Nope, IMO Titan is just right. When I had mine with a 27 lb turbine I always found it needing more. 34lbs would be perfect. There is a large tank available and you will need it - otherwise you are good to go.

Also, unless the bypass kit Oli was talking about on the RCU thread becomes a reality, it will not be too quick even with a Titan in it. There's a guy back East with a 180 in his and he's still not breaking 200.

Have fun with it, it's a great flying jet!

Thanks! I'm using a couple pneumatic tools as much as possible, but the fuse, especially the main rear section, needs to be done by hand because of all the curves and edges. The polishing tool only has a 3" dia pad, so it still takes some time to get it covered.

Not hijacking the thread at all...this should be about all things scorpion.
From what I've read the extra thrust doesn't rally equate to speed, just noise and fuel consumption. I'd stick with it nonetheless and enjoy it!

Re: Aviation Design - Scorpion

Looks great Sean!!... beautiful paint work!!!

That's crazy that a relatively small jet like the Scorpion with even a P180 in it won't break 200mph ... that's some serious drag there.

I guess going above 140-size starts to make it pretty heavy feeling, eh? With the turbine size and the extra fuel?

Re: Aviation Design - Scorpion

Hey Guys,

I'm the one with the JB180 in mine that I'm guessing puts out about 36-37lbs with a fuelled weight of 34lbs. I have radared it several times and without much of a tail wind the scorpion has always maxed out at 180mph, definitely draggy due to size of inlets and absence of a bypass. The power is fun when it comes to verticals after a slow pass or following a take-off. I use the jettech 4L tank and get over 8 mins using a lot of power. The 140 on the newer, lighter airframe would be a perfect match with a bypass. Mike

Re: Aviation Design - Scorpion

ROTFL!! Sounds like a deal then Peter!! Maybe Altecare can bring in one of the Behotec 300's, LOL

Mike... I bet that Scorpion is a blast to fly in the verticals with that much thrust!! When I had my Elan with Cheetah, that's what I loved the most - punch it in a vertical and it takes off, LOL. Your's would be even better thrust:weight! Do you have any video of your's flying?
