I’m having trouble getting a 4s setup to work in my DF Vortex 34 Hydro. When I built the boat last year, I set it up to run on 8S. It has ran great in that configuration. I used 4, 2S@5000mH packs hooked in series, powering a SW Pro+ 150A HV ESC with a cap Bank installed. I ran a Leopard 4074 1050kv motor turning a M445. It ran in the low 60’s. The data logger showed it running about 75-85A max.
So I wanted to try a P Sport setup, to contemplate the possibility of hitting a race or two. I installed a TP 4050 2310kv motor and put a smaller prop on it for test, an ABC 17-14-17. I reconfigured the batts for 4S-2P for 10,000mH. I upped the ESC to a SW Pro (no data logger, didn’t think I’d need it) 200A 2-8S. This thing is going into overheat protection running the first straight and going thru the first corner. I got it quickly to the shore, and the ESC, Motor, Caps, Motor connectors and batts are all very warm, about 130-135 degrees. The ESC was too hot to keep the fingers on it. I checked the water system and it’s fine. The boat has had a dual cooling system on it from day 1. The book says this motor is a 5D. I have the ESC set to 0 degrees of timing, 4S and LVC was 2.5V, just to take it out of the equation. It is a thermal limit cutoff, because I tried to run it again, and I had to wait for the ESC to cool down out on the water before it would give me another burst. Almost had to send the rescue boat out after it..
Does anybody see something I’m missing? Note: Boat is heavy, about 11-1/2lbs ready to run. But it pops right up on plane, always has...
