21 inch bby oval racer build

[phase]

i got some more wood,metal,and glue.. the layout is much better, and im making a new rudder and turn fins now.. wish me luck!

Why new fins? the other ones looked good, as for a servo i would just stick with a standard sized servo.
As for the ruder, saw records have been set with that boat a rudder just like that, test it out first then if your unhappy change it.
Yes i did mean COG, sorry.

i just installed everything and all i need is 12 gauge wires.. the reason why im doing new fins is because im not necessarily gonna be racing on right ovals.. so i am making them both the same size as the bigger one.. also i have heard of stories going around the boat racing community here that they are way to short for any type of racing and it has to be longer.. it a little to late to go back to the smaller one cuz im lovin the one i made last night.. it is now a little longer.. the lenght of it is 2 1/2 inches.. i am gonna have pictures up later.. i got the mamba system but i am not gonna use it for the boat cuz i dont want to take chances in getting it wet and overheated. so i am gonna stick to the 11 and 12 turn motors cuz i got them for cheap.. i am gonna take it out as soon as i get the coupler and wires,,

Um, where do your batterys go?

[ReddyWatts]

The flex cable will shorten at WOT. Leave a gap between the strut and drive dog to allow for shrinkage.

its not done yet. but thanks for letting me know.. how much of a gap should i leave?

[phase]

the blue battery is for the fan and it will be on that side to help ballance the boat. all of the electronics (escept servo) are velcro'd on so everthing will adjust if i have ballancing issues..

[Mich. Maniac]

cool stuff, keep it goin. Cant wait to see some action shots!

[phase]

yes.. i need to get some money to get some wire, and coupler.. lol..

[phase]

hey reddy.. how big of a gap should i leave between the strut and drive dog?

[phase]

wow.. im a little stupid.. how could i install the servo without checking if the motor fits.. to my luck it doesnt.. well no im so angr im gonna have to redo the servo again.. this time im just gonna go with the mini servo and forget about the big one.. im so STUPID..

[ReddyWatts]

I would leave 2.0 - 3.0mm gap.
