    Default JAE33FE Build

    Here is my JAE33FE that I am close to completing. It will have TP 4082 2310KV, and Swordfish 220A esc, the rest is the complete combo from Zippkitts.

    The beginning, doesn't look like an RC Boat..

    Taped it together to check out the size.

    Lowered the battery height for more room, need to clean up a bit.

    Thank you, they are really nice to build. Received the batteries today, need enough power for the TP motor, so I went with Gens Ace - 5800mah - 100c packs.

    Will do, had a small typo its the 2310kv.

    Made some progress, hope to maiden tonight. The only thing I would like included in the kit that is missing, is a stand. Would be nice to have a stand that is laser cut with Zipp logo. Not that they are hard to make, would be a nice option.

    Just have to sharpen fin, and attach sponsons

    Turn-Fin sharpened and attached.

    Might need to paint brass thumbscrews black, pretty much ready for maiden. What would you guys suggest for props to test? I put on an X442 to start and get setup right, then might try the provided 1450, or ABC H7.

    I have a 12 I just built and went with electric right now it has a leopard 2860 5050kv 2s 56mph with abc 1514-17-45. I have a Tp 2940 2800kv im going to be trying on 4s.
    Im working on another 12 right now im going to be putting a Tp 2940 3770kv in it on 3s.

    Jim, not sure if the JAE would like the 19 series lifting prop due to the Ski which does the lift. we are now trying to reduce lift by Tip Cupping the props for more blade in the water.

    On the right track with props then, noticed others used those and wanted to confirm.

    Maiden went well, no mechanical issues during run! It definitely wanted a larger prop than a X442. I also had a decent amount of drag from turn-fin, so I will re-work and sharpen some more.

    Very nice, did you modify a lot, or make things fit within the existing nitro design? The motor could probably go where fuel tank is, but any issues with battery placement and interference with boom tubes?

    My only small critique was that the kit did not have a stand, huge thanks to Zipp for the laser cut one! Great service! (I did modify slightly to show off paint job.)

    Did some testing at my subdivision pond. So far I think the H7 prop performed the best.

    I'll have to order that one, I had 1450 from the kit, was looking for an H7 during the build and picked one up when OSE got an ABC shipment not long ago.

    I am starting two of them. Lots of boats but first riggers. Using 4082 1600Kv on 6 cell. Should be about same prop rpm as yours. Did you decide on which prop you like? Any other tips now that you have it running? Thanks, Bret

    I haven't tried the 1915 yet, but I like running the H7. I had to upgrade from the EC5 connectors because on 4S my amp draw was heating them up, might not be an issue for you on 6s or if you already have good connectors.

    Other tips:
    1. Lower battery tray height as much as possible, either cut out some of bracket or thin out main tray piece. Even though mine are already lowered, its a tight fit with the packs strapped in. I'm waiting on Mojo 4s 6K mah battery packs to see if I can get them to lay horizontal vs on edge in my pictures. I can fit up to Gens Ace packs with 47mm width (25mm height) on their edge (too tall to run flat = 25mm x 2 = 50mm). The Mojos are 48mm width (will be really tight /not fit on edge) and 18mm height, if I lay them flat, 18mm x 2 packs = 36mm. 36mm is below the 47mm battery height I currently run and already know boat can handle more than 50mm wide packs. Mojos packs might be a good solution to my battery height.

    2. Come up with a way to mechanically secure the hatches. I added thumbscrews to this Jae, but on my nitro I didn't. Having the hatches fall off in transport is unavoidable at times, don't want them getting broken / scratched from falling off especially if you took the time to paint.

    Other than that, nothing really. Boat runs great as expected.

    Thanks for the information!!!! If I figure this right you run about 6000 mah total with 2 - 2 cell in series? For same run time on 6 cell I would need 4000 mah (2/3 the amp draw) So 2 - 6 cell 2000 mah in parallel would be the same. I like parallel set ups because each battery/connector only "sees" 1/2 the amp load.

    Welcome! What size packs is kinda up to the user goals as long as you meet system / space requirements. Don't know if you're racing or bashing, but doing the math can give you an idea of where you'll end up. I have 5k to 6k mah packs in use, I haven't timed a run and then checked mah used. If I had to guess on 4s with 5000mah I am getting around 3 minute run time with the setup leaving the 20% pack mah overhead requirement.

    Not as critical on 6s but don't forget pack capacity and C rating can be a limit as well, Ah X C rating = pack amp rating. 5000mah is 5Ah and a good battery pack's true c rating is probably around 30C, 5Ah x 30C = 150 amps potential.

    Just re-read your quote and wanted to clarify. You would need one lipo 6S 4000mah, two 6s 2000mah packs in parallel, or 2 3S - 4000mah packs in series. Series doubles voltage but keeps capacity the same, where parallel doubles capacity and keeps voltage the same.
