Ok, a controlled formula then - restricted motor etc.?

Restricted motor and ESC... supposedly... Clubs run their own versions.
NAMBA stated Nixx batteries and a 700 brushed motor only and a minimum of 24" long and real hydro resemblance.

SWAMBC, the club I race with here in the UK, had a similar class which we updated for this year to a restricted brushless (Mega 22/30/2), 4S 5000 lipos and 2Kg weight limit - everything else is open.
We ditched the Speed 700 BB, as 5 minute heat racing meant you got maybe 2 meetings from a motor before it burned up. 3-4 motors for a season's racing was getting a bit expensive, compared to brushless.

We were working on "ditching" the 700s as well, but don't have anything official in place yet, so what our clubs around the country are doing is making up their own sets of spec rules... all seem to be basically based on the SV27, BJ26, or UL1 motor packages and 4S1P Power systems... Hull just has to be fit the existing LSH rules and be 24" or longer.
Maybe something more official will be in place by next season... Things move a little slowly in that department in NAMBA...

I was very keen to get a minimum hull length as part of the updated rules for 2009, but instead we settled on a minimum weight limit. There's always someone who's convinced a tiny boat with monster power will be unbeatable. Uncontrollable? Yes. Not unbeatable
We chose the Mega as these are relatively cheap in the UK, but are well made and should last a long time.

The reason most are picking one of the RTR motor offerings is just for that reason... We wanted a place where people could race their RTR boats off the shelf and be somewhat competitive... We'll see how that works out this season, as many out there have UL1s, and a few of us have Elams...

The Speed 700 BB in the UK has given us some of the best and closest racing for something like 14 years or so. High capacity cells (and, I suspect, a lowering of quality standards) have basically killed the 700BB as a viable FE racing motor, especially for 5 minute racing - it just gets way too hot, then burns up. The 22/30/2, in contrast, is barely warm - not surprising, given the difference in efficiency between the two motors.
We're expecting the new restricted class in 2009 (we call it Formula 4) to be a lot of fun, especially as the boats are faster, even with an extra 2 minutes run time (7 minutes required). Not sure my nerves are capable of dealing with 7 minute heats
It's an official NAMBA class which limits both motor and cells, as well as the standard hull size limits. You can download the rules from the NAMBA website.
I think Darin's club has a little more liberal rules than the national set.

Not really... we follow NAMBA LSH rules, except for the motor and cells... It's not just our club... I don't know of any clubs still running LSH as a 700 class...

I didn't make it to the race because as I was driving up there, my 2003 Tahoe died on I405... Had to have it towed home...
Symptoms pointed to either a fuel filter, fuel pump, or TPS, so I replaced the fuel filter, which I found upon inspection was very obviously clogged, and it's been fine since then, so hopefully that's all it was.. didn't have time to drive up there after I got it fixed or I would have...
Guess the testing will have to wait for another day... bummer, but it is what it is...
