I have just finished the refit of my carbon Falcon i ran it for a full season with twin 700 size HET motors on 8s per side i have upgraded to twin 780KV (2028 motors) i will start off on 55mm 3 bladers on 10s per side and work from there
Falcon 41" rebuild

You're freaking nuts man! You're running twin 2028 motors in a 41" boat I would love to see video. The motors will laugh at 55mm props, if you get bored of the water wheelies your boat pulls you can probably ride on the boat for some time lol. Looks great, clearly a lot of time was spent, look forward to a running video.Comment

(i have a large selection of 2 / 3 blade carbon props once i find a good balance with handling, run time and speed i will change for metal )
Cooper had no issues running the turnigy ESC's with the HET motors will have to see with the 2028's they may warm them up a bit
iridebikes247 i have cut the struts right back to the transom this should help calm the wheelies down a bit and help with porposing also i have the option of trim tabs if needed ( i went for the high powered option because its easier to calm a fast boat down than try to make a slow boat faster ,,,,, start fast and work back )

As if it wasn't mad enough already Phil, "prepare for ludicrous speed."

Thanks Paul,
I ran it today for the first time, runs very stable without any porposing and turns like its on rails the extra weight helps the ride and turns BUT i am well out on prop choice with the 55mm 3 blade from start it revs its "nuts" off and hardly moves away it takes half a lap to get up to speed my thoughts are 62mm 2 blade next time ( any help on this one would be most welcome )

3rd / 4th pic with trim tabs fitted made it more driveable but less funComment

Nothing at all, I swapped my 8s Supercat setup into my 29" mean machine after I wrapped my Supercat round a buoy in Friday practice and wrecked the hull at a nationals a while back, it was a lot of fun but too small to handle the holes Pete's big hydro was digging in the water though.Paul Upton-Taylor, Greased Weasel Racing.Comment

just my two cents here, but tabs have no business on a cat. i understand your boat is massively overpowered, but i would pick up some sticky backed motorcycle wheel ballancing weights. add them to the boat as far forward as possible inside the hull down low in the sponson. nice thing about this is if you add too much, pull it back out. again, just my opinion here!!

calculations for this size motor say 60mm 3 blader or 62mm 2 blade is just about right thought i would pinch another 1mm its going to be a bit overpowered with this setup anyway so i bay have to shave a bit more off to calm it down ,
i know i have said it before i have found it better to build an overpowered boat and calm it down than try and make a slower boat fasterComment
