Johannes and David, I have had good results for this kind of problem using Bezier curves instead of splines. Believe it will be easier to get tangent at joints. And now to throw a "hand grenade" into

Danged email down sampled my picture so it’s all fuzzy looking. Here’s a better image:

Johannes, Here's a start on a Q-200 firewall using the method of conics that I suggested. (Rhino CAD file attached.) As you can see, either the original drawing or the scan is not

Currently, to make things match the table top would be at WL -2.8. I will update with the reference dimensions from the firewall David sent. -- Johannes Weissmann

Check me on this Johannes, but I am pretty sure that the top of the jigging table is WL0. I think that’s correct. Cheers, Jay

Johannes, My apology! When I referenced Appendix Sheet 3 I was looking at the Q-200 Engine Installation plans Appendix Sheet 3. The Q2 plans appendix sheets have no such annotations. I've attached

Johannes, Please note that all the side view drawings of the Q2/200 throughout the plans are not accurate representations of the silhouette of the actual airplane. The lower silhouette line of the

Yes, thanks so much. I totally forgot about those lines on the template. When I traced the firewall, I was not sure if they really show the fuselage split line. At least in the template I have, they

Johannes, Try to stick to degree-two curves (conic sections) as much as possible, and fit them piecewise with tangent continuity at the joins. Use the control point "weight" on the middle control

Johannes, Page 8-2 shows the 2.9" dimension on the firewall. Page 8-4 repeats the image with the "Shell Split Line" explicitly labeled. The firewall template on Appendix Sheet 3 shows WL 12.1

Thanks Jay, I have used these drawings as the reference. What is lacking, or maybe I am not seeing it, is how to properly constraint WL15. In particular, I never found a way to properly define the

Robert------------  Just noticed your elevator connection to the stick. How are you connecting the elevator bellcranks?  Show us some pictures and we may be able give you some options.--------- 

Yeah, I will have to consider how to mount, strengthen and support the panel in there middle because I won't need the space and depth stream/gyro gauges had. Also, I'll probably scissor hinge my

Johannes. For WL reference sketches please see pages 17-20 of the following linked document http://n8wq.scheevel.com/documents/Q2_Q200_Plans_Abridged_for_Scheevel_Construction.pdf Cheers, Jay

Don't forget to include the mounting brackets and such behind the panel. My first two cardboard panel cutouts didn't take into account the hinges for my forward canopy. But that was ~35 years ago -

If anyone is going to burn up the their time “CADing” the Q2/200 to “improve it in some was, I’d suggest that it be scaled up in a similar way that the VariEze was “improved” to become the

At the current stage I simply tried to reconstruct the existing shape based on the available plans and templates. Basically, I used the fuselage jig and bulkhead templates as reference and in

Oops. I should've addressed this to Johannes, not Robert. David J. Gall
