I got lucky finding this message. I hardly ever visit OSE any more due to support on RCG for the DX8. Please e-mail me andy@[deleted] or andy@[deleted] in the future.

Spektrum receivers do not send any signal to the ESC until it connects to the transmitter (ie, finds the frequency(ies) in use by the tx). This is a failsafe operation, preventing it from accidentally arming an ESC when it should not be armed. We do this on ALL our receivers (Air, Marine, and Surface), and have since the beginning and it will not be changed since it is a primary safety functionality.

I have made comment to hasten the recognition and activation would perhaps solve this dilemma.
Waiting for return.

Wayne, if the bec is removed may that resolve this issue with this ESC.

???? .. not with Spektrum, according to millzee.


Spektrum with Rx pack to a Sf240HV is puzzling.. as that bypasses the Spektrum recognition and activation delay issues....but he still faces this <100% problem.

I am using the sf240 in a df35 pirate(single), the esc has no internal bec, I've used a rx pack from day 1. I too have the throttle travel up around the 150 mark and it's helped the issue.

millzee, what speed are you getting out of that pirate?

Maritimo twin
I ran Futaba 3Pk Faast to a Rx603fs with NO Rx pack .. feeding twin SF120
No probs.

Sprintcat40 twin
I run Futaba 3Pk Faast to a Rx603fs with Rx pack .. feeding twin SF240HV
No probs.

Guess Im just lucky ....

I can live with the problem. I love my Spektrum.
Thanks to you and Andy for all the trouble you went to.

From Andy:

Connect the rx as you normally would. This would cause the delay to occur. Now, power it down, then apply power again. This will cause the rx to immediately check the last channel(s) first, causing it to immediately find the transmitter.

I am still confused...a part of old age?...but is this a specific ESC problem?

The way I see it, it is a Spektrum radio problem. Andy Kunz is telling us it is built in as part of the fail safe so motors do not fire up accidentally. It could be a pain in the a$$ to a greenhorn or someone that did not have access to a forum such as this one. Steven obviously has never had the problem. I have only had it twice. Anyway now we have 3 workarounds for the issue and few people seem to experience it. I like the idea that it is built in and I like Andy's workaround. I will not be moving away from Spektrum in a hurry as I find them easy to program and the telemetry and the "drop them in your beer" receivers are two great +'s IMO.

Edited in...
To be truthful, I always try some Throttle Travel on any of my setups just to see if I can squeeze another mph out of them. This is always done carefully so as to make sure the motors shut down with zero throttle. I never presume the radio has found full throttle. Sometimes I get a pleasant surprise.

What are the silicone hoses going to the stingers for? Perhaps the way you are going to apply the Wet Stuff to lube her up!!!



The pictures show just how bad the gel coat finish is on that hull.
Where are AM hulls made?
Even DF clone hulls have a good gel coat. The quality control guy must have been at the doctors the day they packed that hull.

silly cone tubes feed light oil into cavity between stub shaft and brass outer guide ( ~20mm) to lube roller bearings

Ahaa. Seems like a good idea. I am a pussy virgin as you know.

[Xzessperated]

All I can say after just one test of your old Maritimo and a check of your workmanship on that hull is that this hull is gunna (I know you love bad spelling and slang Douggie) fly and be as strong as a brick out house.

Monos have these things too ..I know a top hydro nitro fella has a drain from tuned pipe that feeds to strut ( dunno if it works ) which looks impressive .

i admit pussies are the most fun yet.. two screws at once fighting the other.. counter rotation twisting your ass one way then the other.. great thrill when they're all hooked up screaming wide open .. all under your control.. ... .. yummy stuff.
