lincpimp · **Possible Ext Crt.5 Setup -** 01.03.2008, 10:37 PM

Ok, got a used crt.5 for a good deal (thanks starscream) and was wondering what to put in it. I have a random selection of equipment here and wanted to throw something together for it.

I have a hacker c50 15l (1624kv) a kontronik jazz 40/10/24, and a pair of 2100 3s 20c lipos. Figured that I could run the hacker on 6s lipo and gear for about 40mph.

My question is do you think that this setup will draw around 40 amps, or more? My basis for this is my LS10 that runs a hacker 13l thru a quark 65 and a 3000 mah 20c 5s lipo. The 3000 lipo says cool and has good runtimes with that truck, which is similar to the ext crt.5 in size and weight.

I do not think that the LS10 setup is pulling much more than 50 amps, cause the 3000 cells are not true 20c cells IMO. So figuring 50 amps at 18.5 would give me about 925 watts. The proposed crt.5 setup would have 40amps at 22.2v, so about 888. The crt.5 will be geared lower (by a few mph) and should be slightly lighter than the ls10. Battery weight is 370g on the ls10 and 330g on the crt.5. The lower kv motor should draw less, just not sure how much less.

I guess since I have all of the equipment that I should give it a try and see what happens!
