NEW Pro Boat Impluse 31 RTR V2

[Filmgaffer]

Hey guy's... And Gal's.
I just signed up, as I have been reading your posts, but unable to view any pictures of what was being discussed. I have a 2012 Stiletto and was looking for a fast deep v. Impulse 31 v2 really caught my eye as it looks the best out of the current runners. The upgraded esc and dynamic motor was a plus from the original version. I bought one yesterday and got a chance to work on it today. Changed the connectors to deans ultra plug, gonna run 2 x 11.1v (3s) onkyo 5000 x 35c. Lubed the shaft, Centered the balance point 9". Installed that pain of an antena. ( gonna switch the grommet for a hard mount anodized antena receiver hop up). Need silicone just to have it stand up. Anyways.
Haven't run it yet. Maybe Thursday if not too windy. Look forward to seeing what the boat does with the batteries all the way up front.
Ps. The steering servo wood bracket was ok on this one but I caught the antena for the dx2e was broke out of box at store. Switched immediately. Hobby hobby. Great store. Mississauga Ontario Canada Eh...
Will post results when I can.
Thanks for the things to look for when buying this boat. It has helped.
Cheers.

Does Anyone have any to say about the dual rudder kit available from horizon hobby for the Impulse 31 v2.
Worth it or not. And why?

I wouldn't, unless you are putting in a substantially more powerful power system... It corners great, but does double the rudder drag.

Bought one a few weeks ago

i use 5 s 4000 mah 40c ( i think 6s is to much for a 1800kv motor,just my opinion)

changed the prop to a graupner 40 mm 1.4 p
changed the esc to a 120a seaking ( stock one is very heavy)
still have to change the 4 mm lipo connectors to 5.5 mm because that's the only thing that is getting hot ( besides the lipo's)

so far : i like it , worth the money

Well I ran my new impulse 31 v2 today. Put 6s in and gave her a few rips. Bouncing like crazy out of the box basically. Brought it in and lifted the trim tabs 1/8" from bottom of hull as noted by another member and bent them down even with bottom of hull. Lowered drive shaft prop by 1/8th" and its glued to the water. 6s is fast for a short 15 seconds at a time but 4s is fun all day long.

Can someone explain why? Impulse31 v2, is faster with the engine PRB 3310 A3630-1500kv (Old Miss GEICO), which, A3630-1800KV DYNM 3830. com The Same settings

Could be the Dynamite 80amp ESC that is in the new Impulse31. The motor is the Dynamite 1800kv.
By the way. 3rd run out on 6s I twisted the flex shaft in half. Make sure you have spares before you go anywhere.

hi, filmgaffer
I use flex shaft miss geico
I run only 5s (46-49mph) good speed for me and for my boat

Sorry your saying the 1500kv motor is faster than the 1800kv?

[Filmgaffer]

Now that I have it dialed in It corners great just as it is.

[mannytx1]

YES, 1500kv motor is faster than the 1800kv (no quality dynm motor, or no torque)

[Filmgaffer]

It could be a difference in the winding. 18 turn say as opposed to 22 turns on the 1800. Just a thought. 18 and 22 are just as an example not actual specs. Hard to find specs.

[Filmgaffer]

Specs from horizon say 1000-1999kv. Wow.

[mannytx1]

Horizon for something hiding the specifications of all products (Chinese toys)
