Any new work and pictures is added to the bottom along with a Date they where Posted

Oct 24, Deep Cleaning all Pieces

  • did I mention CF strip on the upper spar
  • CF tow lower spar
  • triangle gusset from nose block back to former at wing rod tube, fuse bottom I like to round the corners here
  • CF pushrods.
  • will look at getting the elevator pushrod to exit within the walls of the fuselage
  • removable, bolt on stab is in Order
  • jump in with your Build Ideas

Sept 25

More Pictures soon, still time to grab a Kit and join in , chime in with you Build Details, Pictures, queries and ideas.

  •  Instructions mention extra ply root ribs for side of fuselage, will cut them from 1/8 lite-ply as couldn’t find them, 1/4 to 3/8 Inch fillet
  • some formers for fuselage are numbered, will sort thru to ID their location, tabs will need a bit of thinning to fit slots
  • will add hole to nose block for lead
  • found spare set of 1/64 ply doublers for stab
  • ribs are all numbered, still looking for some reference to these numbers elsewhere on the plans or documentation

UPdate, Aug 28 2018

there’s appears to be interest in a parallel Build with a fellow Builder in Ohio

woo hoo,

UPdate, May 31 2018

This project is still a go just need to clear some other stuff from the Deck. Apparently these Kits are hard to get now, that surely will create demand

May 21 2017

Well here we are 2017 May already, have had a chance to look thru this kit and so far I like what I see, everything nicely packed. I might add though that the spars don’t fit into the rib notches, there’s at least 1/32 ” in the difference. In this day in age with Laser cutters I would have thought that getting these notches to fit the spars would be a pita.

I will file the notches wider, and I reckon they will have to be deeper as well, to suit the spar material supplied.

The one other item I have learned to watch for is warped fuselage sides. They are laser cut from a sheet and I have seen the straight edges top and bottom get a twist as much as 3/ 16. If that is one way on 1 side and the other opposite it makes for quite a challenge getting a straight fuse.

Stay tuned :)

Dec 17 Unpacking a Oly III Kit, nicely done

Yes, tape on wings

(built up wing saddle on fuse)   requires longer wing rod.

+ servos in the spoiler bays

You could simply run the spoiler servo lead inside the fuse –

I would simply plug the spoiler servo leads to leads from the Rx.

Build Moving Forward, Dec 04

Took a minute to weigh some pieces and get some thoughts on what direction to head

Stab


elevator


tip pane ribs


1/8 x 3/8 spars I have marked the weights


wing panel LE Balsa


trailing edge , can’t remember?


wing tips


fuselage sides, rear top filler, etc


fuselage lite ply


spar ply doubblers and panel joint doubblers


Canopy and canopy aft Balsa


Some more weights

rudder , fin , stab doublers, I found spare doublers as well


Nose Block, will hollow out Later


Balsa shearwebs


Misc Hardware


Lite ply sheets


Lite ply fuse sides


fuse formers, removed from sheets need more holes , up down?


rear fuse ply doubler


forward fuse sides, and doubler, aft sides are balsa


glue with bottom edges aligned against level, and checked for straightness


forward ply aft Balsa, watch for warps in lower edge of rear balsa, it needs to be straight


Ready for ply doubbler


Some More Fuse Build, a Look at the ribs


 

I just stacked both sides with doublers and glue in place and weighed them down, Once the ply doublers are in place I’ll see how all the formers fit


ribs , 5-15 is ribs 2 thru 15 panels


No notches for spoilers, and the root balsa rib has a hole for wing rod tube


tip panel ribs


more ribs


ribs 5 thru 15 and 2 thru 4


spars a strong 3/8 inch , perhaps 1/32 over


spars a strong 1/8 thick, they need to fit the notches


got them stacked and now will file the spar notches


same for the tip panel ribs


Ok, these look better


Fuselage sides and formers, whats Up, where do they go, get it right


DEc 14 , Getting things right

nose block and fuse pushed together


formers appear to fit this way, dry fitting clears up a lot of things. Not going to use the tray as servos have different size


more glue


doublers at Rear?


