Which Combo?

[G1ST]

I am finishing up a rebuild of an Ovalmaster 29 and I have 2 power combos I can put in it.
First is a KB 9L (2700kv), Seaking 90, 3S 4400mah battery and a carbon 42mm prop.

Second is a Castle 1512 (1800kv), Seaking 90, 4S 5000mah battery and the same carbon 42mm prop.

What do all of the experts think? I don't want to create a grenade.
Is either combo safe or should I set it aside until I can change out some components?

Any recommendatiuons are welcome

Thanks
Greg

That would be my vote. Might want to bump up to a 120 esc if you want long run times. If setup pretty loose the 90 can work.

You might want to prop up a little on the 2nd setup (1800kv 4S), but if you do, it would be a good idea to get a t120 or any other 120 esc.

The CC1512 running a M445 would rip

Thanks Guys.

I'll go with the 1512 on 4S.

Lots of expenses these days so I'm stuck with the Seaking 90 and the carbon prop for a couple of months. I just dont want to blow anything up.

I appreciate the help
