I'd take that motor mount out and put in an OSE style one... )

    But, that's just me... :D
    Darin, I have tons of this cool angle stock & tried to figure a way to employ it. The CF reinforcing seems quick & workeable - the CF plate I have is quite thick and rigid as a [ insert metaphor , may use term Viagra if needed]. The bottom mount needs to have bottom deck really stiffened; it's very flexible.

    Here's the CF reinforcing plate. I will laminate with G-Flex as well as being anchored by side bolts and motor attachment bolts. Clean, simple (could be an inventoried add-on) and RIGID. This is a spare mount I did; when I pulled the original one off it WAS bent.

    Temps seem ok with the upgraded cooling - a 445 on some spec powered hulls get the motor quite hot. I still need to do a full 2.5 min test to confirm that temps will be sustainable for a full race..
    Thanks Tony. Picture is saved.

    BTW i use a STRONG pair of reading glasses (+3.00) whenever i thin and sharpen my props. You can buy these really cheap at Walmart.

    Good idea. I always wear magnifiers for up close work while my contact lenses are in. I get them at the .99 Cent Only store.

    I wonder if you make the rear riding surface more sharp and square edged, would that make hull faster. Also sand hull bottom with 1000 grit paper may help. These are Old ideas, but everything helps. You could probably do this without messing up factory finish too badly.

    Default Stiffening/reinforcing complete

    The CF plate bolted/laminated to the stock motor mount did the trick - way strong & no more flex. Seemed like a clean and easy solution. Supported the shaft with nifty goodie. Epoxied lightweight aluminum angle rails to stiffen floor. Did the trick-no more trampoline floor. Time for a cheeseburger

    Note to all :

    All these mods were done 'cause I like to play with boats and I'll be racing against the best of the best so so a little bolstering was in order 'cause I intend to push this boat hard. For most purposes they weren't all that necessary. Actually this boat is so striking that I hate to get it in traffic . The MC right out of the box is very cool as delivered, and along with several other recent rtr's has really raised the bar for all of us.

    As you all know we had the 2030 out on the market before the Motley Crew. During testing I was just not all that happy with the current draw with the 2030 in the crew. Sure it would have worked but I wanted just a tick more run time and a little less current draw.

    I messed with props and started testing the new 1800 we had been working on in the boat.. BINGO.. just right.. A great balance of speed, power and power consumption.

    I have quite a bit of data logged regarding the testing of the boat.. fun to look back at all the hours of design and testing that went into that boat.

    BTY.. EVERY ASPECT of the hull and hardware were designed and tested here in the US BY ME.. no pulling the wool over the eyes of anybody.. If it sucks.. I TAKE FULL RESPONSIBLITY.. if its fantastic.. the same.. No pointing fingers or any of that BS..
    To bring it to market however adds a ton more people..

    Have fun with the boat tony!.. love the tip paint!

    I have one of these on its way from Tower!!
    would a M447 be to much on the stock motor?
    I don't have a M445 yet, but I do have a X645 along with the M447 to try..

    Todd,

    There's some propping discussions here; check them out. The 1800 motor should spin a 447 but you know the drill : run for one minute/check temps. The hull does run fairly wet, so be carefull not to load the motor too much.

    Ok Tony, have you had a chance to race this Cat yet?
    My plan is to race it at the Nat's in the Ltd Cat-Sprint class. I took it to the 2-lap last weekend for P-Ltd Offshore, but Tyler ran his 26" DF mono and was untouchable - I did burn up a 2030 motor with an MM545 'tho.

    thank you!
    sorry to hear about the HOT 2030 motor...

    what is a good way to loosen up a Cat other than moving the packs farther back?
    My MM ran very wet..

    I really, Really, REALLY think it's time to re-evaluate some of these "record" titles and start calling them what they really are.... It seems silly to me, and this is coming from someone who has held "Offshore" 2-Lap records, to be setting 2-Lap... or SAW, records... for a class called "Offshore", which really isn't a "class", but is, rather, a RACE type/format...

    Records should be held for HULL types and Power system levels... not for "race formats"...

    With that said... I think it's time to establish a "Cat" class...

    Add castor oil to the cat food - Oh wait ! Truth is both my MM and the MC appear to run wet; it's a product of cg and strut angle to get the sweet spot. I'm setting mine up "wet" for the race; racewater and headwinds will cause a balanced-for-smooth water setting to get badly upset.

    Gas cats run really wet and plow through the corners but can corner at WOT. Seems both the MM and MC are designed to duplicate this. My Drifter barely touches the water on the straights but corners like King Henry VIII


    My MM ran very wet..
    You'll have fun with the boat; a little test/tune is always part of it.

    Darin,

    Haven't used one so far; corners really nice for sprint course radius turns given that the end point/dual rate is dialed in correctly. I'm finding that cats do corner at different radii with the same rudder deflection depending on the speed of turn entry. The skeg strut might help in this. Different than piloting a mono through turns and takes some practice/retraining on the wheel.

    Did some practice driving yesterday; the MC is running BADASS & can't wait to get it on the course. No vid, but did some strut & CG tuning and LOOKOUT

    Mike, the MC is ready to rock the 6-lap Sprint, but B & D will be hard to beat

    Am considering it also for entry in P-Ltd Offshore; just happened to have a larger SPD rudder which (go figure) just BOLTED ON the stock MC bracket for more control in the lefties. Added a funny little goodie in front of the motor as well

    Will be doing more test/tune this weekend. Keep 'Ya posted

    Ray, I got mine at the PureTech booth at RCX - you can order direct from them; they're in California. The double straps sewed to velcro ont he bottom are slick; have them in my JC30

    I did mine last year, Had some fun with mine today, Castle 1512 1800kv with a tuned x645, swordfish 120. FAST!
    Went out early and had perfect no wind glass smooth water. Was on the edge!
    If my boats upside down then who owns the one I thought I was driving the last two laps?

    Default Experimenting with strut & CG

    After blueprinting the bottom (and putting a slightly larger rudder on) took her out for testing. This time I had the strut @ 1/8" above sponsons and 3-4 degrees positive to keep the nose up under full throttle but the cg a little more forward to let the hull settle for turns by letting off the throttle a tad. Very pleased (as was my pitman, Bowser Woofmeister who voiced his encouragement during the run - after all he was watching a Cat do its thing )
