| Very IMPRESSIVE John Cooper - a 24" laser cut Guillow Beaver with sheeted balsa floats that flies Free Flight, and skims to a soft landing on the gym floor on the balsa floats! REMARKABLE !! I like your 30 second video https://www.youtube.com/watch?v=rdXRtjpVRyM&feature=youtu.behttps://www.youtube.com/watch?v=rdXRtjpVRyM&feature=youtu.be |

| Extra Power - Here is a second video, with longer and thicker rubber and 700 turns:

I also got the model to actually ROG with this amount of power (sorry no video yet), but it only got about 8 ft high. |

| I remember hearing that "with a big enough engine you could make a piano fly." |

| Nicely trimmed! A bit more thrust and I think you've got it. Very well done! |

| That's cool!! |

| I got a chance to start trimming the model - Video: http://www.youtube.com/watch?v=rdXRtjpVRyM&feature=youtu.be . I needed to reduce the prop diameter and add a larger sub fin to get it to stop it from spiralling in a tight turn. This flight has 500 turns. I think my balsa prop is suspect and that I could get a longer flight with a better prop. The model will not even come close to doing an R.O.G. - there is too much friction with the floor. I will add little wheels to the floats. |

| Possibly " movement on tributaries or reservoirs"... MOTOR! |

| WOW!!! |

| In order to ROW you'll need some extra power at the start which is provided by the Onboard Aquatic Reserve, OAR. |

| Glad to see another Beaver float plane join the V.A. Fun kit to build. Very much like your version. I used a 5" RC Champ prop for a scale look, but your 3 blade looks better. |

| WoW. Thanks you learn a fact very day.. Love the floats. Maybe rise off water is appropriate.😃 |
| hjlittman, Comment for image # 30524 | 23 Jan 14 16:14 |
| The struts, as originally designed were scale length. This would not give clearance for the 7 inch, black prop in the kit and the 5 inch, red prop is just for show, not flying. Your 3-blader looks good, I have used a very aggressive, 6 inch, Ikara (Czech) prop with a prototype on floats, but it is at kit weight of 50 grams, with floats, and while it flies would have no chance at an R.O.G. The real challenge would be to get one of these to R.O.W.! |

| Ah, another aeronautical term to master! |
| John Cooper, Comment for image # 30524 | 23 Jan 14 16:03 |
| John - ROG is Rise Off Ground, mostly a free flight modelling term for the somewhat ellusive ability of a model to take off on its own power. |

| It's JFB!! |

| John, Wonderful rendition. May I inquire as to what a "ROG" is? |
| John Cooper, Image # 30524 | 23 Jan 14 13:32 |
Finished, balanced and weighing in at 33.8g (1.39oz), without rubber. This is a good weight for indoor flying and may even be able to R.O.G. off a smooth floor. Unfortunately I built the float struts too short and needed to use a smaller home-build 3 blade balsa prop instead of the kit prop. |

| This is looking fantastic!! |
