Turbochopper 30

[CornelP]

Well guys, I thought I'd share with you my latest mono: Turbochopper 30.
The source is purely Chinese, a small company making just this boat, originally for IC motors.

It came quite ok, nice finish, thick gelcoat (found out after a nose crash). The FG is just stranded mat, quite ugly, but it got the kevlar treatment and is now stiffer and looks slightly better.
Power is now a Leopard 4074 on 4S 5200 30C, Turnigy 180 ESC and an X442. This setup gave me just enough juice for a 6min race (that I won :banana: ), actually 6min 30seconds. I also tested it with 2 x 2S 5400 20C Etti and I got about 7minutes out of it.
Stinger, motor support and motor jacket are all home made, rudder is a HOTR cat type, with a water pickup that actually works!

I also installed a floodchamber, about 2.3 liters, which will now turn the boat in about 5 seconds (courtesy also of 120g of lead).

I'm intrigued, where are you? You mention recent nationals which makes me think of the America but also mention 6 minute race which makes me think of anywhere else, could it be that you are trialing mono2 in the states, I know NAMBA is a Naviga affiliated club so it sounds reasonable, though I would have though mono1 would be a better bet coming in significantly cheaper than N1 mono or even Pspec mono.

Iony is right, we just managed to push a demo race at the FSR Nationals this weekend, hoping we can get it official for next season. First step will be Mono 1 and 2, followed by Hydro 1 and 2. Most of the officials in the federation are... over a certain age and reluctant to changes, but there are plenty of Mono races in Europe, so there is nothing they can argue. This is why I prepared these two boats: Turbochopper for the Mono2 (actually more like Mono 3, but that was removed by Naviga) and the H&M Intruder for the Hydro 2... both on 4S, standard Lipos with weight under 140g/cell, etc...

Wow that was absolute chaos but a lot of fun I bet, I wish you all the best getting some FE racing sorted in romania, I'm sure it will become a little more sane in no time with a bit of practice, we had a fair few mono3 racers here in the UK and when naviga killed mono3 we stuck our fingers up and created supermono a national class for 8s baby, great fun!

I love the look of the intruder, that's one beautifull boat.

do you like this turbochoper hull/ they are cheap and i am looking for a boat to run our "40" class. we are making boats that can not exceed 40mph, each boat will have a gps and be checked at the end of the race. i have several big fast boats but i was thinking a 30" would be good because i wouldnt have to deal with the rough water flips.

[CornelP]

The hull is the most stable I have. It really takes a lot take it out of the track... on a normal oval, full throttle is not a problem. As it is now, with an X442, I got 75kph avrage with max of 82kph (46 to 52mph). I guess that with a smaller motor or an X440 you can get to what you need.
