1. Going to try this on mine BJ 42 Great Video today👍 hope the wife is cool about the lipo puffing .

2. AiR Dam . Battery Looks like a loaf of bread. Love the videos

3. Really cool of you to post this. I think you are working on the cure for the inherent issue with this boat, width and too much air being trapped underneath. Looking at these runs there is no porposing at all so you've fixed that by squaring the hull and proper set up. No more warpage. Now it's air management. As you have stated. If you like to tinker, this is the boat for you. It's why I bought it. Anyone can stick batteries in a Zonda and go 100 +. This boat makes you think and your sharing is really appreciated by us who ate less

4. I'm having trouble getting the nose to stay down on my mg36 so I'm going to try that on mine what is the square one measurements it looks like 1/2×1/2

5. What about a wing on the rear putting down force on front ?

6. Good one "B" I just got the BJ 42 it's still in the box no time to unpack. Owning a boat shop conflicts with hobby time and the fact it's been over 105 deg every weekend this summer puts a damper on things. I have been watching videos for the last year on this boat I have wondered if some kind of air dam might help this blow over problem so when I get this boat unboxed I will try something like this on the BJ42. I have had a little problem with the Miss Geico 36 blowing over into the wind but I think that most of the problem with it getting the cg right. Most 6S packs won't fit forward under the deck but I found some Tindling 5200 120c packs on Amazon that fit under the deck and will allow me to move the CG forward a bit. The air dam might be helpful as well. I have got to get some testing time here soon. Hope this heat wave ends soon 45 days over 100 as of today it's tough on a old guy like me. I watch all of your boat videos and love them all. Boat Gang Baby.

7. This is pretty cool. Its got me wondering if taping different foam shapes to the front of the boat to manage air would change anything. I mean compaired to other cats that have a nice sharp leading edge, this one is just flat. There could be a pure symetrical one, one that curves down and flip it around to curve up. Im just getting started with tuning my bj42. Just got the rcbitz goodies and looking forward to getting that mid speed porposing out along with the random blow over. Lovin these vids that show what works and what doesnt.

8. I think you're doing great that's how things got faster in the first place with people experimenting with things that you are doing faster and faster buddy

9. Really interesting experiment Big B, thanks for going to the trouble to test out the idea. Seems to make quite a difference. Looking forward to seeing the next stage of the air dam 😉👍

10. always wondered the cause when a battery goes like that (like a balloon) its also freaky to look at..
