What is air racing ?

Re: What is air racing ?

Wardrobe racers... After your ref to storage,

JRP... Juke Race Planes

AM... Air Midgets or Minis

AFR... Affordable Race Planes

Pocket Racers...

I do like the TB as well, just throwing out some more.

IMHO; It is a mini..or micro...midget and wardrobe racers sound little outdated.

What about 4 x jet turbines ?

And what about 250-260 mph with 4 jet turbines in a Tweedy ?

The song on the background is MODY's - Natural blues ! Really cool vid too.

Here it is !

Be gentle on the comments...this may be my first AC that I ever build.

best regards,

Re: What is air racing ?

Kinda looks like a premie Pond Racer. Pretty cool and more power to ya Juke!

Where's the "lifting body" and the great ground effect?

Koha,
Why do you have to bring these attacks here? If you have problems with Juke, well ridicule him at your sites, WE DONT CARE WHAT YOU THINK. get it?

Wayne, ban Koha his only two posts are attacks against a member in good standing.

Re: What is air racing ?

I agree,he should be banned or at least toned down,they never thought a lot of Rutan's designs would ever fly. Enough.

KOHA... check your PM's...We like to keep the atmosphere pretty smooth here.. The members have spoken....

consider yourself warned

Juke;
Keep drawing. I love your creativity, Passion, and Direction. I will throw down another 1K to the award fund and test fly your concept if you need. I will also help build components for you if needed. "Lets Go Downtown" as once said perfectly in "The Flight of The Intruder".

PS. To those of you all that can't see the woods for the trees, please take a chill pill. This was not about anything other than a great idea.

KOHA is OK with me, Spot on... or spot off... Opinions are great. "Kick the Tire, Light The Fire!"

Re: What is air racing ?

Where's the "lifting body" and the great ground effect?

They are all there as promissed..I kept repeating this is not a lifting body AC and this is no ground effect plane...it just uses those effects into certain extent. In order to gain advantage over conventional designs with normal landing gear.

In Finland people are used to pay millions of good planes and cars...never invented any themselves...thence this terrible noise...anything new is considered ugly and offensive.

What we have invented so far is one ground effect vecihle and engine mod for a motorglider ( Pik-20E had a plug added to 2-stroke Rotax 20+ years ago ). Othervise it has been copying of some previous US and European gliders and motorplanes.

But who knows..we might do one invention that flies...pretty soon as people gets they act together and start behaving. Not to mention we might need some money to do it as well.

I will incorporate a big change into Tweedy still..in order to gain more downward visibility from the cockpit ( now 8-9 degrees down..Reymar suggests 11 degrees ).

I got a feeling those 32 hp ( 300 ccm 6 cylinder boxer ) engines can be tuned to 100 hp for few minutes..so we really need no more power for a plane this size..on the contrary this will fly with 2 x 17 hp engines as well ( 150 ccm ). Possibly with two Evolution 115 ccm model engines too. The cheaper to build the less hp:s the plane is designed for.

Thanks for the promissed help. First I am gonna meet a dude who has actually designed and build 2 AC:s ( ultralites ) and other has Aixro wankel engine on it. He lives only 100 km ( 60 miles ) away south from here. So stay tuned.

Gotta run to keep the family fed !

C'ya later !

I am not 100% happy with this sentence.

I rephrase it.

We have outstanding gliderdesigns like Kajava, Vasama, Utu and Pik-20 + motorplanes Keltiäinen and it's never version Mini-Sytky and few ampfibians + 2-3 glider towplane designs ( + miscallaneous experimentals and military trainers and few fighters ) and one sports plane Viri, but none of them were revolutionally new like Tweedy-Byrd...which also is just a mix of Cri Cri, Thunderbird II and my R/C design Phoenix from 1990...like someone said nothing new...but the design itself and its landing-gear system.



PS: Here are all ( most ? ) finnish AC designs so far.

I hope nobody managed to inhale a pea into his/her breathing organs of my earlier comment.


Here is Keltiäinen that was a record setter:

Re: What is air racing ?

Juke,

When you get over to the wankel powered plane,
how about a picture report for us ?

A few lines of stats would be nice too.
You could be our Northern Europe reporter/advisor!

.......I have some concerns on the madel aircraft power plants
(yes they are nice in many ways,just very highly stressed).
But I do believe you will find someting suitable (with a continued search).

Re: What is air racing ?

Sure thing Jim,

I ask first if it is ok to take and publish pic. He has a pump installed in it and removed that old Briggs & Stratton V engine of some 30 hp from it to replace it with this Aixro.

His earlier design ( Amfibian U376 or something ) is in the list / link I gave his name is Vesa Pehkonen and metel engineer by profession. An other real aviation engineer will be commenting on this project soon as I applied for a statefund for developing this AC..he will evaluate if there is potential in this..this might be hard because even aviation officials seem to not see the benefits.

One thing occurred to me..if the props rotated into different directions...it would be a great asset...Tweedy would perform a lot better if the props turned opposite directions and particularly left prop clockwise from the pilots view...and right the opposite...this would create a better cushion around the fuse and eliminate torque of any kind. Also controls would react evenly. I wonder if that is possible to do ?

You can do it with the PSRU's (if you have to)
(look at torque curves/revs of engine vs prop dia)

......Juke, there is a lot of "homework" to do yet before I would present this design for a grant/subsidy.....
...........I know you can get it done.
