General Information

So... here we go... the latest model from Twisted Hobbys' and RC Factory. Not only is this the first twin to join the line up, it is also a seaplane AND designed for 3D flying styles.

If you enjoyed playing with all the radio mixes on the Crack Beaver, you will be in Heaven with this one, now you have left and right motor thrust to add in! If you are not savvy with mixes, no worries there will be a post and section in the manual on how to do this .

Being a seaplane, it is likely that it will spend a lot of time around water, this being said there will be a couple additional / optional steps to perform if wanting a robust and waterproof set up. This will include steps on how to waterproof your electronics as well as building techniques that will minimize the water absorption by the EPP airframe components.

Given the power to weight ratio obtained with the Twisted Hobbys Power Combo, you don't necessarily need a puddle of water for take offs and landings... the Puddle Star is quite at home on the snow or grassy surface. If you are real adventurous, this being a twin and having clear sight off the nose, the Puddle Star might just make a good FPV platform as well. Once the build is done and the Twisted Hobbys' PDF manual published, we will have a look at the possibilities if no one else has yet.

Check back often to theses first couple posts, especially the Build Part 1 and Build Part 2 posts, over the course of the next week or so there will be lots of new content added on regular basis.

Enjoy..!

Build - Part 1

Part 1 of the Build Photos and Comments

Before you get started, consider how much exposure the Puddle Star will have to water. If you plan to spend a lot of time on the water, a more robust "waterproofing" (waterbug) build would be in order. If you will only occasionally fly off water, standard (grasshopper) build procedures are sufficient. Both methods will be discussed in the build thread.

Aside from the need to waterproof things, this plane uses all the same tools, glues and basic techniques that a standard EPP foamie would require.

The additional supplies to build the Puddle Star are;

Grasshopper Build
  • Approx 36" of 18 to 20 gauge wire - see note below
  • Six sets of 2mm bullets (six female and six male) - see note below
  • One roll of 1.88" wide standard/thin packing tape - hardware store
  • One roll of 1.88" wide HD packing tape (3M or Gorilla Brand) - hardware store
  • One can of 3M Contact Spray Adhesive - hardware store

Waterbug Build
  • Approx 36" of 18 to 20 gauge wire - see note below
  • Six sets of 2mm bullets (six female and six male) - see note below
  • One roll of 1.88" wide HD packing tape (Gorilla Brand) - hardware store
  • Approx 60" of 12" wide 1.5mil thermal laminating film - print shop or eBay
  • One can of 3M Contact Spray Adhesive - hardware store
  • One can of Plastic Dip or Liquid Electrical Tape - hardware store

Note - Extra wire and bullets for the extension are ONLY needed if you want to bury the ESCs within the cabin area. If you waterproof the ESCs as described there is no reason other than "cosmetics" to bury the ESCs inside the cabin area.


Having trouble locating 1.5mil Heat Laminate?

I did discover today that at print shops where they do laminating they are not always able to use the very end of a roll in the machines, and if you sweet talk them, they might be willing to donate the "scrap" to a good cause. Otherwise you can also get the 1.5mil laminate in smaller qtys off of eBay



Waterbug Build Notes

It should be noted that if doing the Waterbug Build there is some inherent risk when applying (ironing) the 1.5mil laminate material onto the EPP foam. LOW temp settings on the iron are a must. Experiment on a small area or piece of scrap before jumping in. Any damage to the foam is the builder's responsibility. With that said, if you do plan to spend a lot of time on the water with the Puddle Star, the extra efforts of the Waterbug Build will be well worth it.

The laminating process takes a little time, but is not difficult at all. Just make sure that you are using 1.5mil heat laminate material, that you have done a test piece to determine iron temperature AND as mentioned in the build.... the laminate shrinks a little, so take this into account when applying to the foam, start from the center and slowly work towards the ends, this will allow the film to shrink and will minimize bowing of the parts.

It should also be noted that it will be obvious when you get your iron's temperature correct, the laminate will have a very robust bond with the foam, if it is not, then turn up the temp, BUT as mentioned (more than once) do this on a scrap piece of material, EPP has a pretty low melting point and is easily damaged with too much heat



More building fun to come.. !

cdee, canīt wait to see how you handle this!
one small note, I believe that the electronics need no waterproofing.... whatever bad things we have done to the prototypes, the electronics never got the smallest drop of water on it.
