ML BOATWORKS GSX 380 Q-Sport Build

[T.S.Davis]

Why spend 3 times the money on a Neu, when they seem to fail all the time lately, and the GSX380 balances out perfect with the 5692 Leopard.

Mike, I'm not discounting what your saying but................. because they win. haha

I've seen, driven, or raced against all the boats that set the last 4 NAMBA heat records. All running 1527.

Zola tried an experimental TP in his ML but the KV was too high. The boat is ridiculous fast but everything comes in too hot. He's killed the boat too. His build can't run that fast. Too many flight of the butterfly incidents if you know what I mean.

I still think it can be done cheaper too but I don't think the 56mm motor is necessary. That's all.

Why so much prop on the 1.5d? We never ran that much prop on that motor.

I don't like the D winds in much of anything. Amp hogs.

Just wondering, why not a 1530? More tq than a 1527.....just asking....

[nichismo]

ah 5692 rather, my mistake.

What do you guys think of maybe running one of these? :

We tried that too. Not sure why it doesn't work as well. The 1090 I mentioned would be a dog on a 455 but not on a 3 blade 455.

Guys were running the 5692s at nationalsthis year.. All i can say is fast.. My q mono buildis being built around this motor..

If one is afraid to run one of those unreliable Neu 1527/1Ys he could save a little $$$ with an HET 700-98-1170. Better quality than a TP or Leopard - at less cost than a Neu with similar performance. It needs a slightly higher pitch prop than the Neu but can deliver the goods.

Can you suggest a specific prop for the HET?

Good discussion guys.....really appreciate the insight. So far the only NEU motor I have been able to have experience with is the 1527 1.5Y in my 1/8 scale. Still have some tweaking to do....but I guess I'll see how long it lasts. But right now it has me concerned on how hot it gets after a 6 lap turn. However as Terry and Todd can attest to it is quite a bit heavier boat too. Its very stable but I don't think I'm getting quite the speed I need to be fairly competitive....not after seeing the 1/8 scale runs of Terry's and Todd's boats. Of course Terry's was so fast it seemed hard to keep it on the water....LOL So I may be thinking of an alternative for the spring unless we can figure out something else.

As far as this Q-sport boat I'll be researching the other motor options that you folks are talking about. Would like to experiment with a couple of different motors and see how they perform. At the same time trying to keep the price reasonable....trying to keep it well below what I have into my 1/8 scale...LOL $$$$
I think I am starting to go back to some of my aircraft thinking which is I would rather look at motor out put vs weight package instead of trading off motor weight and then having to add weight to accomplish a good COG. (It seems like such a waste now that I have 16 oz of extra lead I need to be pushing around in that 1/8 scale)
It seems more and more to me that it is extremely important for race setup to hit that happy medium for speed and satiability. Hitting that perfect weight to power ratio is critical. [Just my 2 cents]

I know that was the only thing I figure out when looking at Mikes power package....I was like why the heck would you want to go to a 56mm motor that was 10oz heavier with all that power when 40mm motor would do just fine. Well I went back to my aircraft building...weight vs matching power package. If I'm going to have to add weight why not have it in my power package. Not saying that the Leopard is the best choice, but its a start.

Thanks again guys....learning a lot here through the discussion....

Just had a read through all this Mike. Good stuff here.
I'll be putting a 56 series motor in my next 1/8th scale hydro for sure because it is the 'Such Crust II' which scales out to 51"
Cheers.

As Jay mentioned the HET motor perform I am running onion my Q ML sport and am having fun.

I had the Neu 1527 1500kv in my GP400 and switched to a TP4070 1770kv with the same prop (ABC 56mm 1.6 don't have the # right now) the TP was about 7mph faster and ran 30deg. cooler. I'd say that pretty much speaks for it's self. BTW the TP 4070 is closer to the size of the Neu 1530.

I'm starting to be a tp fan myself but that not really a fair comparison (unless you factor in $$) the 4070 is bigger and more kv so I'd expect more speed. Now compare the same kv and closer size motor....which I plan on doing soon...

It really stuns me at how much positive feedback overall im seeing in regards to the TP power motors, almost seems too good to be true, considering how often i see Leopard motors being used.

But im going to purchase this kit too and was curious if anyone could maybe shed some light on how they think the MHZ version of the watercooled Scorpion 4035? Sincw its 1260kv it seemed like maybe a decent choice for this boat?

Look bud, I've personally tried to, castle, neu, lehner, dynamite, associated, sss- to name a few and I can tell you for the money they can't be beat.
