I dug up an old copy of RCJI (Jan 95) and there are a few pics of a mod done by a gentleman by the name of Angelo Minici. Its on pg 11. He mounted dual Ramtec/OS91s in his Byron F-18. Looks similar to the F-4 install on the Tom Cook F-4. Yeah its tight but it fits. He even went so far as to make his own scale gear. Dual Byroblasters would prob not fit. All in all a spiffy looking aircraft.