nose block lead room, a bit of a guess, I may not need it later though


rudder, top and bottom get some sheet


wing panel trailing edges, used top and bottom 1/16 sheet


wing panel ribs spar leading edge


tip panel start, rear of lower TE sheet is cut straight to start


Number 27 is not the last rib, I had to look for number 28 :)


fine measuring , no more questions


Pins,  is that spar glued to the sheet , and yes, it is   not parallel to the rear edge. Kind of a gottcha moment here.

so

So are the spars in one plane or the rear edge of the d-box sheet, will have to check that out before I join the inner and outer Panels.  Long wings, you going to build joiner boxes and a Joiner


DEC 18    More Wing Panel Build, Inner Panel, with CF strips and Tow

CF strip at top and tow at bottom on inboard panel spars


lower sheet and spar, spar glued in place and then I pin it down

lower rear trailing edge , I like to bevel it before I place it on the board


here is the spacer I use between for and aft lower sheet


forward sheeting with lower spar in place


spar located and glued in place


straight edges all around, I like to draw the lower dbox sheet with spar affixed back to a straight edge before I get started with the rib placement


placing the lower sheeting, I like to use a spacer and repeat with the other side panel


one rib at a time, have a piece of aileron stock under the LE of the lower d box sheet, and that way I can glue the full lower rib edges.


making sure the lower rib edges are down flat to the board


Dec 28

ribs


Wings

I like to bevel the TE sheet before adding the ribs


the inboard lower filler sheet, a clean round and the other side is here somewhere


some pins get the two edges down tite


added some marks for the ribs here, to get them located later


left inner panel lower filler sheeting


left panel and lower inboard sheeting


more left lower sheet


upper spar in place


forward ply spar doubler


More Fuselage

Fuse formers, I have the orientation in order, and as part of the diet plan, making holes bigger


Holes cut and cleaned up


HV 6100 servos, and big holed servo tray, I am going in a different direction


still dry fitting, and the pushrods should go thru here


there’s a spare hole perhaps for a antenna guide for 72 MHZ


Root ribs from 1/8 lite ply will be added to the fuse 3 pieces each side. Longer tube and wing rod in order though


OK, this should work, but will fillet nicely once this gets glued together


the tabs and corresponding slots needed some slight clean up to slide together


canopy opening doubler fit to fuselage formers


OK, this should work


I want to round the forward bottom corners, so I have added a lower 1/4 x 1/4 fillet


All good


Fuselage Cover, really

Lower fuselage ply set , aligned with premarked centerlines, and marks on formers.


I don’t use clamps here just some weights


ply doubler for tow hook


I had previously notched the bottom corners of the formers to allow the lower corner tri to pass thru


I needed some filler here to get the top of the nose block wider to suit the width of the fuse once the balsa gets added to the side


fuse hatch frame and 1/32 ply cover


This cover turned out clean, and will need some accoutrements added later to keep it attached to the fuselage


Going to clean up the tail and get the horn for the elevator in the center of the fuselage


rear doubler for the inboard end of an inner wing panel

soon, panel join and top sheeting


More Photos

rear doubler in place, there are two actually


left panel second doubler, I added a doubler at a tine


pull wires so I can weave some thread thru later to wrap the spar buildup


wrap sheeted undersides should go better with this setup


OK, here I have some thread thru


a couple loops to get thread moving in both directions


this should do it


3 bays each with a wrap


These lines will get tied off and I will spread a bit of epoxy over the lay


I have shaped the leading edge to tie into the upperside of the lower sheeting


the upper edge of the leading edge is also shaped to a large extent before it gets glued in place


