    Bob,

    Would you care to comment, or elaborate on the three protrusions that are seen on the top of each wing in your " Extreme water take off demo ". They look to me as being some type of fences ( for lack of a better word ) that are often seen on certified STOL retro, kits that are sold by compagnies like " Robertson STOL "

    Are these " home made modifications " to your 701, or something that can be found elsewhere, and how effective have you found them to be. ?

    regards

    Robert

    Two things I would like to pass on to other builders, 1. put the key switch in the center of the dash , so you can operate it with your arm resting in the -y- stick. this helps with restart in flight , taxi on floats ,and ski's as nose can be held up with hand also on key to shut off when coming to the pier or shore ,while holding throttle with left hand. 2. DONT use a plastic fuel filter under the cowl, and wrap insulation adound the metal filter for fire protection , and vapor lock prevention ..VERY important...

    Hello Bob,

    Thank you for your prompt response. :o)

    I have already purchased the VG's for the elevator, and I am very impressed with your water take off's not to mention the flight attitude of your 701 in the recent video on skies.

    I also agree with your comment about the fences looking really cool, and was wondering if you happen to have any close up's of the fences, and the method you used to install the horizontal stabilizers on the tail. If you do, would you please send them to me off forum at the following address

    robert.pelland@cgocable.ca

    Thank you for the time you will take to address my concerns.

    You have my very best regards
    Bob

    ATTENTION BUILDERS ! I now have a new 701 kit, and will start the build in the fall, I ordered my new plane with the "old style" 5.5 gallon tanks to use as auxillaries, Zenith as always accommodated and remade the tanks. It would be to any builders advantage ,to do this . It gives you almost 2.5 hrs. of added fuel , and by design [ ie. against and parallel to the strut] almost on the CG. ,so no weight shift, the aux. tanks can feed the mains and therefore do not need fuel gages, sure beats gas cans for the long occasional flight ..BOB

    Hi Bob
    The angle of incidence on these floats is 4.5 degrees with floats level.

    Hello Bob
    I live in Newfoundland and we have lots of snow..Would appreciate
    a copy of the plans for the skis for winter flying.

    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,

    Brody

    Hi Bob,

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

    I'll check the website.

    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.

    Bob,

    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.

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

    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, 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

    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.

    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.

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

    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.   

    Regards

    Buzz
