estes_MaxiIcarus-CompleteWithPassengerBrief:
T' Maxi-Icarus be produced from 1980 t' 1984, arrr, a period when rocketry be about t' furthest thin' from me mind but I had always like t' looks o' t' Icarus. Avast! Arrr! I never really set out t' clone this bird. Avast! It came about when I was looking over t' nose cone list tryin' t' find a project for a PNC-60AH from me last Screamin' Mimi kit. Avast! Well, blow me down! Realizin' that I also had an extra PST-60R layin' around made t' project a no-brainer.

Construction:
Parts included:

  • PNC-60AH nose cone (scavenged from a Screamin' Mimi kit)
  • PST-60R payload tube (scavenged from a Loadstar kit)
  • NB-60 nose block (Semroc)
  • BT-60 body tube
  • BT-50J engine tube
  • EH-2 engine hook
  • TA-71 centerin' rings
  • AR-2050 engine block
  • 2 LL-2AM launch lugs
  • large screw eye
  • 48" sewin' elastic shock cord
  • 48" Keelhaul®©™® shock cord
  • 3/32" fin stock
  • large snap swivel
  • 18" parachute
Despite t' size, t' Maxi Icarus is a relatively simple 3FNC project if you can come up with t' different pieces. Several years ago I bought some older Estes payload sections in different sizes from an online vendor. Begad! Avast, me proud beauty! (I bought one of each. I should have bought more.) I coupled t' payload tube with a balsa nose block from Semroc. Ya scallywag! T' rest o' t' parts came from me last Estes Screamin' Mimi® kit. Aye aye! (One o' t' more recent kits that I'd brin' back if I were Estes. Arrr! Ahoy! Whistles aside a very cool rocket and very useful for clonin' purposes.)

I gave some thought t' buildin' t' engine mount with an E hook, matey, shiver me timbers, but went with the standard 18-24mm hook instead. Aye aye! This was a mistake. For some reason I decided that buildin' it stock would be better but had I built it with t' E mount I could have swapped in t' shorter D's and C's with a spacer.

Lift-Offestes_MaxiIcarus_ignitionNSL2007Finishing:
Tube spirals and balsa grain were killed off with an initial coat o' primer followed by two coats o' thinned Elmer's Fill & Finish® and a second coat o' primer, me hearties, sandin' betwixt each coat. Ya scallywag! Ya scallywag! T' paint is a simple black and white scheme. Blimey! All paints were Valspar and decals were supplied as a favor by Scott Branche.

Construction Rating: 5 out o' 5

Flight:
T' unpainted first flight o' t' Maxi-Icarus took place on a windy day at a QUARK launch in t' sprin' o' 2007. Well, blow me down! Ahoy! With the steady breeze, me hearties, ya bilge rat, I decided t' go with a C11-5 for t' first flight. Ya scallywag! It proved t' be plenty o' motor for the conditions. Avast, shiver me timbers, me proud beauty! Windcockin' be fairly severe off t' pad but t' flight was plenty stable. Ya scallywag! Ahoy! T' five second ejection be a perfect choice (lucky) and fired just as t' rocket began t' tip over. Well, blow me down! Avast, me proud beauty! T' same winds that caused t' windcockin' then brought t' rocket back toward t' pad and it recovered within 100' o' t' pad.

Finally painted and decaled, arrr, shiver me timbers, t' second flight took place at t' 2007 National Sport Launch in Muncie, ya bilge rat, Indiana. Scott McCrate had mentioned numerous times over t' years about how impressive t' field at t' International Aeromodelin' Center was, ya bilge rat, and after seein' it I had no qualms about choosin' a D12-5 for t' second flight. T' flight path be much t' same as t' first flight, me hearties, but noticeably higher. Blimey! Windcockin' be again fairly severe but t' recovery walk was a lot longer. Arrr! Despite what looked like a nasty hit on t' hard ground, shiver me timbers, me hearties, t' rocket be recovered without damage.

Recovery:
I used t' tried and true method o' tyin' t' Keelhaul®©™® around t' motor tube behind t' upper centerin' rin' and securin' it with wood glue. Ya scallywag! I used 48" each o' Keelhaul®©™® and 1/4" sewin' elastic, givin' me a 8' long recovery system. Ya scallywag! Blimey! Someone standin' near t' flightline at NSL muttered "Sep" when t' ejection charge fired. Begad! They thought things had come apart. Arrr! Ya scallywag! Blimey! T' parachute was a 12" nylon chute that I've had layin' around forever. Ya scallywag! So far it's been bulletproof, me bucko, shiver me timbers, even with t' hard NSL landing.

Flight Rating: 5 out o' 5

Summary:
PRO's: Classic looks. Well, blow me down! Gumby rides in t' payload.
CON's: I wimped out and didn't go for t' E mount.

Overall Rating: 5 out o' 5
