Maiden Runs - Insane FE30 & Insane Mono 34

[rickwess]

Opened up the cottage this weekend so it was time to test out the fruits of my labour over the winter. The weather was not kind though........lots of rain. I couldn't wait any longer so I went out any way. No vidoes, I had a hard enough time keeping things dry.

Insane FE 30

DSC_0038.jpg

• TP4050 2220kv
• SF 220+
• 4s1p 70C 5000mah
• m445 (S&B by Dasboata)
• strut set as close to vertical as I could make it

All I can say is "holy sh!t" is it fast. No issues getting the sponsons on the water at all. No hoping either. Just smooth and fast. I'm used to a 45mph Revolt and this thing was significantly faster. My guess is mid 50's with the m445. Everything came back in cool after the first minute and again after running it another 2 minutes.

The only issue was quite a bit of water getting into the boat. I'm sure it from from a less then stellar tape job in the rain and the initial flood of water over the sponsons & bow when it's put in the water and you get on the throttle. For the second run I stuffed a couple of paper towels by the leading edge of the hatch and did a much better job at taping. The paper towels were only slightly wet when I removed the hatch.


Insane Mono 34

• TP4060 2040kv
• SF 220+
• 4s2p 45C 4400mah
• x447/3 (detongued and S&B by Dasboata)
• stinger and trim tabs set to neutral
  

Not as much luck out of the gate with this. Lots of cavitation before it gets on plane, very smooth at half throttle and it starts to porpoise bad at full throttle. I couldn't hold it a full throttle for more than few seconds for fear of it bouncing right of the water and into a butt ugly stuff. From the few seconds of full throttle, I could tell is was fast though. At least 50mph and everything was cool to the touch when I opened it up. That surprised me as I was half throttle for most of the time.

I'm not worried about the cavitation. I know the x447/3 was a little small for the weight of the boat. The porpoising is concerning. It think it tells me the stinger is trimmed too far up and I need to push down a little..........at least that what I would do with my full size boat. I'd rather not do anything with the trim tabs yet. Does that make sense?

Man we need some videos!

2nd run of the FE 30. I changed the prop to a m545 this time. As you can hear, my Lab is up to her usual freak out at the boat. I think it's running good, but it is my first hydro and my 2nd build. Suggestions would be appreciated.

My first ever build, the Mono 34 didn't fare as well. I adjusted the stinger down a couple a degrees, but it was still as loose as can be. I had the most amazing stuff after 2 cartwheels. As a testament to how well it was built, there was no damage. I thought my videographer was taping the run, but nothing was on my phone. Too bad, it would have placed well in a worst crashes competition.

The CoG is set at 9.5". Any suggestions on how to tighten it up would be appreciated. I think I'n pretty much at the adjustment limit of the stinger so I'm think trim tabs now.

You know, I tried for one heck of a long time not to put any trim tab into my 35" DF. Thinking that I should be able to get her going without the added drag of the tabs. Thought COG should handle it. I raised my stinger up from the bottom of the hull and that settled the loose chine walkin' but only when I finally broke down and tweaked the tabs(not much mind you) did it ride straight and true. I think this was still when it was loose before the stinger mod. It was as good as I got it on CG alone but on occasion... wait till the end.

Mmm, I don't have any vid of the improvement.

By raising the stinger, do you mean the angle or drilling new holes higher up on the transom?

I would try the tabs first Rick. Because yes I mean drill new holes.

[rickwess]

Thanks again. For sure I'll try the trim tabs first.

I don't think you need to go any higher on the strut. Especially with the shorter stinger. Make sure the strut is neutral and make your tab adjustments no more than 1/4 turn at a time. You might want to start with the tabs up a half turn since they are mounted pretty close to the bottom. I actually had a mono once that was acting funny and I had to raise the tabs to settle the boat down.

[Doug Smock]

Have you checked the bottom of the boat?

[rickwess]

Thanks for the inputs guys. I'll set the stinger back to neutral and play with the tabs to see if I can settle down the hull.

When I originally was setting neutral on the stinger and tabs, I did notice that there was a high spot on the bottom (1-2mm) about 3cm in front of the transom. I know someone on there ended up having to blue print the bottom of a IB34. I'd hate to mess up a great gelcoat as an experiment, but it may be what I have to do if adjusting the trim tabs doesn't work well enough.

You'll never get the boat to run properly with a rocker in it. It's not something you can tune around.
Blueprint the bottom and you'll be surprised what a difference it makes right off of the bench.

I'm travelling for work and the boat is at the cottage. I'll post pics of the high spot. Is blue printing simply filling in the lows and sanding the highs?

[Doug Smock]

Yes sir.
You may get rid of the rocker (high spot) just by block sanding the bottom.
I've seen boats that had enough gel coat on them that I didn't have to add filler.

Work slowly so that you don't sand through to the glass.

Pics will help.

[rickwess]

I'll post some pics with a straight edge as reference when I get back up to the cottage. Travelling for work and Mother's Day will delay me being able to do that.

I took a good look at the mono this weekend. The good news is that there are no rockers in the hull. The trims tabs are pretty much flush with the bottom of the hull so I think i'll elongate the transom holes and raise them so they are 1-2mm above the bottom.

The bad news, if you want to call it that, is that I spent the weekend prepping the J-Craft for the season. Nothing technical, just lots of polishing and waxing. I just love the DI two-strokes. After 6 months of sitting full of fogging oil, a simple turn of the key fires it back up.
