hi everybody after so many years to try floats on one plane, so i have a hobbico superstar 40 and a tower trainer 40,both planes are the same thing with different name; im not sure how much they weight,and i just purchased a great planes set of floats, its a kit, the lenghr is 34.5' inches each float,not sure about weight either, so question: super tigre 45,51 or magnum 52 blue head 4 stroke?
wich engine will perform the best?
regards.

Any of those 2 stroke engines would work fine. It really depends on if the engine runs good and is reliable, not flaky or tempermental.
For a 4 stroke you need to up the displacement some as the 52 four stroke would be too anemic. Years ago I used a Saito 56 on a seaplane and it definitely was under powered. The floats add a lot of drag to the plane, so you need extra power to compensate. I would go with a 4 stroke of around 70 size in displacement if you go that route.

Super Tigre 45, Magnum 46, Magnum 52 two stroke, Magnum 70 4s engines. I have (2) of the Mag 46's and they run great. The 52 two stoke was a little bit more finicky at first but has gobs of power. I love my Magnum 4s engines. Super easy to tune and run smooth as can be.

If you want a cruiser, the Super Tigre 45 or Mag 46. Vertical climbs the Mag 52. All around flyer with good power, the Mag 70fs.


Buzz.

What can you guys tell me about the magnum 70 I'am thinking of putting one in my new piper j3 80" ws this will be my first plane.

The Magnum 4 strokes are great, several friends have the 70's and they are as powerful as the OS 70's (I have two of those). You will not be disappointed. ( BTW You might want to come to our Fun Fly at Farragut Park on July 15-16-17. Some of the Lewiston guys are coming.)

ok thanks Gizmo i'll give that 70 a try,

The Magnum 70 runs nice and is easy to tune.

Thanks BLW
