3D printed 36" Northern Pike

I have been on another 3D printed model "36" Northern Pike". The thread on RCGroups is here.

It is a pusher prop configuration, and someone in the RCGroups thread came up with a mod to add a bungee hook so I will launch that way.

Quite an easy build, the wing sections in particular. They are keyed with dovetail joints that enforce proper alignment, then it is just a case of stacking the fuselage sections, one on top of another.

Airframe is ready. On to the motor and servo installation next.

Thanks, Tarek.

Just weighed it - 768g for the complete airframe prior to adding the motor, electronics and battery.

Flew it on Thursday - it was very nice. Smooth and plenty of power. I highly recommend it for a first 3D printed plane. Easy to print and assemble.

Stalled on takeoff on the second flight and ended up with a fair bit of blue and yellow confetti littering the snow. However, I really do like it, so number 2 is about half way printed now.

My printer has a 300x300x400 volume, so bigger than the size most 3D printed planes are designed for. I have merged a number of parts into single models to ease the printing and assembly. Fuselage now in three models rather than six, and merged four of the wing models into one.

Congratulations on the successful first flight Andrew. Hopefully the second model will have a much longer lifespan! Would you say these printed models are more fragile than our conventional wood or foam construction models?

Definitely more fragile. I am not convinced that they are really practical in the long term, but they are an interesting way to try out new designs. This model takes less than 1kg of PLA, so it will cost me about $25 to rebuild (PLA + glue), which isn't bad. I will be travelling this week so won't have time to finish it for the weekend, but otherwise it would be ready for mid week.

Hi Andrew from my printing experience I found printing 2 outline perimeter with 0 infill the model will be much more solid but the problem is you will need more powerful motor to fly the model.

That would be one way, but I am not sure I would like flying it with the extra weight.

In principle you can cut out damaged parts and replace them, but alignment could be a challenge. I did patch a few holes in the skin by printing flat sheets and gluing them over the hole. In this case i figured it would just be easier to reprint the whole thing. Combining the parts the way I have done this time means long print times for each job, but not very many jobs, and should be very fast assembly. I think that I will have 9 parts to assemble, and that includes two vertical stabilizers and two wing tips.
