My xxl conversion
Hey finally got a new body and some new kicks for the old girl . i have been experimenting with motors in this truck , alternating a castle 1518,1520,and 1717. believe it or not the 1518 seems to have the most power ? i honeslty think i need a new 6s lipo to get the most out of the 1717. any way here are some pics .

Your current 6s may be tired but the kv difference also plays a role in how powerful it feels. This is especially true if you're using the same gearing with each motor. If you change the gearing to keep top speed the same between each motor the differences would become more apparent.
I've personally had all 3 of these as well. Loved them all, especially the 1518 and 1717. The 1518 is a little animal with a killer midrange. IMO the 1520 feels similar to the 1717 but a bit quicker to react to throttle changes than the 1717's larger diameter rotor when making mid air corrections. When compared to the 1518 the 1520 and 1717 do feel a little flat, powerful but in a broader, flatter power curve.

That beeing said my all time favourite is the 1520. It too needs to be pushed but my god the noise it makes is pure heaven! I've since never come across anything like it. My 1518 by the way is of completely diffrent nature (similar to the 1515), and have got me wonder if there's some unique variations going on.

Thing is the 1717 will easily deceive you, until you start pushing it. It truly is a beast on tall gearing and proper lipos, and not to mention the sheer weight that thing will push effortlessly is just amazing.

I don't think there's really anything special going on with the 1518 though. There was never any mention about design variations, it's even still a 1Y wind like every other Castle motor. It's just unique in its kv and I think the shorter length makes the rotor lighter both lending to the different feel. On 6s the 1518 does remind me of the 1515 with that manic feeling from the midrange on up. My 1518 eventually settled into a 1/8 buggy on 5s geared for 55-60mph. With that setup it lost some of the surge on the top end and felt a little more like the bigger motors and their broader flatter power curves. IMO the 1515 on 5s has more of that manic feeling or surge of power from the midrange on up due to the higher kv. That's my impressions anyway.
Edit: Oh and a piece of advice. If you have any of these don't ever sell them! I wish I would've kept the 1518 and 1520 I had, one of them would be in my 8ight-t right now if I had.

advice taken
Good point about pushing the 1520 and 1717 with taller gearing, they really do like it. I run my 1717 powered XXL geared for 55mph theoretical on 6s, no fan and it just plain pulls hard.

Thanks the Top Kick is about .060" thick . As for the trenchers they are great transformed how the truck runs . I have the stock atx and road rash on the same wheels , these are way lighter so the truck jumps tons better and has better over all grip just wish i had tape them to run on 6s they balloon pretty good . The trenchers are the best hop up i have tried so far .

I run mine on 5s with a 29t pinion, it's a blast for sur!

I have no intention of parting with any of these great motors My 1518 currently sits in my Savage Flux as 1800 kv gives me plenty more gearing/tire options with the Alza center diff, and the 1520 is just about the perfect 1/8 truggy motor.
