Who else hates the Bitchler 2 and what is $ Tree Foam?

[mrwilljackson]

Hi guys, I've built one of Eds photon motor gliders from 6mm depron covered with tape. It flies really well on a 2200 3s with a 1100 kv motor. I'll post up detail pics tomorrow so you can see how to make Eds techniques work with out $tree foam. I'm hoping to fpv with it this weekend if the weather behaves.

Get your 6mm depron from kudos trading on eBay, tape one side of the sheet as per Eds instructions. You just have to cut channels, or compress the foam to get it to bend around a tight radius, simples :)

I'm also thinking about a peace drone!

Cheers Will

Hi Will

Thanks a ton! Please post pics here, I'll be very interested to see how it worked.

Just to be sure, is this what you used? http://www.ebay.co.uk/itm/Depron-6mm-White-1000mm-x-700mm-7-sheets-BNIB-/250494862011?pt=UK_ToysGames_RadioControlled_JN&hash=item3a52a842bb

Cheers

Sorry to be a nanny, but I cant see anything in this thread that has much to do with gliders and scale planes?

Thats the stuff - the sheet size allows you to make all of Eds designs with some to spare! Don't bother buying any uk 'foam board' its waaay over priced in 'art shops', you can't get the paper off it (easily) and you can't get the US version $tree anywhere in the UK. Once you've taped up the depron it works for all of Eds techniques for building wings and fuselages etc...

pics and a LOS vid of last weeks flight coming today... watch this space ;-)

Cheers Will, looking forward to that! When you add it, please mention the approximate build time etc, any quirks you had and what not? I may try and squeeze in an FPV Peace Drone with 360 servo, flight cam, Go Pro, OSD and AP before the meet on 1 June with the remaining bits of the month between two overseas trips, training and my nagging clients :)

Got it! Thanks for pointing that out  :)

Here goes  ;)

Experimental Airlines Photon, built with Depron and Packing tape.


Tape over the whole of one side of a sheet of depron before you start cutting, marking. Ed has all the tips on doing this on youtube.
It helps if you can cut bevels neatly to different depths, I'm not good at this free hand so i got one of these things which seems to work really well against a angle aluminium straight edge:


Fuselage Tubes
For the fuselage I needed 1.5 inch (internal dimension) square section. SO marked up the length of depron as shown below:


Then cut two bevels adjacent to each other, about half the thickness of the depron. Sounds tricky but with the angle cutter thing its dead quick and accurate.


use the straight edges to gently fold the fuselage into a square section btw the tape is on the outside ;-)


Then cut a strip of depron with tape on one side and gorilla glue this to the join - makes a very solid tube indeed. For motor mounts or general strengthening in specific areas I've put depron inserts at 45º and glue a plywood firewall (5mm seems to work), self tappers hold my motor in place.


In order to join longer lengths of fuselage i've used a depron I beam so wires pass through and the join is true and rigid. I think the Ibeam is around 15cm in length.


once taped up you can cut and glue up fuselage tubes quite quickly, just need to leave the gorilla glue overnight, clamped down (again as per Eds videos).

Wings

Again with a taped sheet of depron you're good to start marking out. I made 5 inch wing chord with 1.5 inch ailerons.

mark out from the trailing edge of the flat bottom surface (not the flaps) for the wing chord you need. Then cut three bevels to allow the depron to bend around to create the LE. Other people use lollipop sticks to compress the foam to allow it to bend- this might be much quicker than cutting bevels?

Ed uses two thicknesses of material in his wings, I couldn't get the depron to bend nicely over that much, so i've used one thickness and a carbon spar (from giant shark i think) 6mm dia. Maybe with larger wing chord you could get it to bend over two internal formers.

Cut the TE of the flat section so that the curved top surface has a flat area for your hot glue to hold the wing together.


Finally cut the bevels to create the aileron hinges and trim off the ailerons to the size you want.


The spar fits well and is a snug fit inside. use another one to push it out of the wing - you can see the centre section of my wing folded below, with two spars and the servo leads coming out.


Tail feathers
One side taped depron sheets cut to shape, bevelled le and hinges, then tape the remaining surface and you're done. Simples!

Putting it all together
Ed uses gift cards - I got some blank ID cards from ebay, and I recommend his technique for attaching the rudder and elevator. Makes a really strong assembly.

Electronics

2200 mah battery fits next to the 30A esc, all balances nicely, I need to add some down thrust to the motor but aside from that I'm pleased.

tape - if anyone knows a good source of tape, I bought various colours from an online packaging supplier (cheap!). Some rolls have remained really flat and well stuck to the depron on the wings, but the white stuff on the fuselage has bubbled quite a bit - no idea why!

Overall - I spent one evening taping a load of sheets, one evening to make the fuse, one evening wings, one evening tail and overall assembly.

Any questions - fire away - Eds videos are really good btw!

Hi Wil

Thanks a ton mate, that's pretty comprehensive! Your plane flies very very well and I think it would make a great FPV ship! Your build pics are also very good and I will visit back here for tips when I start my own. I like the look (and name) of the Peace Drone, so I think I'll do one of those for stability.

I also watched the Wayne's RC Video - he's definitely got it all down to a T!

I've ordered my Foam Board today, was about £24 with shipping for 7 pieces 1m X 700 I think.

Thanks again, please post up FPV vid when you got it! :)

Super clear 'how to do it' post Will.....

Karma point from me for putting it together so well  :)

Yeah Paul, I gave my Karma point anonymously, but now I'm gonna sing it from the high mountains :) Haven't you done some scratchbuilds in your time Paul?

[FPVSteve]

i gave one too, not a bad run! lol

Will if you make it to the Oxford meet on 1 June I'll cover your entry and lunch. Come if you're available - we can make peace between Oxford and Cambridge :) Thanks again for this info. This has breathed new life into my FPV career.

Meet thread is 'Mad Dogs 3'
