Planning to build a 54" Central R/C Mystic. Want to use dual motors, esc's, drives, etc. for scale looks. Not looking for a speed monster, 50-60mph tops. Would like to know what kv and cell count you guys would recommend for using some 5 blade props, again for scale looks. Not sure what pitch props to get either. I know prop shop has a big selection. My main concerns are scale look, handling, and run time. It'd be nice to go 10 or 15 minutes. Thanks.

Twin Leopard 4092's in the 1400-1600 kv range on 6s each will get you to those speeds. The 1480kv would be great..............NEED PARALLEL CONNECTORS?? QUALITY 5.5MM, 8MM, 8 AND 10 AWG, GET THEM HERE:http://forums.offshoreelectrics.com/...est!&highlight=

I wish OSE carried an x452/3 in both rotations, thats what i would suggest. You can get x450's in L + R rotation in the 3 blade. You may be able to use x457/2's which come in both rotations as well. If it were me i'd try the x450/3's.NEED PARALLEL CONNECTORS?? QUALITY 5.5MM, 8MM, 8 AND 10 AWG, GET THEM HERE:http://forums.offshoreelectrics.com/...est!&highlight=

5 blade props are a real pain to sharpen and balance, and not many people have info on how to prop motors with them, so probably start out with some 2 and 3 blades and work from there, a 5 blade prop same pitch as a 2 blade would need to be much smaller than the 2 blade to get the same amp draw. I personally wouldn't even know where to start w a 5 blade?We call ourselves the "Q"Comment

One would think the current draw would be high so runtime would suffer, maybe the right props for driving and 5 blade for show?Visit www.customcfparts.com | Custom Boat Building | Custom Carbon Fiber Parts | Custom Graphics | LMT Premium Dealer | MGM Premium Dealer | YouTube | Facebook

As noted here, 5 bladers are mainly for show, they dont work well with RC boats, you could put them on for show as mentioned. I really think the Octura x457 2 blades will make her rip. 5 bladers are very expensive, cavitate and are brittle.
EDIT* I have an x460 3 blade that is chrome and beautiful, but it runs worse than the berylium version, so I dont run it, I will put it on if I ever "show" the boat.NEED PARALLEL CONNECTORS?? QUALITY 5.5MM, 8MM, 8 AND 10 AWG, GET THEM HERE:http://forums.offshoreelectrics.com/...est!&highlight=

Als boat is waaayyyyy over built. But, that's one of the things I like about it. My boats gonna see some big water. :) Looks like I'm going to go that same direction. He's pretty much dead on the numbers I'm looking for. Might go 900 kv on 8s. His theory was 600kv on 12s is like 1200kv on 6s. Split the difference. Can't believe the runtime he's getting, 10-15 minutes...that's what I'm after. 100mph is great, but changing batteries every 2 minutes seems a little silly to me. Would rather do 60 for 15 minutes myself and actually get to use the boat.Comment

60mph for 15min is going to be sceince or require some large heavy packs 5 blade will load up the motors small props and big motors will keep the draw down and get you long runtimesVisit www.customcfparts.com | Custom Boat Building | Custom Carbon Fiber Parts | Custom Graphics | LMT Premium Dealer | MGM Premium Dealer | YouTube | Facebook
