Default Pro help needed great planes wildcat I think lol

Whatís happening lol
Need a little pro help since Iím new to the Rc boat world. I received this boat from my dad and was wondering how to improve it.


I think after research itís a great planes wildcat boat with twin 550 brushed motors.

I would like to restore it since it was my dads and would like to know the best parts to put in this. So figured go to the pros. Lol

Right now I have a list of the following but havenít purchased them. Would like opinions


Please let know what you guys think and if there would be a better solution

Depends how much money you want to spend. The most expensive would be to install two new brushless motors and speed controls with a couple of 2 cell (7.4v) lipo packs (you'll need a LiPo charger but they can be had cheap). you could use he original radio but a newer 2.4 GHZ pistol would be better, but all of that is really overkill for a vintage boat. If the brushed motors are still good and the shafts turn and aren't rusted out just add a couple 2 cell lipo packs (check the voltage specs for your speed control and make sure it can handle 7.2 volts (about 8v charged) . You could probably run 3000-4000mah packs for the same weight of the old nicads (and have 2x the run time). Unlike NiCads, don't run LiPos down to nothing or they will puff (become useless) or catch fire. Run them down to about 40-50% and recharge. Do a three minute run and then come back and recharge and see how much juice they take. If more that 50% capacity remains increase the time in 1-2 minute increments. My guess is you could get 5-7 minutes run time easy. I like the packs from RCBattery.com. Good luck!

Great advice thank
you

looked up brushless motors and found a F540 combo with esc and have to get 2 f them since they donít make a dual brushless esc. Works out good though
They take 3s so Iíll have to get 2 of them found some with good reviews that are 3000mah

so I guess that would make the boat a 6s with both motors and 2 3s batteries combined correct?

No it's per motor so it's 3s. It's based on how many cells each motor 'sees", not how many cells the model holds (1s = 3.7 volts so 3s = 11.1 volts nominal vs. the 7.4v of a 2s pack) . Not familiar with that set-up. You may want to check with the boat guys on RCUniverse or RCGroups before you pull the trigger. If the boat was ever run (especially in salt water) I'd check at the fittings/shafts for corrosion before dropping a bunch of money on a boat you can't get parts for. Those motors may need cooling as well. That would be another question to ask. Normally in cars they have access to air flow, not so much in a sealed boat.
