Power is from 2800mAh 3s2p Saphion Lithium
Jeti Brushless ESC
Tornado 2815-2000 BL motor
I started with a 7x5 prop, but now settled on 8x5 APC
I'm a great fan of this fantastic aircraft too and I know its not EDF but thought somebody might be interested in my "TSR2B" anyway. Apologies if this post out of order but am sure the moderators will move this post if needed.
This is my first home designed and built aircraft - I started it last winter, finished it by Easter and finally got around to flying it (after lots of brave pills
) at the begining of July. I based the wing area on my Protech Mirage
2000 - worked from the known to unknown. I used TSR2 scale drawings for
the general arrangement/dimensions but on this first attempt I decided
to copy the Tornado-style intakes as modelled in the FCS TSR2 add-on
for CFS2 - much easier to make than the semi-circular intakes; they
could wait for the second build if Mk1 a success. The wing tip chord is
slightly increased from scale plan to increase wing. I used easy
all-sheet balsa construction of differing thicknesses with some lite
ply in higher stress areas like the motor and elevon mounts (KISS
principle again). Power is from 2800mAh 3s2p Saphion Lithium Phosphates
(first generation Overlander sold last year), Jeti Brushless ESC and a
Tornado 2815-2000 BL motor (overlander again). I started with a 7x5
prop, but now settled on 8x5 APC - there is quite a bit of blanking
from the fuz. With this set-up I get at least 10 minute flights before
I notice power starting to drop off and would probably get alot longer
if I throttled back but I just love flying it fast and low! I measured
currents during the design stage to check everything was in limits, but
I can't now remember what I came up with - I guess it must be in the
15Amp region based on endurance - batteries only get pleasantly warm to
the touch after flight but I do have cooling in through the intakes,
past the battery, ESC, down through the fuz and out past the motor. I
use a ramp and bungee for launching, it is safe and gives consistent
results. Anyway, here are a few photos:
