I ran up to 47x1.4 on previous setup 2000kv/4082/6s... From my understanding a brushless motor will try to pull whatever you throw at it (till i breaks, shortens out, overheats, etc). Could be wrong about that, but the best way is to test it, and you did...

@@daiciuapostol79 ok, now i get it. I think it isn't like you have a bad running or slow boat by any means, but you could consider to try something like a ride pad. Think its do-able and repairable if it doesn't work. Or maybe build a bit larger hull...? Dont know how big it is, but personally think most mono's are quite wide, for speed i would guess a bit longer (and low profile) would make it faster...

My experience so far is low rake (like x647) run more stable than hi-rake (like abc). So i run preferably x style, if i want fastest speeds i run hi-rake. Also noticed with hi-rake i need to be more subtle with accelerating so i don't "upset" the hull...
@daiciuapostol79 29 күн бұрын
@@peteroosterhoff8850 thanks Peter I think that because of the position of the batteries I can't find the optimal setting because my boat is very stable with ABC propellers, all my records were made with ABC and a Titanium propeller also high rake as I think you know this, so I think that due to the fact that I use 3+2+2s for 7s and the position of the two 2s is not in the center of the boat but somehow on the side, the boat becomes unstable above 115 kmh
@peteroosterhoff8850 29 күн бұрын
@@daiciuapostol79 Just thinking i remembered what i noticed (before i worked the hull!) was that the hi-rake first with 2000kv was just fine in its handling, with 2310kv boat almost was un controleabel (shime walk) Don't know the effect was from hull or prop. Weight off centre personally don't think it affects its extremely unless its a lot off course or high up in the hull... Btw i had laying around a motor which i thought was old 1800kv (also needed to replace bearings so also could be something wrong with it), but gave same speeds, so ordered the newer version. It was on backorder so i most likely won't be doing a all out 8s run this year...

after some time I brought the old Leopard engine back to life, a few passes on water full of algae after a hot summer, on 4s it was stable and a predictable speed for the rusty old motor, on 6s after a strange power cut on the first pass, (the first one with ztw)maybe the engine woke up suddenly and asked for power, but the two 3s packs already have a swollen cell each and couldn't keep up with the engine's demand, the jumps are due to the piloting she don't like tight turns at speed

Ive read reducing diameter (blade tips) makes them better (buy 1 size bigger than you need). Can't tell its true. But did it with my 3 blade, but also changed bottom hull...

for me it's hard to tell the difference just from the sound of the engine, yes a propeller for hydro I think than for a vhull, it cavitates a lot when starting but when it gets up everything is ok except for the jumps that were due to the small waves created from the previous passage it seems that with this propeller it is very sensitive to these waves, but it seems promising at least on 4s with 6s to much lift maybe different setup on stinger
