Show Your UL-1 Setup And Speed

I have made several successful runs (5) ranging from 49-51 MPH on the data logger, the turn fin was on. I got about 5 minutes on each run, used a M445 B/S and two 11.1 2600 ma lipos. The boat did not flame out and handled like it was on rails.

Can you post the eagle tree FDR file so I can check it out?

49-51mph on 22.2v ?
Shoudn't that be 14.8v?

Voltage

Two 11.1 Lipos with stock harness equals 22.2 volts. I think I can get another 5mph by removing the turn fin this will require the addition of an air dam and some weight adjustments to keep the front of the boat down. By doing this, the boat handling will be seriously compromised, this type of setup would be for straight line runs only.

Your only getting 49-51mph on 6s ?

Some are getting that on 4s .

sounds like something is wrong here, going from 4s to 6s is a 50% jump in volts, like a 50% jump in speed!

I tried the X440/3 today and it ran almost 5 mph slower. GPS was 39.4 mph and the lipos ran hot. I had 44.2 with the a detongued X445 and temps were much better. It was fastest with a detongued back cut Prather 225s but I didn't get a GPS reading yet for that prop.
