On another tunnel thread the subject of 6S equipment came up and I think it merits a stand alone discussion. I have been testing several combinations with 30-36 inch hulls that were converted from .45 nitro hulls. The information I am posting here is from my on the water experience. I am looking forward to actually racing heats in Charleston in two weeks at the World Tunnel Champs. Should be some good knowledge there and 4 dedicated FE classes.
First point is the lower unit. I like the K&B or Lawless .45 size lowers with Hyperformance adapters. Simple bolt on availiable equipment.
For ESC's I have used T-180, Swordfish 200-220-240-300 amp units and Castle 240 plain and Ice.
For motors I have run everything from 4074-4082 Leapards 1515-1520-1521 Castle and Neu, plus a Scorpion 4020 outrunner. 1250 to 1900 KV's.
If you are converting a .45 size nitro hull I would recommend a Leopard 4074/1400 or 4082/1250kv for economy and a Neu 1515 1.5Y 1500kv or Neu 1521 1Y 1600kv if you want a bit more quality. The higher KV and watt motors can be run on 5S to start with to get proper setup on the boat. A 1520/1600kv with an m445 on a good hull is capable of 55-60mph in heat race trim and mid 60's with an aggressive prop. Bottom line is there is more HP here than these boats can handle. Finding a larger hull and more hp will just create a new set of problems. If an honest 50-65mph isn't enough go for it.
For ESC my favorite is a SF200 for price and it has data logging. You can toast it with a 1520 motor and aggressive props. I like it because it is compact and narrow and fits in radio boxes easily. From there a SF240 or Castle 240 Ice will give you all you need. The SF 240 is larger. Another good choice is a T-180 but I have had difficulty fitting them in boxes with cooling lines.
I am taking a 1250 Leopard / SF200 to run Q class at the worlds and my son's Q tunnel in open class will be a 1520/1600 Castle with a SF240. 2 3s 6000ma in series on the 1250 and 2 6S 4000ma parallel for the 1600. These will cover 6+ laps and come in at 3.7-3.8v per cell.
I you have a Q OB lets hear what you have and if you have questions this thread is open for business and I hope others will share their successful setups.
