Here's all the parts!
There are three bags of the molded plastic pieces.
From the side of the box they recommend using the Estes Porta Pad II and controller. For a model this big and heavy I'd prefer a heavier duty launcher.
They also say: "and launch controller". The instructions do say to use the 2230 and 2240 controller.
Only one engine is recommended, the E30-4.
More parts unique to this kit are in the next post.
Hey Chris,
ReplyDeleteThis must be your lucky day. I just checked the Estes website and they have a PSII bundle on special for about $45, which includes the E launch controller (#2230) and E launch pad (#2238), plus 3 PSII rockets (including the gigantic Mammoth). Plus free shipping on all orders over $39.99! Perfect for the LJII. Come on, Chris, I know you want to get it.
Hi BAR,
DeleteSorry - I'm not really interested in ARTF models. It looks like Estes has a lot of RTF rockets they have to get rid of. I can bet a lot of schools are picking up on these.
Have your done your research on glues for this model? With styrene and ABS parts glued to each other, the choice of glue is critical. I was one of the early adopters of this model and learned the hard way. If not, look for George Gassaway's thread. Last I read, Tenax 7R and the Plastruct glue for gluing ABS to styrene were the glues that would actually bond these materials. I'm actually planning on a second build to correct this, and the fact that my wrap somehow ended up with gaps between the wrap and airframe, even though it was tight when applied.
ReplyDeleteHi Metal,
DeleteI've read the TRf build thread. I've had experience with many different glues and materials so I should be good to go! (Fingers crossed!) It makes you wonder how many builders used the wrong tube plastic cement only to have fins break off on landing.
As a teen I always wanted the Centuri LJ-II kit also. As you said that was a small fortune when my rocket funds came from the occasional soda bottle found along the road.
ReplyDeleteI am really looking forward to following this build as I have several hidden away.
Somehow I've resisted buying this kit - I think it's my interest in the original Little Joe that's held me back. Having Chris build one - the blog is such a great reference - may change my mind. That plus the Hobby Lobby discounted Mercury Redstone I bought intending to transform into a LJI.
ReplyDeleteChris, any potential for building this as a cluster motor version or with an interchangeable motor mount?
Hi Openroad,
DeleteNo, I'll be building the engine mount stock. There are a few single 24mm engines that will work well.
The posted TRF builds have already answered many concerns I had about glues and reinforcements.
Built this as a cluster, 1 D12 in the center, 6 c6 in place of the stock nozzles. Flew it this past weekend at the TTRA launch near Plant City. Flew perfect! Did nor use an altimeter, but it seemed to just about double the altitude when flown with the suggested E30.
ReplyDeleteUsed Pinewood Derby weights, epoxied to plywood disks in the CM section. Anchored in place with a nut & bolt, the disks can be removed or flown in any order so as to fly on a single motor, center and 3 outboard, or all 7.
Only problem is that the LES tower did not survive landing. Have multiple pieces to reassemble. Will fly without the tower next time.
