NO, I'm not. It's going to be a bullet. Maybe it breaks in air.

Good luck keeping it together!
Can you carry enough fuel to fly more than 3 minutes? What is your weight without out fuel?

It's a round tank with a flat bottom.
Tight fit installing in fuse opening as it is 3.4 in. wide.
Hope that helps

Are folks using the 50mm of flaps? At 50mm they must be close to 80 degrees down. With a K70 and CG at 110mm, inverted it needs only a bit of down. On landing she only slows down so much and drops like a rock. Drops quite a bit in the turns also.

Does anyone have one of these for sale or know where to purchase kits? I see harlock-rc shows them but not familiar with them.

Harlock-rc.com - Production and Sale of Rc Airplanes

They build them and they are the only place to get them right now, they are made when you order them. They aren't producing dealer stock right now but the good news is, if you do order one you will get it in a couple of weeks like the website says

So has anyone bought a double wall pipe for their viper? I had mine collapse after 50 flights on it. Never ran it with cover off, guess the m70 was too much.

These guys made me a beautiful, well fitting pipe and got it to me in VERY short order. You do have to dremel out a bit of wood for the bell. It also goes in in (2) parts and you then screw the bell to the pipe. It is ever so slightly smaller at the tail so you have to make a few standoffs. It is so much nicer than what ships with the kit.........

Thanks markusvt, I contacted them about making a pipe as they made a beautiful vectored thrust pipe for me. Did it add much wait to the tail end? also is that a 70 or a 45? I'm afraid I'll have to go up one size and the pipe won't fit.

Added very little weight. It came with a sticker on it for the weight, I forget, maybe 100G? I have it with a K70 which they say is good.

So I am finally going to start on putting together my little harlock. I have been looking at the inside and looking a pictures of the little tank it come with the conversion kit. I am thinking of making my own tank that will kind of lock in place around the middle wood rail in the inside. I have a good amount of blue foam left over that i have been packing around haha. I put it to good use. What I am trying to find out is how much does the tank that comes with the conversion kit hold in fuel? and what are your thoughts on the tank? do you wish is was bigger, easy to install and strap down, etc.

The only issue I had with the stock tank is the fittings never sealed right in the neck and I replaced them with BVM stuff from DreamWorks

Other than that, it fits fine and works fine, I don't see any reason to mess with it. I get plenty of flight time with my 45G3 and think carrying any more weight would be of more detriment then benefit. I fly 7m and always have fuel in the bottom of the tank when I land plus the UAT

LOL yeah I can see the 70 just draining the tank fairly fast

Thanks BarracudaHockey. I am just getting tired of getting tanks that you have to end up adding more wood, anchor points just to keep the tanks in place. I will end up making one anyways. I post pics as I work on it.

Radar average upwind/downwind was like 144

Decent but it doesn't have a very large rudder

If the CG isn't back far enough it will tuck the nose in turns.
