An jazzy new feature to our website..

I added an new feature to our website. It is an plane finder. It is really an collection of links to specific plane pages. The idea is simple. If one is seeking let’s say, economical planes they are collected into one category. And if one is trying to find large scale gliders there is also an category for it.

Plane finder can be accessed from to navigation bar via button marked with ‘?’. Great. Let’s see how this works.

I also added buttons for reaching this blog. I have always been wondering how it will be found, hope this helps.

And grabbed some nice vintage plans & kit.

Redigo contd.

Next step is to add fuselage formers. There are couple ways to do it, I tend to do free-form-spline-way as it allows most control to form. You could also utilize built-in-former definitions but they are useful only if you are doing non-scale plane.

I also tend to use scale positions of formers. Occasionally it results too ‘dense’ structure, but normally original design team has had something in their mind while drawing formers to places specified in factory drawings. So to save thinking I just copy that process.

Using original formers is quite easy if you use most complex way :). This is really curious, as anything easier is actually more complex. Go figure it out. You just import piece of original drawing and draw devfus former around it using control points. All sheeting etc. stuff will come in later stages.

From experience I have found out that there is no point in trying to get too close in this first iteration. Because next I must revert earlier stage and iteratively fine-tune top- & side-drawings. Now I can start peeking 3d-approximation of of design. And then go back and forth. I did tail section formers, next step will be front fuse formers.

Redigo…

Oops.. I just forgot to add one thing. This will be drawn to 1:6.67 size, due the nice feature of this design. It shares canopy with L-70 Vinka. As an lazy person I really do not want to make second canopy mold for this plane. So to save time and effort it will be same size as my previous project.

And then to next project. This has been requested so many times that it makes me hurt. Plane in question is Valmet L-90 Redigo. It is an continuation of L-70 Vinka/MilTrainer. The development of this plane had it’s complications. First Valmet decided to add an turboprop to Vinka. After some iterations they designed an L-80 Turbo-Vinha, which has some looks of Vinka in tail section. Wing is different and cowling is totally different to house turboprop motor. Also, L-80 had retractable landing gear. As you might remember Vinka means cold wind from north, so logically Vinha (note h) means just fast. I do really love Finnish language… Sadly L-80 crashed killing pilot Paavo Janhunen. So back to drawing board. An number of modifications were made to tail section. First, sideline was slightly raised at tail. Elevator was moved slightly back and rudder was completely re-designed. New design was named as L-90 TP Redigo. (TP=turboprop) This plane was quite successful, they built 10 for Finnish airforces. And surprisingly 30 was built for Mexico and Eritrea (!). Then at 1996 manufacturing rights were sold to Aermacchi at Italy. Which has continued to manufacture this plane with designation M-290.

Then to modeling of this rather sleek plane. I was granted right to use original manufacturing drawings of this plane from manufacturer, Patria Aviation (the current incarnation of Valmet). Great many thanks for Patria Aviation’s support for modeling hobby.

I received an pack of plans containing excellent general drawings of L-80 and tail section of L-90. Then also an set of slightly worn out manual drawings of plane. Tail section of L-90 drawing did not contain rudder. So to get this started I had to merge L-80 front and L-90 tail and then rudder from manual pics. … Slightly complicated, but finally I managed to get it more or less ok. You might notice some visible marks of this process in screen captures of this blog.

Next I utilized my normal set of tools, namely DevFus to get fuselage outlines done. Current fuse status below, this needs plenty of fine-tuning, but it is an start.

Nothing happens?

Hi ya all.

It has been awhile since last post on this blog. I have to admit that I got slightly annoyed by constant bombardment of spammers to this blog site so I shut down all commenting, removed (hundreds) comments selling italian bags and shoes etc. The commercial side of this enterprise has continued with no problems.

We have introduced an number of new designs. Most interesting has to be PIK-26 Mini-Sytky range. The initial one was 33%-sized one which has wingspan of 1.74m. Quickly followed by 50% one with span of 2.60m and 17% one with span of 0.86m. As one clearly can see the original plane was rather small. It was designed by mr. Kai Mellen with first flight performed in 1996. So it is quite new! This particular plane has been built several dozen times in such far-away places like Argentina and in Europe in Germany, Italy etc. Obviously also in Finland where there is 4 planes in registry. The designs are currently in pre-announcement mode, that is the plans are available & orderable, but parts are still being tested and prices calculated for cutting. One thing worth noting with Mini-Sytky-range is that the design is based on original 1:1 plans. We have taken painstaking care to make only minor changes to design so the model aeroplanes are almost identical to original planes. With the exception of size. There is an design blog (in Finnish language) in lennokit.net.

We have also added prices for several new Harakka’s in 33%-range as they are really ready for ordering. Also an new addition to our free plans section is an motor-pod specifically done for 33% Harakkka’s.

One thing which has caused quite a bit of work has been updating of galleries. They are crucial for building scale planes as these planes in general are quite rare and even more rare in global perspective. You can go to an Finnish airport and spot one, but you cannot probably find them elsewhere. I am quite proud to state that currently we have most broad and detailed photo gallery of PIK-range planes anywhere. It is an product of couple years of walking around museums & airports and digging into old barns and sheds. For space constraints I have compressed photos to smaller size, but if you are in need of hi-res pictures pls. contact us. We are happy to share pics of these classic planes.

Continuing to new models. Currently under wraps there are PIK-21 Super-Sytky (yet another sytky-design…) and Valmet L-90 Redigo. There is initial research for VL Myrsky II and we are still trying to locate usable set of PIK-5c plans.
