      Good looking motor, but twice as big as the one on my Dragon Hobby boat. How does it run? How big of a boat do you have it on? I would imagine you boat would be at least 36" long. My boat is about 23".
      Does it run well?IMG_3531.JPG

              Thanks Mark,
              I will have to look into those. I bought 5 Dragon Hobby boats last year and an extra motor. I'm going to run 3 of them this summer and try a bigger diameter flex shaft. I do like the idea of bevel gears rather than a flew shaft. But at the same time I like the look of the Dragon Hobby "DAC" F1 boat. The Baba looks good too but no clear windshield and driver half figure. All fun stuff. By the time I get done I should just go buy a real "older used" Seebold hull and V6 Merc hop in and go play on the river during the week. But my wife would kill me. This was me in 1974.

                if your running the flex shafts thats your decision i up grade my motor witch was part of my problem but for me it wasnt fast enough to much torc was part if breakage so if you stay with flex then make sure you pull shaft a grease the shaft it self will help you from braking them dont run a bigger motor they will brake i even went to drumal hand piece used the flex shaft out if it witch worked better but still broke good luck with them its a neat looking out board

                    I tried a hobby king outboard on my first 30 inch scratch build because I thought it would be easier and cheaper than a regular setup. I was totally disappointed and really would not recommend it to anybody. Poor performance, shaft broke repeatedly, engine seized. Harder to upgrade than a standard set up. I replaced the broken parts , sold it cheap and fitted a standard motor/shaft/rudder setup. Now I am experimenting with a jet drive unit. Can anybody suggest a suitable engine for a 26mm jet? I started with a 2845 2750kv on 3s as that is what was running my standard drive shaft with 40mm propeller , but the jet is quite a bit slower than the propeller. Not sure how many revs I should aim for with a jet unit.

                      Niel.
                      A 26mm pump is a bit small for a 30" boat.
                      Lots of info on jet drives over here.

                        I wonder how the TFL motor on a Hobby King Hornet F1 boat would work? I bought a Hornet then sold it because it was too big for the CNC Aluminum Merc outboard. Hum mmF1 Hornet rc Boat.jpgWyatt going in h2o.jpg2019-02-18 07.28.22.jpg….

                          Be careful how much $ you put into that HK Hornet, it has inherent issues you cant over come easily, many have found you can improve turning by adding wedges near the sponson tips, the hull wants to dig in a turn too much and hops or spins out easily.
                          search HK Hornet mods over at RC groups there were a few threads I went thru to make it run better.... gave it to the kids

                            Never ran it because it was too big. Sold it already for what I paid. I like the way the Dragon Hobby boats run, much like the real thing. If I can only find a cure for the flex shaft problem. I bought some 0.130" diameter flex cable will try that. The Dragon Hobby boats, DAC and Baba handle differently too. DAC seems better in rough water and is generally more stable. But both are cool. I have Blown them over, barrel rolled, stuffed them much like I have seen at full scale F1 races in Bay City, MI, St' Louis, MO, Pittsburg, PA and Algonac, MI. Sadly my friend Wyatt Nelson is paralyzed from a bad blow over in Kentucky several years ago.

                                I know what you mean. That's why I replaced the Teflon tube with brass and put a larger grease hole in. Also I tear them down after a run, three max, ang grease the whole shaft at re-assembly. I wish some one made a boat as scale looking as Dragon Hobby. None of the other look as good.
