View Full Version : 2017 Season

12-08-2016, 12:31 PM
Most of our club is already aware of the changes we've made for the up coming season as they voted on them. Some changes are major and some minor.

The biggest change really is organizational.

The club voted unanimously to become an IMPBA club.
Meaning that IMPBA membership will be required of each MMEU member.
Also meaning that our annual Michigan Cup will be an IMPBA event.

In order to continue racing the classes we have been running we needed to bridge some gaps in the IMPBA rule book. So we have adopted some club (club only.....club......only) rules to do so. Each of these new rules were voted on also. Some are adaptations of NAMBA rules we've used for eons.

IMPBA has no "limited" rules at all so we came up with our own based on multiple conversations and testing by multiple club members.

So we now have "M Spec". This too received 100% support by the membership.

34” Maximum Length
4s Lithium Polymer in accordance with IMPBA rules. (no mah restrictions)
Single motor
Motor to have a can size not to exceed 37mm x 62mm. Any number of poles. Any KV. Any manufacturer.
Any Speed control

Our club classes for 2017 will be:

• P limited Mono – Will now be known as M spec mono
• P limited Cat - Will now be known as M spec cat
• P limited Offshore - Will now be known as M spec offshore
• P limited Sport - Will now be known as M spec mono
• 10th scale (replaced SV per vote)
• P Sport hydro

We will attempt to gauge interest in additional classes and will include them on the sign ups for each race. Only one additional class will run. Only the class that with the most additional entries will run. There will be no trophies for that class. At the meeting there seemed to be a lot of talk about P cat if you interested in that. It will be up to the racers to organize themselves well enough to get enough entries to run that additional class. Basically......yer on yer own. Get the entries, we'll run the heats for you. I think somewhere we were requiring 5 to fly but I'm pretty sure we opted for 4 because we could.

As there are no IMPBA rules for offshore either we had to produce something for that. There was some apprehension as this is a departure for us. This only received 75% approval. Some of us have raced this new format and liked it so we're trying it. We'll give it another look at the end of the season to see what guys thought. The major difference being that it's 8 laps instead of 4 minutes. Still the course with extra turns though.

Reads thus:
M Spec Offshore Class:

The intent of the class is for the boats to “look” like real offshore race boats. This is not a scale class.

A. Hull Specifications

Offshore hulls must be a Deep-Vee (16 to 28 degree “V” angle) or Offshore Catamaran type hull.
Stepped hulls and flat keel ride pads will be allowed on both Deep Vee and Catamaran type hulls.
Closed cockpits must have windshields. Windshields can either be clear, tinted or colored. Open cockpits must have drivers. Boats are to be decorated with paint and or by graphic applications (decals) which must include at least two real or fictitious sponsors.
All boats must have numbers printed or painted on the hulls above the waterline. They can be either fictitious race numbers or IMPBA membership numbers. They should be as clearly visible in relation to the size of the hull as they would be on a full-size race boat.

B. Power specification

Motor and batteries shall comply with M-Spec.

C. Race format

Heats will run on an offset course for 8 laps and scored in accordance with heat racing rules.

The switch to 10th scale from SV received 91% approval. The obvious problem being that IMPBA doesn't have 10th scale. So we made some up for that too. These tooare a departure from the NAMBA 10th rule set in that we have opened up the motor choices. The motors available in the NAMBA set is dwindling so we took a stab at it. We may find that at the end of the year we have to make an adjustment.

So.....10th scale reads:

Electric 10th Scale Unlimited Hydroplane

The intent of this class is to replicate the look and competition of real unlimited hydroplane racing. Boats are 1/10-scale replicas (one inch equals 10 inches) of the real boats that have raced on the unlimited circuit. This class shall emphasize scale accuracy.

A. Hull Specifications:

Belly pans or blisters, if added, must be no larger than 2.5 inches wide by 4 inches long.
Air dams, if installed, must be below the deck line and unobtrusive and not extend beyond the bow.
An-hedraled left sponsons and modern style sponsons are not allowed on boats running in the vintage class.
Boats shall use a single rudder at any mounting location on the transom. The center of the rudder post shall not be located more than 1.75 inches behind the transom.

B. Drive Train

Any shaft may be used provided it maintains a straight line from hull exit through the strut.
No gearbox of any configuration is allowed.
Any single propeller may be used, and a portion of the propeller must be under the transom. The drive dog is defined as not a part of the propeller.

C. Power Specifications

Motors will comply with M-Spec except that they will be limited to 1700kv unloaded.

