how coe the motor is not inside the hull.. is the motor waterproof? secondly the suggested motor any good? S2858-2630 Brushless Inrunner (2630kv) what speed i can get with this motor on 4s, and can stock motor and ESC handle 4s?

Glad that I re-routed the watercooling outlet via the top of the motor casing (as advised by the HK video & others) to visually check for an adequate cold water flow . . since, during my initial bathroom tests the water flow was shown to be quite poor . . this is apparently due to the hole in the plastic water intake scoop being too small (this is quite obvious if you look closely) . . accordingly, I cut-away the plastic intake scoop and fitted a larger 3mm internal dia metal tube (which more than doubles the cross-sectional area) and this resulted in a really good outflow from the discharge tube . . I have always used 3s batteries and subsequently had no burn-out problems with either the stock ESC or motor . . I wonder if the owners moaning about burnt-out stock ESC's and motors bothered to check if their watercooling output was adequate? . . my only real problem is slowing down enough for the turns (Lol) . . seems more of a driving challange than my monohulls !

Got another run in tonight with this boat.. I like it very much! I have put the outboard of the F3 tunnel boat on it by the way.. That unit is a lot better..

I bought one recently, no user manual for the ESC. Those who know the model pls let share here. Where can I find the manual? Pls help, dear!

My boat's flexible shaft breakage. Can't purchase. But how can be damaged once operates in? Reconstruction is needed...How do I convert it?

Spare bearings are available from Carolina-discount, look them up on eBay. They also sell an upgraded flexi drive for this Beilli Outboard (and Kyosho Dolphin)) that uses a bushing in place of the bearings. The replacement shaft is a really great upgrade, mine has over 4 hours run time on it and still no slop in the bushing. You have to keep it well lubricated though! Regards, Clive.

Great boat , hull thin,light ,strong.The outboard made from plastic with flex drive and 4mm shaft and 2 bearing .The esc heat too fast cause it draw to much amp. The prop is might be too big. If not reduced the prop size or just go with a turnigy 120a esc , it could run on 11.1-14.8v ,with out worry.It handle very good but the servo is kind of weak and noisy.Servo need more torque if you wanted to mod it.I had put Ammo brushless motor on stock outboard with 120a turnigy esc,lipo 14.8v and octura x640. It's flying and needs more weight in the front and adjusted the AOA

Hi! I'm The3PK. Just received hornet today it more valuable comparing to the price. Outboard is brushless size 380L, it's not 540 size but fast enough when used 3 cell lipo. The weakest point is water proof of esc isnot 100 sealed. I change prop to octura 3 blade 3/437 (Diameter 37 mm. Pitch 1.4) speed improved fascinating. The next run I try to setting outboard angle and lift it up a little bit for more stable while running in the water. Thank you the hobbyking to bring this stuff in your store and hope you are spare part to supply soon.
