Hi All,

Been putting a lot of hours into this over the last month. The latest from Richard, who as he was busy with other projects asked me to build the prototype model from the basic plan.

Tipsy Nipper for rubber, CO2 or electric. I believe Pete Smart is adapting it for radio as well. 1/12 scale, which still only makes it 20" span. Scale structure: the bones in the pix stand at 20.5g, so i'm hoping for an all up around 45g, which will give a wing loading of 9.7g/dm2 for rubber power.

It's likely the plan and associated article will feature in December's Aeromodeller, together with a reprint of Ron Moulton's 'Aircraft Described' article and drawings first published in 1959.

What a lovely model Graham and at a very useful size. I have one built from the Aeromodeller Mk 1 free plan using a Dart that flies nicely at 6 oz. The plan stated 8 oz that would have been very exciting in terms of flying speed. It would probably be better with a smaller engine.
 It is very twichy directionally, and was not consistent until I used a 6x3 prop to tame the left turn under power and allow a reduced rudder setting for the glide turn.

Always loved the Tipsy Nipper. I made a peanut version as a teenager, complete with bodged tail lettering and an ill fitting plunge moulded canopy. One of my first attempts at own design. It never flew, and fortunately no photos survive. I did take it along to one local indoor meeting (where I think my dad was helping Doug Sheppard officiate). Someone weighed it for me and the only comment was, "Woaaah, that's heavy!"

This version looks somewhat superior!!! Greatly looking forward to seeing more and to the AM plan.

Thank you Pete for giving me a good laugh  Cheesy Cheesy Cheesy


Hi Graham, it looks great !

Do the upper lg legs slide into the fuselage for shock absorbtion?

Looking forward to seeing the plan/article in AM. Even if it's something that never gets built, there is usually something to learn from studying any plan.

Cheers,

Dan.

Thanks guys for your kind comments.

George: no, the main gear is rigid, the ‘wood’ coloured legs being 1.5mm diameter bamboo. If you look closely at the front threequarter photo you can just see that the bamboo legs are linked side to side inside the fuselage by light 1.5mm balsa web plates. At the axle end they are epoxied and thread bound to the wire inboard leg, forming the inverted tripod u/c. Richard has found this to work well with tricycle undercarriages: the nose gear takes the landing impact as the model doesn’t flare and at best lands flat. Consequently, the nose gear is torsion sprung inside the fus in alloy tube.

The full size has the cowl cheeks slightly filleted into the main cowl. I’ll do this with a small amount of filler.

Covering next!

Ok, someone remind me: why does Apple think we all like to look at photos upside down? I took the last set on my iphone, imported them into my PC, rotated them 180 degrees when i found they were inverted when opened in MS Office, then posted them here. I’ve now checked them on my ipad and they are still showing as inverted!

Probably because the ipad thinks i’ve turned the images upside down!?

I read up on this.

"Up" is with the buttons at the bottom, but IIRC Apple thought that people might like to use the buttons to zoom so, if you take a picture that way up, your phone "knows" that it is the right way due to a little instruction in the file...

I think when you process them the file gets ignored somehow...

To cut a long story short, take pictures with the buttons at the bottom.

Super BTW!  Grin

Thanks to the guys for getting HPA back up and running!

In the interim, the Nipper is now pretty much complete and early glide tests are promising. Expected all up will be around the 42-45g mark so a wing loading of approx 9.5g/dm2. Lots of masking and many hours later...........!

Many thanks all.

Dave Banks’ superb pilot sets it off, and i have derived a major advantage in that OO-WOT is the primary subject aircraft for Richard’s article in December’s Aeromodeller, but it did take a considerable amount of time and copious amounts of Frogtape when i airbrushed it! And more than a few naughty words too.

Thanks again! The scheme is a mix of airbrush and laser decals, the latter being the black fus side flashes and fin codes, both of which are doable with masking but were kindly generated for me by Richard, as a result of his artwork for Aeromodeller
