        Hi Wil, the house has now been sold, have the deposit, principle coming soon, so am almost ready to buy. What is the state of play with the UK certification?

        Nic, sorry to hear your sad news. My commiserations.
        Would there be any good second hand 912is available?

          Nicholas,

          I hope you are doing well my friend and things have been better for you. I was curious if you have ever heard of the Geiger Engine? This is a Rotary Wankel engine that was purpose built for aircraft use and looks like it will give Rotax a run for their money! I love Rotary engines for numerous reasons and daily drive an RX-8... however they do have a few drawbacks with the Design. I won’t get into all of them here but the only aviation motor I have seen that addresses these design issues is the Geiger Motor. This is a relatively new engine and design, and they only recently went into serial production. That being said this is a huge step for Aviation grade Rotary power as most designs never even made it to production. This is not an autoconversion from a 13B based engine. This motor was designed from the ground up to be an aviation motor. The specs are listed as follows... A single Rotor design will produce roughly 50hp and the dual Rotor version will produce 100hp @7500rpm, so of course there is a Reduction Drive. The Wet weight of this engine is said to be 132lbs , so it should be lighter than the Rotax when installed. What is also interesting about this engine is that is has a pretty impressive torque curve. Most Rotary engines do not produce a lot of torque which is needed for an aircraft! They even have a redundant design for helicopters with two complete 100hp engines driving one PSRU, and the total weight of that unit is said to be 325lbs with 200hp. This is the only Rotary I have seen that has addressed the issue of Rotor Cooling with internal pressurized oil jackets in the rotors. This Rotary engine also uses modern ECU control and is said to have a fuel burn of 4.5-5.3 Gallons an hour. The oil usages is also extremely low as it does not need to inject oil into the combustion chamber to keep the Rotor cool. Now here is the clincher my friends... currently the price listed for the Geiger A2-74 engine is $12,800 US! This is the only engine I have seen recently that could possibly give Rotax a run for their money! You can not beat the price per performance or even the weight of this engine anywhere in the marketplace! The production of these engines was said to have begun in April 2017 with 100 engines. The Company Geiger Motors GmBH is based in Germany and I have recently sent them an enquiry. As I stated this is the first Rotary engine that I have seen for aviation that looks promising!

          Further Engine information... sorry had to use google translate as the website is in German.

          I am extremely impressed with these specs and can’t wait to hear more from the company about these engines. From what I read they are currently testing the engine in a Flight Designs CT and has spent a large amount of time on the test bed. I would Love to hear your thoughts on this engine! I think with the light weight and power of this engine it would be perfect for the AvioMania G1sE! It would obviously have to be tested by you on your G1 and I hope you are able to get ahold of one of these engines for testing to do so! I would love to have a Rotary powered Gyro and feel it would be a perfect setup. I hope this information helps my friend and if you have any questions please feel free to let me know!

          Best Regards,

            Think the 912IS is a around $25,000. It has been out for a while, what are the chances of finding a good second hand one, and around what price?

              Resasi,

              I do really like the 912is engine and I would love to have this engine in a AvioMania G1sE. If I could find one used for under $15k US then I would probably go this route. The Geiger Engine would also be lighter than the 912is engine though, however my concern is about the reliability of these engines! This company is a new company with a new design that is just now starting to build quite a bit of flight time. I am curious to see how one of these engines would preform on the AvioMania G1! I would love to see Nicholas use one of these Rotary engines in one of his aircraft!

              Cheers!

                The reliability of the Rotax engines is a big factor, and I believe that the IS is very fuel efficient, which hopefully translate into longer range.

                  I am expecting the engineering drawings to arrive shortly which then hopefully will permit the design of a testing programme acceptable to the LAA. The test frame is built and in Cyprus but Nicolas wants to make sure it will pass before shipping it. Once structural testing is complete, we can proceed to flight testing. It is difficult to know how long all this will take but we will get there.

                    Thanks Will. Presently in Kilifi and gather Chris and Meg have just arrived.

