So here is my attempt at building a telemaster. I have a printed copy of the Denzin/Engel plans from outerzone http://outerzone.co.uk/plan_details.asp?ID=5043

Probably not as pretty as the newer Hobby express version but I am hoping it will do the same job

I started off conventionally with the tail. The stabiliser is a mini wing so it needed some ribs cutting. I managed to cut and sand the outline shape very accurately but the spar slots were not as good because as I ended up cutting them out individualy from each rib with a knife. but I am hoping they are good enough

Phil.

The batteries go in the fuselage. There isn't enough room in the tail for them. wink 2

Nice one Phil

You won't regret building this Phil, the Telemaster is such a relaxing model to fly. The version I built (from a mid 80's kit) had foam wings with strip ailerons, but the fuselage looked exactly the same as the plan you have.

Are you going i.c. or electric?

Phil

If you are going to cut out a number of ribs, one good way is to make a template - I often use 1/16 ply - and use a couple of drawing pins to hold it in position on the balsa while you cut round it. If the template has the spar slots too, then using the template to cut those bits out (I do it after the main body of the rib is cut from the sheet) then you'll get pretty good accuracy......

From his picture he may be going for the electric endurance version. Great building BTW yes

Well yes cymaz, the lipos are perhaps a bit of a clue, but I thought I'd ask anyway.........

It will be electric with the model to be flow by my young son on a buddy box

My 1985 original had a Merco .49 up front, but my next one (plan via David Davis on here) will have an E Flite power .46 motor.......

I did not quite get the stabiliser finished but I made a start on the fin and rudder. This is a sheet construction on the plan but I decided to use a built up version

Probably a good idea Phil as the Telemaster has a long fuselage, and keeping the tail end as light as possible can only be a good thing.

The only alteration I would make to either the six or eight-foot Telemaster would be to add a pair of thin plywood doublers from the nose to a point about 1 or two centimetres beyond the junction of nose sheeting and the longerons. I believe that the original butt joint is a weak point and the addition of the doublers will strengthen the joint.

I am planning a few alterations from the plan but they are really to help me use up the wood stock I already have rather than buy new wood as per the plan. There are also a few vague areas of the plan for example are the servos to be mounted in thin air?

Starting to build up the formers and fuselage pieces. At the moment I and just cutting out parts really without any proper assembly yet ant there is still a few wing ribs to cut out

I may be getting ahead of myself but I have been thinking about covering. I thought I may give the hobby king covering a try. would one 5m roll be enough do you think?

5m enough Phil? I think I'd choose a colour I liked and buy two rolls. That way, the stuff you had left over would go for the next model(s) you built.......

I always tended to go for a nice vibrant red or yellow as a base, then add another colour at covering time to complement or contrast with it, depending how I felt at the time.

Re servo mounting: I think I'd simply bridge the gap with 2 vertical 3/16 balsa rails the correct distance apart, then fix my servo rails across the fuselage from there.

All of the Telemasters I built or sold had a slightly differently shaped fuselage to the one which is shown on your Outerzone plan. Your plan is a copy of Karl-Heinz Denzin's protoype

The main difference is that the kit models had a stringer from the centre of the nose sheeting to the rear of the fuselage and another one at the top and bottom of the fuselage. This picture of my uncovered Senior Telemaster, the eight-foot version will give you some idea.

Yes David, my mid 80's kit had the stringer/longeron which you mention. It was this I glued my servo rails to, as it was in exactly the place I chose to mount them. It worked out just fine as I recall.

The extra stringer would in fact near enough follow the line of the pushrod shown on Phil's Outerzone plan.
