It flies better in the turns with a rearward cg as well. If I can recall, the rearward cg also helped with the flap trim issue as well.

Is the split tank the largest that is offered? I seem to recall there was something larger available ?

Bruce, as far as grass fod, you will have a problem. I plugged a fod screen on mine and never got it off the ground. I ended up building some balsa covers over the wheel wells which solved the problem. I think you would like this jet and it handles well.

Thanks Paul, its feeling more comfortable, but I'm still thinking a little nose heavy. I'm working with Gary on a pair of smaller smoke tanks that I'm going to put back on top of the turbine rails. They will be about 20oz each. Then I'll plumb my split tank in series for only kero to give me 4L capacity. Should extend flight time nicely.

Re: Aviation Design - Scorpion

Did a little plumbing today. Cleaned out the partitioned smoke tanks and plumbed it in series with the kero side to give me 4L of kero.



This evening my two smaller smoke tanks arrived. I just placed them in to check sizing and will plumb and secure them tomorrow. They hold just over a liter of smoke oil.

Re: Aviation Design - Scorpion

Hey Cy! Not sure quite yet! I have a SM Viperjet with JC Cheetah that I hope to maiden later this week and was hoping we could get Peter's Scorpion out also! I'll keep you in the loop!

Trev,
I did get a couple flights on the Scorpion at KJ, not sure if there are pics and video. I'm not as comfortable with it as I am the Futura so at a large event I flew the Futura a lot more. I'll get more flights later this month (heat wave here right now) and aim to post some video. The fuel and smoke setup did work without any issues so I was happy about that.

This is how its done on my Futura and simplifies assembly a great deal. I have a larger washer than what is shown here.
How did you do the blind nut/ply plate install in the wing? Would you have any pictures of it? My wing panel doesn't fit tight to the root, there is a gap at the leading edge. A wing bolt on the root would close up the poor fit.
