Nick,
There is nothing in the A6 rules that would prohibit the use of tubing sleeves (or O rings). I don't think there is anything in the Ministick rules that would prohibit them either since the tubes are not used to restrict torque. LLP rules state " no gadgets of any kind are allowed on the airplane". I don't think a tube meets the definition of a gadget, but if it does then so would an "O" ring. Someone might argue that it is not on the airplane it is on the motor.

Subject: Re: [Indoor_Construction] model weight calculation

Wire spacers, when used on a F1D are considered to be part of the model weight. As for O-rings, they are normally counted towards the rubber weight. However, they can be cut off the motor as needed after the flight to meet a maximum motor weight.

I would personally define anything that stays affixed to the model as part of the model weight and anything that is not left on the model when the rubber is removed as part of the rubber weight. I would think the tubbing sleeves would fall into the same category as o-rings because they help handle the rubber. However, I could see an argument for calling them a structural element since they are a mechanism for preventing the rubber from bunching at the hooks.

It will be interesting to hear what the list has to say because if tubing sleeves are ruled a rubber control mechanism then they would be illegal for Ministick, A-6 and LPP.
