My wife and i have agreed on a 7 day challenge which kicks off today, mine is to cut, build, cover AND fly a Nigel Hawes 30" Tucano, hers is to read 7 books from her large collection of unread ones, books to read are of my choice from those on the shelves. I have given her a good selection of fiction and non fiction including War & Peace devil, that should slow her down a bit!

I am not the most experienced or the fastest builder by a long way but I was looking at the Tucano plan as a chaser for the Nijhuis Gnat that will be my entry into the 2020 Mass build. The Tucano looks to be an easy straight forward build and on checking my wood stock i found i had everything required, i also have a Mega 400/15/7 motor and a suitable controller and 3s battery packs. It should go like stink on that motor, i flew a friends Tucano back in 2001 when the free plan came out, it was on a brushed 400 and 8 Can cells and that went pretty well till he sprayed it all over the strip having done an inverted low pass and pulled up instead of down at the far end!

The colour scheme will be non scale but bright as it will get small quickly, i have plenty of Profilm that i dont use these days so i will make something up from what i have. The only thing i need to buy is a canopy, Sarik does them and Vortex used to but i have had no reply to the message i sent so i guess they have now gone.........

Will post an update at the end of each evening with that days progress........wish me luck!

Good luck Martin, sounds like a fun challenge, especially as you won't have any interruptions! On the other hand you may have to take it in turns to make a brew, I'm sure I won't be the only one watching every evening, I just hope the seventh day is not to bad as you have to fly it come what may lol!

Yes T is going to be done on a whoever is nearest the kitchen basis, if i make the deadline i am fully prepared to be up at the crack of dawn to get a flight in before the wind gets up if necessary, i have a day off work on Monday so i will be aiming for then. I should add that it won`t be built with Cyano which would have speeded up the build as i get breathing problems if i use it, Good old Aliphatic will be my weapon of choice with a small amount done with epoxy. The airframe and motor set up should handle a fair amount of wind but it is always better not to have to maiden a plane in a force 9 gale disgust

Better but not impossible, you've set a challenge (come hell or high water), I'm looking forward to the maiden (from the comfort of my office wink).

Excellent, watching with interest, should be easily possible in a 'working week' of days.

I don't think Vortex Vacforms is the day job for the proprietor - give them an appropriate time to respond - you might not get the canopy within your 7 day deadline. It might be quicker to carve/sand/film cover something from block.

For the purpose of the contest you should define read - does that just mean the title or first page or entire book!

A fake canopy could be made in very few little time by sanding a block of white foam to shape with new coarse glasspaper and then covering with brown paper & PVA or just film. But maybe Vortex will come up with the canopy and cockpit interior in time or perhaps your friend has the remains of his crashed one saved up from years back......

Ita great little plane . I was given the very first production kit that Nigel Hawes made by a friend who bought it years ago and gave it to me shortly after . It sat in my loft for some time before I built it it was originally powered by a Cox TeeDee 051 but changed it to electric as I constantly had problems with engine runs The old brushed motors had been replaced by brushless by the time I had removed the cox and fitted a 2750Kv outrunner , cost £5 on ebay .Its so fast and powerful on a 1500 3s lipo . It goes vertical from your hand , count to three slowly and its at the limits of sight vertically . Its a go to model when ever I want a quick flight although its easy to fly with an excellent fast glide .

I'd go so far to say thats its probably the simplest and best fun model I have built in many years .

Choose a bright colour scheme as edge on it can disappear as wings are very thin.

Good luck with the build and have fun

Thanks for the encouragement guys, well tonight i have all the parts cut out and the wing sections have been glued and pinned down, i had hoped to have the fuselage glued and in my SLEC jig but it is now 23.15 and i have to be up for work at 5am..........i know light weight!!

Tomorrow won`t see a huge amount done as i have the editorial to write for my car club magazine but i hope to have the wing tips on, fuselage formers in and the fuselage glued together and in the jig, plus the ply motor mount and dihedral braces cut out.

Memsahb has finished the first book and is 2/3rds of the way through the second! Still she has that War & Peace hanging over her, apparently that will be the last one read.

Update late tomorrow evening..............

Off to a great start there martin.

Surely you mean "up at 5am for more building" ???

