Delta Force Vortex Hydro 34 projeck gone wrong

[ErickTheBold]

Hello group,

4082 motor around 1600 kv, run 6s, change the solid shaft for a flex shaft and adjustable strut, prop 45mm.

Sorry, I'm an aging paraplegic that forgets from tim to time..

Although it looks better than some of my early builds there are numerous things to bring to attention.

1. solid shafts are more for scale boats not so much for the Ferrari you put it in. flex shafts are the rule these days because they are adjustable.

2. KV is high for a single in that hull, dual motors as you said you have them could get by on 2- 3S per motor. I'm not familiar on dual motor sport hydros. I've done a dual cat, not much different except the turn fin. YOu didn't show yours so maybe you don't have one that's o.k. for now, no worris...

3. I'm curious what is under whatever you used to insulate your connector joints??

You can get this to go fast with what you have mostly but I suggest new drive lines with flex cables and adjustable struts.

If you wanted to do a single drive, I suggest a larger motor with lower KV about half of 3900KV and run on 4s- 6s.
