I can vouch for the wonderful design and engineering that Chris Heintz d=

id on the 801. When I floated my desire to install a V-8 Ford in my 801 =

all the guys at the ZAC kinda wished me well but none expressed any real=

 doubt of the results. Now after reaching 100 hours I am sure the airfra=

me is more then strong enough. It shows absolutely no signs of deforming=

 at all the attach points. The two real things that I fought through the=

 first few hours was...

1-     Trying to keep the beast from overheating,... I have attributed t=

hat to the fact that the 801 flys sooo slow the actual ram air pressure =

going through the rad and oil cooler was not enough to exchange heat to =

the airstream. Those issues are in the past..

2-   The one area that almost bit me was taking off with full flaps and =

full power. I have a 0-150 mph airspeed indicator. I once tried to keep =

the stick all the way back and let it fly off. Just as the needle came a=

live, somewhere about 28 mph, the plane lifted off. Because of the rathe=

r large  prop blast the tail feathers work to a degree, the real problem=

 is that the flaperons when fully deployed are not effective at that slo=

w of an airspeed. The plane torque rolled and tried to hurt me !!!!!!!! =

 Needless to say I will not repeat that stunt again, I will not rotate t=

ill I see at least 35 mph now.  With that all said, I LOVE my 801 .!!!!!=

That's great news. I'm heading to Cloverdale, CA this weekend for the Qu=

ality Sportsplanes Fly-in where I hope to see more. Florida is on my lis=

t.



My 701 will not be standard. I've hesitated to post this due to response=

s like you received earlier, but I'm actually building a 701 at 110% of =

stock dimensions and using a 601 firewall, just so I can use the Corvair=

 powerplant and go for 1320# gross.



Now, before I get flamed, I spent two months reviewing the standard 701S=

P plans and reviewed every on-line 801 drawing I could get at Zenith's s=

ite. Only then did I calculate structural and material changes required =

to get a little more interior room, the higher GVW and the ability to us=

e that lovely Corvair powerplant.



I submitted 2 pages of proposed modifications to Chris Heintz for review=

 and other than a suggestion for a .032" HT spar material thickness, my =

plans were approved. Mathieu tells me that my proposed mod's are very si=

milar to the working calcs for the briefly mentioned CH750. And sorry, n=

o, I won't share my changes with the open community as I don't want to b=

e on the hook for anyone else's skin but my own...



I'm glad to hear that William is giving it a go with the 701. His relati=

onship with Zenith and the Heintz family can only bring good things for =

all who are appreciative of the harmonious ZenVair. =

Those who don't care for this combo are welcome to continue flaming away=

. We consider the source of all of the prattle that can fill these board=

s. To each, his or her own, and may everyone enjoy this amazing hobby.



Thanks again to everyone in this community who have so freely shared USE=

FUL information with those of us who have chosen to LEARN, BUILD & FLY.
