Finally got around to work on my Viper
Old school Nmh & 700 Cordite just does not cut it with the BL/Lipo nowadays
Saw all these UL-1's on the scene at our club "HOTMBC" Thought I had a good platform to start my
UL-1 killer :cool2:

After some looking real close when stripping her down I noticed rudder might had been dragging. With straight edge to bottom of hull runs right into rudder where it shouldn't

Good decision to make the jump to brushless/lipo power. You will definately be surprised when you pull the trigger. I am in the process of building up the one in my avitar right now. Set up correctly these boats are very comfortable in the mid 50's. Don't forget to get some video.:thumbup:

HOLY SMOKES

You were not kidding about the difference when pulling the trigger :eek:

I did not run to big a prop so went with a K42 & man !!!
when you say go it GOES :eek:

I am so glad things are going as good as they are. I was reluctant at first to play with the FE stuff but now I am soooo glad I did.
I can not wait to finish sharpening & ballancing some other props for this weekend

I must have tabled it very well because first run I could literally pin the throttle & just steer it around the course
Zero signs of anything bad

Temps after first race esc 103, batts 99 & motor 99
I think I can prop up don't u'al think ?

All the best,

Actually it was not all that loose at all
I was really surprised that it ran very very smooth & tight no dancing at all
I will try to get someone to shoot vid this weekend

I am sooo hooked on FE
especially these smaller boats
pretty cheap for the speed you get

Are you running a turn fin? I don't see one in the pictures.

I find that mine doesn't run loose either, but I have to be very, very careful with the COG. Otherwise a blow-over is certainly in order.
