Well they did in fact ship the wrong batteries, they have shipped the right ones which will arrive next week. I picked up one locally just so I can try it out on the weekend.... I am guessing since I can't change out the esc, running 2 11.1v 1000mah in parallel is out of the question also? I was just looking to extend the run time but that may not be the best idea?

Okay now I am kind of confused.... I was talking to the boat guy at a local hobby store... he runs a minimono.... the confusing part is that the mini has a 20 amp esc and a 28-30 motor, both smaller than the GP-1 but yet the battery rating is 1000 to 1600 mah? What is the difference? Prop size?Comment

Ok so took the boat out twice, both times it tried to dive like a sub... multiple times... tried punch launch from stop... it dived... tried moving battery back as far as possible. ... it dives.... so far, this has not been a good experience. ... anyone have suggestions please....Comment

Is the strut adjustable on these? If so, can you raise it to help plant the transom and kep the nose up? Did you try launching by tossing it in the water with some throttle?Comment

Yes it is adjustable though I have not touched it yet. I did try a few tosses but they ended without success. Aquacraft and Tombsy (member on RC SParks) have both told me this is a normal behaviour for a hydroplane. You are supposed to let it submerge then when it bobs back up hit the throttle. I have yet to try this, but I will on the weekend. I am hoping to make a few improvements as suggested by Grim so we will see what happens. I was going to buy the 2600kv motor but I want to see if I can get the hull on top of the water instead of underneath. If I can do that then I will concider the motor, if not, that money can go to a mono which I am pretty sure I can keep above the water.....Comment

air traps.jpg
Built some airtraps... they didn't have 3/16th so I had to go to 1/4 figured its better to be 1/16th deeper than 1/16th short....Comment

I also am having this problem with boat not getting up on plane....I'm going to build air traps, and do all the other suggested mods, and will report. This thing is pretty fast in stock form. Once I can get it handling well, I'll probably go ahead and upgrade the motor. FUN BOAT!Originally posted by Gage_AB View PostComment

Just be very careful with the glue, it is like super glue... very good chance to glue yourself, if you get some on your finger, just don't touch anything, it will peel off the next day. Not that I did that :) As far as getting on plane, I wrote Aquacraft, their response below....
It's normal to toss a boat into the water at full throttle with a flat level motion to get it on plane. If you toss it, the boat should get on plane quickly. In the water, what you see is normal, the boat may require you to wiggle the rudder or release the throttle as it submerges and then quickly apply full throttle to get the boat on plane.Comment

Air traps further info....
I made mine 9 inches per side, trimmed back 1 inch on the first one then traced the same curve on the second with a pen so they would be close to the same. I also filed the edge that is running in the water from outside to inside with a nail file from nail clippers... it doesn't take much pressure, also filed the back curve part to take off the rough edge from cutting. When you go to put them on the boat, fit them first, I found I needed to cut about 1/16th off the end tab. Once in place with the glue, I smoothed them down with a screw driver, you only have about 30 seconds before the glue starts setting up so be sure of your placement before you apply the glue. I ran a bead of glue down one side about 1/8 inch wide. Place the air trap then wait about 5 minutes before you do the second one so that the first is firmly set.Comment

So you know.. Airtraps have nothing to do with getting the boat on plane but at speed they do work well to stabilize the boat.
Prop is EVERYTHING when it comes to getting the boat on plane..

Thanks Grim, I kind of figured that but good to have it confirmed. Is there a better prop choice than stock to help a beginner like me get on plane easier? or any thing else I can do? You make it look so easy in your vid....
I have a Octra 430 prop but it is not sharpened or balanced, would this be a good option if I put in the time or maybe there is something better?Last edited by Gage_AB; 08-26-2014, 02:15 PM.Comment

Just a quick note to share.......I too had the non plane issue, I found going deeper in the prop depth helped a lot, I then slowly found the sweet spot, but in stock form about 2 or 3 mm below being flush with the top of the mount got the boat running just fine.Comment
