    The G-Force got some paint. Just the 2k clear coat is left.

    It looks great! I especially like the tub nose shape. What motor and esc are you planning to run?

    Cozy: my fast electrics

    I ran my 33" F1 T800 together with a mono boat. 2 different boats, with different power setups. But pretty well matched! Arrow Shark mono: Length 35" 6S 6200mAh 4074 2000kV Flycolor 150A 43mm 1.6 prop Weight ca 3500 gr. Cozy F1 T800: Length 33" 6S 5200mAh 3674 1650kV Turnigy Marine 120A 43mm...

    Thanks for the advice. I will try that 👍

    DIY twin motor mono build 'G-Force'

    Thanks for the advice Xtreme 👍 I will do that. The issue is, the brass tube holding the flex shaft is well below the water line, if the boat lays still in the water. In the beginning, with a freshly greased flex shaft, water is kept out. But after some running, grease is pushed out of the teflon...

    DIY twin motor mono build 'G-Force'

    I broke the rudder blade on a recent run of the G- Force. I made a new one, and took the boat out again. She ran pretty good, although this pond is too small too fully stretch the legs of this boat. I got 74mph with twin 3670 Rocket motors and 44mm 1.9 props. Basically a very budget setup...

    Cozy: my fast electrics

    Here's a compilation video, where I cover almost all setups that I tried on the Wildthing. From speed running to oval setups. It might be a good reference if you're running a 32" mono 😎

    Build thread: Cozy F1 T800 33" tunnel

    Thank you for the advice. I was aware of that and I inserted a glass section into my carbon hatch (front one).

    Build thread: Cozy F1 T800 33" tunnel

    I made some progress on the kit build. I started assembling the sponsons, sealed the tunnel with epoxy, and I made a carbon cowl. Here's the build video, part 2:

    Build thread: Cozy F1 T800 33" tunnel

    I made some progress with the kit build. I made a carbon cowl on my mold. I glued the sponson ribs and clipped the sponsons to the tunnel. The shape is becoming visible!

    DIY twin motor mono build 'G-Force'

    This weekend I ran the G-Force and I got some good results. I fine-tuned the stinger angle for the 43mm 1.6 golden props and I got a new speed record for this boat. After that, I ran with the 44mm 1.9 pitch props. The G-Force runs very stable with these props. Maybe a bit too wet, so I will...

    DIY twin motor mono build 'G-Force'

    You got a good point there.. I might add a side-brace too, as the rudder is actually more slim sideways. I didn't notice any rudder movement. I added the brace to protect the rudder from breaking when I flip the boat. I appreciate your input!

    DIY twin motor mono build 'G-Force'

    I made some improvements on the G-Force. I added a brace to the rudder arm, and I sharpened and balanced the propellers. I can't wait to take her out again and set some speed numbers. Here's the video of the modifications:

    Build thread: Cozy F1 T800 33" tunnel

    Thank you for your feedback Grimracer. I can image that, and it's something to keep in mind. I always fully glass my boats, so that will seal the hull.

    Build thread: Cozy F1 T800 33" tunnel

    Topic update; I worked on a laser cut kit of this boat and I started to build one myself. This kit contains several design upgrades, such as a bigger sponson deadrise for more speed and a lot of cuts and notches for a fool-proof and strong assembly. It is a frame kit, meaning the deck and...

    DIY twin motor mono build 'G-Force'

    The G-Force had it's maiden run this weekend. I ran 2x 2 lipo's and the boat handled pretty good. It has a little bounce and it spins out in tight corners, but I will work on that for the next run. I got 62 ad 64mph on the runs. It's a good baseline, from where I will work on increasing the...

    DIY twin motor mono build 'G-Force'

    Thanks Flemming, patience is the key factor 👍 Here's the next update. 2nd stinger is finally installed! Wiring and motor cooling is sorted as well. The ponds are frozen here, but I hope to run it in the next few weeks 😎

    DIY twin motor mono build 'G-Force'

    I finished the second stinger and got the motor wiring sorted. Soldering these motor wires was a pain. They are lacquered and need thorough cleaning before they can be soldered. I hope to do the maiden run next weekend.
