Something else I've seen is smearing a very thin layer of Foam Tac on the Depron to improve the bonding of the Blenderm. The glue is allowed to dry before the tape is applied. I've tried this on a small section where the tape had come loose. So far, so good. |

Elevator 0.75" = 20mm Aileron 0.75" = 20mm Rudder 1.25" = 30mm LOW RATE Elevator 0.5" = 13mm Aileron 0.5" = 13mm Rudder 1.0" = 25mm Use low rate initially. (These are throws in each direction.) Make sure the CG is on the step or very slightly ahead. Good luck! |

I learned a valuable lesson today and luckily I still have my polaris in one piece. Here is the short of what I learned.
Flying off water = good Flying off snow = good Flying off snow & water = BAD Here is the long of what I learned. I saw that the lake had opened up on the end that had a dock and there was a really nice level snow covered lake about 60 feet out so since I haven't been able to ROW with my polaris yet, I thought " what a great time to try". WRONG. The initial take off from water seemed good. Not as quick as grass or snow but still good. I landed on the snow covered lake and then jumped into the water and took off again. I continued to play the game of landing and taking off on multiple surfaces when all of a sudden turns became really sluggish and at times it would get stuck in a bank and would not pull out. I assumed the correct reason which was frozen control surfaces. I landed just barely and notice big ice chunks built up around the ailerons. I cleaned it off as best as I could and then just stayed on the snow covered lake after that. It was just about freezing temps and I did not want to take a chance of freezing up the control surfaces again. I guess I will have to just wait another month to run on the water. |

Flying off water when air temperature is below freezing = BAD I discovered this last fall before the lake froze, and fortunately I also landed safely. |

Corrosion resistant control rods
In my ambitious but extraordinarily slow and unconventional polaris build that I am perusing, I am trying to make it durable in a very salty environment. So weeks ago I set forth to buy some stainless steel tig welding rods, but all the local suppliers only stocked bulk quantities. I looked at ebay and there were options, but I had no idea if the metal would be soft or brittle, then the idea dawned on while walking through a discount store. I came across a stainless steel egg whisk. I extracted the wire, places a test piece in salt water and let it evaporate over a week. Not a sign of rust.
$4 for 8 strands, rigid, non-corrosive, non-brittle control rods. Same thickness as my regular wire. Readily available. Nice! Hope that helps others. |

I like the kitchen sourcing idea. Anything fit to use in the kitchen should stand up to salt water. |
