What's the best use for a Razor 2500? Gride or G-480

I have a Gride coming for Chirstmas (already bought) but I just picked up a Razor 2500 and didn't know if that would be an overkill for the Gride or if the G-480 would be the plane to go with.

I would like both...but I also have a Park Cap from www.Stevensaero.com that I'm building too. I like the idea of the larger G-480 but didn't know if it was too big for the 2500.

The other option is to build the G-ride with a Razor 400 or 300 that I have (the cap gets the other) and then save the Razor 2500 for the Ultimate when if it ever gets here (please, please, please, please, please, please, please....). Again, would the 2500 be enough motor for the Ultimate? I'm not into hovering but want good vertical pulls.

My current battery selection is 1100 NiMH's that can deliver upto 20 amps and two packs of Kokam Li-po. A 2s1p - 1500 and another 3s2p - 3000 so I think I have my bases covered for the any battery situation.

Thanks again ezone!

I have a Razor 400 in a GWS C gearbox in my g-ride. I use a 10x8 prop currently. It has gobs of power. I have known another guy genovia that flew his g-ride with the 2500A, but I think its just too much. Most of the time I fly my g-ride at 50% throttle with the RZ400

Here is a video of mine flying with that setup

Kevin,
Is it a 2500a? (i.e. geared?). Bill designed the Groove to be compatible with the 2500a and Hacker B20 series, (as well as others). If does not support the GWS stick mount (which is how you'd probably gear the straight 2500).

That said the 2500a is perfect for the Groove. I fly my Groove with a Hacker b20. I also fly my G-Ride with a Hacker. I however would reccomend the smaller Razor 300-400 series for the G-ride as it helps keep the wing loading down and allows a much tamer flying style. To me the Hacker or 2500a is overkill for the G-ride.

It's just a straight 2500 motor (although I will upgrade to the gearbox when I'm ready to use it). Looks like I will wait for the Ultimate and get the gearbox then and use the 2500 for it.

Thanks again for your help and insight Scott.

I just got the gearbox for the Razors from Bill at Park Flyer Motors and bolted it to my RZ300. The spacer/adapter for the gearbox bolts right on and you don't have to cut the shaft. I was surprised, I thought that I would have to. I am also waiting for the Ultimate, I have a B20 15L geared waiting... But I could also get the Groove for the same equipment... Now I have to try to hold off...
