Wibble wobble

Hi there,
just bought a new recoil 26 and was wondering what upgrades I can do to get it faster without changing the esc or motor and was wondering what 3s battery is best to get?
Thanks

More speed isn't just a matter of adding power. The hull also has to be stable enough to handle more speed, otherwise you start flipping over a lot more. That thin ABS plastic is going to flex when you push it, so this really isn't a boat you can push super hard. If you are looking for 30-40 mph speeds, it just isn't going to work with this hull.
How fast is the boat already? How much have you run it yet at your local lake to get a feel for its running characteristics? The things you can do that aren't expensive and won't make the boat temperamental to run are tuning the prop height and angle to get just the right attitude in the water, filling the back corner of the hull and sanding it to a sharp cover to reduce drag and the hull's tendency to the stick to the water which improves handling, and switching to a metal prop that has been sharpened and balanced, maybe reworked a bit with some cupping. The hull tweaks will make the boat run smoother and be more predictable, which lets you push the speed a little more. The new prop can actually give you some extra speed, quite a bit if you learn how to work props and take the time to experiment. But before doing any of that you really need to get 20-30 runs in at your lake to see what the boat actually needs. You might find that it's lots of fun as it is and decide to go with a higher end fiberglass hull later on that you really can push hard.

Hi thanks for the info I just want to get it faster than it is and then see where I go from there as I will probably end up getting a higher end one. Was just wondering is there any prop you would recommend?

It probably came with a plastic prop. If you get a metal one and sharpen and balance it you can improve the performance considerably. A word of caution though- the modifiable metal props are beryllium copper, and the dust from filing them will do major damage to your lungs. Read up on prop sharpening and modding to learn how to do it safely if you decide to go down that path. There are guys who will do it for you too, for a price. After sharpening and balancing, there is also going with a larger diameter and cutting off part of the prop tongue, cupping, and a few other mods. Prop work can add 20% to the speed of a boat over what the cheap plastic props can give you. But it's also time consuming and can get expensive when you start experimenting and ruin a few.

For a good start, measure the diameter of the prop you have now and get an Octura metal prop that's around 5-7% bigger. Cutting about half the tongue off will bring the amp draw back down and increase the speed, and a quality sharpening job will cut the amp draw back down close to where it was with the stock prop. You also could just go with a larger plastic prop and keep a close eye on your amp draw to make sure not to burn anything up. You'll never get the performance per power used that way, but you can improve things a little without much effort or expense.
