Project Red Evo

[Graeme]

I just received a Red Evo hydro from HK. I took it out for a test and I am impressed with how stable it is but not overly impressed with the speed. I would guess maybe 25 mph max. It came with a 32 mm 1.4 prop not the advertised 36mm 1.4.
Any way I sold my surge flusher but happen to have a Turnigy Typhoon 500H Heli Motor 1800kv left over.
So I am going to build the Red Evo with the outrunner and 6s lipo.
should produce some decent speed.
going to have to reinforce the hull and upgrade the shaft.
will add some pictures soon.

I do have one question though would a 120a esc be enough or should I go bigger ?

6s on that size hull is stupid, 4s would be the maximum that you should run on that size hull.

The motor you have would be ideal.

If you' ve got good batterie 3S 5000mAh first try other props and after upgrade the motor, TYPHOON or Leopard.

I like this hull

The 120a is MORE than enough..........a 90a would be fine. 4s is plenty as well............i would suggest a 380 28x58 or 28x68 in the 1900-2200kv range.

i agree 60 amp is ul1 power kicck azz in that hull it came with a 28 class motor right?

It comes stock with a 28x48 2636kv motor..............

This would be an upgrade in power on 4s: http://www.hobbycity.com/hobbyking/s...hless_Inrunner

or a Feigao 380 12xl (28x67)at 2076kv...................

sounds good 6s sounds kinda heavy for a small hull

So far I have installed a 90amp esc that I had left over from the surge crusher and reinforced the back of the boat where the rudder and strut mount as it was very thin.
After taking it out for one run I noticed a hair line crack in the paint. Also there was a little more flex where the rudder mounts then i liked.
so a few layers on thin fiberglass it stiffened right up.
next I am going to try a few different props while waiting for drive line parts.

Any suggestions on driveshaft and hanger ?
I want to stick with 4mm as that is what is in my other boats.
