UL-1 Upgrade Help

[papa]

these riggs are alot of fun for a RTR !

Yeah your correct they are a perfect RTR FUN BOAT no way are they ready to race if you are to upgrade power plant. Guys the mods I did on this boat I feel are required for seriuos electric racing and above all I want it to last me a couple of seasons

What a friggin joke! Still a fun boat with some mods though!

Is it possible to plug in a 7.4v 2 cell 5000mah lipo and 14.8v 3 cel 5000mah lipo in series to a stock UL1? Will this damage the motor or ESC?

[Brushless55]

A 14.8v battery is a 4s pack, 3s pack is 11.1v
running 5s or 6s could damage the esc

[basilpg]

My mistake, I didn't mean a 14.8v but running a 7.4v and a 11.1v in series. Could this still damage the esc?

Might want to be carfull with that voltage.. The ESC is only rated up to 20V.. that is the edge.

It may have an over volt protection..
so running 5s may not work

I gave it a try and ran it for about a minute. Managed to get 57.4mph (Garmin gps). The esc got very hot. I think I'll upgrade the esc to a Castle Creations Hydra HV 120. Is this advisable?

[Rumdog]

I would go with the ETTI 150 race.

[basilpg]

If I go with the Etti 150 do I simply plug it in and go or do I have to do programing to the esc to match it up to the setup.

Hey,
How did those 4s packs fit??? My PolyRC 4s packs make the hatch buldge up.

1515 1y 2200kv...

UL-1 was hauling ace using the m445, but the smaller m440 was esier on HYDRA 120 esc.

Your 1.5y 1500kv motor with 5s lipo power pulls less amps I am sure.


Here's my setup in picture

I want to clarify... ALL boats shipping FROM US after 6-15 are updated..you must (for some reasion) gotten ahold of an older unit..
