Re: Brake lines

Jay Scheevel
 

Hi Mike,

 

I used custom lengths, as you will need to also. I had the hoses pre-made with fittings pre-installed from DiscountHydraulicHose.com. The specs for the tubing from them is: “1/4" SAE 100R14A PTFE Hose Assembly”. This is a stainless-braided-sheath PTFE tubing. You can custom design them on their website. They have an website widget that is easy to use. When I was ordering the hose, there were a variety of fittings. I selected “T09-04-04 | ¼” JIC Female Swivel fittings” because they had the shortest swaged sleeve, but was still about ¾” inch long, so plan for that much host to be rigid on each end. They tell you how to measure and do the design. You can choose from straight, 45 and 90 fittings. These fittings are not small, so plan accordingly.

 

The ¼” is the smallest PTFE braided tubing they have, so you will have to buy some male to male 1/8” to ¼” adapters (37 degree/JIC), plus some nuts and collets for the 1/8” tubing. These are available from Spruce, I think. If not, then a hotrod custom site, such as JEGs will have them. I chose this hose because price per hose was so good and the quality very good.

 

Make sure you use a professional quality flare tool to do your flares on the stainless. Best to do most of the flare, turn the tube 90 degrees in the retainer and finish up the flare. This makes it nice and symmetrical and the seal perfect.

 

I suppose there are places you can buy similar 1/8” hoses, but I could not find them, so I went with these good quality ¼” ones. The combination of the 1/8” stainless hard-line and the ¼” flexible works well and will last longer than I will. Good luck.

 

Cheers,

Jay

Does any have a set of exhaust stacks from the original kit that they would be willing to sell? Mine are starting to have holes in them.

Re: Nathan Peck's Quickie Q-Tour is uploaded to YouTube

Nathan,

 

Your problems with the poor performance you’re getting with your Rotax are almost entirely traceable to your propeller. Your descriptions of your takeoff struggles and limited top speed at reduced throttle (and over-revving) are classic for a two-stroke engine that has a prop with too large diameter and not enough pitch. Mike Arnold went 213 mph on a (barely) 65 hp Rotax; I think you could easily be cruising at 150 mph with decent climb if you’d get a better prop, and I don’t think you need to have a variable pitch prop to get there. You could start by cutting down the diameter of your existing prop and increasing the pitch. The attached spreadsheet indicates that a 48” diameter should be maximum diameter for an airplane full-throttle top speed of 150mph if you’re using a 2.58:1 gear ratio. If you’re using 2:1 the maximum diameter shrinks to just 43 inches. (Assumes maximum engine RPM at 6800 rpm; you’d likely want an even smaller diameter in order to cruise at less than full throttle at 150 mph.)

I’ve attached the Sport Aviation article for reference – I’m not suggesting that you should  build your own prop, but the article explains what the spreadsheet is doing. I’d be happy to work with you on a custom prop design if you want.

Thanks, Jim.  I wish I wouldn’t have sounded so negative toward the Rotax.  The are notable pro and cons to every power plant.  The Rotax is and has been fine, but is t perfect.

Re: Looking For Q2 and 200 Projects, Midwest Prefered

Cameron Camp
 

Not in the midwest, but getting ready to put my currently registered Tri-Q200 up for sale, can’t fit a dog in the back seat as best as I can calculate (or luggage) and put it on floats so working on a Glastar project. It’s missing an engine, but everything else is there, ready to paint, assemble and fly (minus prop). You might be able to talk Phil Langford into selling the engine back to you (or not). This has tons of upgrades like Velocity landing gear, sliding canopy, streamlined wheel pants, and my friend who restores classic cars did the body work with Jim Patillo’s cowl inlet patterns. Haven’t thought of a price. Has around 500 hours of flight time before it was dissasembled to clean up the fiberglass finish to a higher degree. Dog not included. It’s in Oregon. The plane. Well, the dog too.

Thanks,
Cameron

John, 
I did many times reset the prop pitch, for as much as the runway would allow.  I was going more for speed, but in the beginning had it set up to be quite a rocket off the runway and adjusted from there. 
I didn’t make any significant changes to the firewall. I was referencing a beam to extend the length of the trailer for highway transport. 

I, too, would love to hear from other folks with Rotax Quickies. 
Thanks for the comments.

Hi Nathan,

That was an insightful, honest and thoroughly interesting presentation.

As you rightly point out there is little point in lugging the penalties of extra weight and reduced margins if you cannot reap the benefits of extra power. It seems that the real world power to weight ratio did not change that much. Did you ever depitch the prop to the point where you could get into the power band for take off?

You might want to consider the HKS if you ever wish to re power.   One of the other Q1 contributors mentioned that he used the GCS propellor vs your warp drive. Warp drive props are heavy.

You mentioned cowl cheeks as having a possible blanking effect on the rear wing.  It did not seem to have any effect on the amsoil racer.  Did Jon Findlay have cheeks on his VW powered Q1? 

I would interested to know what modifications you made to the firewall to cantilever the engine from it,

It would also be very interesting to get a similarly honest report from the other rotax Q1 operators.   

Thanks again

I have used 1/8” stainless steel tubing for may brake lines, with a small PTFE (Teflon) segment at each end for flexibility. The PTFE will take more pressure than the Nyla flow, and is good to 500F. The stainless will last forever without corrosion and also is a narrower line that will take up less room in the corner of your elevator slot core. Easier to bleed, since the interior volume of the tubing is very small, bubbles move quickly through it. My 2 cents.

It's not too bad to replace. You can run it in the lower corner of the elevator slots. You will have to cut a slot in your wheel pant to bring it down to the brake but once you get started is not really that bad.
