Our LiFe Batteries (also known as A123 Batteries) have huge advantages over most other options.

1) LiFe Batteries are lightweight - as light as Lipos
2) LiFes are safer than Lipos (do not combust easily like lipos)
3) LiFe Batteries supply a constant voltage (They stay right near 6volts from start to finish ensuring consistent flights)
4) Run Life batteries to your servos and ignition without regulators (For extra caution some people run a regulator to their ignition still)
5)Life's have a high Charging Capacity. Charge up to 5amps, allowing you to charge them up in MINUTES!

****Batteries must ship surface mail due to hazmat restrictions and have been taking longer to reach destination****Express and Priority mail are not an option for surface ground mail.

The 2100 or 3000 Mah can be used as a SINGLE battery system for 30cc planes. (we recommend spliting the lead and put 2 JR leads on, to run to the receiver and the other to ignition). You can also run a single 3000 Life Battery on a 50cc Plane.

The 1450mah LiFE Battery is a great option for those that want a separate battery for ignition and receiver (if you are running FM or hesitant to use a single battery system). The 1450mah Life is a great battery for the ignition for either a 30cc or 50cc sized plane

We recommend the following:
On the MXSR (2) 2100mah, or 1 3000mah placed on the mount box or front of the plane. It is a bigger plane and will do well with the extra voltage and weight.
Other 30cc planes - (1) 1450mah for ignition, (1) 2100mah for receiver or for a lighter set up
(1) 2100mah for both (split the wire to 2 leads) OR (2) 1450mah (one for ignition one for receiver).

50cc sized planes (1) 1450mah LiFe battery for ignition and (1) 3000mah LiFe battery for receiver or, for a lighter set up
(1) 1450mah for ignition, and (1) 2100 for receiver OR (1) 3000mah LiFe for both receiver and ignition

Redwing RC Fuel Tanks (Gas Tank)

Redwing RC Fuel Tanks

The NEW Redwing RC 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.


  • Size: 8 ounce (236 ML)
    • Length 5 3/8” x Width 1 7/8" x Height 1 7/8” (136.5 x 49.5 x 49.5 mm)
  • Weight: 1 ounce
  • Fittings are part of the cap/ internal tubing
  • Filtered clunk
  • Super light!
  • Crystal clear
  • Seamless
  • Includes: Tank/foam/velcro
  • Fourtitude Tanks are compatible with gas engines only. (Not compatible with Glow fuel)




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. "
