Gryphon - even 14" prop doesn't fit the Wasp, you must cut about .4" that it don't strike the wing.

Ah, I see.

Thanks.


Gryphon

Edit: maybe 16/25/1.5S 2990 KV (3050+ actual) would be closer for running similar props.

Heya Gryphon, I was kidding with the 7S, that'd be a tad nuts

Poor wasp was designed for 300W little outrunner, 2kW will be fine



Sweet, ive shimmed the motor/box up to as much as sanely possible, have about a degree down and .5 degree right.. we shall see how it goes

Finally got my pinion to hold on

2060W, 100A, for 7900 rpm, 158mph pitch speed.

Should be adequate...

It flies


Maidened it off a slope at Raglan (west coast of NZ) today, in 20 odd knot winds, baptism by fire.


Maiden flight done with a straight centre peice for a 14x14 prop, got a solid amoun t of get up and go, slower than the X-plane on 4S, but not massively slower (16/35/1 5.2:1 14.5x14) , I say it'd do an honest 140-150mph (and it gets there very quickly )

The extra weight over the old setup means energy retention is pretty awesome, but its lost a little of a its spritelyness with the sticks in the corners, still no slouch though. I Like it

Put lots of G's on it, reinforced wingseat showed no sign of failure.


Now to crank up the pitch and try it on a calm day!

Got some video to have a look at an edit, if its visible Ill upload it.

That was awesome.

I loved the vertical capability of your plane.

It gets my two thumbs up approval, nothings hot, batteries seem fine, and the ICE100 is within the zone of being able to use a throttle (instead of switch). Once the prop bites it launches forward, plenty of thrust to hit the pitch speed in a few split seconds.

ICE100 recorded 95A, and 9500rpm in flight, so its more likely to be around 80A (this is with a straight centre peice)


Whats kinda interesting is that the rolls are pretty axial power off, but power on vertically you can nearly throw it into a spin with the aileron stick in the corner, must be some sorta torque thing. Dispite the big prop, the ailerons are well out of the prop wash.

A few more flights on the straight centre peice, its fastish, but it definetly runs out pitchspeed.

Add a +5 degree centre peice, Whole new kettle of fish, 21" of pitch is a good thing!

Big difference in performance! 160+mph now. Acceleration is down a touch on the straight centre peice, but not horrifically (its still definetly a "hot" liner!)

Loving this plane. Unfortunatly no video, rubbish overcast weather.

LOL!

Chris,
I had my first experience with 23 inches of pitch today and was flabigasted with how fast these perfectly behaved little planes can go on so little power!

We need more of this I say!

(Factual stuff here: http://www.rcgroups.com/forums/showp...0&postcount=29 )

After seeing yours fly Jacko I'm seriously considering keeping my second one and finding a silly fast setup for it....


I think my yellow one needs to stay as a hack with the "slow" power it has now or I'll kill it with eggbeaters

Its a pity you had to leave early man, it really came to life with more pitch! Went from "yeh, thats pretty quick" too "ohh daammmmn"

I have a few spare KPG's here if you want one (also have that GM prop and roll of insulation in the car, doh!)
