As a few know I'm the one who  has been asking about the HKS engine (700E).  I definitely won't be  replacing my engine for at least a year.

  

 In the meantime I'd like to  clean up the plane a bit. and the first thing I noticed was the rad hanging off  the belly.  This must have the aerodynamic stability of a brick or  less.  

  

 I have noticed on some of the  pictures here that some of the planes have what looks to be a very nice scoop  mounted to the belly of the plane and could offer a streamlining effect,  directed airflow through the rad and possibly even offer a damper of sorts  for winter flying.  I haven't seen anything like this scoop available  on line and such a scoop isn't mentioned in my construction manual.   Building a mould to fabricate one scoop seems kind of  expensive.

  

 Three   questions.

  

 Are these scoops  available?

 If they are   where  do you get one?

 How much will it  cost?

Building a one time mold isn't expensive if you  just use typical one inch blue board foam then cover it with glass.  When  it's set up remove the foam and you have a scoop.  It almost requires the  airplane be upside down though, but when the wings and engine are removed it  isn't too difficult with Somme help.

 I'm going to attach a photo of mine.  It's on  Sportflight, but the site is down temporarily so I can't send a link.  I'll  try an attachment.

Noel,



I have the scoop offered in the Model IV Speedster kit.  I picked it up from 

a builder in Alaska that didn't want to use it.  Others have gone the hard 

way and built their own.  I don't think the Speedster scoup is still 

available.  Contact John to make sure of that.



Regarding winter flying, the scoop actually enhances cooling.

Noel-

I've got a scoop from my IV that I'm not using. It's yours for the  

postage...or actually I owe Deke a lunch for an owed postage deal, so  

you and he could... oh, never mind...let me know where you are.

Hi Lynn, How much speed would you gain by adding the rad scoop that was  available from skystar.  Jim

Noel,

   

  You have a Model 2, right? As slow (Vne 100) and draggy as the Mod 2 is, do you think the extra weight is justified by the extra couple cruise mph you're likely to gain?

It is a very draggy Model II...  very late numbers (736).  It is on a nice sleek set of Aerocet straight  floats.  As I was saying I've been doing a bit of work on the plane  the past few days and would like to clean it up a bit.  Also dragging those  floats up hill does require the engine to do 1quite a bit of work.   I  thought I could install some kind of shutter in the intake of a scoop to cut  down the airflow through the scoop in the winter.  To be honest an extra  mile or two per hour really doesn't interest me too much on this kind of plane  but if I can improve the cooling efficiency in the summer and control the air  through the rad in the winter I think it will be worth it.

  

 I am also considering trying  some plastic fairings on the wing struts.

  

 It seems there are a few of  those scoops around and several of them are on planes.  I'll post some  measurements and see what fits.

Thanks Lowell.  I expect if John has one in stock he'll post it.  That way

if any one wants to install a scoop they will know where to get them.

Beats me...I'm aircooled, so I've never looked into the scoop  

situation. But this (the one that I have) is the one that Skystar  

provided.

Great!   The next questions are how heavy and how much.

I purchased one from Skystar.  I would think the new Kitfox would have them available.
