European part 103 very fast low wing plane
« on: July 11, 2017, 12:15:02 AM »
Hello,

i found the SD1 from Spacec. Its a low wing plane with 137 mph speed and a 33 hp 4 stroke 2 cylinder V engine.
Maybe is interesting someone.

There were a couple of kids trying to sell the "bird kit" at OSH 15-  kit only and at somewhere in the $50K range…   Tuff sell it was… I did not see them at 2016 (could have been there) and see someone is going to try again in 2017.  The design work and thoughts seemed to be excellent, the ability to build at low cost did not seem so much.

Always nice to see some new designs.

First i want to say there is no question, the LE is a wonderful machine and a totally different thing than the SD1.
But i want to fly a little bit faster than LE and similar planes. Im thinking about to use a faster airfoil for the LE so the cruising speed raise to about 80 mph. I know it needs some stronger building.
I saw a J3 Kitten Reliant build in Italy, empty weight 395 pounds, with Rotax 582, cruise speed 85 mph, VNE 100 mph, spoke with owner and he said there where never signs of flutter.
i dont know if that is possible with the original airfoil Goettingen 387, see here: http://airfoiltools.com/airfoil/details?airfoil=goe387-il

I had the opportunity at Friedrichshafen 3 years ago to see the plane live, the german seller was there with his own SD1.
I think building it from plans compared to a LE probably takes 150-200 hours more but not cost expansive.
This is only a european (Germany) phenomenon because the admission rules are very strict and you need perfect soldered metal pieces and so on...
I live in italy and there is not so strong to meet the admission.
Anyway i think it depends of your building skill and what you can do it yourself.
Probably i can built it with 500 bucks more than a LE.

  the plans available?   I don't think I could get plans in the USA, but could be wrong.
If your figures are correct, that would be a great little bird for the time and money spent.
I guess I have not searched for a forum on the SD1, but presume one is out there.

I understand now what you mean... its a must to buy from them the basic kit, that include the composite wing spar.
This Kit the german seller sells at around 1000 €.
