After I fitted out the mains on my stock CH 701 with 21 800X600 Tundra tires from Dresser I immediately knew that something had to be done to level the plane.
First I extended the stock nose wheel fork two inches at the axle and used the golf cart tire as supplied in the kit which worked to get the nose up...a little. Still didn't like the thin walled golf cart tires.
Then I knew that to do it right I needed to add the 21 800X600 tire on the nose. By pre-planning and luck it all fits. (the more I plan the luckier I get !! )
I attached three pictures one shows the plane with three 21 inch tires and two show the modification to the fork. I posted an article about the nose gear extension in another area.
Where is your article Phil? I don’t see your pics
Sorry folks - the narrative came through but not the following pictures
Kinda still grinnin
How much did it slow you down?
The plane I built is used out here in Idaho and mostly cruises in the four thousand to six thousand foot altitude range I built it as light as I could - no extras, full five screen glass panels, heavy interior options, paint etc. Original weight and balance was 594 lb empty - probably ten more pounds now with the larger tires etc. Went with no tubes to save weight and all has been well so far.
Take a look at my pictures to get an idea of how sparse the interior is and also did not paint to save weight. Used the methodology of - threw it up in the air and if it came down didn't put it in the plane.
Most days I see 90mph true in flight and on the ground at 5300 rpm. Rotax ULS with warp Drive three blade set at 13.5 degrees. I did not see a noticeable drop in speed when I put on the mains - after the nose tire MAYBE a couple of mph but luckily I don't care.
Did it slow me down - probably - but I don't have the instrumentation to tell. If I was that concerned I Would add streamlined strut covers. Hmmm???
Didn't build this for speed just to dink around; hope this answers your question
