Just a placeholder for now. Who else is joining the build this year?

Just a few photos to show where I am on this journey. I have bought the pre-cut parts etc. from Sarik models by the way. Not finally sure if I will invert the engine yet or stay with 90 deg as per plan.

Photo 1 Shows General view of fuz formers.

Photo 2 Shows some of the ribs. Cut from lite ply.

Photo 3 Shows the engine that will power her. It is an OS62V (same type as in my Skywriter). Looking as if to keep prop driver as per plan then F1 will need to be repositioned about 1/4 to 1/2 in rearwards.  The 62 is a tad longer that a 52 surpass which was what I understand Lindsey Todd used on the prototype

Here is the fuz side layout. sarik have a novel answer to depth of fuz. In 3 parts plus a 3mm doubler. Looks neat but confused initially with shapes.

Quick dry fit to work out Engine and fuel tank layout.

Inverted engine layout seem favourite for me with a SLEC yellow tank which should give a long duration in the air. F2 moves back about 1/2 in and will need a very small infill at base to maintain driver position and cowl shape to plan.

Probably will not have a top hatch which will make front Fuz stronger.

I probably will not have a top hatch over tank as access is fine from inside Fuz.  Again will made front fuz stronger.

The curvy bits on the added on parts of the fuselage increase the glueing area though Pete, so the bond will be stronger. Mmm, not sure about the Slec tank though. I much prefer Dubro or Sullivan tanks. The Sullivan tanks have a moulded in tag on the rear with a hole in so you can hook a bit of wire on and pull them out more easily should the need arise...and the Dubro tanks have the lower part of the tank projecting forward past the filler neck, which virtually eliminates the chance of trapping the tank tubing as it passes through the engine bulkhead. The Slec tanks have a similar design, but use those awful plastic outlets which can get oily, at which point the pipes slip off.........

I'm pleased to see the quality of the lazer cutting looks good. I ordered a set of parts for the Ohmen a couple of weeks back, but they have still to arrive. I did read that Sarik have quite a number of back orders for parts sets though, so it may be a while yet. It's good to see/hear building is gaining popularity once more......

P.S. Adding a floor to the tank bay will make tank extraction easier too. A bit of 1/8 sheet balsa or liteply with holes in it for lightness might do it.

Agree on the idea of a Dubro Tank Percy. I have just used one in my 80 in Seagull Chipmunk. One good thing with a Dubro tank is that you can add a second Clunk pick-up for refuel/defuel which is very useful.

The Sarik parts are pretty nice as well as you have commented. There is a tank floor included in the precut parts as well. My set of parts did take a while from Sarik and when I asked them they seemed to be very busy. Good to hear as we need the plans service to survive and not to be lost.

Cheers

Peter

Hi Pete. As I've said previously I'm a total novice. My kit should be at home when I get back Wednesday so can make a start. I will start on the fuselage so your photos and those of the others will be real help. Please forgive the daft questions that will no doubt be fired off in the coming months

Cheers

Jim

Horizontal bits to help form the tail end of the fuselage? They might also make a tailplane seat?

Build looks good. Parts look nicely cut from what I can see.

I find a bit of string tied around the tank facilitates easy removal back through the former at wing front.

I've bought the laser cut and the wood pack. I know there will be other things to sort but I'm thinking I will be able to get those as I watch every one else build. My intention is electric so will need all of the paraphernalia that will go with that but as I say I hope it will be watch and learn

Thanks

Jim

"but I just don't like those plastic outlets or that threaded nipple into the very same plastic"

New tube, IPA to wipe clean the plastic outlets, dash of silicon sealant to stick the tubes on. They can be wired on as well if more security is desired.

Threaded nipple, light touch required.

Holes in the firewall, make a loose fit with the tubes, then a bit more sealant when the tank is finally installed.

I have heard they can crack around the join, but I've not experienced that problem.

They make good use of the available space, and they've always been reliable for me.

As always, YMMV.

Progress so far.

Basic side fuz underway. I have decided to revert to engine as per plan i.e. 90 deg. F1 is moving about 1cm rearwards. Therefore the tank floor has bee trimmed to suit. The servo floor will be trimmed to allow fuel tank to be fitted/removed to the rear and not via top hatch. which will be made permenant fit and non removable.  I feel that will add strength to the fuz and with a 4 stroke that is no bad thing.

Trial run to see how this works shown below.

Progress is going well on the Fus. No real issues noted so far. Instrument panel has been mounted. I have used some dials that came yonks ago free on a copy of RCM&E. I'm running out so come on mag how about some more please. As you can see I have gone for 90deg engine mount as per plan.

A couple of shots to give an idea of the engine layout. Work in progress. The throttle linkage posed a couple of head scratching moments but all should be well. The Silencer area needs more work however.

Looking good Pete. Thanks to you and Tony for putting out the photos of the instrument panel. There is no way i would have thought to prepare it this early. Just finished painting and gluing mine on the dining room table before swmbo came home from work and caught me.😇
