Fast "P" motor esc combo for a tunnel?

[boogaloo_d]

I'm looking for a fast "P" motor/esc combo for a tunnel. It will be going in a Leecraft XTR 21 hull 28-29in long. I'm running the UL-1 esc and motor in a different hull. Just looking for something faster to play with. That will run on 4s lipos. Any suggestions would be great I don't know much about brushless motors so any advise would be helpful.

On the face of it, a Neu 1515/1Y or a Feigao 8XL may be good choices. They will spin a larger prop faster than the UL-1 motor will. But I have not run these motors in anything but a hydro, so I'd wait on advice frrom OPC guys.

Are you looking for a "P" or "P Spec" motor??

[boogaloo_d]

Looking for a P motor. I've got my P-Spec Tunnel tunnel running 50-51mph. Ive got an extra hull I want to put it toghter as a P tunnel andplay with it maybe run it in Open Tunnel class.

As Jay said, a 1515 1y is a great 'P' motor!

[boogaloo_d]

I bought a 1515 1y a little over a year ago. Just never used it. It looked to big to mount on the back of a 28in boat, as an outboard. Guess I'l giv it a try. When looking for a better/fast brushless motor what are you looking for Kv, physica size of the motor?

Kris, Can the OS lower take the power of the 1515 1Y?

I hope so

Are you running that set up Tony or do you have something up your sleeve?

Mike, I'm right now building a new tunnel with a O.S. lower that I got from Mike L.
( Cybercrxt). It has the "Kris Flynn cable mod". It's currently being set up for
P-Spec-OPC BUT I do have plans to run a bigger motor like a custom 7XL I have or maybe a 1515 1Y (once I send it in to Nue for a tune-up ) in the future for an event next year

I talked to Mike L about puting a 1515 1Y on a OS a few months. He wasnt sure if it would hold up. He didnt say it wouldnt. He just hasnt tried it. I may slap that 1Y in my Woodstuff 30 next fall if it survives the heat racing season.

BTW- Sent my 1Y to Neu last month for a check up. Turn around was about three weeks and cost a little over $40 with new bearings.

Keep an extra cable and teflon tube in the toolbox. 50/50 ATF and STP for lube. Lube every run.

You may find the handling leaves a bit to be desired as the 1515/1Y will spin a much larger prop than the 21 size tunnels like to run.

I find that the 21 size tunnels handle best with 42mm or smaller prop.

Just my experience with TS2's, VS-1's and TS3's. I've been told that the handling goes away on the lynx with bigger props as well.

[Kris Flynn]

Even with an X637, 4S1P on the 1515 1y with a barra 125 I was getting 55mph 2 years ago

The OS will hold up for sure, but like Brian said, bigger props can cause proplems.

All I use for lube is outboard gear oil.

I also never run the stock cable.

wonder how my 1.5D will go on it? hmmmm

1.5d runs great on a 38mm prop. Hard on batteries and cables.

Good stuff guys. Thanks for sharing!!!