Day two update, Wings and tail plane have their tips glued on and fuselage is now glued and in the SLEC jig. A couple of cock ups along the way, the minor of the two was to glue the motor mount on with Aliphatic, as soon as it was fitted i started thinking that i should have used epoxy for that. The glue was still wet so i took it off, cleaned it up and used 15 min epoxy for that and the triangular section stiffeners that beef it up. The larger mistake was a mis reading of the plan due to my plan building inexperience, i have attached a picture of the tail section of the plan to show what i have done. The Main part of the fin is made up of three sections, the front and rear are made from soft 1/8 balsa, the Centre part is the fin post made from stiff 1/8, i misread the plan and thought that this post was glued to the rear of the fuz. It is in fact supposed to go inside the rear of the fuselage sides, i cut the sides to the dotted line of the front of the post instead of the rear of it which was the solid line ..........Doh

Not having the time or wood to recut both fuz sides i decided to glue the sides together as cut and i will epoxy the fin post to the rear of my sides. Once dry i will use scrap sheet to fill in the difference between the post and the sides.

End of day three and work today concentrated on the fuselage, the fin post was fitted using 15 min epoxy and was left to dry with a right angle leant against both sides to ensure it was square with the fuselage. the fuz sides were pulled in at the top to give the curved shape and given a dab of 5 min epoxy, The top decking, front and rear was fitted, this will be sanded to shape tomorrow and a motor access hatch will be cut. The front bottom 1/8 sheet went on and the servo rails were made from 1/4" square balsa capped with 1/16" ply for the servo screws.

Reasonably happy with where it is at , the Mrs is now onto book 4 of the 7.................

Another update tomorrow evening.

Excellent challenge Martin, I love it.

I'd link to the many threads on this particular model from when it was a mass build subject its self, but that would be distracting and take up your time.

I'd also link to my thread on building a N Hawes Whizzza in hotel bedrooms while working away. But I won't. If I can do That, I'm sure you can do this.

Subscribed.

Ok done for day four, i need some sleep face 24 fuselage and wings now sanded to shape, motor hatch cut out and servos fitted. Also ticked off the list are the aileron torque rods and elevator halves joiner wire, all bent to shape but not yet fitted., finally a bit of sheeting done on the rear underside of the fuz,

A couple of bits i could do with some suggestions on, the aileron torque rods are shown on the plan as having some household wire sleeving cyano`d into the torque rods and servo arm linkage, is this the way everyone else has done it? Hoping for some speed out of this with the Mega brushless motor, are they up to the job?

Also elevator pushrod, it shows it as just a piece of 20swg wire, again not sure if this would stand upto a bit of speed, it seems to flex a lot over it`s length, dont want elevator flutter at speed etc. I thought about using a small diameter carbon rod with the wire bound and epoxied to either end. Any thoughts in this area?

All help appreciated.

Mrs C is now nearing the end of book 5, War & Peace is next, she is going into town tomorrow morning for some fresh air before the marathon reading!

Good luck with the challenge. Hopefully the time covering the model won’t cause you to loose the race

Regarding the reading... Many years ago (about 30), as an up and coming young manager I was sent on a document assimilation course.. i.e. speed reading. Our instructor was a remarkable John Cleese double - although slightly shorter. We were shown how to take in (absorb) documents, one sentence, then a paragraph then a page at a time. Within 3 days my reading rate had gone from about 200 words per minute - which wasn't bad to 22,000 words a minute and I was understanding and remembering more. At the finale I read "3 men in a Boat" in 22 minutes and I can still remember discreet paragraphs of it now. We were tested on the book content - specifically events, names and places. It wasn't enjoyable reading and it was very hard work, headache inducing, but a useful skill to have.

I think I would prefer to build. Watching and good luck..

Martyn

Aileron torque rods and linkages, took a bit of working out and modifying bits that i had in my spares box. Bit of a setback, the canopy arrived from Sarik this morning but it is too narrow to fit the fuz, not sure if the canopy is too small or my fuz is too wide! Anyone know where i can buy some blue or pink foam on a Sunday!

\if you are just going to make a fake canopy you could use a chunk of white packaging foam ( if not too heavy) by sanding to shape with coarse new glasspaper and covering with brown paper ( etc) and dilute PVA. Overnight it becomes a smooth lightweight shape ready for paint. looks like balsa colour too.
