Hi Rob

I do not have a web site but email me at n345jm@gmail.com and I'll send what ever I can.

 

Jack

Gee Tom, that looks like a split rudder. Go for it.

I did not want to get involved in this issue but your statement Drew is absolutely untrue, (Jack and company, me ,myself and I) did exactly as Mark suggested and sent to me. I wish that people would not comment on issues which they no nothing about. I sent my drawings to Mark in 2005 about the blended winglets ( I will post a copy of the original drawing as soon as possible). I weighed blending the winglet already attached to the wing, which are what Mark drew up for me and has on his wed site and was also on the forum. I did not like this process and decided to go with the new winglets with the extension or continuation of the wing shear web and spar cap to the top of the winglet, my design. Mark furnished the techinical information for the proper layups for structural strength, period. I do not recall ever mentioning the size of the radius of the blend but if you look at the original drawing I sent to Mark, the12 inch radius is not accurate. A 12 inch (circumference) is closer to the blend on my winglet, actually the outside of the radius came out to 13.5 inches, the inside 6 inches is circumference, not diameter. This is the blended winglet I designed and installed on my E Racer. I tested the AC in all attitudes and they performed almost exactly as I hoped they would. I alone decided how large the circumference during my design process to keep the bottom of the rudder as low as possible, the larger the blend, the higher the bottom of the rudder is. I also designed all the linkage, a very simple system. I will post the drawing as soon as I figure out how to attach to the web site. I have the right winglet with a portion of the wing saved from E Racer113 and in the near future will test the actual strength of the blended winglet as I designed. I will do a professional video of the actual test, outside to limits and inside to destruction.I will send this video to Mark for what ever he wishes to do with it. Mark was a tremendous help in this program and I would have never attempted this on my own. I wasn't born yesterday but techenical and structural knowledge is a must with a serious modification like the blended winglet. Just setting the record straight.

It was posted in the Oct Sport Aviation magazine at 62,500.00, for 180 hp to altitude 180 and 70% to 300. Don't everyone jump in line at once. Thats expensive.

 

Jack

I had-have a electrical nose gear retract system in my E Racer, I had to modify the attach brackets that Jeff Russell designed for the cozy 4. I have all the drawings for anyone interested, works great and cost about $400.00 if you make your own brackets. Also has a manual crank down if the electric ram fails.

 

Jack

Right on Joe, with LE plans, the E Racer is a good build and a fine AC.

If you are interested in a Defiant, there is one for sale. Barnstormer.com - experimental - Defiant. I no nothing about this but looks good from the photos, will save you 5 years of work for less than the materials.

 

Jack

Flying a CANARD , Priceless.

 

Jack

Well I guess I passed that one TMann.

 

Jack

I had an all alunimun v6 chev built up with a supercharger , 300 hp and had

21K invested before I went to the lycoming. A good light weight high performance auto engine is not cheap, plus all the cooling, psru, and time.

 

Jack

Opps, sorry about that, your are correct on the name.

 

Jack

Check on the Velocity website, a Mr Rivera has had a pair of camera's on his Velo winglets for quite a few years. Look under builders and it is on his web site.

 

Jack

 

We are planning on putting a mini camera out on each wingtip. Anyone know of any clear color quality cameras and where to get them. the wires will run through the wing into the cockpit and most likely be hooked up to a mini laptop!! Any help. Thanks

Mainly looking for the in excess of the 200 HP, lighter than the angle valve. I like the idea of the smoothness both for comfort and for the ability to use a IvoProp. Don't know if I want higher compression, however the stock engine is supposed to produce 225 hp, I believe. I also like the fact that you can remove a panel on the top of the case and view all of the innards. The considerably lower price is also a plus.

Hi Rich

I believe Nat installed the Franklin is his Cozy 4 and was not pleased with the weight and performance, reinstalled the Lyc 0360 back in about a year. The Continental 360 is about 75 lbs heavier than the Lyc 360 also. There is a fellow at ARR with a Franklin in his velocity, if you would like I can give you his name and phone , if I can find it, and see how he likes it. I know he has had some problems but not what they were. IVO is out with Lyc engines.

