| The 3058 muffler will do for the .32.
I'd check to see if a standard muffler will fit first, though. I think there's a good chance with the 222. Standard mufflers certainly fit in the Airwolf. The scale mufflers tuck in beside the engine, blocking access to the low speed needle. They are good if you are tight on space, but otherwise the standard 3033A type muffler (or similar Hatori or KSJ) is easier to live with.
You will need to tune the engine with a standard muffler anyway, or take the box muffler off for every idle mixture adjustment.
My Airwolf kit came with a hex start, so the Sceadu probe should work. A cone-start would require a large, ugly hole in the top of the bodywork.
Without a one-way bearing in the start probe you need to be quick with your hands once the engine starts. You need to disengage the start shaft in the heli from the fan the moment the engine starts, release the starter switch, wait for the starter to spin down, and then withdraw the probe from the hex coupling, in that order. It's not that hard, but you have to be ready for it.
With the one-way, you can just release the switch and withdraw the starter at your leisure.
Removing the probe from the coupling while the starter is spinning is to be avoided, since the probe can damage the bodywork, or fly free from the starter cup.
Does the gyro require a gain control channel? The RD6000 has only six channels, which you will need for cyclic(2 ch), collective, throttle, rudder, and retracts.
Ability to set ATV for the retract channel will be handy if you use normal servos. If you use retract servos, setting radio ATV will have no effect, you will need to mess with the arm lengths to get the retracts set up properly. You'll be doing this to some extent anyway, I guess, since you have only one channel for the front and rear retract servos.
You will need a y-lead for the retract servos. |
