All looking good Dwain and that is a smart looking radio! Did you buy a 6ch rx as well?

What motor / ESC / prop combination are you using with your 4 cell battery?

What are your plans for covering material?

I was thinking about an alternative venting solution. How about this idea?

Enjoying your posts. Keep it up.

Now then, I have a telemetry module, that will read battery temp, that window could open on a servo switched from the Tx when the heat alarm goes off. thumbs upwinksmiley

I will post up Georges recommendations re motor etc when I get home.

Since my favourite covering is now defunct ( solartex ) I'm not sure what to do. I would like to do the chrome scheme, but I don't know how practical that will be re the coverings available. The scheme in your pic Barryt is typical of the era I suppose, and could be painted over the covering material.

I just have the 12 Ch rx at the moment, there are 8 and 9 Ch rx available, anything less is aimed at ground or multi rotor, in that they are micro sized, and some have gyros in them. A 9 channel Rx is about £20. The 12 Ch is only £28.

I still have a DX7, and it works great. I have all my Heli models in it.

I dropped my JR DSX 9, and broke all the top switches....It still works OK, but the trust is not there....Hence the Radiolink AT 10 v2

There is Oratex as an option. Ok, it's pricier than Solartex was, but it is available. I have no personal experience of it yet, but I shall be trying it at some point. There is also Diacover, although I haven't looked at that in any depth as yet.

I bought a few rolls of Easycoat ( the thinner version of Oracover a.k.a Profilm) from Airtek Hobbies. Again I've yet to use it but it does have a sound reputation. Obviously it isn't really for scale type finishes, such as may be applied to your Cessna. A true aluminium type finish could be problematic, both to obtain and as far as radio signal reception goes. The scheme in Barry's pic doesn't look too bad........

Thanks Percy......a few options to go at there Matey. I wonder if the Oratex takes paint as well as the Solartex did ?

Mind you, having said that I cant get my fave (warbird colors) paint either. DOH!!

The world has gone Mad Boys... sad

Great will be following this build, will be good for my motivation finishing mine.

Must have it some where in my workshop, waiting for some more colour.

Have flown it and yes the Taylor Cessna is a great flyer.

Todays shiny stuff arrived.

The 4 cell 3000 40c lipo flight battery.

The 3 cell Tx battery to replace the 8 dry cells.

A tail wheel assembly.

D.D.

The Flight battery in position. There is bags of room to move it rearwards if needed.

Back to the balsa bashing in a small way, I have chopped the tail wheel mount about quite a bit in an attempt to follow the plan, but in the end I bought a ready made tail wheel assembly, which was cheaper than buying all the gear to make one. Sometimes you have the bits in your stash and sometimes not !!

So more chopping and a new ply wheel mount plus a bit of reinforcing later.............

D.D.

I left the original mount in there and chamfered the new one to meet it....plenty of strength there now......not that I need it with my perfect arrivals......cheeky

Some more balsa will be added to put the profile of the Fuselage back as per the plan.

Go on - leave the window open. You know you want to!

Thanks for the power train specs. Looks like a well balanced system.

I can't imagine how you could obtain a polished aluminium finish. I used painted solartex. I think today I would have to use Koverall or Polyspan. I'm currently experimenting with some interfacing material as used by seamstresses. It seems it could be a good alternative to Polyspan..

Wings next or are you going to try some cabin detail?

Once I have fixed the tail wheel support, I want to get the snakes and servos in, then sheet the fuselage. The fire wall has to go on, and I have to check that for side and down thrust, of 2 and 1 degrees respectively.

Then I may have a go at the wing, or at least the centre section to get the sit on the fuz right.

I was thinking tissue and dope and then chrome paint, I had some once to use on some motorbike mirror backs and stems, it came in a little aerosol can.

A test fit of the tail wheel. Not quite scale but not far off if you close one and squint with the other. I will add the pull pull bits later.

Still on the tail wheel....nerd I have now screwed the tail wheel on to the fuselage having packed out the tail with ply and Balsa to take the screws. I always pre drill any holes and drown them in C.A., this hardens the wood and when the screws go in they make a nice hard thread, almost as good as a captive nut, and don't pull out so easily.

Once the tail wheel support was on I had to rebuild the sides of the Fuselage I had cut off, I then added the solid balsa bottom. I pre cut this to length and profile (wedge shape) to save on planing and sanding. The fuselage sheeting will Butt up to this. I will alter the little ply cover pieces to look more like the side view on the plan, it will look quite close to what was intended.

D.D.

Gluing up with Aliphatic. I use this anywhere sanding is required, C.A. is hard to sand.

I have setup the servo tray, using the two HS 311 standard jobbies. I cut up an old engine bearer fot the servo screws to hold onto. Each servo is wrapped in insulation tape and has double sided tape holding it down as well. In addition each one will have a cover strip made from a door closure cover.

D.D.

Servo position and a wire to see where the snakes will end up.

img_20190413_143515.jpg

The snakes will pass the close to the formers and be let in to stop flexing and slop.

Here you can see the blocks for fixing to.