I’ll set this aside for the glue to set up


working on the tip to inner panel join


tip panel block up, and aligned over a straight line on the board


spoiler servo opening framing, will pick up the ply covers later


spoiler oping frame


spoiler opening frame


spoiler opening frames in place


spoiler and spoiler sub spar


join at tip panel


tip panel joiner doublers


prefit and ready for epoxy


I will drill a couple holes and run a CF tube between the spar fillers


this should be close


tip shape


wing tip block


On this Day

leading edge top sheet, with a sliver removed from the rear edge to get it straight


about 1/16 or so wide at the middle


here I have added a strip to the forward edge of the top sheet, to make up for the shortfall as a result of setting the sheet over the top of the LE rather then butting it up against the back


trailing edge top sheet, epoxy used at the bevel, and titebond over the ribs.


a level place over the top after will get the sheet down straight


level and weights in place over the trailing edge


pins at the forward edge where the TE meets the ribs


a closer look at the end


a fillet is added top and bottom, where the tip panel TE sheet meets the inboard panel

Feb 13

Some time later, not a big fan of balsa aft fuselage sides, especially when they are accurately laser cut. Trees move, and this balsa is no different

wing root transition 3 pieces 1/8 lite ply at each wing to fuse connection


some CF tube as a spar system for the stab


this 1/64 ply was included in the kit to use as doublers at the stab center


tubing and t nuts, needed for bolt down stab, and center re inforcing


wooden interface locks


need more blocks to secure the fin


2-56 screws up thru to get the lock in the fin


tip block holes


they are supposed to mesh with the wing openings


a bit of weight reduction as well

Mar 03

rear of canopy


magnet latch hold down


xxx


Hatch, and forward end will get filled to add meat for a better transition from the canopy


new hatch forward frame member


canopy aft, and bleeding it round into the fuse at the wing roots


Nose shape, still needs some work


here is the sum of what I have done to bolt on the tail group

Mar 17

wow, 2 weeks since I was last here, I have since added the top sheeting , added some fillets into the corners of the boom and got some more detail work done with the canopy and the hatch.

canopy forward edge where it meets the nose block


Canopy rear, as well as forward end of hatch


rear edge of hatch


wing root filler and fillet, needs to be cleaned up and sanded


underside of canopy, left right stops, and forward pin locater


Rear canopy fuse magnets as well as pin for forward edge of hatch

by rotating the pin up, pulling forward, you can release the forward edge of the hatch to remove it


pushing down at the rear of the hatch flips the canopy out


forward edge of hatch


underside of both canopy and hatch


Rear hatch hold down

:)

May Day 2019 May 01

Final days of the Build, Paint, covering, controls, some stab work and of course sanding. I also put some effort into CG at this point, so putting the plane together is also part of the package

set up with 5 cell eneloop, this gives me an idea where to safe some weight, It’s the tail as usual
servos set at wings
looks like I still need to clean up where the wings meet the fuse
left tip panel, these one piece wings are quite long and care needs to be taken with handling especially at the trailing edge where there is no vertical filler sheet between the top and bottom sheet
inner panel, I rounded out the root filler sheet top and bottom I prefer this over square transitions
fin and rudder knock outs, this took 20% of the weight out
stab also needs some knock outs, as well as a bit of a spar after
a bit of a cardboard template will get the same knock outs on the other side
this should work
what color huum, who knows, white , yellow , violet, stripes :)
I transition the holes aft into the moveable part of the stab
yes, nothing exciting here, just a white vertical
The fuse after a few coats brushed on and sanded
fillets,
rudder clean up, off to covering
fin also gets the white treatment
here we go
violet on the inboard
then blue, and a Yellow tip
still need to run the iron with the sock over, then I go over with the trim iron on the ribs, and more closely on the edges, then another pass with the sock on the big iron

May 05 2019

misc hardware I still need to get in place
servo tray 2 x 6100 servos here
access hatch between wing roots
stab mount, holes for screws to secure stabs, and clearance holes for 2-56 screws that secure fin to H stab
the 6100’s
underside of h stab with 2 screws 2-56 ready to go
screws secure, t- nuts in the other two holes accept the screws that come up thru the boom from the underside
pushrod exit
4 40 screws used to hold stab in place
white for H stab
violet voila
white
wing set

May 10 , Oly is Finished, will fly soon, stand By
