KK check out this link of the thread on soda can nose bearing.
I think even non registered guests can access it.

Useful to have a Jewellers’s nose plier - the one with rounded jaws to do such work.

Some pics to explain what I did to make a nose bearing from a soda can ring

This can be a viable alternative for the nose bearings that are being sold from the US.

Some more on Soda Can Nose Bearing

Some pics to show weight of the bearing and a comparison of size and weight with nose bearings made of aircraft aluminium I got from the USA that are used in used in F1D , Penny plane and Science Olympiad models.

My bearing compares well with them in terms of size and weight.

Making nose bearings can be a separate topic but since it is used in rubber powered models being on this page is useful and relevant.

Saw the details on hippocket. (I’m a member there too Grin)
But I fear this level of work is too fine for my capabilities.
(My daughter used to make books with written content and a stitched spine, the size of a thumbnail!)

I’ve only recently started on Peanut Scale...

Must get into scale FF models too. They are time consuming to build and need attention to detail. Some of them can also be difficult to trim to get decent performance. Nevertheless a good finished scale model with authentic colour scheme is a work of art.

Like the offbeat designs like Iambus.
Can you post the plan link — on Outerzone??
Check out the offbeat designs / plans of models by Bill Brown on HPA.
I have posted pics of his Yvette rubber power. An ideal model to convert to capacitor power. There is a topic on this in HPA.
My BOBNI awaits full power trials in a suitable space.

Thanks. Truly good videos, specially the jet landing not needing any net after all, but always be safe. Also loved your living room rubber powered scale flyer. I do that home too before I can get to the field, cannot resist.

You have a great flying field. Happy for you. A bit envious about that (..just joking). , my RC field is 3 miles away and my FF field is 40 miles away. So I fly FF at the local town soccer field/s. Have to fly at dawn and out by 8 as when kids come in.

Here is my soccer field video.

We have a new airfield, but posting that here would divert this thread too far afield...

Hi all
Back after a bit of an haitus.
Check this link for some useful info on wing design.

http://www.razvanapetrei.com/reasons-behind-the-shape-of-aircraft-wings/

By the way has any one used “Paulownia wood”.
It is also very light and very stiff and strong. Heavier than balsa but much stiffer. Ideal for fuselage of catapult gliders and other categories.
Got some sample sheets from a China supplier.
Sheets I got are 1 mm, 2 mm and 3 mm can get other thickness and rods dowels etc.
Used for boats models and architectural models too.

Hi all,

Managed to get back to doing a bit of construction.
This one is a old design. A delta flying wing model called the “Flailing Arrow “.
It is a torqueless and tailless model.
It has two props - front and back and the elevon runs the whole length of the trailing edge.
Have use “Paulownia wood” for all components.
Some pics of the build. Fuselage stick, props and elevons to be added.
Will post better pic of plan.
I think it will be a challenge to trim it for stable flight and get satisfying duration.
Await further updates.

Hi
Build getting along well. Prop blades put on cylinder for getting helical curve.
Covering done with very thin grocery bag plastic.
Glide without props — only motor stick with nose weight seems good.
Will post pics

The Flailing Arrow completed
A bit of jugaad for the prop hubs, used the Ikara prop shaft and hub cylinder, did not have the nose ring so tired it down to motor stick. not too neat but does the job well.
Test flights in drawing room quite encouraging.
Full test flights in indoor space asap.
Some pics
