Smaller receiver for 3VCS

[MarkLeeds]

Will be getting a dex410 when they arrive later this month and see the area for speedo and receiver is quite tight. I have a 3VCS and the receiver (R603FS) is on the large side and am thinking I may have issue fitting them both in.

Is there a smaller receiver available for the 3VCS that will have a better chance of fitting or is there anyone currently running a r10 and r603fs in their 410 that have managed to get them in.

Thanks
