    Don't dump them, Larry! They are excellent pictures and the site has lots of storage room.

    Great shots. But there's still ice up her for Dave Lima and myself.

    Hi Dan:<br /><br />Ok, I will leave them on. Many thanks.<br /><br />Best,<br />Larry<br /><br />Hi Lee:<br /><br />All the small lakes are still ice-choked down here as well. The Grand River is open but of course is a torrent (spring run-off). At this end of Lake Ontario, most of the ice has cleared out, although I did see the occasional small ice pan this morning. Delightfully, most of the ice bank along the shore has also melted. Come on SPRING!! (g)<br /><br />Best, Larry

    Great pictures of a great looking plane Larry. We leave Baja in 2 weeks so hope to have VMU in the air by the end of April. CU then.

    Larry<br />Just flew over the Elmira Maple Syrup Festival in a brisk wind and 2 C. A quick shot up to Conestogo Lake revealed the ice covering to 40 % and broken up, ready to leave. Dave Lima's field was tempting, but a low pass is all I could do. It still too soft for even John Dunlop's soft landings. The Cherokee gave it a pass at 'high' speed.

    Lee, you can land the field is fine, just buzz the house first and I'll come down and pick you up. <br /> I wanted to go out today but it looked quite windy for a searey.

    912S?<br />How is perfromace -puller vs tractor?<br />Variable in flight peech control-reccomended?<br />3 seater?

    Hi Ed:<br /><br />- My A-24 has a Rotax 912-S installed. It also has a cockpit-controllable, variable pitch prop (KievProp).<br /> <br />- I have not yet had a chance to fly it against an A-24 with a fixed pitch prop so I cannot provide comparable data. I suspect that the variable pitch prop does provide some mild performance enhancement.<br /> <br />- While I personally prefer a tractor-configured situation, I don't think it makes much difference in performance. The benefits of the tractor configuration to my mind are:<br /> the prop does not experience damage from grit or stones coming off the main wheels when landing or taking off.<br /> the prop does not experience water damage created by water spray coming off the hull during water landings or takeoffs.<br /> One does not experience the typical 'throttle-up-nose-pushed-down' (nor the opposite) situation found in some amphibians.<br /> <br />The negatives are that the engineering required to properly distribute the engine loads are more challenging in a tractor-configured amphibian (this has been well done on the A-24). As well, if the windshield is not well angled, one could experience heightened noise due to 'prop-beat' against the windshield. Again, I have not found this to be a problem in the A-24 but I am looking forward to the opportunity to actually measure this parameter in a professional manner. <br /><br />Performance:<br /><br />- The empty weight of my A-24 is a hair over 1,000 pounds. Its useful load is around 650 pounds. The CG is quite benign as far as loading is concerned.<br />- It is a true 3 person aircraft, but of course one must pay attention to W and B when three people are loaded.<br />- It carries 23 US gallons of fuel in wing tanks.<br />- Takeoff roll is remarkably short. It gets off the runway or water faster than other amphibians that I have previously flown. <br />- Stall is 49 mph dirty and 54 mph clean<br />- Climb is 600 to 800 fpm depending on temperature and load.<br />- Cruise speed is 90 to 95 mph and top speed is 105 mph.<br />- Like most low-wing-load, high-drag aircraft, it comes down fairly quickly with the engine at idle (or heaven forbid, stopped). The full cowl and absence of flying wires does suggest that the total drag is probably quite good for an amphibian. <br />- It has plenty of room in the cockpit. (not a performance item but still important to most pilots). (g) <br />- I have not had an opportunity to perform landings and takeoffs in 'rough water' yet, but it seems quite forgiving of water landing errors. (g) <br />- On concrete, the high 'Tee' tail and lengthy distance from main gear to tail wheel provides a bit of added momentum, which can keep the pilot busy in cross winds. I am comfortable in full cross winds up to say 10- 12 mph and have done a few in higher cross winds, but I sure had to work hard and will likely use 12 mph as my personal limit for a while. The rudder has plenty of power, but the aircraft does sport a high aspect ratio (long) wing, which means that cross winds have to be respected. <br />The aircraft is extremely strong. It will not have structural problems with any form of normal useage.<br /><br />Hope this info is helpful.<br /><br />Best,<br />Larry

