Here’s what I’ve found out about getting a lipo pack for my Stryker:<\/p>\n
Compartment will easily fit a pack that measures 4.5″ x 1.34″ x 1.5″ (LxWxH). With some modifications, a longer pack could fit, however the 4.5″ appears to be long enough to fit just about any pack that falls within the other 2 dimensions. The recommended pack from Hobbyzone is a 2200mAh pack that weights 5.6 oz. or 159 grams. I don’t really want to buy the stock pack because it’s only rated for 27A continuous (12C) and it’s pretty pricey. I think there’s a lot of good 15C-20C packs available that are the same price or cheaper. Here’s what I’ve found so far from CheapBatteryPacks.com, Maxamps.com, TowerHobbies.com and Hobby-Lobby.com I mention only these suppliers simply because they are people who I have purchased from in the past and have been happy with the products they provide. I know eBay is full of cheap lipos, but I don’t even want to go there. I’m also only comparing 3S packs, as this is going into a bone-stock F-27C Stryker.<\/p>\n

Thunder Power TP Extreme 2200 3s 01-03-2008: This is pack I ended up getting. I actually bought it for my Brio 10 knowing it would drop right into my Stryker. I have yet to fly it, but it fits perfectly and should provide plenty of juice.<\/p>\n PolyRC 2000mah 3s 30C Lipo (the highest C-rated pack that fits) Maxamps.com has this pack for $63.99:<\/p>\n Lipo 2100HV 3S 11.1V Pack Packs from Tower Hobbies:<\/p>\n FlightPower Evo Lite 2100 3S 11.1V FlightPower Evo 25 2170 3S 11.1V Great Planes ElectriFly Power Series Lithium Polymer 2100mAh Hobby-Lobby.com has these packs (as well as several of the packs already mentioned above):<\/p>\n Thunder Power TP20703 PolyQuest 20 The average price is about $60-$80 with the Vislero pack coming in as the cheapest at only $40 and the PolyRC 30C pack being the most expensive due to its 100A discharge capability. Unless I were planning on upgrading several other components in my Stryker (the ESC is only rated to carry 25A) any one of these packs should be just fine. So I’ll probably just just go with the cheapest. However, I have a $10.00 off coupon from Tower Hobbies, so the FlightPower EVO 2100 looks tempting at only $52.99 after taking into account the coupon. Something tells me it might be a better pack than the Vislero one and it’s only $13 more. I haven’t really read bad things about either pack though, so it may come down to just a money thing. The EVO pack is approved for 2C charge rates and has a higher C rating although it is 8 grams heavier, it weighs exactly the same as the stock Hobbyzone pack so the CG should be spot on with this pack.<\/p>\n Anyway, that’s what I’ve found out so far with respect to a few lipos for the Stryker. I’ll be Sure and post a write-up on what I actually end up buying, until then, I’m still having fun with my 5-minute flight times and that old 8-cell battery pack. Also, I plan on updating this post as I find new\/better packs. Update 01-16-2008: So I ended up buying the Thunder Power eXtreme 2200mAh V2 from Mike over at CheapBatteryPacks.com. I soldered a set of Ultra Deans and dropped it in my Stryker and it fits great, it’s super snug. I added a very small piece of styrofoam to the very front of the battery compartment to keep the battery as far back as possible. I needed to add 1\/2 oz of weight (with some Play-Dough) in the back to get the CG right, and even then it’s still just slightly nose heavy. The Stryker doesn’t seem to care about the extra weight though, it absolutely screams and the run time is great. I’m not sure how long it lasts but it’s at least 10-15 minutes. And the battery comes down just barely warm. It’s a great battery for the Stryker and provides plenty of current without being taxed in the slightest. I’m debating moving up to a 6×5 prop to get a little extra speed. I know the battery can take it, it’s the motor and ESC that will need to be watched. As it is now, the motor is barely warm after a full run, so I think it can take more.<\/p>\n","protected":false},"excerpt":{"rendered":" Here’s what I’ve found out about getting a lipo pack for my Stryker: Compartment will easily fit a pack that measures 4.5″ x 1.34″ x 1.5″ (LxWxH).
