Last Run of the Season
Had some beautiful fall weather at the lake yesterday, and a rare opportunity to run the boats on very calm water.
This was the last run of the season and I got in two back to back runs on the 5S parallel setup running the T180 and CC1515 2200kv motor and P215 prop. I think I can say, with reasonable confidence, that this is a solid setup, and the Eagle Tree data I have collected to date supports this.
I placed the batteries a bit further ahead on both these runs to help stabilize the boat (just a bit rearward of the center position). the boat ran very stable with only a bit of chine walk if I crossed my wake or other disturbance in the water. Unfortunately running wetter on the hull sacrificed some speed and I only maxed at 70 kph (approx 43.5 mph).
ESC and motor temps were nice and cool @ 20 *C (68 F) for ESC and 15 *C (59 F) for the motor. The batteries were hotter at 40 *C (104 F). I also noticed the wires between the ESC and Motor were running pretty warm at about 46 *C (115 F).
No flips or ditching for two good solid runs but the hull had separated again where I had repaired it. The boat stayed dry inside despite the separation.
I ran both batteries on the Eagle Tree without clearing the buffer between runs, I only got about 8 minutes to LVC on the first set of batteries, and then a wire broke off the Eagle Tree about 3-4 minutes into the second run. The Eagle Tree graph below shows approx. 11 minutes run time from both batteries.
I had the LVC set at 3.2v but I'm going to bump it up 3.4V for this setup. My batteries were pulled down a bit more than I want to see with only 12-15% residual capacity remaining. This is going to further shorten run times, which is a bit disappointing with the parallel setup, but this setup is power hungry.
Will have to try running the 1500kv setup on 5S parallel next season to see what the run times are like.
This will be the last run of the season for us. I brought all our boats home with me to "winterize" them for storage and do up any minor repairs required.
