Motley Crew Leopard 4074 install

[Pete32200]

The UPS man dropped off my Motley crew this morning that I bought here in the For sale section, I proceeded to gut it and install carbon fiber in the hull and hatch, a new motor mount, a B/S X445 prop and an 1800kv leopard 4074 motor ( the seaking 180 and upgraded flex shaft were already installed )

Nice job man! Glad you are going to get some use from it ! Just a note... I tried that deans connector thing.... They will get hot....mine melted a solder joint, but once I went back to 5.5 on the batts it was all good.
And with that 1800 kv setup the only thing that probly will get warm will be the batteries!
Good luck!

Stopped at the lake on my way to work this morning, it was running a little wet but handled great and it seemed like low to mid 40's speed wise, I think I can get a little more speed by adjusting the strut and CG, right now the strut is adjusted so it sits flat and level on the set-up board.
The motor, all the connectors and esc were all under 100 degrees after 4 minutes of running and the lipos were 105 degrees.

You can turn a prop with more total pitch using that 1800kv Leopard...................an Octura x642 would get you a good speed boost, dont know if the hull wants alot of diameter but you could also try an x447.......

[Pete32200]

I may have to try one of the x642's....I have a 42x55 and x440/3 I still want to try

I got near 50 mph with an m445 and the stock 1800 Kv PB motor in mine. You should be able to spin an m545 or m645 with that motor depending on temperatures and the speed you want. You need more pitch than an x440 has to go fast.

Yea that motor can swing a nice prop. I am running a x447 on my 1800kv leopard and it runs good. I run it on 4s1p, but like fluid mentioned a m645 would be better. I run a m645 on my Leopard 4074 2200kv in a Pursuit mono on 4s2p. Runtime suffers but shes a batt outta hell. I would even say maybe a s225 might work. DOn't trust those deans they ARE the week link you setup right now. Get rid of them asap!

I have 10 pairs of 5.5 bullets.....I guess I will go home and start soldering

i suggest that you stiffen hull up or add the 2 part foam to inside if you plan to go over 50mph. my boat is coming apart from bad crashes over 50mph. seems like the hull flexes and cracks/splits. i believe if you fill with foam like the ul-1 guys are doing it will be ok. im in process of trying to get new hull now and fill it with foam. good job on your build. good luck

When I was up at Kintec racing picking up the CF and motor mount Jan was telling me I need to foam it also, I am just afraid I will add too much and split the hull

http://forums.offshoreelectrics.com/...L-1-rock-solid is a link to article on 2 part foam. if u use the 2 part foam it is light and will not break boat. if u use the foam from home improvement stores you will have a problem.

LOL I should use mine as a plug, make a mould and build myself a carbon fiber hull, see what the design is really capable of, I bet it's impressive if you're not afraid it'll blow apart!
Wonder if you could cut the deck off, add some carbon fiber to both the deck and hull and glue them back together?

i think poping the two pieces apart can be done. looking at mine were it is coming apart it seems to be like a shoe box(bottom and lid) i called aquacraft and you cant buy a new hull so im gonna have to add the foam or split the two halfs and add some material. at 60+ mph the crashes ive had are not good. next one will prob blow the boat apart. almost broke off right front part of boat(were it comes to piont about 2 in back cracked 80%around) split hull at seams(2 inches from back all the way around, in front in between the fork) also crushed in lid, stress cracks bottom center of hull in tunnel, and on right sponson on bottom(bad enough to take gelcoat off) i believe you can reach 70+ mph with no problems if you foam the inside.

Just don't crash and it will be ok. Lol. Just kidding

yeah i wish it was that easy lol!
