Thread: Brushless upgrade super cub s

OK Simon, let's see if I can help any further smiley

First of all, please can you tell me the manufacturer of your Cub?
This will help me look up the specifications of your model.

Thread: Where are we with 3D printers now?

Thanks for the update Ian,, we installed a glass bed to our printer last week, also getting good results with that.
Well worth a try (also requires 3DLAC or hairsray for the initial layer to stick).

laugh 3D printing has some development to go before replacing injection moulding.

A quick Google didn't return any spares for the Malyan 180 (I checked HobbyKing & BangGood too).

They look like standard DC brushless case fans, so should be easy to replace.
I'm guessing 30mm?

Looking on eBay you can get '30mm case fans' from £1 (or £3 for UK stock).

Ian, when printing with ABS, try some of this on your bed, works well for me.

David, generally speaking, most printers will print with any filament, however the manufacturers will only recommend you use their own branded material (this is where they make the profit!).

The UP+2 is an enclosed printer and will do a good job with higher temperature filaments. Keeping the enclosure warm helps stop ABS shrinking, with PLA it doesn’t matter as it’s such a relatively low temperature material.

Choosing a printer depends on what you’re going to print and at what resolution/quality of a print you expect.
For example the Wanhao Duplicator i3 is an amazing starter printer for £289 delivered. The included heated bed and print quality you can get is amazing for such a cheap printer, where as something like the upbox is expensive but you get a nice enclosure and its quiet, which is great for ABS and Ninjaflex type filaments.

While the Wanhao is a bit noisy and not enclosed it doesn’t mean it won’t print ABS or Ninjaflex, as I said at the start, generally any printer, any filament.

No apology needed Josip, I added the link to try and keep us all together.

Purchased mine from here: Technology Outlet

Ready built, UK company, tech support provided and a 1 year warranty.
Printer also features a heated bed as standard, I'm a very happy customer, arrived next day too!

Download 3D models from Thigiverse or Easily design your own using free software like TinkerCAD

I'm finding best results are produced from Cura at the moment when slicing your model into layer GCode.

I converted an old brushed HobbyZone SuperCub to brushless a while back, this is a video of me flying it around on a perfect Summers evening.

I installed the mininum prop size as anything over a 8x4 prop is way too much power for such a light plane.

Always use a watt meter to check you are within stated tollerences below!
You may find that minus all the old brushed components you will need some lead on the inside of the cowling, so remember to check the CG.

Motor:
Model No: A22-15M / 1050kvm
Weight: 67g
Fit Prop 8x4 to 10×5
Current: 6A-16A (max 20A for 15 seconds)
Max Watts: 200w
Max Cells: 3s Lipo
LINK for reference

Motor also known as: KD / KDA / Keda / Dynam DYM22-15M

Recommended props:

Just learned about this from a Facebook post via Nigel Huxtable (Red Bull Breitling Team).
Terrible news, a massive loss to all and will be sorely missed in the Red Bull Air Race.

Red Bull said in a statement that the Austrian pilot died in a helicopter crash in the Alps.

The 48-year-old was flying back from a mountain hut in the Grossglockner area of Carinthia, in eastern Austria, when his helicopter struck a cliff late Thursday. A passenger was also seriously injured.

This is Hannes last Facebook post, only a few hours before the fateful journey.

Truly amazing Essjay to be able to navigate round the shop with just your mouse to move yourself around.
Holding down the left mouse button whilst moving the mouse allows you to turn on the spot.

I managed to make the pilgrimage to this shop earlier this year and took this photo.

It's well worth going out of your way to pay a visit, I was made to feel very welcome by Ali Snr, he even made me a coffee (a first for me in a model shop!). I was happy to find a well stocked traditional model shop, full of new and more traditional models, as well as few bargains tucked away at the back. Nothing was too much trouble for the staff, I look forward to visiting again.

For anyone interested in competition history, some of Ali Jnr's trophies are in there too in a few cabinets (must be at least 100 cups and medals).

A real Aladin's cave!

Awesome project and fantastic early results by look of things, well done Tony!

I would image there are some limitations as to how fast each EDF unit can speed up and slow down to maintain the hover. Looking forward to seeing how this progresses.

Sorry to learn that news, amazing contributions to the forum.

Great to see, I made it on Saturday and Sunday, shame about the wind putting so many off flying.

Harry and I had a great time flying the MXS-R & Pulse XT60

Will be back to Greenacres in August, see you there!

Heat from an ESC is not that unusual, however before you fix that you need to find out why the battery and receiver are getting hot, this should not be the case!

A hot (and possibly puffed) battery suggests you are discharging the cells too rapidly.
Do you have a watt meter and the specifications of the motor?

I would second iqon's suggestion of Weston UK.
They can custom modify or make to your spec.
