Re: Runway excursion - canard bent

Sam Hoskins
 

Sorry to hear about this Calvin. those off runway excursions are a real bitch. I know, I've had three of them.

I am very curious why " During testing my tail was very light and I could hear the tailwheel shimmying or skidding around at the higher speeds.  At this point there was no rudder authority when using full aft elevator."

This doesn't make any sense to me.  In a stock Q-2 there is plenty of rudder and steering authority, especially at higher speeds. On your web site, http://users.xplornet.com/~vision/44/Q2fuselage.html  I see you have dual controls with the left cable going to the pilot's left foot and the right cable going to the opposite side.  IMHO this was most likely the source of your problem.

I have seen this type of installation before and have written about it..  The builder (Art Jewett) was complaining of unusual handling and had done several ground loops.  I took it for a brief taxi, then immediately shut it down  Very dangerous.  After some head scratching I realized there was full authority with the left pedal, but it was all squishy with the right.  He was losing all sorts of torque in the system because of the dual pedal setup. When you step of the left, there is an immediate response.  Step on the right pedal and the response was very slow.  If you rebuild your canard I strongly urge that you route both cables directly to the pilots pedals.

Take care,

Sam

This week the objective was primarily to get a feel for the higher speed tailwheel steering.  It turned out to be a two fold test, the repair of canard was the second and it was not strong enough for this incident. 


The future for this Q2 looks like a new Ls1 Canard with the stronger spar style wing.  Also an improved tailwheel geometry.  During testing my tail was very light and I could hear the tailwheel shimmying or skidding around at the higher speeds.  At this point there was no rudder authority when using full aft elevator.

Disappointing...I felt I was close to being finished.  Better to find these weaknesses at the home airport.

Sorry to hear that.  The LS1 For the Q200 moved the axles 2" forward if I remember correctly.  This might not work well on a Q2.  The LS1 won't take a ditch much better tho.   I'd never consider repairing a canard with anything but a cosmetic defect.  Fly Safe,

Missing data

David
 


I have lurked on these sites for several years. I am looking for a spread sheet that had a listing of what people built, such as: engine, prop size, etc. I have noticed that a lot of data and info has been deleted/removed (in particular at the Q1 site). If anyone knows where the spread sheet is or can give me a copy it would be helpful. I am just interested to see some of the variances others have implemented. I am working firewall forward, the rest of the plane is worked out.

Thanks,

Dave R.


A step closer

Hi everyone,
Well I  reached another milestone in re-building.  The propeller turns, causing a nice cooling effect, not that we want any more cooling this year in Alberta.   At last I can see the engine running once again.  I have had it outside three times and done numerous run ups while getting the engine instruments all set up over the last four days.  Looks like next week I can begin taxi testing.

$500 Q2

mylittlemgb <mylittlemgb@...>
 


Just to put everyone at ease the $500 Q2 is just a very incomplete fuselage shell with a set of plans. The plane was started then the builder passed away about a year or so ago. They can't find any of the foam or metal parts just a started fuselage shell.

Tail wheel geometry

Sam Hoskins
 

From Mike D.s posting: http://www.pielandings.com/q200/tailwheel.html

The only reason I have my tailwheel directly in trail is to minimize drag and I believe there is a penalty in handling. I have even considered going to a smaller diameter wheel. 

I once taxied Jim Patillio's Q-200 around and it handled better than mine.

I posted side on top and several other pics of my tail wheel, here on Q-list photos section "GOBOXY"  next to Sam Hoskins.   I can send direct to you if you want.

Sam,
I have my Quickie listed on Barnstomers at an embarrassing price and no takers.  Soon it may be down to $500.

Re: Revmaster 2100 Exhaust

Jeff
Your idea would put the hot exaust too close to your carb intake. Don't change the original design. Just my opinion, but I think you'd be asking for big trouble.

Subject [Q-LIST] Revmaster 2100 Exhaust


 

I ordered a new stainless steel exhaust from Revmaster. When I bought the plane two months ago, there was no exhaust on the plane. 

They tell me that the exhaust will exit the plane on the left rear side of the cowl. I can see on the cowl that the last user of this bird sealed up that old hole. The body work is not yet painted. 
So I asked Revmaster if they could custom build me an exhaust that would exit strait down and back at the rear of the cowling where there is already a lump in the cowl for the exit of cooling air. 
Any input on this? Am I correct for trying to save a small amount of drag that may be caused from the exhaust exiting the left side of the cowl? Would it work out for me to have the exhaust exit the cooling air exit hole? 
Am I wrong for trying to re-invent the wheel here? I also think it would look nicer of that would possibly work.

Yes Sam, I know, it sounds strange, I will check again to be sure that what I am seeing is real. If I can figure out how to get pictures uploaded from my iphone onto this site, I will post some. Thanks for your input.

Re: Carbon Fiber Q-2

Interesting, never heard of a CF Q-2.  What portion did you examine?  Fuselage, wing?

Are you sure it's not the paint primer?  The original finishing method called out for a black primer that was designed to protect the epoxy from UV. Maybe that is what you are seeing.

Why is my Q-2 outer layer appear to be made from Carbon Fiber? 


The person i bought it from said it was built of carbon fiber, I didn't believe him so I sanded, and/or pealed a few spots and see that it is, from the out side, Carbon fiber. But from the inside, it looks traditional, glass. 

I heard that Carbon fiber could be 4 times stronger if done right from the start vacuum bagged and all, however, if not done correctly it may only be 50% stronger. 

Anyone want to help me understand this?
