Okay, this is my first post in this forum, and I'm hoping for some advice on what to do with issues regarding my new ProBoat Forumla FASTech.....
1. Yesterday, I purchased this boat, brand new in box, from Hobbytown USA in Tukwila, WA.
2. The store guys advised me that the current Venom battery packs I use for my Traxxas cars would work in this boat. These are 8.4, 4200mah batteries.
3. Yesterday, I tried running it on a local lake, but the batteries appeared not charged adequately, as when I tried pulling the throttle, the boat would jerk really bad and shut off. I decided to charge the batteries all night and give it a test.
4. So here's what I'm getting............. intermittently, if I start from neutral and pull the thing full-throttle, I often get a start / stop... in other words, the motor turns, but only for about a half second and then stops.
IF I PULL ON THE THROTTLE SLOWLY AND ACCELERATE, I can get up to full throttle when running dry - OUT OF THE WATER.
I found this awkward, because I thought it had a feature that told it to stop if it was not IN the water ?????
5. So today, just moments ago in fact, with both batteries fully charged, I take it to the local lake again and pull off with a slow acceleration; everything seems to be working well, but when I try to open 'er up, try to go full throttle, the same thing happens - it shuts off. I could get it to about 3/4 throttle, but after that, it would just shut off. Sometimes, I could hammer down full throttle and get it to "vroooom," but then shut right down.
After about 15-20 minutes of messing with the thing, the batteries started going down so I brought it to shore. I notice the starting and stopping gets worse as the batteries appear to discharge, but I get no indicator on my controller.
Which I ask... are the battery strength lights on the controller for the transmitter battery strength or the batteries in the boat ???
So - my dilemna is = what do I do? Anyone experienced this issue before?
If so, what recommendations do you have to fix it where I can run wide-open?
Is it an over-voltage issue? Are these 8.4 NiMH batteries too much voltage?
Please help !!! I live a long way away from the Hobbytown I purchased it from, so I need to know if I should just take it back and call this boat a POS, or do you guys have any ideas on how to help me ???
