H m viper setup

[U.L. HYDRO DRIVER ICE]

I have a H M viper and would like suggestions on a very fast setup and reliable . Batteries / motor / prop/ etc I would like to be around 60mph thanks for looking
Thought about trying a 6xl

[10gauge]

The H&M Viper is a great performing streamlined hydro. The setup can get finicky after 50mph, take your time and experiment with COG, strut height/angle, rudder angle, and turn fin size/angle. Mount the strut 3/16" right of center line. Before purchasing LiPos, measure the height first to determine which size LiPo will fit along the sides of the motor. Use at minimum, 3300mAh/25-30C LiPo packs, capable of delivering at least 160amps to give yourself a safe margin.

To get into the 60mph+ range, I would recommend the following combination:

Neu 1515/1Y (2200kv), 4S2P/6600/25C+, CC Hydra 240, m645

The 1515/1Y is a monster motor for this hull, but very versatile rpm range which you could also use for any boat between 27-30in. Others may recommend a 1512/2D or 1512/2.5D, but they are less efficient than a 1515. Furthermore, the weight of the 1515 is comparable to an XL motor.

I own the sister of that hull the "Viper II". It'll be an achievement if you get that hull to run stable at those speeds it is only 24" long and it has a lot of tunnel to compress air under.
you may need an air dam as well as the rest of the suggestions above and still, it'll be a feat.
BTW Charles, it's been rainy here, no fiberglass work has been done yet.

I agrees with the speed statement. I would think a bj motor and speedo combo would be great on 4S with a m545 prop. I am thinking 45mph for a on the edge ride around the track.

How about a hacker 8L 3000kv would this work on 4s and a good prop suggestion . It does not have to be in the 60mph just .

I have used that exact setup on mine and the thing hauls... I have to say I used it in a Dark Horse Shovel with better success, I GPS'd it at 62mph.
It had a 440 or a 442 prop on it. It's just for a couple of passes though, there is a lotta heat produced, too much for oval racing.

What about if I used a x438 and etti 150 esc or would you suggest another esc and what kind of batteries

[Ub Hauled]

You wanna use the highest C rating you can get your hands on, that being said,
I'd suggest 30C or higher... if you cannot afford it then get 25C.
A 4500+ capacity is a good start

Etti 150 is plenty

2 2s lipo packs correct on this setup

sure, make sure they are in series so you get 14.8v