 

Jack

how do you test for an increase in speed at 140 kts? how do you know it is faster? top speed is easy but testing at half speed is difficult. also did it change landing speed and dutch roll at low speed. removing the lower winglet does make a difference. does the radius help on dutch roll over the no winglet E racer wing. this wing was also tested on an E racer with a much higher wing loading then the standard cozy IV has. we will have to wait to see it on a cozy IV before we will know the real effect.

What I did to give a very close comparison of airspeeds is to compare all my airspeeds during 8 years of testing for cooling and airspeed measurements before and after the blended winglets.. I had littereally 100.s of documented airspeeds at all DA and oat temps. How I calabrated the airspeed was at engine rpm say 2100rpm= 150 kts without the blended (same oat and DA) the airspeed would be 160 kts with the blended winglet. The speed would increase every 100 rpm, everything equal, + 10 kts. The drag on the original wing/winglet was definately a drag area and the blend made a significant reduction in the drag. It was really great to see at a normal power setting you were seeing a 10 kt increase at all settings, all being equal. The ERacer as you know did not have lower winglets and I flew the AC for 2-3 years that way. I saw the article on Klaus's website and added the 3 trailing edge fences. Lowered my landing speed by 10 mph, worked really well although no gain in speed, at least not noticable. When I blended the winglets, I flew without the trailing edge fences and found they were not necessary, all control inputs and landing speed were idenitical to the original winglet with the trailing edge fences. The blend definately helped the duch roll as an the original wing/winglet. The reason I kept the radius of the blend as small as I did was to keep the bottom of rudder as close the wing as possible to hopefully eliminate as much duch roll as possible, made a good decision on that. Time will tell on the Cozy.

 

Jack

It was very consistant from 140 kt and up. I chose to go with the approximate 12 inch diameter to keep the rudder down as close to the wing as possible. The larger the blend the higher the rudder and the taller the winglet would be to maintain the same rudder control. I also think it would look a bit odd a large radius of 12 in , or 24inch diameter, on such a small AC. The blend accomplished very close to what I anticipated, with no adverse handling characteristics. I was also able to eliminate the trailing edge fences I had on prior to the blended winglets. The blended winglets on Dennis Passey's Cozy are very close to the ones I had on my E Racer, a few subtle changes. I think some where down the line someone must have confused a 12 in diameter with a 12 inch radius blend.

 

Jack

Good thing he had the forward titling canopy.

 

He also had a female passenger with him. Was it Jeanna Yeager?

Your absolutely correct Bruce. Shirl was in a air race at the time with Yeager as his passinger, very close call. Another possive for the forward hinged canopy.

 

Jack

I think Spencer's is based on a Ford engine. Direct drive. Don't remember the details on the Buick eRacer except he had a lot of issues.

Sencer's Ford is a 351 cu in direct drive V8. Shirls aluminum buick V8 had to the best of my knowlege 750 hrs on the engine. the only mechanical problems were a broken rocker and a rod, neither contributed to a glider situation. That being said, he had a cowl fire because of the exhaust exiting the side of the cowl and almost lost the AC.

 

Jack

Best of luck in your new venture Tony.

 

Jack

And a lot more help than I get.

 

Jack

Oh crap, thanks Tmann, now everbody knows.

 

Jack

The one I had was an overkill.

My blended winglets are at 6in inside radius at the center of the spar. That radius changes as you move aft of the spar.If you make the radius any larger it would saise the rudder up to far. I would never install a blended winglet for anyone other than what I have personally tested. I do not recall that the radius for the winglet was ever brought up. I'll go back tomorrow and see. The out side radius is close to 12 in, but not quite. I loaned the template to someone and never got it back. There is a loss of attachment at very low speeds with this blend but does not have any adverse handling qualities and I gained between 10-11 kts at speeds from 130 kt to 210 kts across the board.

The new ones should be interesting.

Jack

There are a pair of partially completed VE for sale on barnstormers.com, experimental tab. Very reasonable.
