Hypersonic Fly Setup...

Try the following setup and you will be amazed. I call it my Hypersonici Fly


Power Plant: 2409-12T Outrunner from Headsuprc (anchor very well)
ESC: 30 amp with burst to 40 amp
Battery: 1800/25C 3S Lipo
Servos: T-Pro MG90 9G Metal Gear Digital Servo from HobbyPartz.com (must have for additional torque at high speed)
Add stiffners to control linkages or add a control rod guide.
Elevon differential at 35%
Make sure CG is 9-9.25" from nose tip
Prop: GWS HD8060 from max thrust or APC 7x7 for speed.

Hang on to your hats kids, this will be a fantastic ride. I plan to conduct a couple of high speed runs through our timing gate once the weather clears. I'm expect 100+ on high speed dives. BTW the climb out rate is unreal with the 8x6 setup.

Hance, I did the same for a couple of months, but had the need for more speed.

Speed Resutls In...

Will, not exactly what I was hoping for.

10 Passes between 100ft gate (flat run):

1.12 60.88
1.32 51.65
1.28 53.27
1.19 57.30
1.26 54.11
1.30 52.45
1.13 60.34
1.21 56.35
1.22 55.89
1.26 54.11

avg speed: 55.63

Tomorrow I'll try the APC 7x7 prop. Should gain a little more speed.

I was thinking 100 mph that wing would do some serious fluttering and probably start bending and falling apart
I bet at 55 mph it feels like its doing 100 mph I also own a hyperflea and I'm going with 2 cell lipos and its fast enough for me. It will fly straight up and rolls great. Mine does about 35 mph or 40 and believe me I was thinking of putting a bigger battery but to much weight for what I have on hand. Now if I had a lighter 3 cell laying around then I would go for it. But the lightest I have is a 1300 mah thunder power 3 cell and its too heavy.

I run a 3s 1300 on mine it handles it remarkably well. It doesn't throw the cg nearly as much as you think it would.

Add a string/CA stiffner to the wing. Does wonders for making the wing ridged at high speeds.
