Need for speed never ends! Daren’s suggestions to detail tweak this boat will increase the speed and stability for sure so it has to be the starting point for every newbie with Formula Fastech going faster. After that she was upgraded by the new prop X642 from OSE, motor and ESC stock with second cooling line just in case. Speed went up to 38.9 MPH!!! No temperature problems, all below 90F. Next, COG was shifted back by moving the batteries farther back and prop strut was adjusted to get her nose little bit up from the water. With this set up she was fast but less stable. I went to the pond again. Alone this time because DOBY was out of reach and I could not make him join me at the pond with his GPS. This time my Formula went to water with FEIGAO 540 8XL motor and Castle Hydra-120 ESC powered by 2 x 2500mAh 25C 3S batteries, STOCK PROP! This was such a surprise I could not stop enjoying this boat on the pond. Very fast and STABLE! No GPS 
. After 2 round’s I have changed the prop to X642 with the same power setup. This time she was very chine walking and less stable, good environment to dive the boat on corners! Back to the shore for switch of power plant again and back to stock prop. Next setup was FEIGAO motor, CC Hydra-120, 2 x 5000mAh, 40C, 7.4V, 2S, Thunder Power batteries. She was FAST!!! No GPS . This boat was so cool to play with I could not believe it’s actually happening! I think speeds went all the way to around 40MPH for sure. I will have GPS next time to check my testing and snap few pictures or perhaps video if other guys will join the pond. I am planning to do the same testing on my BJ that is still waiting for the Fullers hardware overhaul to come back from the shop.
Conclusion:
-Larger prop like X642 with stock power plant, good 2 x 7.4V LiPo 2S batteries and micro Daren’s tweaks will get you speed’s on straight run up to around 38MPH but the boat will be less stable and slow at corners.
-much faster setup will include higher RPM motor, higher AMP Esc and 2 x 3S LiPo batteries but need to go back to stock prop! My testing with higher power plant and larger prop did not do huge magic and with higher speed’s boat was not stable enough to blink your eyes. Never mind the corners.
That is it for now. There is not too many posts of how to mod your Formula Fastech so I hope this will help a bit. I like my boat a lot. It is not as fast as my UL-1 will be or DOBYS new pet but I think Pro Boats Formula Fastech is great to have for newbie like myself getting in to it……….
