RC Cosmos Mariner
I did some more work on my RC CM yesterday. Originally had decided to make it BG with the internals from the kit, but due to poor parts fit (the front CR and weights barely fit into the BT-55 tube) I'm moving on to an RG.
Progress so far (photos coming later): Built all the balsa parts. Cut out the sub fin to allow full movement of both evelvons. Made new motor mount (sized to accept E9-P motors). Cut new BT-55 tube to hold motor mount. Covered exposed balsa with trim monokote. Sourced the RC gear and mocked up servo placement (in hanily provided molded trays in the bottom half of the body shell). Things to work on: Control linkages. Hinges. Assembly and paint. kj |

Interesting idea. Someone flew one of these at NARAM and it had a great looking free flight recovery. Of course, we've all heard of the poor flight reports as well. I look forward to seeing this one.

That would be me, I flew it at NARAM 48 in SFFS. It did glide rather nicely. I flew it twice, I DQ the first flight because the parachute got caught on the pod hood and the pod streamed line in. There was a little stall in the first glide. Made a adjustment to the chute lines and add a little nose weight the next flight was qualified and the glide was very nice. Much better then you would think something that heavy could glide. What R/C gear are you using? You can see pictures of my CM on the NARAM Live site. Chris got a couple of nice shots of it.

It was at NARAM 50 that Foose and I saw the good flight of which he speaks... As I recall (probably incorrectly) the model was unpainted. I looked up because the ejection charge sounded like a shotgun blast |

O, I stand ( actually sit ) corrected. In either case, they can be made to glide nice. A R/C version would be cool. |

Nothing fancy. I usually keep a bunch of cheap small servos around. I got a few of these: http://www.rc-dymond.com/index3.php?productID=1436 when they were on sale. Will probably use one of my Berg recievers and a small 200mah battery. kj |

Anybody want to share some tips on how to make this kit glide better? Whenever I see on in the bag, it looks more like a model boat than a rocket. Bill |

You are not going to win any duration events with this, but it can be made to glide well for its size and weight. Also, this shouldn't be your first glider. Try a Quest Flat Cat or something like that first. If you follow the steps 13 & 14 in the instructions, that really all you need. One other thing is run a string through the launch lug and make sure the model balances side to side. Find some tall grass to do your test glides over. Try to do your test glides when there is little or no wind. Make sure your throw is even and don't try to over throw it. This is what I did. After the first flight, it did notice it had a slight stall in flight, so I added a little more nose weight. The second flight was fine. Trimming gliders is a art and you will get better with practice. |

The instructions call for a silicone glue for attaching the vacuformed plastic hulls to the wing. Any particular brand work better than others?
Would something like Weldbond work? The label mentions many non-porous materials, but not plastic; perhaps because there are so many different kinds. Bill |
