Vulture 3500 E glider build
Vulture 3500 E glider build
Thread starter's only
New 3.5m of thermal ship from MVM
Here's the glider and electric versions for comparison
This is for F3J
Big feature is radio access under wing seat
Slim but roomier fuse
A20 6XL geared running 16x10 Aeronaut on 3s
Here's the system. Running a seperate Ubec and utilising telemetry with Hitec Optima 9 rx for main pack Voltage and Voltage going to radio
Motor mount installed with thick fillet of epoxy and colloidal. Carbon lip done by manufacturer.
Esc runs on bottom of fuse
Rails run down the Esc and Ubec. Lightened ply plate screwed down onto this and sites the Lipo.
With light weight motor used need to move lipos quite far forward so ply plate allows an adjustable position above the esc etc. Access is via 6 screws.
Lipo Hyperion 3s G3 45c 2200mah
For 90mm ish CG lipo right to front, move to rear no problem but need more wt in this install if CG needs to be more forward.
Installed. Hatch really simplifies things. This will be access for Rx too. Snakes factory fitted.
MKS 6100, 0.001ms deadband, fast 0.12s for 60 degrees and 2kg real life torque! All in 9.5g package.
New ply plate made to fit servos
V tails are big and super light. Flexible hinge- no scraped out hinge line!
Elevator rod s sit inside moulding, which is pre drilled. Ball links angled to give full travel. Quite a long linkage so good torque can be achieved here.
Tail cone needs taping maybe some tape wipers too as none factory installed. Very light tails though.
Nicely designed and pre fitted horns. So much sturdier than G10 horns. This one's a flap.
Flap with clevise installed. It's ground down and slot extended a few mm but still a very clean design.
Flap horn geometry is quite good, tall enough to use a 10mm servo arm and achieve full brake at around 80 degrees and easily 10mm up travel.
Aileron opening even smaller. Really clean linkage.
Aileron servo trial fitted with all bits made. Huge well, tiny servo. Because of small arm needed maximum servo travel utilised by using a 5mm arm.
Side view showing bearing housing encased in ply support. Thick G10 strap adds strength and stops top skin from flexing with servo loads. Without the bearing kit these tiny servos will quickly wear because side loads on the head.
MKS6125H (same spec as mini). I always glue and strap. So doesn't matter to me which way lugs are orientated. Thicker strap here just to fill the space. 16mm servos no problem.
All hooked up and ready. Stainless steel pushrods really, strong install. If arm breaks bearing shafts has flats to turn and remove arm. Servo breaks, cut strap, twist servo and out it pops.
All wing auto-mating plugs. D plugs in centre panel and Mpx greens in tips.
Its huge and so light at 2.2kg. Better than some gliders have turned out. Its balances at 92mm so may need a few more ounces- maybe not but flying is another day!
Special MVM section. Whatever it is it appears to work very well by all accounts with the glider version- same wing. Only difference is E fuse.
I think these will make effective brakes!!!! Full carbon is marginally lighter than Dbox. Made with expensive 65g carbon.
This is factory done. Incidence and reinforcement. This is not just a chopped off nose!
Sides are high as the canopy opening is just big enough for access. Nose area is much less 'twisty' than most.
