Replacement canopies for our 50cc planes can be purchased below. The standard price shown is for a canopy to be produced at the time of order and air-freighted as quickly as possible from the factory direct. This allows for a more custom match to your plane and the most economical method of production. We will contact you with any questions about the batch number of your plane to make sure we get an ideal fit for you. The complete process from time of order will take about 8 weeks.

You can choose “Express if possible” below, and if we have a canopy available we can ship to you at 25% more. Please contact us with any questions.

The NEW Fortitude V2 gas tanks are here!!!

*Fourtitude has amended their fuel tanks due to federal regulations on shipping fuel containers. Check out the video below to see just how easy it is to assemble the tank!

Make sure to upgrade asap as this new and improved design is the cutting edge of next generation RC gas tanks. You are probably familiar with the old design- with the the line-in and the vent nozzle on the top of the tank and the line running to the engine on the cap. Because there are so many different fitting and sealants, there are alot of places where something can go wrong or start leaking.

The V2 design eliminates ALL of these problems with ONE SIMPLE DESIGN..... ALL nozzles are in the removable cap which has TWO rubber gaskets and is ONE SOLID PIECE, which includes the vent tube and filling tube. Fewer parts = Fewer problems.

Fortitude has hit the target with the V2 Tank and as always, is the best quality you can get!

Fortitude (or 4titude) gas tanks are high quality, crystal clear plastic tanks, that take the guesswork and worry out of your tanks. You can clearly see into the 4titude tank to know if your line is still flexible and your clunk is in place! Fortitude tanks include the foam, the Velcro and the tubing to hook to your engine!

4titude tanks are SUPER light, in fact, the lightest commercially available tanks on the market. They use aerospace grade adhesives to ensure long life. 4titude tanks are also made of seamless plastic, making them fully resistant to splitting!

The included clunk is filtered as well.

V2 Features:

• Injection Molded Single piece glass filled nylon fitting manifold. Light weight extremely strong material that creates a very easy to plumb and compact fuel tank.


• Dual static O-ring seals, designed utilizing the latest aerospace engineering technology, to seal fluid even under high pressure.  V2 has one potential leak point and with the redundant static seals we have double assurance it will never leak.


• Plumbed with a filtered clunk and an extended fill/ drain tube to make it easy to drain the tank completely.


• Zero protrusions/ fittings on the outside of the tank to interfere with tight airframe installations.


• We took care of making sure there is zero guess work involving installation. 3D diagram included with each tank showing how to properly plumb your fuel system for the best results.

Note the length dimension is from the back of the tank to the front of the fitting/tubing barbs.

Fortitude tanks are compatible with ALL oils, synthetic and non-synthetic. Fortitude uses PPG Class B sealant. The expert below explains how high tech and quality of a sealant it is:

“PPG Class B is an aircraft integral fuel tank sealant. It has a service temperature range from - 65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This material is designed for fillet sealing of fuel tanks and other air- craft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after pro- longed exposure to both jet fuel and aviation gas. "
