I didn't see anything in the plans about aileron controls stops. Any comments on what to do there?

750 Drawing Errors

Posted on February 23, 2013 at 8:30pm 2 Comments

Attention 750 scratch builders. There are some drawing errors that I want to point out to save you the grief of making usless parts. Four of them are in the baggage panels: F-5-4, F-5-5, F-6-2, and F-6-3. The projected views are backwards. There is a good illustration of these parts on FX-1 you can check before you bend. One other is in the fwd fuse F-11-6 which is also backwards. page FA-4 shows which way to bend it.

Hi Jerry, I haven't sold it yet. I have the William Wynn mount, valve covers, manuals and oil separator. I will make someone a nice package deal.

Hi Bruce. I think you will like the Viking very much I got to fly in one at copper state. I also did some instruction in a 750.I went to Carson city Nevada.Bill drake was my instructor.very good instructor. I bought my 701 Wings from a doctor that has a hangar and plane at Peoria airport. I think his name is Dr. Waltrip. Do you know him? Did you sell the Corvair motor? I did not see a price.

Hello Bruce,

CAMit is the manufacturing company that has always made Jabiru engines to Jabiru's spec. They have come out with their own version, similar but better.

I had two Jabiru engines that both failed with camshaft-related issues.  That is why I have switched to CAMit.

CAMit's web site is:

Hi. Bruce. I went with the header tank so I could use all the fuel in the wing tanks and still have a reserve for emergencies. Also I had heard that it was possible to get a fuel starvation situation with low fuel on a steep decent.

Hi Bruce

Deon Here from South Africa. Thanx for the support. Every time i open my plans i just cant wait to start snipping and bending. However, unfortunately, preparations have to be made and finances gathered for materials. But, never the less, any advise, tips and spare parts (ha ha) are welcome.

Kind Regards

Hi Bruce, I see you are a scratch builder. You have no idea how much respect and admiration I have for you guys to tackling such a project. Hope your having fun, good luck.

The Viking engine makes the most sense and gives you the best bang for the buck.  Compare the numbers to a 912...then look at the price.  You get everything you need FWF for less than $17K.  He has a very sharp cowling/polished spinner/3 blade ground adjustable prop/engine mount/wiring harness/dual fuel pumps/FADEC/oil cooler etc.  He has a video on engine installation.  You are able to order the engine /components online as well as put money down and make regular payments.  An Engine ordered March 1st will be ready the end of August.  This will allow you time to run lines/fancy panel etc.

I talked with the presidents of UL, Corvair....they both spoke very highly of Jan Eggenfellar and were very impressed with his technical expertise.  I only wish that he had a salesman to talk to.  He's so busy and trying to manage a rapidly growing business that he sometimes leaves us customers hanging.

Since you have started your fusalaage I thought I would ask how much time you spent drawing the paterns out for the odd shapped side panels?  Did you find it difficult to keep the cut edges identical so the sides matched up?  Most of the build is basiclly straight lines and the side panels are critical to getting the cage to fit properly and square up for proper wing lines.  Are you building the fusalage first so that you can adjust the wing connection points as you build the wings?  It appears that you haven't done the wings yet and that is somehting that I have been considering.  I don't know which is easier to adjust should the need arrise.  Will you build your cage or purchase?  I like the idea of using the pipe to bend some of htose parts.  from you photos it looks like it worked well.  Thank you for your time.
