Fourtitude R/C offers three different size RTU gas tanksl. RTU tank with mounting material these include: A high quality double sided hook and loop mounting strap, a precut to shape foam pad, and Fourtitude R/C blue fuel line to plumb your aircraft! These crystal clear plastic tanks are square shaped which makes mounting into your aircraft very simple. Every tank is QC pressure leak tested and is resistant to gasoline with up to 10% Ethanol.

Taking the guesswork and worry out of setting up a gasoline fueled model airplane! 

  •   Ready to use right out of the package. Just strap it in and fly!
  •   Crystal Clear allowing quick visual checks of any possible pollutants in your fuel tank. 
  •   Lightest commercially available R/C fuel tank on the market. Many cases less than half the weight of the older roto molded “standard” fuel tanks.
  •   Aerospace grade adhesive used in assembly to assure the tanks will hold up to many high G loaded flights! 
  •   Incredibly resilient seamless plastic making the dreaded stopper splitting/leaking a thing of the past.

- Filtered clunk assuring a smooth running engine.


8 ounce - Length 5” x Width 2” x Height 2” - Weight 1 ounce

These are perfect for the new emerging 10-26cc size spark ignition engines. In fact the Evolution 10cc recommends using a filter clunk configuration like these tanks offer. If you own an Evolution 10cc we highly recommend this tank. It is ok to use muffler pressure that the Evolution engines require. Average flight time with a DLE 20 is about 11 minutes.

12 ounce- Length 6 1/4” x Width 2 1/8” x Height 2 1/8” - Weight 1.4 ounces

All of our customers have been requesting a tank that will squeeze into a 20cc size aircraft and also work well in the 30cc size aircraft when slightly lower flight times are acceptable vs. our 16oz option. Well we have been listening and here is the answer! Average flight time with a DA35 is 12 minutes.

16 ounce - Length 7”x Width 2.5”x Height 2.5” - Weight 1.5 ounces

Compact size allows these to fit 30cc airplanes but they have large enough capacity for up to a 50cc airplanes. Average flight time with a DA50 is about 10 minutes.

32 ounce - Length 8.5” x Width 3” x Height 3” - Weight 2 ounces

Compact size allows these to be used in 60cc airplanes but have a large enough capacity for up to 120cc airplanes. Average flight time with a DA120 is 11 minutes. 

These can also be used together if 64 oz's is needed. Use part #FORA1005 Tee Fittings 1/8" to plumb them together. Tee each vent line, fill line, and clunk line to each other. Then plumb your lines to the normal locations as if they were off a single tank. If you are using a dual carb engine such as a DA200, then you do not have to tee the clunks. Use one clunk line for each carb. The vent and fill fittings keep the tanks fuel level even during flight. Note this is the only approved method of plumbing two 32oz tanks to work in unison. If you plumb them any other method it will damage the tanks. Yes we have tested this and it works perfectly. In fact Andrew Jesky won the 2011 TAS using this very setup.

    Pick Up Line too long

    Posted by Chris on 20th Sep 2015

    Ordered 3 tanks. I love these tanks, they work flawlessly. Only problem is 1 tank had the clunk line too long and was hitting back of tank. I wish they would have caught this before shipping. Too costly to ship back. I would have waited for new version as they came in just after ordering if I knew.

    I have installed many tanks in airplanes over the years and last year I tried one of these. I will always use them from now on.

    great tank

    Posted by fred on 11th Apr 2015

    Saves a lot of work-ready to go, light-my 3rd one.Take care when hooking up lines esp. on vent & fill outlets as they are relatively frail but do the job well.
