    Lipo size and UL-1 hull

    I was concerned that my current lot of 4S 2250mAh packs would not fit in the hull, but I am extremely happy to report that 2 x 4s 2250mAh packs fit in the hull with room to spare.

    This is good news for those of us who have a plethora of 4S 2200 packs from our planes/EDFs. I love the boat's layout... Simple and easy to work on. Kudos Grim/Aquacraft.

      Good to know. Its seems that there are quite a few options available for battery selection given the size of the tub. My 4S 2250s hold voltage REALLY well and at $46 each, I was super happy that they fit.

      Hopefully others will share info regarding what packs fit vs. those that don't.

        What are the dimensions inside the tub for batteries?...

        There has been quite a bit of discussion whether certain batteries will fit or not fit, it would be so much easier if someone just measured the inner dimensions in front of the motor mount. I am thinking of buying one.

            Thanks LuckyDuc. Do you have the length measurement too?

              The manual says that the packs must be less than 6"(155mm) long.

                  Hey, BTW, how's the boat running for you? Have you modified props, strut, etc.?

                    Actually you can fit longer packs in with ease. My 2S/5000mAh ThunderPowers are just over 6" with the wires and there is over 1/4" of room left at the front of the compartment. Depending on the pack width and thickness, packs from 6.25" up to perhaps 6.4" long may fit. My 4S/3300mAh TPs fit cross-wise in front of the motor, good if I ever need to move the CG forward.

                    So far the K-45 seems the best prop when running by myself. In race water that may not be true, I'll find out Saturday. Note I am just trying plastic props - the local club wants to keep prop tweeking to a minimum to keep things more equal. Suits me.

                      Unfortunately I have to wait until my lake conditions improve a bit before her maiden.

                        UL-1: Inner Dimensions for Batteries

                        UL-1: Dimensions for Batteries

                        Well guys, I've been listening to all the talk over this hydro. I ended up buying a Red UL-1 over the weekend from Steve. The first thing I checked was the inner dimensions for batteries.

                        170mm (L) front to motor mount
                        28mm (H) @ front
                        45mm (H) @ motor

                        Plenty of space for any pair of 2S LiPos ever made! I'll have to wait until April to test it. In the mean time, I'll be tuning in for any mods from the one's living in warmer climates...

                            Absolutes are dangerous. These Hobby City 2S 4900 mAh won't fit because they are 175mm long.
