Self righting SV27 - it works!

[Stinger9D9]

I got my SV27 back in late 2006 when they were first released and I ran the thing endlessly for months. It spent it's fair amount of time upside down, but a lot of that was my fault (not the greatest driving, just bombing around). Once I ditched nimh packs, the lighter weight of lipos and the Ammo 2300 motor I had put in ensured that it spent more time upside down than right side up.

Also, with my UL-1, surface drive hammer and now my new Motley Crew (which all generally stay prop side down), I had really plenty of other more stable choices so the SV spent a lot of time on the shelf.

I've had a spare SV27 hull I paid $30 for kicking around for about 3 years now and had been meaning to finish it for all that time. I finally got around to touching it up, painting it like my other (the original was just striped up with Mono Kote trim) cutting a big hole in it and putting in a flood chamber made of some thin sheets of fibreglass.

I took it out today for its first run (with just the stock blue SV motor this time out). Here is the result:

This was with a couple pretty lightweight 3200 mah packs. It needs a little help (a bit of torque from gunning the motor does the trick) but other than that, it worked great (it already has a bit of extra weight on the left side, so I don't really want to add more). With heavier 5000mah packs, it may even work better.

Now I can get completely juvenile with it and leave the fishing rod and tennis ball in the car!

sounds okay... Does it handle alright with the extra weight on one side?

How about some pictures of what you did?

Nice job. I've been getting a lot of retrieval time in lately with my superflip. I think I saw a thread somewhere on one of these forums on the how to's of making a flood chamber but I would be very interested in giving it a shot. I have four of these boats.

Hmmm. . . Looks like I found another little project for the sv 27's this winter. There are at least a couple of threads on the how-to's of building a flood chamber.

dood nice work! the supervee must be so much fun without having to worry bout flipping

About ten years ago Rudy Hilado, a member from my old club the Capitol R/Cers, did this with a big gas mono fitted with a clutched Zenoah. He had the tuned pipe exiting out the left front just below the deck line. The transom and rearmost part of the full cowling had holes drilled in specific places to allow it to take on water and roll over clockwise. Was really cool to intentionally toss it in running upside down with the exhaust smoke coming out the of the bow and watch people's faces as it righted itself and took off.

Yeah I know, I've always liked the Supervee but the upside down time was really putting a damper on the fun. I just need to make sure anything that can fly loose when you stuff the hull (like battery packs) are very secure before going out.

I'll post some photos later tonight, for now, I think I'll take it out for some fun.

Hi There;
I have a sv27 also and I would also like to build a flood chamber in mine.Would you know a link for instructions on how to go about it.Mine used to flip quite abit untill I installed twin adjustable trim tabs on the back,along with tear drop turn fins.I have found a big difference in the handling.I would now like a flood chamber,hope you can direct me in the right direction.
Have a great day
