Hey Sonny

Thanks for the A123 dim's I will do some drawings and see how they fit on my frame.

Great looking frame you put together there how did you cut it out looks very well done.

I love doing mods to Helis that make them better serve your needs

Can i make one small observation regarding your battery pack construction.
hope you dont mind me pointing out but the negative connection on your 2cell "hump" pack has insufficient solder in the cable. The bare copper wires can be seen and they should be filled with solder i am afraid that with the high currents possible with A123 cells you may have a problem there. I would suggest desoldering it and carefully tinning the cable then resolder to the cell.

Hope this helps

Ben

Wazzer,
What a great design.
My bet is it would be the best selling aftermarket frame.
It does have all the best of all the others and no downsides.
Love to hear more

You are absolutely right !
In fact, le solder broke just after I put the bleu cover !
So I resoldered it with plenty of solder, I can tell you it won't break anymore !

You have a very good eye anyway !

Default Where do we sign up 4 frames?!

Wazzer, that's excellent work!!! I have my roadmap all figured out: flybarless, all metal head, Wazzer frame.
This is truly a gadget sport! And I haven't even flown yet!

I have worked with CAD in my younger years so this stuff almost makes me relapse! Now, where did I put that installation CD...

Regards

Heh Ben,
Fantastic work there mate. Where do you get your acrylic CNC'd ???

Oh and thanks ...now you've got me thinking about custom frames for my blackhawk project.

Sodster...download google sketch up ...you'll love it and there's loads of tutorials on the web...
It's slightly different from classic CAD design programs but once you've got used to it it's so much faster and simpler than anything i've ever used

Cheers

Hey Big Fil

I have a friend in the sign making business who also flies Helis and they have a pretty big CNC table router. The acrylic is really easy for them, but when they cut carbon fibre its not as good as thier machine struggles abit. The edges are a little rough but nothing an hour with a file cant sort out.

I also have a friend with some really big HAAS / HASS (?) cnc machines who is making some other parts for me.

Your written english tells me you might be an Expat in Singapore is that right?
I dont live all that far from you in Kota kinabalu in Sabah.
I wish we had the hobby shops you guys have over there....although on second thoughts i would be very poor!!

Yeah Brit working here for nearly 13 years now. Did a lot of work in Brunei in 97 98 and some work down in Tengarong ( spelling) in 03. Been to KK only once years back on holiday to Sepilok. Cool place. At least you have plenty of places to fly. Singapore's filling up with concrete fast!

Signmakers ...cool idea ....I've a few contacts here ...mmmmmh could be fun.
Carbons a bitch to machine. Cutting tool speed etc. Apparently it depends on the resin type used in laminating the CF cloth. All heat related issues. But like you say bit of work sorts it out.

I've been using poly carbonate for roofing design and it's more expensive than acrylic but bullet proof ( literally). Apparently it machines like acrylic so might be useful

They've got the lot

Cheers

nice ben really looking forward to those pics and subsequent flying reports! i really like that frame of yours- it's great in its simplicity and seems functional. have you thought about cog issues?

Default New Component pics as promised

Hi guys

Finally recieved the new components from my friend with the machine shop.
Please bear in mind these are PROTOTYPE parts and are a little rough looking
I told him not to worry about the finsh. They are actually better than the pictures show the camera picked up every blemish!
I have already redesigned most of the parts so the next bacth should be even better.

OK first are some pics of my new motor mount and frame stiffener combo.

As you can see my new motor mount allows for really easy adjustment of gear mesh and motor removal. There is a simplelate that bolts to the motor using countersunk screws and then this is atached to the motor mount. The motor plate can then pivot around one bolt on one side and is secured by another bolt in a slot on the other. All very simple and very very similar to that found on the E325 Mini Titan

I am not yet 100percent sure but i maybe able to fit this new motor mount to existing Hurry frames with the standard servo layout although there maybe some clearance issues with the servo linkages to overcome.






Next you can see the full size Spektrum DS821 Servos installed.
Once i install the correct length servo arms they will line up perfectly under the swash.
Any sub standard size servo's such as the S9650 can be easily fitted with an adapter plate.






In this picture you can just about make out the new main bearing block with Full Size main shaft bearings for the OWB shaft, along with a matching ful lsize bearing in the lower OWB shaft bearing block. This replaces the much smaller slim OWB shaft bearings (the ones that always fail) with decent size bearings.




As soon as i recieved the parts i could immediatley see how i could improve them and make them easier to machine. Its funny how holding something in your hand makes a hughe difference compared to 3D modelling on the computer.

I am now waiting for New the revised Frames to arrive so i can assemble it all properly. Unfortunatley he is awy for another week or so.
I decided to have the prototype frames machined from 3mm Acrylic as opposed to the 1.5mm of the ones shown in the picture that way i will be able to test fly the heli before i get the frames cut in Carbon.

Any way guys i hope you like

please feel free to comment i welcome any good ideas for improvments.

Cheers

Ben

Impressive work there. I would definitely want one.

How many would you have to make/sell to make a production run worthwhile?


Maybe a list of potential buyers would give you some numbers to work with.

Hey guys thanks for the comments

If you guys think its worth pursueing then you will have to let me know how much you would be willing to pay for it.

I would see the full kit including
New Frames
New Motor Mount
New bearing blocks

I could also sell the new parts separately.

I would imagine the Full kit with Carbn Frames plus all new aluminum components shown would have to be sold at roughly $200USD to cover costs plus a small margin.
The lower the numbers the more expensive it becomes and vise versa.

I would really like to be able to produce these frame conversions even if I only make enough for a couple extra battery packs from each batch I would be happy.

Let me know what you guys think.

Perhaps we could put together an order book and see where it goes.
I would imagine I would need at bear minimum 10 firm orders to make it worthwhile the machine time alone costs a small fortune as you can imagine, plus the materials.
By the way the aluminium is 6063 with T6 heat treatment.

Cheers guys

Ben

Hey Marco

I had already thought about making all the bearing blocks from one piece but it makes the machineing process much more complicated. To keep machine time down to a minimum all of my new redisgned parts can be machined in one pass. This means you dont have to remove the component from the machine turn it around remount and then machine again. Unfortunatley the machines that could do that type of thing automatically are not available to me locally.

What i can do though is to make another brace that would connect the two bearing blocks together to add even more rigidity and aid with bearing alignment.

I will have a think about it. Although when the side frames are made from 2mm carbon fibre they really dont need much more stiffening.

Cheers

Ben

OK after a few minor alterations

I am very happy to say that the New Motor Mount will also fit a standard frame Hurry (plastic or carbon) with servos in the standard locations

Photos show a Z20 980 Motor and Cheapo Maxwell Servos

Version two will fit like a glove!!

I am sure that this could be a pretty good seller on its own with the stiffener included.

Cheers

Ben