                    I’'m sorting out hopefully the last of the paperwork on the sale of the house here, which due to a major mistake by the lawyers, has taken over a year to sort out, but it now means that the funds will be available.

                    Also been trying to arrange hanger space for a gyro in a convenient airfield near Gatwick which is not too far away and hopefully not too expensive. As I have learned, it’s like Stan’s 'two week’ syndrome, everything takes a lot longer than anticipated, and now looks as though I will have the money but not a gyro to purchase.

                        Hi Mario

                        Don't think you will need a heater.
                        I'm from San Diego CA and we think anything below 60 is freezing so I have no experience sitting in our convertible enclosed G1sE Genesis Sport in cold weather, even though I'm the US Agent for Aviomania.

                        Here is a quote from an email from a USA G1Se owner regarding his experience so far.
                        I just went flying today. The temperature out side was 45 degrees F.
                        I installed the fan shown below instead of the vent you provide.
                        It works great when it is hot outside to keep me cool but it is great for preventing fog on the canopy.
                        I highly recommend this instead of the vent. I bought it on Amazon for $21 and hooked it to the existing light switch and fuse.
                        The problem with the vent is that you roast in the canopy waiting to take off..

                        In the Winter you fog up as soon as you close the canopy.

                        I always turn on the fan right before I close the canopy. Problem solved for $20.
                        So far it seems it too hot with no mention of needing a heater.
                        ===
                        But I do have experience training in Utah in the winter in the enclosed Calidous when it was 31 degrees for a week of training.
                        The 1st day I had on 3 layers of closes and a long coat.
                        I was still cold while waiting outside.
                        But as soon as we shut the canopy I was cooking with no heater.
                        The next day and from then on I only wore one layer of clothes and waited in the heated hanger and ran to get in the warm non-heated Calidous.
                        If it sunny at 31 degrees it's still very very warm in a Calidos and Cavlon I flew back there and expert our G1Se Sport to be even warmer as it has less cabin space.


                        PS: Here is part of another email from the same new owner of the G1sE Sport who by the way has owned and been flying Dominators for years.
                        There is every reason to think that the gyro you sold me could take over the single place market in America.

                        It is light years ahead of any other single place on the market.

                        If you had a hundred units available, you could sell a hundred units just by showing and demonstrating them at the fly-ins.

                        Just having gyros flying in the Winter like I plan to do is the biggest selling point.

                        The open cockpit only gyros, can only be flown comfortably above 70 degrees.

                        That limits most of our country to just 5 months of flying.

                          I am curious what you were speaking about here?... was this in response to the Geiger engine? If so, that is extremely promising and I would love to hear more about this project!

                          Cheers!

                            Nope - just the extensive testing required by the UK authorities to permit the Aviomania machines to be built and flown here in the UK

                              WNWGJ,

                              I understand now and it makes more sense, I was a bit confused and maybe hopeful! I have heard the UK was one of the toughest places to get certified for Gyros. I hope all goes through smoothly and that you will be flying in no time!

                              Cheers!

                                Hi John, well I popped down to Kenya couple of weeks ago to finalise the sale, as the lawyers had indicated the title deed mishap was about to be sorted. Last Fri the title deeds were issued...and the reverse of the mistake was repeated!!!!!

                                Previously a friend had bought a small section of my plot to build his house and by mistake both areas were deeded to him in one title. Last week the two subdivisions were deeded, but not, one to him and one to me, as it should have been...but both now deeded to me.

                                On the surface sounded as though I could then go ahead and sell my bit, and the lawyers could work on getting his bit deeded back to him. But the lands office and lawyers nixed that as the dates on both titles have to be on the date of the now awaited...again...rectification.

                                "It’s Africa!" the saying goes, and yup it sure is. Bit like the gyro world with the ‘two weeks’ wait. My house and UK certification for the Genesis seem to be proceeding at the same pace who know it may come to pass before I pass away.

                                Sitting in Doha on my way back to UK. Am hoping to perhaps visit my son Stu in LA possibly next week. Might see if I could make it your way this time if I do get over. Does Delta do flights to San Diego?
