Just to update all of you that are tweaking your CH 701 and possibly your 750.  These mods probably don't add speed or short field capability - LOL - but were done to clean up the original construction.  First of all go to "my Photos" so you can see what I am talking about,

I never liked the bubble door to front post fit that I created in the original build it was noisy and drafty especially in winter. So the first item was to build new trim strips for the front pillar to windshied junction.  If you look closely you can see that I used a 50mm wide piece to fab a new trim that allows a surface for a foam strip to positively seal up the door.  Also added a break to the leading edge to keep the strip from warping along it's length. Works great.  Now all I am going to do is add the "boat type" knobs (the idea was offered a while back to keep the door positively closed)  to form a lock to keep the whole thing tight in cruise flight AND when my knee "leans" on the door a little.

Next, I never liked the "flat" 20 mm trim over the top of the windshield so fabricated the " new" part to conform better to the front and rear.  Also extended the trim to smooth out the air flow at that junction.

Where am I now in the CH 701 experience?  Rapidly approaching 100 hours of outstanding fun and satisfaction.  I was asked if I'd build the CH 701 again...thought about it and said "No I'd build the CH 750 for a slightly more capable plane...but I have loved every minute of flying the CH 70Funderful".
