Bow wave suppression

Hi Floating Voter,

I do so agree that I should be flying, not ploughing. in fact, she does plane quite well, but she is 'dirty' at very high speeds.I am concerned that sooner or later, I will have electrical problems, despite trying to be careful not to overuse the throttle.

She is fitted with 2 x JP EnErG brushless 600 O/R 1550 (C35 141), driving 38mm scale-type brass three bladers, contra-rotating. The pack is a 7.4 v, 30C lipo.

That is quite a good idea, right out of left field. Thanks, I will look into it.

i know that it is out of period but a front hydrofoil would lift the bow at speed.

Aren't you supposed to be riding over that bow wave not wallowing in it? if you have Lipo batteries you probably have brushless motors (kV? how many cells?) - try a smaller prop - much smaller - let the motors run free and show what they are capable of.

She's already low, so I am loathed to try this. and no this is not wunwinglo from large scale planes. I do small scale planes!

Hi WWL, Hmmm! Can you perhaps squash in some bigger / heavier batts to lever the bow up?
Young at heart 😉 Slightly older in other places.😊 Cheers Doug

Is this the wunwinglo from Large Scale Planes?
If so, welcome to the other side.

Hi "He who needs more lift under wunwing"😁
What batteries are you using?
And where are they mounted?
Cheers, Doug 😎

Hi Canabus,

I cannot really do this as she is slightly heavy. I was aware of this when I restored her last year and was careful to keep it light and aft. She is lighter than she was.

Hi wunwinglo
Try moving weight in the boat to the stern to let the bow come up at high speed.

Bow wave suppression

Guys, my MTB has a tendency to get a little flooded by her bow wave when under way at high speeds. She has a scale spray suppression rail at the bow which is notched like the full-size. I do not want to mount anything TOO gross but do any of you have some practical suggestions to make to alieviate this problem?
