    Great to see all this new gear being developed .. thanks as always Carsten.

    For those of us in the old backward "yard-pound" world, as Futaba calls it, yes, we would prefer to have turbine EGT in...

    Jan, do you know what the AoA of the wing is sitting on the gear? As I posted above, I have a somewhat recent kit (about 2 years old) and it sits slightly positive AoA .. as I said above I am...

    I have three of them, they start and run very nicely, and as Bob_B says, Ron Ballard at Wren USA is the best in the business. The latest model, the 180i has a really nice internal kero burner that...

    I don't think it's "backwards". The Cortex can take Sbus in, but only puts standard PWM out. I though the question was taking the standard one-signal-per-wire output of the Cortex and combine them...

    Hi Bob, I would think so .. that's an interesting idea since the Cortex does not have an SBus output like the iGyro does. Let us know if you try it!

    The iGyro is listed by powerbox as an "SRS" product, meaning that it requires SBus (or equivalent from other mfr) input. Thus, the 6014, not an Sbus receiver would not work with it. I believe Futaba...

    JohnVH,

    On my R54, I added smoke by mounting one of Dan Gill's wet centerline tanks under the wing. I think it was the one for the F-16. I put the smoke pump in the ECU bay, works really well. Not...

    Anton can confirm but I'd assume the hydraulic nose steering is "passive" .. meaning it has no pump, just a master and slave cylinder and you move the master with a servo, the hydraulics are just...

    just to be clear .. I think gyros are perfectly useful . .the "not much benefit" comment was directed at the gyro menu .. not the gyro!!
