Hi  Bob,

I am mostly interested in wheel skis.

Hi Bob.  Thanks to your reply on my airbox question.

Firstly, I had a look through your photos and I'm impressed.   The engineering mods you have incorporated look very interesting indeed.  Skis and floats!   We have a local 701 owner who has a set of floats but I haven't seen skis before.   The aerofoil roof panel is interesting too.  One of our local 701 guys has just done his and claims a 4-5 knot increase in speed.  Myself and another guy are looking to do ours soon too.   The wingtop fences are interesting.   Are that associated with the skis and floats, or some other aerodynamic aid?

Now, the airbox.   Would you be able to send me some photos, as it sounds like you might have already done what I want to do.  I am buying a new Rotax engine for mine (although the old one has only 250hrs, it is an old one.  A local guy is going to buy it for a good price, but there is a whole new topic)   Anyway, if I buy the Rotax airbox at the time of engine supply, I can get a sizeable discount, although it is still expensive at $1250.   I'd like to see how you modified yours and that might be the way to go, as opposed to making one from scratch.

Secondly, great photos.  Reminds me of much of our own flying ground here in the South Island of New Zealand.   We have about 6 701s here and we go flying on Saturdays along with guys in Savannahs and Foxbats.

I have a 914 but I will check the intake mount points to make sure they are isolated on the engine side.

Black Bear went through my 4 ft X 8 ft kitchen window of my Northern Quebec camp last week. I'm still looking for the bear. A Timber Wolf was coming around my camp 2 - 3 times a day... close a 30 yards, 3 warning shots the 4th a kill. I'm carrying a rifle around the camp these days also. Never had a bear problem in 35 yrs, this year a bear & wolf.

My name is keith. I am building a 750 cruzer in kenai. I am seeing how many Alaskens would be interested in having a zenith builder/flyers get together. If your are interested I would like to get your input on time and location.
Thanks for your time.

Hi Bob, I was at Zenith last week and requested a drawing to attach two strap seat belts to a 701. They asked me to contact you. Last year a friend crashed his 750 and slid out the standard belt setup causing him severe damage which could have been avoided with a two belt system.
Thanks Temos

I will bring my plane to Anchorage the end of April. We can get together then. Let me know of any requirement that I may need to follow.

Hi Bob,
Thanks for clarifying for me... I know and love the 701 performances just wondering why another 701...
Have fun.

HI Bob,
Why a 701 again??? Why not a 750???? Same engine same design just more room!
Merry Christmas.

Good to hear your comments... a few year late about the cowl tank and 5.5 gal wing tanks. This is what I have been thinking about. No sender units, simple fill for normal flights and extra capacity if you need it.

Hey Bob, Thanks you brother, I do have the VG's on the stabelizer, good to get these kinds of tips from experienced 701 pilots, Thanks again

Bob, There is a video on the Zenith website doing what you said about the front wheel. Thats what changed my mind about the 701. I will save the tailwheel for when I build a Pietenpol some day. But for now I need and aircraft that can be built in a 400 to 700 hours, can sit outside and can takeoff and land in a cow pasture without being damaged while being easy to fly.Also, If need be I can add floats and use the Ohio river for a runway. The CH701 was designed to be a nose wheel aircraft unlike a J-3 cub or Pietenpol which where designed to be taildraggers and fly will as taildraggers.Those airplanes would not fly well as nose wheel aircraft.

Hi Bob,

What engine are you using in your ch701. Does Zenith still sell the planes for the skies.

I'll check the website.

Hey Bob, An honor to be your friend and to be part of the 701 community.  Your wisdom and knowledge is highly respected.

Hey Bob, do you think you can tell me where you got your skis for your 701 from? I've been looking and havn't found any, and if you built them from scratch would you be able to give me some design patterns if possible? thanks,
