Most FPV pilots end up ordering printed parts one at a time: an antenna mount after the first crash, a GPS holder when they add GPS, arm guards when the stock ones split. Our kits bundle the parts a specific build usually needs and price them below buying each part separately. This post covers exactly what is in each of our three kits, what every part does, and how to fit them.

All three kits are printed to order, so they are never out of stock. Each part is an open design licensed for commercial printing, and the designer is credited on each part page. Kit prices are listed in PETG. You pick the material, color and quantity before checkout.

GEPRC Mark4 FPV parts kit for DJI O4 Pro

The GEPRC Mark4 O4 Pro parts kit is $22.92 for four parts, about $4 less than buying them individually. It is aimed at pilots moving a Mark4 to the DJI O4 Pro, whose two antennas need a new rear mount.

What's in the Mark4 kit

Mark4 O4 Pro antenna mount: a rear mount that holds both O4 Pro antennas on a Mark4 5-inch frame. It has no GPS slot, because the GPS gets its own mount.
Foxeer M10Q-250 GPS mount for Mark4: holds that GPS module on the frame.
Mark4 ELRS receiver holder: keeps an ELRS receiver secure instead of taped to the stack.
Mark4 HD 5-inch GoPro mount: a top-plate action-cam mount, tested by its designer with a GoPro Hero 9 Black.

Installing the Mark4 kit

Fit the antenna mount to the rear standoffs first, then feed both O4 Pro antennas through and angle them apart.
Mount the GPS with a clear view of the sky, as far from the VTX antennas as the frame allows.
Seat the receiver in its holder and route the receiver antenna away from carbon and motor wires.
Add the motor guards and landing gear, then check that nothing touches the props at full motor deflection.
Bolt the GoPro mount to the top plate last. Use a strap as well, not just the mount.

For more O4 Pro options on other frames, see our O4 Pro mount guide or the GEPRC Mark4 parts collection.

GEPRC Mark5 FPV parts kit for DJI O3

The GEPRC Mark5 O3 parts kit is $24.99 for four parts, about $11 less than buying them separately. The Mark5 is a very common 5-inch freestyle frame, and many of them still fly the O3.

What's in the Mark5 kit

Mark5 O3 air unit mount: a replacement for the stock O3 mount with larger cooling inlets and a lower air passage. It fits both the standard and DeadCat Mark5.
Mark5 ELRS antenna mounts: receiver antenna holders, including a version that takes rigid spacers so screw clamping force stays on the frame rather than squashing the plastic.
Mark5 arm guards: match the stock guards with less excess material, so they weigh less.
Mark5 front protector: a lighter, better-cushioned front piece that lets you tighten the lower screws without the part bulging.

Installing the Mark5 kit

Swap the O3 mount first while the frame is open. Check that the camera sits square and the coax isn't pinched.
Fit the front protector and snug the lower screws evenly.
Press the arm guards over the arms. TPU guards are a tight fit by design and relax slightly after install.
Install the ELRS antenna mounts. If you are using the spacer version, put the spacers in before tightening.

BetaFPV Pavo20 Pro parts kit

The BetaFPV Pavo20 Pro parts kit is $19.52 for three parts, 15% off the separate prices. The Pavo20 Pro is a small cinewhoop, so these parts are light and fit-sensitive.

What's in the Pavo20 Pro kit

Pavo20 Pro LiPo battery protection cage: protects a BetaFPV LAVA 550 mAh 3S pack and holds the balance lead out of the way.
Pavo20 Pro GPS mount: a nano GPS holder that attaches to Pavo-series canopies so the GPS can move between canopies. It comes in tight (V1) and front-open (V2) versions and also fits the Pavo20 and Pavo Pico.
Pavo20 Pro landing gear feet: light feet that stop the quad tipping over on its 3S pack, for clean takeoffs.

Installing the Pavo20 Pro kit

Fit the battery cage to the pack before strapping it on, and route the balance lead through the holder.
Clip the GPS mount to the canopy. Try V1 first. Use V2 if your GPS module sits proud at the front.
Add the landing feet and check that the quad sits level on a flat surface with the battery installed.

Which material for kit parts?

For anything that takes a hit, such as arm guards, front protectors, antenna mounts and landing gear, we recommend TPU 95A when it is in stock. It flexes in a crash instead of cracking. PETG is cheaper and stiffer, and it is fine for parts tucked inside the frame. Our TPU vs carbon-fiber nylon guide explains the trade-offs in detail.

FAQ

Does the Mark4 kit fit Mark4 clones?

Many Mark4 clones copy the standoff layout closely, but not all do. Compare your frame's standoff spacing with the original Mark4 before ordering. The fit guarantee covers the listed GEPRC frame.

Can I use the Mark5 kit with an O4 Pro?

The air unit mount in the Mark5 kit is designed for the DJI O3. The other three parts don't depend on the video system. For an O4 Pro, look in the O4 Pro mounts collection.

Can I order kit parts in different colors?

Yes. Each model can use up to 7 colors, one color per part, so you can mix colors across a kit.
