    Race classes by motor weight is probably the least fair way you could possibly run a class, if one person can afford a 90% efficient motor and another can only afford 80% then the guy with deep pockets has double the output power available to him before overheating his motor than the other guy, if you have a set run time with a set battery energy the guy with deep pockets only has about 12% more output power, which is what we see here, guys with feiagos and zippys can compete against guys with lehners and thunderpowers and actually have a chance of winning as good setup and driving can easily make up for 12% more power which should yield a boat 4% faster down the straight, doubt even the best drivers can make up for 100% more power which should yield a 25% faster boat.

      Kyle, thanks for sharing your build. What prop were you using?

      Paul, I was just talking to one of the local guys about the approach you'll are using to level the playing field. I really like the thought process.

        Spec races that require the use of only a handful of preselected motors is for sure the best way to level the field with the same done for the batteries. I was refering to all the other races, when any motor brand is used in a given size hull. Pardon me for getting off subject.

          HydroNigel is definitely the man to beat in Mini Hydro, he always builds light and VERY fast boats, last time we raced was at the 08 nats, he won, I came second but that doesn't tell the whole story, he was on another level to the rest of the field, 4 laps up on me after our best two 5 minute heats.

          I haven't seen that particular boat run, but I wonder if he gets the runtime on that setup or runs his laps then pulls in till the end, the Het 2w 4800 is a clone of the mega 16/15/2 that I use and on 3s 1500 LiPos should be spinning a few K higher, about 50,000rpm.

                Here's a boat video of a micro rigger out of France. Enjoy.

                And another video after tuning.

                    How small do you want to go as far as micro and how heavy is the starship?

                      305MIAMI,

                      There are several available throughout the world. Amp_User's question is very appropriate.

                      In addition to his question:
                      What size are you looking for, what do you want to do with it (oval, small pond, swimming pool, etc) and what speed do you want to go?

                        micro boats

                        Hi Guys, heres a pic of a couple of my little guys. The one in front is a wood hydromite I built from plans I got free and scaled down 14 inches. It has a mystery brand 3000kv outrunner and 25 amp spd con. I run a rhino 40c 3s 1050Mah lipo. The prop is a 432 cut down to 430, detounged and very thin and sharp. Its crazy fast. Very fun to run. The cat is a carbon fiber micro scat cat from BBY. Its now an empty hull, I am still looking for the right set up for it. Mike M

                          Mike, those are some good looking micros, nice builds. What setups have you tried in the micro scat cat? I've been looking at picking one up for quite some time and have crunched numbers and setups. Send me a PM and I'll share with you my thoughts on setup.

                          Can you confirm where you got that turn fin for the hydromite?

                                I tried the website that the guy said sells that beautiful little hydro but it's only a forum. No store. No products. Bummer. I would love to have that hull about 32" long!
