have seen the speed wing... just didn't put two and two together I guess. Do you feel his wing design is faster?
Faster that your typical FT wing.

Holy thats one hell of a motor. What kind is it?2845 2750kv motor that can take 6s
Man, you're right - that's insane!! I have a 2207 2500kv that can take 6s, but a 2845 should be able to spin a bigger prop and be way faster.Holy thats one hell of a motor. What kind is it?
That's what I thought. Because it is out of an EDF which really only spin comparatively small fans compared to larger props it makes sense. I would say you would need a serious ESC to handle the loads. Do some bench testing to see how it fairs.it's out of an edf, so I don't know if I'll trust it with a big prop straight away. It's branded as a Predator, but aside from that I don't know much
What motor is on it currently? My guess is that you'll have a lot more thrust but less top speed.Now I am thinking about putting EMAX 4030 on it (I am guessing this is about same as FT Monster motor). 6S 4000 70c and a 16x10. Battery will barely fit, motor mount will just fit on the nose. Not sure that I can get this to balance... maybe move the wing a little more forward.
Am I crazy thinking this would work?
foam thickness 6 or 3 mm? I want to build this plane wingspan 60 cm, with motor 1806 2300kv and small battery 4S. In this size, will he be able to fly at a speed of 120-150 kmh?
I just build this plane and I'm noticing two tendencies when I fly it:
#1 It torque rolls
#2 Tends to nose up.
MY power setup is:
EMAX 2205 2300kv motor
APC 5x5 electric prop
850 mah 4S battery
I was wondering if anyone else had these problems? The plane nosing up seems to happen when I give it some throttle and I noticed that there is no thrust angle on this plane. Did any of you experiment with adding some downward thrust? Would a few degrees of downward thrust fix this? The torque roll is less noticable and it seems to go away at higher speeds, but even at higher speeds I still have to apply a little bit of right aileron roll.
Sorry I haven't been in here in a while...been a couple years since I've flown a foamboard airplane to be honest. That said, I still sell a kit for the Deamon now and then. Seems that it's still a relevant airplane.
I'm going to go out on a limb and assume that your plane is a bit tail heavy, given the use of a pretty small motor. The CG should be no more than 1" aft of the wing leading edge.
Torque roll at full speed indicates that either the motor is bogging down, or your wing is warped. Check for the wing warp first.
Nosing up, I dunno...I've never had one do that, but it may be related to the CG issue. Make sure the power pod is in straight.
You don't want thrust offsets on these as that can cause some minor, but really weird tendencies at full speed which are both annoying and limiting of maximum performance.
Let me know what you find out and we can proceed from there.
Recently purchased a couple kits. So far 111 mph on 6s battery, 2308 2450kv motor with graupner 5.5 x 4.3. Easy hand launch and great flying. 4s battery produced 94 mph and instant 180 degree turns possible. View attachment 225440 Enlarged plans for my club racing with 75 mph limit. 35 inch wingspan flies great. Moving CG will produce smooth turns to radical 180 degree turns. No tip stalls, just slight wing lift with eight rubber bands.

I just hate when that happens, but it also says something for how hard we fly.So it flew...
OH NO!!!!

So...don't go above 75 mph with the foam wing spar. You could put a piece of yardstick in there, or...
