Question about classes?

[Fastfish]

Guys I'm new to the RC Offshore boat world but not new to the RC world. I purchased the 41" Genesis and in the building process. I've aslo bought a 41" Fightercat Cat Hull for a future build. My question is...where can I find out the different classes of racing these things. I believe length has something to do with it.

This is for mono's I believe............may be for all of them

[T.S.Davis]

Cats run offshore or hydro and those tables apply to them too.

Both of the OP's boats can race in Q and T Offshore in NAMBA (S class is moribund, SAW only). Like Terry implied, the cats can also run in Q and T Hydro. I have actually won two regional races running my SprintCat in Q Hydro when the water was rough enough.

Here's the official NAMBA rule book. Covers Gassers, Nitro & in section 28, FE. http://www.namba.com/content/library...a_rulebook.pdf JIM

Thanks Guy's! I have (2) 41" cats. One a single motor and the other will be a twin build.

Pay particular attention to the rule regarding twin motors and power. There are two (legal) ways to configure a twin:

1) Each motor gets 10S1P w/max 6,000 mAh each

2) Each motor gets 5S2P w/max 12,000 mAh each

You cannot run 10S2P on each motor. Both motors can pull out of the same 10S2P/12,000 mAh pack

Here are the current IMPBA FE rules. The rules for twins are different than those for NAMBA.

Are you sure? The 1/8 scale rules still list the 3 motors. One of which I haven't seen new of since about 2007. I could have sworn therewas a mah restriction for scale.

I never noticed before. IMPBA has no mah restrictions for any classes? 80mph offshore anyone? 10s3p on twin 3080's in a 60" cat. Azinga!

I know I've bagged on IMPBA over the years but you really really need to get a current version spit out that includes all of the rules that show up in the rooster tails.

With 41" hulls, you're locked into T offshore or T hydro. Not a whole lot of racing to be found for either of those classes. You might be better off tuning them to run in open offshore against the gas and nitro boats. Mostly it depends on what they are racing locally.

[JIM MARCUM]

Brian, I don't think the gas & nitro guys would like us running in the open class. I hear they hate to loose.

Yea, I'm pretty sure the rules I posted are current. They were posted by the IMPBA President a little over a year ago. I believe the only FE change since them were a few classes added for record trials.
I suppose if Zenoah stopped manufacturing the 260, than it should immediately be outlawed in the Thunderboat class??
The IMPBA always appreciate your input and will take your suggestions into advisement.

Sorry Chilli. I know I can be a wiener sometimes (sometimes? haha). I know you guys are working on it. I also know that like NAMBA, IMPBA is made up entirely of volunteers.

No mah limits is a little scary. Especially if you found a gang to let you run open with them. Do length limits mean anything without mah limits? I'd have to think on that.

I also read in there a lot of US1 regatta stuff. Has anyone ever been to an electric event capable of running heats, SAW, and 2 lap trials at one venue? I like the idea but it's pretty complex and the time to do it would be well.....lots of it.

Jim, that's just funny right there.

Here are the current IMPBA FE rules..

Those are not the most recent rules (the "secret" rules) which we are sometimes teased with in forums. I spoke to the IMPBA President in October and was told that the most recent secret rules were not on the website at that time. I don't know if they have been apporoved by IMPBA management or not. When they are approved they may be a lot different than what is currently on line.

[Doug Smock]

Chilli you are correct those are the current Fast Electric rules with the exception of the N Stock and Super stock classes that are for records only.
The only change to the rulebook with the update in regards to the Fast Electric classes, will be the addition of those classes.

Any rules that have been voted on and passed by the membership that are not currently in the rulebook, have been published in the Roostertail for a minimum of one year.
There may be those that think they are secret because they don't read the publication.
