Thanks for that link Eastw. I hadnt seen that. Very good info. I personally dont understand Polar or are they Renolds numbers but the airfoil section is good to have. Thats all thats really needed to

I bookmarked this link some time ago, besides the words Rutan and Amisoil I can't vouch for any real connection though lol http://wingsofaero.in/rutan-amsoil-racer-canard-airfoil/

Hi Shaun yeah a really neat airplane and one of my favorite planes to date. Mike Arnold built probably most of the airframe of the Amsoil Racer yes. Mr. Arnold is a huge inspiration to me and should

Hi all, I thought it would be interesting to get some conversation going to compile all of our knowledge/see what we can learn about an airplane closely related to the Q's. The Amsoil racer is the

It resembles a Rutan Quickie made from an Aerostar Front end that uses those Pallet Jacks to move it around. Seems totally reasonable to me, still, I don't know how they'll get it flying with those

Nice! Thanks for that.

It is how you calculate what loads a flight control system should be able to withstand. It is based on a statistical analysis of what pilots can develop on flight controls. It isn't intended to be

Good stuff!!!! I was wandering about this same stuff but just assumed history has proven it safe...... Thanks Dustin Graber Q2, restore project

Hi Matthew,You wrote: 14 CFR 23.397 defines these loads - its 67 lbf at the stick for roll, 167 at the stick for pitch and 200lbf at the rudder pedal. These are the basis for your analysis but what do

Hey Q2 people, So I had a couple slow days at work and since I've been in more of flight test mode than design mode I figured it'd be a good exercise to margin the quickies control system. I've spent

Got in my first flight of 2019 today. It was my ninth test flight. The temp was 3C and visibility clear with slight breeze from the south. This was first flight with my revamped crankcase vent

I think you mean this one, Gabor. Your link does not work. https://youtu.be/nMuHh44upfA Jay

Hi Rob, You can't stop tip vortices forming but just like with end plates or winglets you can minimise them and their adverse effects. In the case of the tandemwing set up described the best induced

Hi All, I would like to suggest this video to all of you who are interested in simple aerodynamics. The presentation made by Mr. John Roncz. Cheers from Hungary Gabor

Hi Gary, I seem to remember from aerodynamics classes that you cannot stop the tip vortex from forming, it's an integral and inevitable part of lift generation. I mean the horse-shoe vortex, as

Hi Rob, Very interesting link. Yes I mean tip vortices on one side oppose each other and of course the same thing also happens the other side. I am not of course saying the vortices on the same side

Here's a more complicated drawing, showing the vortices revolving around each other before merging. It's more like figure 1 posted earlier, but does not fundamentaly change the principle. Rob
