ok doke !
t long last i `ive got soe pics and some more info on this model
.
now, i know it`s been a few weeks on this, ( maybe even a couple of months ?). however here we go..........
i`ll start with the missile hatch section, the sail that has been seen in previous pictures has now been attached to the missile hatch section, this was done using epoxy with microballoons mixed. a nice and straightforward step. after this the MHS is now complete to the point that it needs painted on the inside before being bonded to the main hull section.
next....
i decided to start assembly of the tech rack ( my apologies if i`m overlapping here
) this was relatively straightforward, the final assembly was very weak and didn`t hold much confidence in it`s completed job! . however,once teh rack is assembled the installation of elctronics can commence, the speed controller ( a specialist sub controller) sits at the rear in the tail section of the tech rack, as does the BTS , (more on this item later) behind these components on another bulkhead is the main drive motor . the drive motor assembly involves a large resin bulkhead which is tapered .this peice is bonded to the tail section of the hull and is the main stress bearing section of the tech rack( and is referred to as bulkhead A). attached to which is the 550 motor, the propshaft go`s througth this section and is sealed by what looks like a small valve stem oil seal , a sprung tensioned lip seal. The prop shaft is held at the exit of the tail section by a self lubricating bush.
The rear planes and rudder peices are installed now , involving holes being drilled straignt, and in bang on the centre lines of the hull, if not then handling problems entail !!
teh dive planes are of a resin construction and needed very little trimming for fitment, the rudder sections required some careful trimming and contiuous dry fitting before final installation. after hich the rather complex looking rudder and dive plane control rods are assembled, i assembled exactly to the plan in the instructions, being .8 mm out when assembled, this took a couple of hours to do , only to find on instalation that the rods where binding, ah well , a small adjustment here and there rectified the fault. stern section nearly assembled ! ( a further 6 hours work !)
next was teh installation of the control rods to the servo`s , which are joined by small collars, looking much like the internals of the acrylic electrical strip connectors you can buy.these rods exited through bulhead A via 2 rubber bellows, i had foresight to fill these with grease before installation, i used a rubber freindly grease and this aided in the instalation, and appears to help in the waterproofing of the hull.
now for some pics
teh sail and missile section attached to the forward hull section, with insulating tape at this moment in time , just checking fit etc.
this is one side of the alloy locking collar, this provides the bayonet fit , which should remain watertight and relatively maintenance free apart from a small touch of grease and when required the replacemend of the rubber seal,( which is situated on the stern section )
this shows the resin cast rubbder and two peice dive planes, also the 6 blade fan type screw.
this shows the tail section control rods, solder still to filed of. but it shows teh relatively tight space for access. there is an access hatch to be secured over this hole.
More to follow ....... ( and it won`t be so long this time
)
