Is yours a newer version? Can you post some pic?

Thanks.

i'm looking at building one of these for FPV, I think i've figured out all the parts required. I'd love some comments on my parts list:
https://docs.google.com/spreadsheet/...F9lYWhtT2JOc0E

Most of it's from hobbyking as that is the easiest/cheapest place I know for most of the little bits and pieces. Locally is just too damn expensive (Would double the price of this plane easily.)

Specifically:
How will the plane go with the 6000mah 6s?

Will the Mercury Alloy 12 blade 90mm 1900kv EDF unit fit the aircraft?

Anyone have any idea of what top speed can be expected?

Jets typically don't lend themselves very well to FPV due to the speed.
The Mercury will fit. Speed likely 100-120 mph on good 6S.

@foo: I'll post some pics.

Hmm, well that's slower than I was hoping. Not bad though I guess for 6S.

The fastest I've fpved is 295km/h. I've been doing this since 2008, my first FPV plane was a massively overpowered F-27 Stryker I'm getting bored of flying far and high again, getting bored of helicopters, so now I want something for fast and low again - it's been 2-3 years since I've had something properly fast (over 150km/h)

I might have to get some larger 4S batteries to make some 8s packs out of (can always use 4s by themselves!)

One of my clients (I work in the R/C industry as an electronic design consultant) purchased the jet and fan for me because i was complaining about being bored with gliders.

Now I just need to get the other bits and pieces - most of the FPV gear I already have lying around as with many of the other parts. Servos is going to be the big expense and the ESC.

OK well then speed wont be an issue
This would actually be over 150km/h as I quoted in mph.

Sounds good! I switched my ESC choice to a Kforce 120A HV, so I have the option of 8S if I want more. My friend and I fly 850W bixlers, and 1200W Easygliders... so I'm guessing that more is going to be the order of the day, "because we can."

I may order some of the parts this weekend.. do the servos I have in my spreadsheet (for convenience: https://docs.google.com/a/rris.com.a...tT2JOc0E#gid=0) look like a good choice? I have most of the other parts lying around - just need the servo and esc.

I looked over your spreadsheet - impressive!
I would probably go with something stronger for the flaps but other than that it looks OK.

Thanks, you're right - that is a bit pathetic, how about:

I completely agree. Failure in flight is far far more expensive than doing it right the first time. An extra $7 per servo vs $2000 of onboard equipment and airframe... seems an easy choice to me.
