Proboat Widowmaker first impressions

[iratner]

The trick to stop the hopping is to adjust the strut to just the right angle. And, if you tilt the rudder back a bit, that will help with the wiggle during the turns. See photo.

This turned out to be a great boat! I don't like the "military look", but it will run very fast for 8 minutes on one 4,900 mah 2 cell and not even get warm. What more could you ask for?

Sorry, here is the photo...

It felt like i was out there quite a while longer than 8 minutes, i think i was running for about 15 or so on a 5000mah 2s lipo. I should have timed it more carefully thought because i cant be sure. i also wasnt at max speed the whole time.

Why not buy a $13 prop and balance it yourself. It will only take a couple of hours on the first one, but it will be easier after that and you will be able to save money and enjoy the outcome of your own work.

for the extra 30 bucks id rather just buy one already balanced.

how often will an octura prop need to be replaced? do they get damaged or broken easily ?

doing a little more shopping and am now wondering what the difference is between a 2 and 3 blade prop?

seems the general idea is a 3 blade will accelerate faster than a 2 blade?

[iratner]

I am using a 3 blade from an Aquacraft Miss Vegas and I am getting great acceleration and smooth ride at the top end.

Finally, I took a photo of the photo using my phone. Notice the strut angle and the 3 blade prop.

cool. i made a small order today at tower so i put a grim racer metal prop and a couple of the miss vegas 2 blade props on it to test some things out and see what works. once it is back in the water i'll start making adjustments.

thanks guys.

Ira is using a octura Y535/3 prop.

[AxlesOfEvil]

i picked up a couple of y535/2 props in plastic/fiber to see how they work.

can anyone tell me the difference between a 2 and 3 plade prop ? it seems like the 3 is more for acceleration and less top speed?

well yesterday i took the boat out again and the prop works GREAT...

however, it is even bouncier now, one time it slapped the water so hard the lid popped off. luckily some "real" rc boaters with their big gas powered monsters were there with a retrieval boat to get it.

i had the strut angled all the way down to see what would happen. BAD idea for any kind of even mildy choppy water. the big gassers were skimming across the water like it was glass but mine was poppin and diving all over the joint.

they told me i should move the strut to be about level with the bottom of the hull.

if i cant get it trimmed out with the strut, im going to add some trim tabs for a supervee to it.

[knahinu]

Use a ruler or a straight edge and get the strut level as possible. If that don't work, try tilting the rear of the strut up, alittle makes a big difference.

[AxlesOfEvil]

i tested it out a little bit today in my gf's pool lol. not enough room to get it going, but i think i am getting somewhere.

thats a great idea with the ruler to get strut level, i'll have to try that.

at first i was skeptical about boating but man im hooked now. i cant wait to get another one. im thinking a catamaran would be sick.

any videos?

I put mine in the pond yesterday, run it for about 2 minutes and it stopped dead in the water, I went and retrieved it to find the battery exploded and fried the esc. The battery was a brand new venom 3200 7.4 lipo, I have cycled at least 3 times, never ran the battery for more than about 5-6 minutes, always leave switch on lipo for the esc, the battery has been charged and cells balanced with venom pro charger. I don't know if the battery failed causing the esc to burn up or if the esc caused the problem. I haven't contacted proboat yet, but this sucks.

3200mah may have ran down under a safe volt ?
