LiPo's I need HELP.

[TimXLB]

Hi everyone,

I am going to be going brushless this summer in the dirt.
I also am going to be running LiPo's.
what should I buy?????

Orion 4800's (so far the only LiPo I have ever used)
Orion 3200's (I have seen these run in the Mini's at our track)

I have heard of ApoGee (sp??) but I have never seen them.

I will be racing off road Novak 13.5's and 4300's in a B4 and T4. I might be getting a Yokomo 4WD too soo I will need saddle packs. )this will be a 5.5

all will be powered by GTB's (club rules I don't run LRP, Tekin's just shut off)
they will not allow anything not R.O.A.R. approved.

any help would be great!!!!!!!!

Thanks

Tim

Get the trakpowers. They are 114-120 bucks and 4900mAH plus they deliver 7V on a 100A load.

More bang for the buck and a top-notch quality

I'll second the trakpowers. They are made by flightpower and those are top notch packs. Don't let the fact that the Orions have Kokam cells in them fool you. The cells in the Orion packs are NOT the same cells that Kokam uses in their 4800 4S packs. The Orion 4800 is only a 15C pack and is a 2S2P config., although the smaller capacity pack that they sell is a 20C pack.

I'm not very familiar with the Novak setup that you are running, but if it isn't too hot, you could consider the maxamps packs. The 2S2P 8000mAh pack is nice for the price. On the other hand, the trakpower comes encased in that plastic. That's definitely a plus. I've lost enough $200 or so packs to crash damage to be able to appreciate the protection that the case gives.

the novak setups he is running for the b4 and t4 are 27t and 19t equivalent. You wont be pulling that many amps since they are very mild setups. Any of the packs mentioned would be fine. I would check with the track first to see if they are limiting you to a certain mah or anything since they are controlling the esc and motors you can use.

Hi,

LiPo's are new this year at our off road track. we did run some indoors on carpet in sedans with foam tires just to see how they would run against the 4200's. the only packs that were there were the Orion 4800's. they lacked the punch the the 4200's have but made up for it on the back end of the runs.
I ran a friends 4800 in my X Ray 007 and found it to be different than the 3800's and 4200's. I did miss the punch but run times were the same at the end of run as they were at the start.
outdoors I think the track will lat you run any LiPo as long as it's close to the 4200's. the owners have bought Orion 4800's and there is 5 other people with them too.
one has the ApoGee LiMn packs but I have yet to see them run.
I have 3 weeks to get everything I need together chargers, LiPo's balancers and whever else I need.
(well two GTB's too).

Thanks

Trakpower should give you more punch than the orions. They have a lower voltage drop under load.

Not just the Orions...The Trakpowers have been tested to have higher voltage under load than the IB4200's...not to mention the fact that they weigh about 5oz less too.

Hi,

thats what I'm wondering. where am I going to put the extra 50 oz on my B4/T4. I already have 2 oz on the back of the B4 just to get it to hook up. the T4 works good right now.
both have GT7's in them so I'm hoping the GTB's will add a little more weight. I have to make Min. weight for every round and the mains. they are really picky about this.

Thanks

What I would try is to get some of the stick on inside wheel weights for cars where you can cut off sections to stick in various areas on the chassis. If you have a lot of traction on the track, you might have to add some weight up front, or you'll end up with it running like my T3 when I blip the throttle:

Hi,

Wow. none of the brushless do that at our offroad track. some do at our stadium track but they are running 3.5's with foam tires on carpet.
what do you have in there?????
and now I am looking for some saddle packs as well I'm going to run 4WD again.... the last time I ran 4WD the Yokomo Dog Fighter was the only 4WD car you could buy.
2 shocks laid down between the suspension arms, chain drive, ball diffs that you rebuilt every round and a RC10 style slipper (I put it on after the first pack... first of many, many mods to it)
this should be fun!!!!!!!!!

Thanks

Do you have any plans in buying a new 4wd buggy, Tim?

[TimXLB]

Captain Harlock:

Hi,

Yes I do. I have been looking at the BJ4WE. the new Yokomo buggy and I just read about Tamiya 501. the down side to the Yokomo and the Tamiya is parts...the lack of. the BJ4 is looking the best right now....if I can find a new one somewhere.

Thanks

I'm running a Mamba Max ESC, Feigao 380C 6L motor (4817kv) and a Trakpower 2S 4900mAH Lipo. It's been GPS'ed at 47.7mph, which is way too fast for most offroad racing, but it's a lot of fun to bash with.

[captain harlock]

You should keep an eye on the Hot Bodies Cyclone D4 Buggy, too.

It seems to be the best around.

Hi,

Thanks for the tip. I have yet to see this one. I'll do some surfing a little later today.

Thanks
