Carl,
It would be great to have more tail cone options. Maybe a V-2 and Sprint style for BT-60 through 80. I also really like working with your heavier duty body tubes 115-275 and the BTH-70 and 80. It would be nice to have a BTH-60 with some nose cone and transition options. As you can tell, I really like mid-power. |

I agree, more tail cone options would be sweet.

Ring Tails?
Wouldn't it be nice to have more choices in Ring Tails.
The ones available at Semroc now are the Rt-70 and the Rt-99D RT-70 2.175 2.217" 0.68" .021" 0.090 oz 0.7 oz $0.60 RT-99D 3.668 3.700" .391" .021" 1.42 oz 0.7 oz $0.50 It would be nice to have other choices in sizes. I have cut a few myself form Bt-100 & 101 and realize its a darn good way to seriously cut myself . Also tried to cut an LT-22580 thick wall tube and gave up about a quarter the way around as my hands are my living . Bt-80, Bt-60, Bt-101 Any others anyone?? James Pierson NAR# 77907 |

That would make for an interesting transition section... I'll have to play with the shapes a bit to see what we can contrive...

Conspiracy!
I just tried, several times, to make a Balsa Transition in the shape of a Ping Pong Ball and my R9 keeps crashing !
I believe it to be a conspiracy between TVM and Shrox!! James Pierson NAR# 77907 |

How are you going about it? I use two elliptical sections -- a nose cone and a transition, or two transitions - 1.566" diameter, and 1/2 of this for each half's length. I might even place a thin-walled tube in between the two sections with a length like 0.00001", to act as a reference diameter for launch lugs...

Craig, I am trying to make a solid balsa transition with a forward and aft shoulder. I have been using a front half transition and an Back half transition with demensions of front .759 center 1.5 and back .759 also with shoulders of .7 length and dia. of .71 for an ST-7. I had it created once with an BNC and ST-723 and then added the transitions but, as soon as I deleted the BNC and ST-723 the program shut down again . PS. Using the olgive setting. I still say it's a conspriacy ! James Pierson NAR# 77907 |

Ogee as requested

Ogee as a balsa reducer ST-7 to ST-10 and named BR-710W. It doesn't look too much like a Chess piece or a table leg . Or does it? James Pierson NAR# 77907 Last edited by James Pierson : 04-08-2009 at 07:37 PM. |

Actually, it does have the appearance of a chess pawn... That's OK, since I play chess, too... Badly...
