Onebadhawk makes some amazing chords. One alone in any kit is cool but it's not enough. So it has too be 2! Plus the PML Spitfire is a cool kit. Bought one and wanting to mod it...
Specs of the kit
Dia: 3.0"
Height: 50.7"
Weight: 41 oz.
MMT: 38mm
Airframe: Quantum Tube
PML Spitfire MOD List
Dual Deployment (2 tube split)
9/16" Tubular Nylon Harness Sewn Loops all round (OneBadHawk)
NOMEX ShockCord Protector Sleeve X3
NOMEX Chute Protector Pad X2
Ditch the piston
Aeropack 38mm retianer
Aeropack 38 - 29mm adapater
Mobius HD Camera
The dual deploy..
2 tube
I've a Pro 38 3G case and spacers. Dead handy as the motor mount is 9'' long, same as the case. This also allows flights from an G46 to an I55 (7.2 burn time). Flight cost is £20 - £50 which I can live with. At a push a 4G (11.5'' long) could fit.
I also bought a 3D printed sled and Mobius HD shroud
eBay too the rescue. I've ordered all stainless steel fittings. £9.36 delivered. Some spares there as well which is handy.

I went for JST connectors on the pyro outlets to the bulkheads. Again eBay https://www.ebay.co.uk/itm/310856187204?_trksid=p2060778.m2749.l2649&ssPageName=STRK:MEBIDX:IT
All the stainless steel hardware for the AV Bay has arrived.
Thinking for the fixed studding end of the AV bay....

So I need to workout the best layout for cutting the body tube.
36" Airframe
-8.5" MMT (.5" is over hanging for Aeropack, true MMT length is 9")
-2.5" NC
=25" Airframe
-5" AV bay
= 20"
20" free airframe to be cut for drogue and main recovery.
36" main folded = 7"
25Ft shock chord wrapped around my hand = 7"
25Ft shock chord wrapped around iPhone 5s = 6"h
Folded in half 4"
25Ft shock chord folded in half and wrapped around my hand = 3"
7" + 3" = 10"
I'm killing a small amount of free time in work. So this what I've worked out
Drogue section is to be 6'' packing volume, 17.5' over all length
Main section is to have 14'' packing volume, 18.5'' over all length.
I think the shock chord method of fold then wrap to make a 3'' bundle works. I might look at finding something too wrap it around to make neater. My kids have a load of them silly eleastic bands (Loom bands) which I can use to hold the chord togther. Making for neat exit then deplyoment.
This means there will be 4'' extra with the main for packing and 3' on the drogue.
The 18.5'' side will have 2'' of the AV bay / coupler fitted via the plastic rivets.
The 17.5'' side will have a 1 caliber as I've been advised/told 3'' of the AV bay / coupler fitted via the normal means of friction.
So here goes...
Oh yeah this is all inside infront of the TV as it's 1c outside and my workshop is bloody cold. I used ones of these to cut the tube, perfect. https://www.screwfix.com/p/angled-compound-mitre-saw/59824
Doesn't look too bad huh. Now to conider how too attach the shock chord to an eyebolt that I will fit on the CR
I have ordered 4 x 4mm A4 Stainless Steel AISI 316 Quick Link https://www.ebay.co.uk/itm/310847659116?_trksid=p2060778.m2749.l2649&ssPageName=STRK:MEBIDX:IT
