I copied this over from R/C Groups. For anyone that's interested.

As you know HK (as well as some other vendors) released a few new boats from TFL.
I'd never set up a stepped hull before & I liked the look of this one as soon as it was posted up on their site.

Well, I needed another boat like a fish needs a bicycle. But I bought one anyway.
It arrived Thursday & I ran it yesterday. I thought I'd share my thoughts on it.

Firstly, I'd like to say that I think it's possibly the best ARR hull I've seen. Beautifully finished, solid glass work and well set up inside.
The steps obviously strengthen the bottom of the hull.

The finish is first class with the clear coat over the graphics & decals.

Unfortunately the battery tray had broken loose in transit which shows that they still use that hot glue type stuff without prepping the inside of the hull before they stick things in. The waxy film is still on the resin. So before the motor mount has a chance to break loose I scuffed the surface beside the mounts & tray, wiped it with some Acetone & epoxied in some 1/4 carbon rod.

A nice feature is the adjustable T bar mount at the end of the stuffing tube. I played with that & the motor mount adjustments to produce the most freely spinning drive shaft, and guess what. I ended up at the same points as they started. Shows they are paying attention to the set up.

It has a good solid true running coupler. A big plus. Still a two part square drive though. But I don't mind that any more.

The transom has a piece of ply added & then a layer of glass has been laid over that to seal. Another plus.

The motor is one of the TFL black motors as sold by HOR Racing as the 'SSS series. I've got a couple of those motors & they are efficient powerhouses.
On this motor (3660 2075kv) I even worked up to an m445 prop & the motor was still coming in just tepid, with long run time. Stock prop is a TFL 440. Nice finish
& almost balanced. All I really did was sharpen it a little bit. Drove the boat pretty well.
But as usual with this sort of KV & this size boat, the old 440/3 performed the best

The Stinger is of good quality with nice tight fitting bushes with a 3/16 shaft to suit all your 3/16 props. The prop cone nut is held on with a set screw to a flat spot on the shaft. I have that system on a couple of boats & don't mind that.

So this one will be easy to change the flex to a welded stub flex drive. Just pull out the teflon liner & its ready.
Possibly aimed more at the European & Chinese/Asian racers, where they can race stepped hulls, but a great sport boat for me.

The Smash Shark is a no step hull & is set up pretty much the same way, & if it is built like this one, will be a good option.

As usual, Check the tightness of all the mounting bolts,
strengthen the motor mount & battery tray to hull join, mount your gear & go.

I honestly think that TFL have been listening to the suggestions & comments about their boats. These are a far cry from the offerings a few years ago.

The V is very flat & as such turning at full speed is a bit tricky. Wide turns are ok bit tight turns sets up a lot of skipping & spin outs.
Perhaps our European friends can offer some set up advice from their racing experience. Please.

I've got a few motors to try out in this thing, but the one that comes with it is certainly a good one.

Here's some pics & a bit of a video.
