I suppose you can choose to keep the airsoft gun in place and simply replace the airsoft warning LED with the IR LED andmount theDBU's DIN9 connectorin the commander's copula, though itwould be a very tight squeeze. If you were to do this type of hybrid installand stilluse the stock Heng Long transmitter, please keep in mind that the IR system will only fire using the "K" button while the airsoft system would still fire using the transmitter's left-up toggle.

It's an interesting possibliity.
