I have an 8FG and have the included rx as well as a 617 that came
as part of the Tower package deal. Is there any advantage of one rx vs. the other for a CCPM helicopter using analog servos?

Also, what's the best way to deal with the antennas on a 450 helicopter?

Thanks, Scot

The 6008 that you got with the 8fg is a 2048 res + HS rx. You need to use it in normal mode if you use analog servos . The 617 is a 1024 res rx and would be my choice for the 450 and save the 6008 for bigger projects. The main difference is resolution. They both will work great!

Standard receiver for the 8FG:

Each end (the very end part outside the plastic sheath) should be 90 degrees to each other for OPTIMUM reception. There are many ways to do this. To play with it, just lay the receiver down and see how many ways you can make the two short ends 90 to each other. They don't have to be in the same plane. Example, one end can be straight down and the other out the side, 90 to the other. Very easy to do.

Is it bad practice to ziptie the antenna to a carbon rod, like the tail boom brace?

Thanks for the info!

Yes - carbon fiber shields the antenna from the RF energy. If the antenna is run along the rod, it can sheild almost half its view.

The actual receiving part of the antenna is just that 1.5 inch silver wire at the end. The rest is a coax lead to allow to position the antenna easier. One easy way is to mount the coax leads by some silicone glue, sticker tapes, zip ties, whatever else - and then make the silver ends stick away as little whiskers. If the canopy (fuselage) is not carbon or metal, that also should be fine to do that inside. For carbon or metal fuse the whiskers should stick outside. Btw also if the canopy gets covered by water ( in a rain or in a heavy mist ) or if the antenna is obstructed by metal or carbon parts - this might also create an RF "shadow" affecting reception of the signal from the Tx.. A good practice is to space the whiskers a few inch apart and with their directions at an angle ( ideally close to 90 degrees ).

However, afaik, most helis, especially 450 size - are flown rather at close distances from the TX (compared to large planes ) - so I would not be surprised if these dual antenna RX'es would still work almost regardless of the antenna location and position...
