Av/ebay attachment

Still all new to this and finding my feet.

For example were referring to 4" tubing.

How does one fit an av bay / eBay with body tube either side?

IE:

Option 1 - booster, av bay, short BT, NC

Option 2 - booster, short BT, av bay, short BT, NC

So how do you do it?? I can't seam to find anything online saying or showing how

The most typical setup is:

Nose cone
Upper body tube (short length for main parachute)
Coupler (contains A/V bay & sled)
Lower airframe

All the best, James

There are many methods - I prefer PEM nuts and screws, others use plastic rivets.

Here's a thread which may help: Designing an AV bay for DD

I use plastic rivets.

See here ....it's 3inch but everything is the same. Just scan the build briefly, then find what you want in the index. This is a sticky at the top of the page under high power.

I have used plastic rivets & stainless set screws among others......Plastic rivets are simplest way to go for convenience & sport flying.

I prefer to use rivets for cardboard but for composite I prefer screws countersunk to the airframe.

Thank you everyone. I spent a good 2 hours having a read and feel ready to rebuild.

Have orders some 6mm (1/4) plastic rivets (all the UK) has too offer. Have used these on my model aircraft so see the idea etc etc.
