Posted: Sun Oct 15, 2006 5:41 pm Post subject: Model V with O-200; questions

Anyone out there flying a model V with an 0-200  continental 100 hp?  A friend of mine just bought one like this and reports  a 85-90 mph cruise speed and a 400-500 fpm climb rate.  The airplane is 900  lbs empty and is equipped with a Warp drive prop.  I have a model 6  specs page that shows a 120 mph cruise and a 1200 fpm climb rate.  I  realize the factory numbers might be somewhat optimistic, but are they that far  from the truth?   Or is the warp drive the wrong prop for this  engine and airframe?

Does seem a little behind in performance. I have a Model V with EA81 T 

72"Warp drive and guess it's around 120HP. I get 1700fpm at 60kts with just 

me on board and 3/4 tanks. Mine is a heavy beast - 945lbs.

Paul  

I’m flying  a VIXEN model V  with a 0-200 continental 100HP and my reports is  the following : cruise speed 100mph, climb rate 300-500fpm with 70mph and 3000’’feet with 10000’feet the climb rate is almost 50-80fpm . Prop warp drive 70”, static RPM 2600 elevation 2000f.  I’d like to get the specs of the factory.

Francisco;  

  

 Interesting specs.  Much like what my friend is  experiencing.  Here is a copy of the specs sheet page for a model 6 Kitfox  (along with the IV on the lower part of the page).  

  

 I wonder if a different prop, say one from a 150 Cessna  would improve the performance?  Have you ever tried a different prop on  your Vixen?

I can't speak for the factory specs and I tend to  agree with what you say in that they tend to embellish them.  That being  said, your reported cruise/climb speeds for the 0200 are definitely low.   Something is seriously wrong there, but then again, drag reduction is a pretty  big factor, especially with the struts.  That doesn't explain the poor  climb rate though.  Possibly the engine isn't producing rated  power?

Francisco,

  

 You  never said what rpm you are turning .

 I  am assuming this is a landplane ? 

 If  on floats and at 100F   then I appologize. 

  

 Is  this a new engine  install ? 

  

 Dave

I have never tried a different prop. May be would be better another prop like a Sensenich

Deke  

The engine today is only 300Hrs of fly and has all struts checked may be I thing the poor speed and climb is for the motor weight. I spocke with the factory about this 5 years ago and they told me that the all the planes  are not identity.

I always flying  with 2550Rpm, the plane only has a 300hr of fly. And we installed the weelpants  

Thanks

That 100hp should pull the airplane faster than  what you indicate so assuming the airplane is well fared and the engine is OK,  then it's entirely possible that your problem lies in your prop selection.   Maybe calling Sensenich again and talking to their tech support might give some  insight.  My S5 with 100hp Subaru cruises 108 at 3900rpm and a typical  climb is somewhere around 850 to 1200 fpm depending on temp and load.  One  thing I do have that is different from you is an electric cockpit adjustable  prop (CAP) which may account for the big difference.  Airmaster makes a  nice unit, but I don't know if they make one to fit on an 0200.  http://www.airmasterpropellers.com/wa.asp?idWebPage=3672   Personally, I'll never have another airplane without a CAP.  They're  especially nice when on floats.

 Good luck,

 Deke

Francisco,       your 0-200 only gonna be giving you about 80 hp or so at 2550 ...... at  best on a perfect engine 

  

 You should see  2650 to 2750   for take off  , so basically you missing at least  20 % of your performance there alone .

 So for  example........ 

 If you  see  800 fpm  you missing at least 160 fpm  so that brings you  back closer to 600 fpm  

 Has the  compression been checked in this engine ?  And is this the prop that warp  recos for this engine /airframe combo ?  It would be a benefit to give them  a call  and maybe you just got to fine up that prop a bit to get higher  rpm.  

  

 If you even  flown a plane then change to seaplane prop  that alone will tell the story  on performance gains.

Paul

 I have  a series V with a 0-200 , Cruise at 115 MPH at 2400 RPM ( i don't like to  run  at 2550 ) get about 1000 FPM climb using a warp drive 3 Blade. My  empty weight is 860 and my motor is at about 1/2 life 700 hr's on it, and if you  are to use the warp drive you should find that it is very smooth and a lot  quieter IMHO than my  2 blade wood prop.
