Both BigDave and Merriman have it going. Merriman has a custom WTC for it and fittings. That flyer should have been in your kit.
I'm waiting for mine to arrive with the fittings kit. This will be a long build and everyone else is taking there time to design their own method of RCing the boat. That's the fun in this model.
Don't worry. We will be knee deep in them soon. Just like the Gato. Every one it seems has a Gato except me. LOL!
Actually do, but mine is a little different.
