Brushless CRT Questions

I only have #'s for a TP pack...and the results were so bad I question the data all together. Couldn't even hold 12C bursts. But a cross check with a GP3300 pack held strong and suggests the eagletree was valid. Seems a thread on eagletree data would be of use to us all, since the batt companies won't play by a standard set of rules, and unlike others here I don't have the funds to buy so many Lipo packs at the 5S level. Think there's enough #'s amongst us to make it worth while?

It might also be a good idea to list which companies are using the same cells. How many producers are there of lipo cells? Not the actual battery, but the cell that the battery company buys and puts together. Did that make any sense?

It would be nice. Saw once on the net somewhere. But I think by now it'd be outdated since some companies are swapping sources regularly it seems. I'll see what I can dig up.

Ok guys, I just got my CRT rolling chassis in the mail yesterday so it's go time. But before I start ordering some things I have a couple other questions that I need your help with.

Here's an update . . . I've decided that I'll go with the Neu 1515 instead of the Lehner now - given the latest info on the MM software updates due out very soon to handle the cogging. I will be running two 2s 4900 Trakpowers together for a 4s 4900. Here's my question: which KV Neu 1515 should I get, and what pinion should I put on it with the CRT stock gearing?

As you might remember from the begining, I would like to hit a top speed of 45 mph and run very cool. It gets in the high 90's and low 100's in the summer here.

Thanks guys!!!

Well I have finally got my CRT going and may have some advice for you.:032:

I went with the Neu 1515 2200kv motor and it is awsome the Mamba Max esc works great but has a cogging problem with the Neu motor there is an update coming out soon I hope? I'm debating on spending the money on a Quark 125B or just wait for the Mamba Monster Max ESC?

Spurs? The stock steel spur will eat your pinions up in no time change your spur out to the Kyosho 46T nylon spur and the pinions will last alot longer.

Pinions? I found the best deal on 5mm pinions at tower hobbies in the Heli parts section used on large scale electric choppers.

Mounting the motor is easy in the CRT I found a peice of 1/4" aluminum in the garage that worked great I drilled and sloted it for the motor and bolted it to the diff mounts in the brake pad holes and 4 bolts up from the bottom of the chassis. :027:

Nice work IBJAMMIN!

How are your batteries mounted to the chassis? Double sided stick tape or what?

Very nice CRT IBJAMMIN. What battery are you running in that rc18 if I may ask?

Excuse my ignorance, what pitch are those Century Motor Gear 5mm 1.0 Module pinions...can't find any detail on Tower's site. Are they the same as is used in typical monster trucks...like the Emaxx?

25.4 pitch.

Ahhh...so 1/8th buggy stuff is quite different from truck...which I think is standard 44. Thanks.

no, most of the buggies truggies and trucks use a MOD1 as spur.