D. Power Limits

Motor and batteries shall comply with “M-Spec” accept that motor Kv will be limited to 1700.

E. Class Specifications

Vintage Class - Defined as those boats conforming to Master Hull Roster (MHR) numbers 2730 through 7008 inclusive, and MHR numbers: 7102, 7132, 7171, 7206, 7221, 7422, 7499 and 7505.
a) Skid/turn fin shall be mounted to the inside of the left sponson and shall not extend beyond the back of the sponson. The size is limited to a maximum of 2 inches wide by 1 inch deep measured from the sponson riding surface. No hook shaped skid fins are allowed

2. Modern Class - Defined as those boats conforming to Master Hull Roster numbers 7025, 7029, 7175, 7177, 7207, 7251, 7325, 7402, 7441, 7455, 7495, and numbers 7571 through 0717 and beyond.
a) Any shaft may be used. A curved stuffing tube is allowed in the modern class.
b) Sponson design shall be up to the builder as long as it does not change the outline shape of the hull.
c) Skid fin can be any size, shape or angle but can’t be bent or hooked in any way.

Holy crap is it hard to get things to format right on the forum. ugh.

We're really fired up for the 2017 season. More of what we've been doing. Just under a different banner. The 10th scales are a scream to drive and even a scream to watch.

We do have a tentative schedule but it's really early to commit to it. We'll be looking to miss some of the local gigs and their dates aren't fixed yet. Look for that after our next meeting. That meeting should be early February just before the Winter Warmups.

So your club races are void of many open classes. Do you plan on running many open class boats and if so, when?

Like P mono, q sport, etc...

Basically, should I give up on some open classes if they will rarely run, if ever?

I have no problem with parting out p mono and a few others to make my life easier.

I'd like to whittle it down to a few spec boats, p sport and or p hydro and q sport until the packs puke.

The Cheetah well... I'll keep it. Too much work into it to abandon now.

Ray, that's just the district races.
Missing from Toms list is the Cup and all of our club races. Only the cup will be sanctioned.

The cup classes will include what the cups of the past included but with the tweaks above.

MMEU welcome to the IMPBA from the Southern Ontario Model Boat Club

Thanks Tony. This season should be a hoot.

I was just looking at my schedule. I have 14 events on my calendar counting the Winter Warmups in AZ. Yikes.

I'm looking a building a 1/10 scale. Does this class race counter-clockwise?

Todd Fleury

yes, what kit are you using?

Looking at ML Boatworks

01-24-2017, 11:36 AM
Tom! I'll give you a ring on the commute. We need to talk about the pond anyway. I already have our permit for the season. Wasn't sure if you guys insured through IMPBA. No point in all of us trying to insure it.

10th scale is a scream Tom. You'll totally digit. The ML kits really are stellar for this class. I haven't seen one yet that ran poorly.

I plan to build the Tide hull from ML next. If I can ever get Todd's boats done that is. Every time I think I'm caught up he hoodwinks me into skinning something else for him.

It is a gift Terry. I'll be sure to bamboozle you again before the start of the season.

Always loved the scale class, the electrics seem like lots of fun. I'm looking at the 80 Pay N Pak. I have an 1/8 Scale of this, and just like all the Pay N Pak boats. It doesn't look like Mitch has a cowl for it yet, so need to figure that our first. If I can't get the cowl, gonna look at something else.

Each club gets one pond covered when they register their club. Your right, no need to have everyone insure it. If you guys run at another place, I can ask Lynne to cover that one as your primary, and have the Transom Twisters insure the Ford Field pond.

You could make one from foam. Then glass over foam.

01-24-2017, 12:50 PM
We also host at Shadow Lake up in Leonard. Those are the only two locations. Haven't registered us yet though. Slack'n.

01-24-2017, 01:08 PM
I have 6 boats in the works still not counting Todd's scales. I clearly have a problem.

At least yours are in the works. I have no place to build at Wendy's house. She gets bent when I go back to my apt/man cave to do stuff.


01-24-2017, 05:18 PM
Wendy's a great catch though Ray. You do what she tells ya or else.

My wife is at wits end right now with our boats all over hell's half acre.

Careful Ray..I might copy and paste this on her FB page...

Go ahead. I'm talking to her right now about issues.

01-25-2017, 09:16 AM
We all got issues, Wendy's a Gem. Terry is right .... do what your told, or else !!
Cheers, Jay.

Yeah, I meant "don't make me come over there and smack you around for her".
