    RE: HK Small Bolt Hydro same as HOTR

    Would that motor fit? What about shaft size? May need a new coupler.
    what about the ADS 300 motor from HK?

    RE: HK Small Bolt Hydro same as HOTR

    Get ADS 3000 400 watt will fit and has more power.- Landor 632/3 is a mistake!!! 632 as is is better and better yet. Take a 632 and cut down to 630 is the ticket with a hair 1 degree negative angle on strut. The 4800kv is overkill as it will make Bolt unstable and on 2S will end up running 35,500 rpm. I don't think it will hold up structure wise with the bouncing like the BIG boats do in Washington State. I've seen them run as I was stationed in the Army in the 60's and they do bounce hard and take a beating.-Now for prop work , I learned myself thru trial and error many years ago and reading the Prop Duplicator. Cupping the tips is for racers who do this everyday for a living. I see no need for me to do cupping as I use the pitch of the prop for more speed. I use 632 props on small boats with small lipos to keep weight down to attain more speed. I use no trim tabs and fairly small turn fins to reduce drag and my boats run flat on the water thru balance of items in boat. The ADS 3000-400 watt, I have them all, works great on 3S with a 630 prop. -I run monos and 1 bolt. The bolt has a turn fin on right sponson with a hook toward the inside and a little back and is vertical. BTW- that's me. I don't run boats on the edge as I like them to run stable. Have fun is the answer. This will be my last posting on the BOLT.

    RE: HK Small Bolt Hydro same as HOTR

    The ADS300XL? Isn't that overkill for the Bolt?
    The size 300 outrunner allone is already a big jump from the 2 pole 20 size stock inrunner.
    Please elaborate on your recommendation of the XL. And since you volunteered the prop modification, I would like to take advantage of the opportunity and ask if you canwalk me through cuttting down a prop and bending the tips to a certain degree? Won't this require some sort of jig for blade uniformity?Do you make a template of the blade face first before downsizing it so you retain the shape? Sorry for the newbie questions, I am aware that more experienced boaters do this stuff. It's just that my prop work experience is currently limited to SBP. Would like to bring it to the next level. Ifyou know of a turorial site, it would be much appreciated. Everybody starts somewhere right?

    RE: HK Small Bolt Hydro same as HOTR

    Just gone through 50 pages, there were a few questions raised as to whetheradding turn fins would help from flipping but there was no answer?

    Do you think it would help the bolt or just adding unecessary weight?

    Stock setup, no need for turn fins.

    RE: HK Small Bolt Hydro same as HOTR

    I haven't receive the bolt yet, should be here in a week. I have a spare 2040 4800kv, octura x432 so will be using that with 2s 2200mah.I assume It will go a lot faster than stock 3s. So with this setup, is still worth while adding turn fins?im ordering some parts overseas for my 1/8 car so was comtemplating whether I should add the fins to the cart also?

    I've been running the Small bolt on 4S 2p, 2s1800mah 40C using this prop. http://www.hobbyking.com/hobbyking/s...dProduct=18245
    It runs nice on 3s and nuts of 4s.

    On more thing, the prop took a little filing to get it to fit on the stock drive dog.

    Read all these posts...picked one up as my first hydro.

    Modified a Barbwire to 4S and plan on running 4s as per previous posts.

    http://www.youtube.com/watch?v=Ut6Wl-eG0xI (Barbwire)

    Using a 28mm dia. 18V max capable inrunner with oct. x632.

    Putting a bearing instead of bushing and see how this goes.

    As I understand, the Bolt can't handle any kind of chop.

    How often do you fellas flip? Just curious...if a recovery boat is a necessity

    during each outing.

    Appreciate all this information that has been shared.

    Cheers,
    P