    HU Larry, the traditionnal question......the price ???? and how much time building compare with Searey...? And compare with the 4 places that PA will show at Oshkoch.<br />Many questions hein....<br /><br />The melting point has begun at my place, just a little near the deck... if you concentrat you might see... YESSSSSSSSSSSS.........<br /><br />Bruno      Attachments:

    Bruno, don't hold your breath on the 4 place searey being at oshkosh. Your dock looks nice and cold, more snow coming on Thursday.     
  
Bruno Grondin - Apr 03,2007   Viewers  | Reply
    I know, but still want to know more about it, Kerry told me that they where (SUPOSE) to fly it to Oshkosh this summer so... And yes the dock is cold...hahaha<br />Se youa Dave...

    Bruno - the big Searey has been almost ready for the 3 years I was building...     
  
Bruno Grondin - Apr 03,2007   Viewers  | Reply
    So will it arrive one day...?     
  
Larry Woods - Apr 03,2007   Viewers  | Reply
    Hi Bruno:<br /><br />We have done everything possible to keep the price below US$100,000., which has been our 'target price' for some time. This 'target price' includes the Rotax 912-S as well as the variable pitch prop. I will be able to provide more info shortly. Certainly it will not be far off this price one way or the other.<br /><br />I am estimating 350-400 hours to build.... and this for the guy who has never constructed an aircraft previously. Keep in mind that this is an approved 'Quick-Build' kit in which several sub assemblies are delivered finished and painted. It took forever to make decisions with respect to my 'Quick-Build' submission, as there are all kinds of 'trade-offs' that one can make. I do think that the adopted strategy, which was to have the factory build all the difficult sub-assemblies (especially where alignment is important and where the factory's high cost jigs and fixtures could be utilized to save time), will pay off for the builder in reduced aggravation. <br /><br />I will be taking delivery of the first kit this July or August and plan to build this one in my own shop. As this is done, I will complete the builder's manual and also a video (I hope) relating to the step-by-step building process. I want to ensure that we don't leave any nasty problems for the builder to overcome ('been there and done that' in spades with my Questair Venture activities). From day one I have maintained a 'go slowly and carefully' perspective on this project and have no intention of changing this approach as I complete it. By next year, we should have the kit building process fully proven and with documented building hours.<br /><br />This past fall and winter, I have spent much time testing the A-24 in a broad variety of conditions to ensure that there are no serious inadequacies in the design or construction. There is still more of this to be done, especially with respect to rough water conditions and additional flying with a third person on board. Of course Aeroprakt has done all of this kind of extensive testing over the last few years in central Europe, but this is the first A-24 to meet up with North American conditions and North American pilots. To this point in time I have invited several local veteran pilots to fly with me in the A-24 (left seat, but with yours truly along in the co-pilot's seat) and have solicited their thoughts and perspective. As one might expect, there are things that some do not immediately like because they are different from what they are used to. Then again, I have received some darned good ideas from a few pilots that I missed as a result of being 'too close to the forest to see the trees'. The good news for me is that every pilot who has flown the A-24 has gone away raving about it and delightfully, we have found very few things that need to be changed. Those changes that we recommend to the factory are typically incorporated into the design fairly quickly. Of course, I don't win on all of them. (g)<br /><br />What I can say without reservation is that this whole 3 year experience has been a happy one for me. The A-24 performs beyond my expectations and is 'as tough as a bent nail'. Best of all, the Aeroprakt gang are extremely professional and talented (many of them came out of the military design environment and it shows) and it has been a pleasure to work with them.<br />Drop by when you can and go for a flight with me.<br /><br />Best,<br />Larry
