The Andy Conway Tornado at 150% plan

Okay, the cat jumped out of the bag officially recently that I am going to be building a larger version of the Andy Conway Tornado. The initial plan was for a massive 200% scaled plan but the cost of the plan and parts printing alone made this prohibitively expensive. So after a chat with fellow PSS'er Andrew Meade, A 150% print arrived via Phil Cooke at a much more reasonable price!
This all took place around October 2017.. So with Christmas now well into the past, out came the plans and the special wood order went in to SLEC. Standard plans are cut from 4inch wide balsa sheet... So a simple calculation showed I would need 6 inch wide sheet! Luckily SLEC were able to accommodate this and before long a parcel of wood arrived! |

LOL! Hmmm. Think it will be done on the KISS principle... (Keep It Simple Stupid!) Fixed wing but I may look at droppable wing tanks for use on bombing comps! |

![]() 1851 forum posts 656 photos | Back again as promised! Time for some pictures! First is the arrival of the wood! and once unpacked..... That's quite a lot of wood there! The left had pack is all 6 inch wide and 5 ft long! Tx for scale!
And the wood lay over the parts plan sheet... Amazing isnt it how all that wood suddenly disappears over plans........ Well actually that's only half of the wood... To quote S.R.Hadden in the film Contact... " First rule of Government spending, Why have 1, when you can have 2 for twice the price!" Yes..... That's right.... There are 2x 150% Tornados being built! The second is to be built by Warren Phillips who I will try and encourage to do a blog about his (as he is doing the F Variation) So all that wood split into 2 nice piles... 1 pile per model!
But we only have 1 set of plans and parts sheet! No problem... Having cut out the individual sheets from the parts plan, these were then glued to one set of wood.
So there we go.... The parts process is underway!
Stay tuned.... More to follow!!! |

![]() 1441 forum posts 1016 photos | I think that fibreglass is the way to go Andy, and just remember, big isn't always better. As those 2 Jewish Men used to say in the sitcom "Never mind the quality, feel the width", but what was the title of the show? I regretted producing scale smaller wings as it needs a good wind to work. Presume you are adopting Andy's plan wing size. If so that is a good call IMO. Looking forward to the Orme. Will be staying with a Rugby friend who has a flat in Llandudno - sorry, a bit off topic mr Moderator. |

![]() 1851 forum posts 656 photos | Hi Peter, Wings! Absolutely.. Decided to stick with the plan wing.. although not a scale wing, It will allow a more favourable range of winds to be flown in! (Can always ballast up!) I did discuss wing section with Phil Cooke but decided the difference was not sufficient enough to change it from the plan to the more recently sported SD6060 profiled wings! So that will give the models a wingspan of 72 inches (6ft) or 181cm for the new age people! and a fuselage length of around 5.5ft. |

![]() 1851 forum posts 656 photos | Hi Ade, Glad to have you aboard. Foam or built up? The plan calls for a foam core wing and in keeping with the plan, this is what we will be going for. We had looked at trying to cut cores ourselves but really don't have the skill or equipment to do them!

![]() 1851 forum posts 656 photos | Thanks Andy but I think we will go with Cloud Models on this one. Once time, fuel & materials etc have been factored in its about the same cost and will allow us to continue with other parts of the build / keeping SWMBO happy! See you soon!

![]() 1441 forum posts 1016 photos | I know you have cut the plan up now Andy but I always make a copy of the plan via Mail Box then you have one to destroy on the bench and another to refer to whilst you are building. Just a little tip! |

Just a little tip! Evening Peter. Firstly... Who is Andy? I think a little confusion has sunk in here!!! So in relation to the "plan", its only the Parts sheet that has been cut up... Not the 3 view plan. That is in one piece ready to be built over! |

![]() 1851 forum posts 656 photos | Well I think its about time I updated the build blog as there has been a little progress since the last update! Here's some of the formers cut out with a 30cm rule to give some scale!
I did find one issue from the plans which was the fillets for underneath the air intakes..
No worries.... A lay over over the plans soon showed that the larger one was in-fact too big and it was reduced to match the smaller one! Panic Over!!!
First job of the actual build then was to join all the forward fuselage section base parts to create the fuselage floor and then glue a spine down the centreline onto which all the forward formers and nose are placed! Now the plan as drawn is for the F3 Tornado and I am building the GR4 variation which calls for a different shaped nose! After some careful drawing and scaling I had a nose outline I was happy with and cut this out of 5mm Ply. This is where I was upto yesterday and today, following a quick trip to a shop for some 3mm ply, I was able to cut and fit the wing seat strengtheners onto which the wing retaining system will later be bolted... (need to buy the parts for that soon!) So here we see the sides dry fitted... Starting to take shape!! Oh, The bench there is 140cm long and the fuselage upto now is 115cm long! She's quite a size! Current weight is 220g as seen above and I am hoping to keep the weight as close to 1.8kg as possible finished (although a little over isn't going to worry me at all!) Will update in time when there is more to tell! Dave

![]() 1851 forum posts 656 photos | Next little steps done on the Tonka! A quick trip to Webbies yesterday saw the purchase of the wing bolts etc... The fuselage sides were lined up, marked with the correct locations and drilled accordingly! Load spreaders were then glued to the outside of the fuselage sides where the bolt carriers sit and left to dry overnight! The eagle eyed will spot a lack of nuts on the bolts currently...... (I forget to get some!)
Anyway... This afternoon, the jig was set up and the fuselage sides where glued up and set into place and the jig tightened! This wont be released until tomorrow! So that's all for now! I was just a quick update on the latest little bits completed!

![]() 1851 forum posts 656 photos | Yeah, Yeah, I know..... Its taking some time to build!!! Unfortunately, due to work and family commitments including a 1500 mile touring caravan holiday around Scotland, The Tonka had to take a back seat for a few months however I am now back at it! So how is it progressing.... Well.... It actually took a step backwards initially..... Yes you did read that right......
At this point I turned my attention to something which would have been easier to do beforehand but hey ho.... The eagle eyed among you will notice the box is supported half way along underneath. This was just to prevent flexing and was made of some scrap balsa glued in.
Once the box was in and glued, blocks were added to the forward bottom and sanded roughly to shape. (viewable in the above pics!) Next, the blocks and top sheet were added to the area between F1 and F2 ready to form the area in front of the cockpit. (In time the forward part of the canopy will be seated here!) Once this was dry, Nose parts were created to fill out the nose ready for sanding. A template was made up to assist with shape and this was then marked up on the glued in blocks. Only one thing left to do now...... Still quite a bit of shaping to do but its well underway and you can see a nose in there now!!!
