    JetChopper30 on P-Power

    After setting, and currently holding the NAMBA P-Ltd Mono SAW record with my first JetChopper30 and building a "hotrod" version for Christian Z. in Chile, I decided to build a hotrod for myself. Having just decommissioned my Wacko dual rudder MM and having a spare Catle/Neu 1515 1Y 2200KV motor and a T-180, I set out to have some fun and add a litle bling.

    I'm a fan of Spd stingers but I needed to shorten it to have the correct relationship with the Spd .21 rudder, which was shortened

    OSE tabs and large fins. (three holes for bling)

    To spread out the motor mount load, made some platforms for strength

    [I started with a Promodel motor mount that had the useless-for-inrunners front mount which recessed the motor bolts and made them hard to line up. Instead used an Etti center section which I added a top bolt to keep things lined up.]

        3/8" brass tube for servo rod to pass-through without binding on full articulation

        5-31-13 080.jpg

        narrowed the T-180 since it was getting placed next to motor in tight quarters - (hopefully one day the trusty T-180 ESC will have the water inlets/outlets going the same directions as the wires) Made a platform for the ESC to anchor it

        5-31-13 099.jpg

        Favoring the "rear-motor/batteries-on centerline" design to keep weight low & centered (which I presume minimizes chine walk) (btw it worked) I made 3/32 birch ply battery trays spaced off the bottom to allow one-wrap velcro to keep batteries from strolling around and G/Flexed them in with holes to add epoxy strength/bond

            The HRC water jackets come with small diameter fittings; replaced with larger ones after re-tapping holes

            5-31-13 096.jpg

            same for rudder

            5-31-13 097.jpg


            Waterlines short and neat inside

            5-31-13 107.jpg

            Angled outlet makes output easier to check - less wind-shear effect

              I'm a big fan of hatch retention. Tabs in front

              DSC04552.JPG

              CF in back with tapered "locators" (CF can be tapped with threads!) BTW in this picture you can see the Etti center motor mount with easily accessible bolts

              5-31-13 094.jpg

              Purdy 4mm anodized thrumbscrews through rubber grommets

              5-31-13 092.jpg

              (somehow an FE30 picture snuck in & I can't figure out how to back it out )

                  I usually don't record the first wet but I was alone in the park until a bunch of kids walked by so I commandeered a 9 year old girl to take the vid. I'm happy with the way it ran; need to center-trim the rudder and bolt on a bigger prop, but looks good so far :

                        Some say that ride-pad hulls have trouble in chop. My P-Ltd JetChopper30 doesn't seem to mind http://www.youtube.com/watch?v=qkiTfVT1LaE

                              Yep I was cruising along admiring the build and then a yellow Fe 30 pops up . Butterflies and nightmares.

                              On a brighter note I'm pretty stoked on how my pursuit is running with some tired batteries , can't wait to pick up my dinogys. Not sure how long it will be before my new hatch gets here so I made one that looks good from 50 ft away. Also got a nice big rudder on there, huge difference.

                              I'll be running p ltd cat next weekend, assuming the boat min. Is met. Could use a tune day before hand, water is usually flatter down there then when I run up here. Might have some free time mid week if you are gonna run at all before the race.
