Here are some pics. My friend "Stealth Vader" took the flying pics for me. I have an FPV setup on plane now.

I attached the tubes using 3-M double sticky tape with a bead of hot glue around the edges. I butted the tubes together with a 45 degree scarph joint, hot glue and then duct tape for good measure. Used a 3x3 and 3x2 tubes stacked on top of each other so the props would clear the ground when the plane was sitting upright. I used the 1x3 tube for the tail boom to save weight on the back end of plane for balance. The "UNI -flap" works out pretty well.

Is it just me or are all of these planes fairly heavy? I like to build planes in the 12 oz. (340g) range with 200 inē (1290cmē) wing area or so. Is this possible with these techniques?

Chris

Built the 'Photon'

I had a few pieces of foamboard left and decided to build Ed's 'Photon' motorised glider because it looked big and imposing.

Built it so that the fuse pulls apart into 2 sections and the wings fold using the technique in Ed's videos. It makes it much easier to transport.

Flew it with a 2200mah 3s batter powering a turnigy 2200kv motor.

Maiden flight was a windy day with winds of 24kph+ gusting to 35kph.

The Photon just cruised gently into the wind and I was able to hover it into the headwind for some relaxing flying...thanks for another great plane design Ed!

Here is a video of the maiden flight:

Nice flight! Love the long wings. It would be interesting to know the flight times of both Noob and Photon, run off of same sized battery. How much difference do those big wings make?

Thanks Goodkebo! I flew it again today in near perfect conditions. Wanted to see how long a 2200mah battery would keep the Photon in the air, cruised around at 1/3 to 1/2 throttle and after 17 minutes I got tired and landed!

I tested the flight envelope of the Photon with some loops, rolls and inverted flight and it passed with flying colours. Will upload the video soon.

Flew the Noob as well for a comparison, the Noob is much more 'fun'. Will tack on the Noob footage to the end of the video so you can see the difference.

Here is the footage of the flight:

The vert stabs are from a plain someone built or is still being built, he has not updated us in a while on it, if your there hint. the TB 2 features a folding prop and CF reinforcement and working rudders along with decorative stickers.

Flies really well. Nice job.

Question, could not help hearing the roar of the prop, what motor KV and prop size are you using?

Thank you.

@rcnewbieoz thanks, I think you will like it too, but when you maiden it be sure to have your high low rates set. The launches can be pretty squarely. and be sure to attach the booms securely to the wing spar, mrwest has a fine solution for doing just that, look him up on youtube.

Landing gear needs to be wider and mounted further forward. Here's a couple of mine for an example, they don't need to be this high, but it works well.
