    Have you built the aircraft? what would you want for the molds? Not a huge fan of the motor on a high pedestal though. What is your location? How did you acquire the molds?

    It becomes an issue with tractor props taking off and landing on water as the spray hits the prop. Float planes sit much higher on the water than a true amphibious and reduce this issue. Cooling is defiantly a concern, I will be placing my radiator, oil cooler, inter-cooler slightly in front...

    Definatly do not use silicone, sorry I had silicone on the brain. I used jb weld brand long cure time high heat epoxy. That Is what I Used in my sandrail build and have had no problems. All original 13b parts, reasoning the rotor housings are already alluminum, although weight is crucial in...

    I love the shearwater, beautiful plane. They were trying to certify it and ran out of funds and energy. Right now nothing on it is available. I chatted with the creator I guess hes flown it and passed certain steps but couldnt get funding for the next step. It has a v tail which overcomes...

    The seawind is the speed range I am looking for. It has the engine on the rear which requires much more structure and weight. It weighs 2300 empty and requires 400 hp to acheive the performance thats why it burns 16 gph. I almost bought a seawind kit but after chatting with seawind and a few...

    4 place 175 lbs plus 200lbs baggage plus fuel Traditional floats are very ineffeciant, so I am not looking to go that way. One mazda 13b original rebuilt with upgraded seals and such, slightly ported but not want to increase the rpm range much, turbo yes put out around 315 hp @ 6500 rpm 130...

    I have a friend in Idaho that has 13b in his four seat land plane. He is at around 8 gal per hour, that is where I got my fuel consumption data. His plane is around 1400 lbs ready to fly. Mine should be close to that according to my figures. The seabee is a very useful plane, not the most...

    true 4 seater amphibious pusher plans

    I appreciate the positive helpful comments. I totally understand the undertaking and do not need the lecture. I love the sea bear, but since Id need more power Id have to go with 2-13b's, of which I have, but then at 8 gallons per hour per engine I am now at 16 gallons per hour fuel burn...

    Its to slow as is. If I increase engines it costs way to much to maintain and fly as a twin. I know the behind cabin will be cut vertical to allow for propeller. We will have a front door and a rear hatch. Tail draggers are not my thing and way more expensive to insure. I know the changes...

    What are everyones thoughts on the Seabear? I found an engineer and he thinks that is a good starting point. Change to one pusher overhead and a tricycle retractable landing gear. Hes working on the balance and such. Just seeing what you all think. http://www.seabearaircraft.com/aircraft/

    I am 3 years into a 4 passenger amphibious airplane. Around 300 hp from a 13b turbo running around 6000 rpm's with a constant speed propeller speed around 2500 with my 2:40 prsu unit. I have the motor completed and dynoed, Haven't permanently constructed intake and exhaust as need in place to...

    No offense taken, I appreciate all input and am not thin skined. Several threads are available on the Mazda engine in aviation. The authority on the subject retired, and his rotary engine company has dropped the aircraft divison. His name is Tracy Crook, hes written a book on his conversions...

    The seawind looks sleek but is way large and heavy in unessacary areas. If theyd selll me plans I'd start there but they wont.

    The 13b is capable of 600-700 hp with a turbo, but it requires severe porting and high rpms. I have on an a sand rail. We do not want to run high rpms and in an aircraft want conservative reliable performance. the 20b puts out 300hp naturally aspirated but finding one reasonable priced is...

    Thank you for the input. We are looking for something much smaller and sleeker than those mentioned. Like an expanded searey with more hp, faster flight speed, yet stiil good economy. I know its a tough one. BB will sell me their plans but its only been on solidworks not built and no...
