Vent holes on airframe are in middle of fincan & payload [between top & bottom]
Holes for venting av-bay are through airframe about 1.25 inches from edge. 2 of them the 3rd hole is the 1/2 hole for switch wire on break between fincan/payload joint.Like timb2 shows above.
Only 1 shearpin for NC/payload about an inch down from edge of payload.
No on premade sled...you have seen mine in earlier post, make the myself, with left over scraps of G-10 or wood.
I do NOT use ANY motor eject delays on minimum diameter rockets...they are all TOO short. If motor comes with BP [ala CTI remove cap & dump out] For AT don't put any BP [or remove it]in charge well, at this point your delay no longer matters. Trust electronics to figure correct apogee.
When only 1 altimeter in a rocket such as this...I use 2 ejection match per charge for redundancy.
Yes, I'll be using a tracker.I built mine pretty much like CJ's and Tims. And I'll repeat what mark said, fly it with a tracker or dont go with the I500 for your first flight. These skinny rockets disappear quickly. Without a tracker onboard your chances of finding it are very small. I would hesitate even using a H500 for shakedown flight but thats me.
Yeah, I was going to, but after I realized that A. it wouldn't be very strong, and B. Inserting the shock cord mount would limit certain motor choices.I don't use DMS motors so can't say. I used the method CJ proposed in his build thread/instructions.
There is an Aeropack minimum diameter retainer that screws into the ejection well (with an adapter for cti motors I believe). Unsure if it's available in 29mm.
I saw one project recently where a builder used a longer case (ie, 4g for a 3g motor) and made his own adapter that fit inside the spacer at the front of the closure.
Thanks!! I bought one from AMW/ProX.There is an Aeropack minimum diameter retainer that screws into the ejection well (with an adapter for cti motors I believe). Unsure if it's available in 29mm.
