Mini Tarka (oz10385)
About this Plan
Mini Tarka. Radio control sport model, for .049 power and 2 functions.
Quote: "Fancy a spot of small-scale pylon racing fun? Then try David Boddington's Mini-Tarka.
It all started as a joke! Having recently introduced Club 20 pylon racing, which caught on right from the beginning, I was being barracked by the 1/2A pylon enthusiasts. These lads had been struggling along with the .049 powered pylon models and were at the stage of modifying the engines to gain a few hundred extra rpm. The results of these mods were to have unreliability in engine runs and, not infequently, bent con-rods. In an effort to get a 'non-engine tuners' class, that could be afforded by any modeller, I decided to promote the Club 20 class - what has happened to this racing in the intervening years is another story.
With the criticisms that I had 'killed' their 1/2A racing (although most of them took readily to Club 20), I decided to turn up at one of the races with a 1/2A type model: What the b... h... is that? I thought you didn't like 1/2A racing? I had to admit that it wasn't a serious racer - just a fun machine, and that is exactly what it is.
For you? Any good .049 engine will power the Mini Tarka; if you want to fit a radial mounted Cox engine the bearers should be omitted and the front bulkhead position adjusted to suit the length of the motor. The front cowling will have to be made separately. You could use a PAW 80 diesel, spacing the hardwood engine bearer to the required width.
Designed for two-function radio only, you will need to use miniature equipment, but it is not necessary to go to sub-miniature servos. A 225 mAh or 150mAh nicad should be used. This is a one-piece model and access to the radio equipment is via a bottom fuselage hatch. Draw the position of equipment and servo bearers on the plan.
The undercarriage is optional and not, in truth, too functional - with no rudder control for take-offs. It just looks nicer with a pair of wheels, particularly when spatted.
Start by making the wings. These are constructed flat on the building board, over the 1/32 sheeting. Add the leading edge..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsG'day All I hope this finds you well, I recently built a DB Mini Tarka and thought you'd like a pic of it [pic 006]. FWIW, it's powered by a McCoy 049 Diesel swinging a 7 x 3 MA Prop, it flies beautifully, is reasonably quick and it flew straight out of my hand. Thanks for all you do on Outerzone. Cheers from Hervey Bay, Queensland, Australia.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
