Fixing An Indoor RC Blimp or Flying Saucer That Has Poor or No Lift

If your indoor RC blimp has little buoyancy or will not float it is typically due to Helium gas issues. Here are two possible solutions to get your rc blimp flying around your living room in no time.

Check the Helium Gas You Purchased

Many shops sell weak or diluted helium gas. Weak/diluted Helium is commonly mixed with Nitrogen and will provide less lift, and in some cases, prevent the rc blimp from flying/floating. It is common that Nitrogen is mixed with Helium when filled into canisters. The less Helium, the less lift your rc blimp will have. To get the most pure Helium to fill your rc blimp we recommend contacting a welding supply store as they will typically have the best quality Helium.

What Altitude Do You Live At

If you are flying the blimp at a location where the altitude above sea level is greater than 4,000 feet (1,219 m), you may require a high lift blimp envelope. The higher above sea level you are the less lift the Helium will provide. Above 4,000 feet we recommend using the larger high lift blimp envelope that hold about 2 cubic feet more than the standard size blimp.
