Whiplash 20 power questions

[siberianhusky]

One or the other, Ul-1 2030 kv running 4s 5000mah or Castle 1515 1y running 4s2p 8000mah with a T-180.
From my other hydro I pretty much know what to expect with the spec 2030.
What could I expect in terms of speed AND handling for running ovals with the 1515 setup?
I have both power setups, haven't installed the motor mount or stuffing tube. Speedmaster hardware on the back.
Waiting until I decide what setup to mount the motor so I can set the CG.
Will be a .150 cable for the UL-1 or 3/16 if I go with the 1515.
Those are the only two options I have on the bench at the moment so I'm not interested in Leopard or TP suggestions. Nothing against those motors I'm simply using what I already have on hand.
Thanks & Cheers

I have a Neu 1515/1Y in mine, 4s2p 5000 and a H-7 gets me 63mph reliably, but I wish I went for 8000mah, it's kind of heavy, especially in turns. I topped that setup out at 71.7mph with an aggressive prop last season for short runs. Threw a 5s/5000 in yesterday just to see, and I got 70.5mph.

If it's a light build you can use the 2030 Ul-1 motor but, You can't prop much more that a 442 or 642. I'd use the 1515 you don't have to worry about heat as much

I have a whip 20 and have run it in p limited sport hydro and p sport hydro trim. It seems slow and boring with a 2030 after running it with the 1515. Go big or go home!

There you go. 'Mr. Hot Rod' has spoken.

Yep, think it's going to be the 1515, be my first P hydro. Already have another P-spec boat to beat up on the UL-1's.
I do have one other guy I can run it against, maybe some of the other guys will build P boats when the see the speed.
Thanks for the info.
Cheers!
