***NEW*** - Pro Boat River Jet Boat - 23"

[DBJr]

I was chatting with Rafael over on RC Groups and he said you can use a suitable 3650 or 3660 size inrunner motor in the 2200kv-2600kv range and it will bolt onto the stock motor mount without modifications. I didn't think it was possible but since he designed this boat and knows it better than anybody, I believe him.

I was looking on OSE and Steve has a nice Leopard X2 3660 2380kv motor that looks like it would work just fine. Of course I plan to use the replacement stock motor that Horizon is sending me first but if that decides to throw magnets, then I'll try this.

Rafael, thank you so much for your support as well.

Good to know! I glued around all my magnets and so far 4 packs through it today with no more issues. Here is a self-righting test that I have had a few people asking me about if anyone is interested in knowing how it self rights on 4s vs 3s.

For those of you with motors that had magnets come loose inside and are getting new motors from Horizon, can you please message me so I can send you call tags to get them back? we need to look in to this further.

Thanks.

Thinking about getting one. What I'm wondering is why the low Mah on the batteries? Why not a 4-5000 mah to increase run time ?

5000mah Battery is too heavy for the boat. It already leans heavily to one side with a 4000mah 4s in it. 4,000mah does work fine though.

I thought about using a 4S 4000mAh pack but was concerned about the weight so I decided to go with a 4S 3300mAh pack. It still leans to the battery side a bit but not too bad.

What would be the largest mah and c rating on a 3 cell would you all rocommend ?

I use 3s 3800mah Gens Ace 45c and it works well. My 4s pack is a 2200mah (for quick speed runs) or a 4000mah both are 30c. I think 4s is a bit too much IMHO, because I find myself turning the throttle rate down because it is very quick and nimble and causes it to be uncontrollable at times. The higher the c rating the better, but you don't need a 90c pack by no means) and don't put anything in it under a quality 30c pack for sure.

Yea, good move on your part. I run the 4s 2200mah more than the 4s 4,000... but both do work depending on where I'm running it 3300mah should be the optimum range of size and weight.

Has anyone experimented with using a 2S pack in the stock location and another 2S on the right side somewhere? I'd guess that would balance the boat better.

Unfortunately there is no room for another pack because you have the ESC and receiver on the other side. Not to mention the slot for the optional trim servo would get in the way and the ESC is not wired for 2 packs in series.

It happened 😀

that would pretty much kill the self righting ability, seeing how there are reported difficulties doing so on 3S

Yeah, I included moving the ESC and Rx as well as mounting a battery try under the admittedly unspecific "experimented with." Rewiring the ESC to accept packs in series is trivial.

If you are running in open water the chances of flipping are less than any other boat because there is no protruding equipment to grab and force the boat over. I don't run self right in mine. I run a inrunner with s straight coupling and have yet to flip it **knock on wood. Its a much more predictable and better performing boat with no steering bias.

Now, If I were to go run in rough water, I wouldn't run without it. I'd have to be in rough water and have to watch my boat float away on its lid.
