    Hi,

    After my last hair brain scheme to simply tape a digicam to a Estes Big Daddy, I decided to build a custom airframe.

    Find the full details here.

    All I had lying about was some 40mm tubing, thus why it is stuck onto a Big Bertha. Plans are afoot to build a D powered lifter :)

    If the wind ever lets up, I'll fly it and post video (If I recover it - and it actually lifts off the pad).

    Steve. South UK.

    Wow. I am impressed. Looks like a retro rocket from the 60's :D. Let me know how she works out :D.

    I'm reminded more of the V2/WAC Corporal stacks launched in the 50s: two different-looking rockets stuck together and sent up. Can't wait to see pix of both launch and in-flight!

    Very nice Steve, there's meant to be a heat wave (in UK anyway) next week so you might have the chance to fly it then.

    Good luck!

    I'm banking on that heatwave too. My Drake is itching to go skyward, but has been grounded by the $%^&$% weather!!

    I must come clean; its my fault, the current bad weather. I brought a pair of shorts for work, at M&S the other weekend - and the skies opened! :rolleyes: Just to rub it in, I must have drunk so much beer / eaten so many packets of crisps/pot noodles, over the winter; they don't fit!! Time for a diet, me thinks!

    By definition, a Big Bertha is retro. :kill:

    Very nice. How much does the unit weigh? Be sure your booster
    can take a large enough motor that the pictures look interesting.

    Thanks for the supportive comments :)

    I have finished building the new D powered stage to replace the Bertha airframe. This will be primed, painted and flown later today. At last there is little or no wind and it is sunny here in the UK!

    The cam stage weighs in at 135g the whole rocket wieght inc. recovery and motor is 190g

    I'll post news and photos as I get them.

    Steve.

    Good idea. You dont want that camera crashing. And even if it didnt...The D12 will allow for better pictures.

    Ok, flight time is nearing :)

    The new D powered shorter stage is finished, recovery devices added. Should get altitudes of 500+ ft :)

    The electronics have been added to the camera. If all goes well I should be flying this thing later today :) Just hope it all works together. If it does I'll post the pics, but only if they are not blurry messes ;-)

    It flies! Straight and high with a little arc over so the lens points down. Pics were taken but lost on the way home? I will be adding a switch to turn off the timer. At the moment I have to fumble about with the magnetic battery clips.

    That looks amazing
    What timer did you use or did you make your own?

    How much did all that set up cost?
    Including the camera

    But i do suggest you use a larger engine F would be good or G (maybe)

    Look really kool though

    Hi.

    Costs so far have been (Camera and eletronics only - I had materials to build airframes etc).

    1 AipTek PenCam Compact VGA 64MB camera: £16.80 (ebay)

    1 Dual LED flasher kit (LEDs and resistors replaced with a 12V micro relay) : £6.48 (www.maplin.co.uk)

    1 Mini 12V battery : £2.49

    2 switches : £2.00

    Total so far: £28.26 ($45.55)

    Here in the UK I can't find any larger motors locally and I think I would need a license, plus this is my 1st scratch built rocket. On a D it flies straight and high - > 500ft which I am happy with so far. Hopefully I will be flying again later today - this time I hope the pics stay in the camera on the way home!

    Steve.

    It flew ok, seperated & landed badly.

    All the details here.

    Still learning.

    Shame about the fast descent but you still got some nice pictures. With a parachute attached to the camera you should get some even better ones.

    Pinter,
    Would you be willing to post instructions to build your controller? I have been looking into this myself, and have been weighing control options. I also recently got a pencam on Ebay cheap, and will be assembling a suitable launch platform for it soon.
    There is a controller kit available for 35 dollars, but I would rather build myself if possible.

    Thanks, and sorry for you loss. ;) Nice pics, by the way.

    Anyone got an idea of the size of chute I should use for the camera section? I currently have a 24" chute with no spillhole. Is that ok to give me fairly slow descent (stage weighs 190g).

    Thanks.

    Steve.

    Using the parachute size calculator on EMRR, your 190g rocket would need a 24.3" chute to descend at 3.5m/s which is about the right speed.

    I will be cobbling togehter some instructions on how to make one of these things.

    Here is a 3D exploded view. Soon I will have complete instructions ready.

    I used 3D MAX 5 by Kinetix.

    Could have used illustrator, Corel etc, but I need this at different angles.

    Rocket Geometry is simple enough to make the job fairly quick to do.

    Holy Mackeral!

    If this is "cobbing together" something, I'd love to see what happens when you try hard. Nice pic, Pinter!

    Hi,

    Ok launched it again, The D12-5 ejection is still causing havoc, tore the chute! and managed to loose the booster stage :-(

    No big deal as I need to make a longer booster stage to pack more wadding in. The cam stage still survives - it's the way I build 'em ;-)

    Here is the best shot from the flight - kinda arty.

    Find the rest here: 2nd Flight
