Only one at a time. The weight is the same as a shorty that way. Check out

The 28mm outrunners have a 35mm OD, large bearings, and a large kv range, for a reasonable price.

Why wouldn't those batteries work? Parallel they will be able to put out 1250 / 1300 W continuous, and double that amount in bursts. Seems like more than enough for me to handle on only two wheels I know runtime will be limited, but that's fine for me to start out with.

Those are pretty neat motors! I'm considering these options:

• Cobra C-2814/12, Kv=1390: 40 A, 440/600W (3S/4S); yields 41/55 mph (3S/4S nominal) no load wheel speed on 4 inch tires, provided I can fit in the 38/70 gearing as Casper suggested
• Cobra C-2820/8, Kv=1450: 55 A, 610/810W (3S/4S); yields 43/57 mph (3S/4S nominal) no load wheel speed on 4 inch tires @ 38/70 gearing
• Cobra C-2820/12, Kv=970: 40 A, 880W on 6S; yields 57 mph (6S nominal) no load wheel speed on 4 inch tires @ 38/70 gearing; would be able to run this with my 3S packs in series (1400mAh 40-80C ~ max safe continuous current of 56 A)

With 14 poles, all of these are really pushing the max commutation rate of the Mamba Max Pro at the given voltages (that's why I can't run the 1390kv one on 6S for instance); however, under normal load CPMs will be a bit lower and the MMP should be able to handle it.

Main habitat is likely to be some smooth gravel roads, and large smooth grass fields (parks), no hardcore bashing and I am not after setting any street speed records with this one. Any thoughts on the set-ups listed above? Would it be too much power for the rear wheels / tranny to handle?

Edit: the Scorpion HK-2520-1880kv looks very nice too and would not need the maxed out 38/70 gearing, but can only be ran up to 4S with the MMP due to required commutation rate, and then I guess the output would be comparable to the Cobra C-2814/12, but at twice the cost...

I'm trying to figure out tire availability for the 22t...I see that the are 2.2 size but I'm confused because I know that the inside diameter of both sides of tires are the same.

They are not like the Sct truck tires. What should I be looking for in tires as far as sizes that will fit the 22t.

The standard "(stadium) truck" size is 2.2" both on the inside and the outside, so any "truck" tyre will do. A short course truck ("SC") is 2.2" on the outside, but 3.0" on the inside. So just don't get anything with a "3.0" or "SC" on it. Hope this helps.

Thanks...I just see a lot of 2.2 tires and 1/10 scale but I will look for "truck tires"

Put up my super clean 22T in f/s.

Those are short motors (shorter than normal 540 can length) you've chosen. So, they'll be easier on the transmission. Also, I haven't run that gearing combination, but I'm not so sure that 38/70 will fit.

Actually, after a lot (too much) of thinking, I ordered the Cobra 2826/10, like you have, last night. I liked the fact that the 2820's are nice and light, but wasn't sure they would be robust enough for a 1.9 kg truck - I've seen guys do the same with the mini 8ight and although power wise it should work, the smaller motors tended to burn up. On paper, I liked the 1100kv 3548 motors of Hobbyking too; they seem to be great value, but on 6S they are likely to have have too many revs for my MMP to handle and I don't want an air ESC. The 2290kv LBP 3650/6D would be my favorite inrunner, but proved quite hard to find. The 550 cans that were suggested are a bit too heavy for my liking, at almost twice the weight of stock.

Shipping to EU will probably take a few weeks, but I'll report back when I have everything up and running. If the 38/70 gearing Casper suggested is indeed too tall to fit the tranny, I might put some more effort in finding the Leopard, or try if I can make a 62T mini 8ight spur work with some modding.

Maybe it's of any use to anyone stumbling upon here through google, so attached is an overview of the motors I considered in the end. Everything with a question mark is a guestimate from my side, just so you know.

Thanks for all the help ufoDziner! Your set-ups and battery suggestions were very helpfull!

Cool. Have fun with the setup. The Cobra motors are very nice. Btw, it's probably too late now, but the 3548 1100kv is only 10 pole so it easily works with the mmp (I have one and have tested that combo).

I think the motor plate on the 22t is tha same as on the 22. If it is you are in luck and the 38/70 will work. Thats what I run on my 17.5 22

Casper

iTrader: (34)

Yes the motor plate on the 22, 22T and 22SCT are all the same.

Dr_T

Oh, nice! I might get one of these too then, would make a good spare; they're so cheap

Awesome! Thanks for the confirmation guys!

22T Truck Aluminum Part TLR1109

^What front castor do these 22T Aluminum Inline Spindle fit with?

AndrewTom

iTrader: (3)

those should work with all the '1.0' front end parts. options of which include 0*, 3*, 5*, & 10*.
these WILL NOT fit/work correctly: http://www.amainhobbies.com/product_...ster-Block-Set
