226 MPH on Maiden
Hi guys,
I already put this in the speed freaks thread but I think a few people missed it so I figured I would drop it in here too.
We designed/created/ and then flew this plane a month ago and got 226 mph on maiden flight on prospeeed radar (and video)
with no spinner (2.4 inch flat plate on the front.... spinner was vibrating too much).
My friend posted the video here if anyone wants to see/hear.

RE: 226 MPH on Maiden
Here's a Vendetta. I think you can see the differences. Way bigger nose (and motor). I found a rear view also to show how much bigger the fuselage is for room. The Vendetta is relatively skinny (as designed of course). New plane doesn't have big ole scoop on the bottom and has a more lancair like tail. There may be some other minor similarities Oh yea, my toes are added in the one photo for reference. I haven't convinced Steve to Lay up more of these as he has commitment issues (to one plane at a time. He moves on to the next before he's done with the last one).

RE: 226 MPH on Maiden
Thanks guys for the links.
Not sure why I would log off then after a while log back on and I couldn't get them to work.
Anyway we were doing about 26~26,500 R'sPM static so I'm thinking around 27-28K listening to it in the video. Also I think the prop is a 8.75 X 9.75 (to 10). Steve can put his pitch guage on there but I'm pretty sure that's the prop.
Thanks for the congrats you guys.

RE: 226 MPH on Maiden
How many watts are you pushing on that thing? I've always wanted a 200+mph electric f3d. The fact that you can taxi it out to the runway with retracts and full throttle control makes me want one sooo bad. Also, what kind of runtime are you getting?

RE: 226 MPH on Maiden
Hey "The tick",
I agree, I saw some Qm40 action and I thought man those suckers are wide open the whole time (90 seconds or so). It sure would be peaceful to taxi out....and turn the motor off in flight....and do go-arounds etc. Anyway, I'm not trying to dog the gasers, I just thought it would be a cool feature. I flew the Vendetta for 5 to 6 minutes per flight. The 7.5 X 7.5 prop setup was a very "stable" setup that didn't overtask any parts of the power system. 70 amps at cruise at 30 volts. (~2100 watts) When we did 201mph we had a 7.5 X 8.5 or so and I didn't keep it wide open all of the time.
Here's the Vendetta:

This new plane really puts a load on the batteries with the 8.75 X 10. If I remember right, The static amp draw was around 160, so 145-150 amps (unloaded) at ~30 volts under heavy load = about 4500 watts. We are going to fly again soon and see how the batteries are. Of course, if Thunderpower is reading this and needs a test/advertising platform for Xtreme V3 35C lipo's give me a call
