Taurus flyer,
I just receive the plans to build a Ed Kazmirski ''Taurus''. A question I have for you is: The original Taurus was equipped with a .45 engine (Veco I believe) you have mentioned yours has a ,61. Does it need all that power from a .61? Would a .46 be enough?
I have both, I was just wondering why you selected a .61.
Your Taurus looks great. I plan to finish mine same as the original also.
What is/was reason for the brakes on the landing gear? I saw them on the plans and could not figure why they would be needed.

About the Taurus,
Engine
First Taurusses already did fly in 1961, Ed Kazmirski did start design the first Taurus probably already in March, April 1961.
In that period the K & B 45 RC was very popular and used on scratch built Taurusses in 1961 and 1962.
For that reason we see the outlines of the K & B 45 RC. on any plan of that period (Picture 1 and 2)
We see a Veco Lee 45 RC used by Ed Kazmirski in April 1962 on the first commercial "Top Flite" Taurus.
During the world championships in August 1963 in Genk in Belgium we can count 12 Veco 45 RCs on the 17 Taurusses (see picture 3).
We also see the first 0.49 s on the nose in that period.
THIS IS ONLY A RANKING LIST OF THE TAURUSSES, THERE WERE 39 MEMBERS AND PLANES TOTAL. THIRD PLACE WAS FOR ED KAZMIRSKI.
The Taurus is designed for the 0.45 so that’s the best choice for classic pattern flying to keep the weight low.
My Taurus always does fly with reduced power, only in vertical maneuvers the 100 % is used
The plane is also heavier, about 4000 gram and with that wing loading and power I also can fly with stronger wind, even 6 beaufort is possible!
Wheel brakes
In the past two maneuvers of the pattern program you did have to make “on the groundâ€, “Proto taxi†before and "proto taxi to hangar"after flight. See the picture 4
For this maneuver the planes have to be designed to taxi and turn and stop on the runway with idle engine. For these maneuvers the brakes were needed.
Designed to taxi? Yes, think about cross wind, while turning!
So 0.45 , because enough is enough, 0.60 you can use and the brakes you can mount them if you have to make the proto taxi maneuver. I use the brakes and can stop the plane on a relative short runway, even if there is no nose wind. You must reduce the speed to turn to keep the three wheels on the runway.
BTW In my thread “Redesign and reconstruction of the Oldest Taurus on Earthâ€, in Classic Pattern Flying of RCU, I do show the rebuild if the first Taurus of Ed Kazmirski, the result is shown in picture 5. The nose wheel brake isn't mount yet
http://www.rcuniverse.com/forum/m_7950207/tm.htm
Success with your Taurus, you will be happy with that plane but remember when turning you must reduce the speed to keep the three wheels on the runway last picture.

plcline67, I don't know if it's just me but it seems like you have your canopy on backwards. Otherwise, looks great!

RE: post some pictures of your pattern plane!!
I agree, but it was built when I bought it. I tried to remove the canopy but it's been glued on and removing it without doing damage is going to be difficult.
Anyway, this is my first pattern plane but I love how it handles. I'm still at the "beginner" level as far as my flying goes but this plane is a blast! I can't wait til I'm good enough to actually fly it like it's designed to fly! I'm sure I'll get another pattern plane in the future. And I'll make sure the canopy is on the right way!

My baby is just about to be finished...Her name : Stratus
Own design, not the best, but MY best, what makes me feel so happy!
Will be powered by an OS 160 !

Hi
Time to get this tread up in the front again I think , always nice to see others planes.
Here is my new Xigris C2 ,hope to maiden tomorrow after work , weather looking promising !
So fare weight is just under 4800gr
powred with Neu controlled by a Castel HV 85
Radio Futaba with bls servoes on rudder and elevator and futaba 9551 on ailerons
Batteries flightmax

Claude:
Thanks very much for the plans. I had them printed at the local printing shop and the plane is absolutely huge (about 1300 sq inches and a 2 meter fuse). The airframe looks to be very nicely designed. I am looking forward to the construction process.
Thanks again,
Ed

Hello
Maiden flights done this week with my second Harmonie.
Engine YS170 CDI, prop APC 20x10.5, fuel 6 % oil, 20 % nitro (with this fuel only 6 % oil, plane is very clean after flights).
Before and after

RE: post some pictures of your pattern plane!!
here are my two Magix That I have build this year ; the pink one is 40 flights and the green one is 80 flights ;the two models are powered by 170 cdi and 19/11 propeller
they are fully moulded composite under vacuum;
fuselage is glass, balsa , glass and a little bit of carbone; wings , stab and rudder are glass, herex, glass
weight with the 170 cdi is 4930g
I build also personal soft mount and landing gear

May be Ugly in your opinion, but the flights are aero magic !!! and knife loops are so easy

RE: post some pictures of your pattern plane!!
I have decided that as I grow more mature (read older [sm=49_49.gif]) my flying skills have diminished and that since I can't fly as well as I would like [sm=spinnyeyes.gif], I decided to try my hand at designing. Attached are a few photos of my own design 2 meter pattern plane. Wing area is 1054 sq. inches, span is 76 inches and length is 76 inches. Power is OS 160 with Lorenz header and ES Designs carbon pipe. Flying weight is 10 lbs and 14 oz. I have approximately 35 flights on it. I have a version 2 I will start over the winter which will incorporate changes I want to make to the plane (length, wing area, weight reduction diet, etc.).
