EF1 motor shaft configuration
Posted: Mon Feb 14, 2022 12:34 am
Apologies if this question has been asked and answered, but my forum search hasn't worked and the package insert instructions don't mention it ... I just got 2 new Avian (Rimfire under Spektrum label) EF1 motors and they appear to be set up for a "front firewall" installation. Obviously they need to be configured so the fixed portion (firewall and X mount) are in back and the spinning bell part is in front as God intended. I loosened the collet on the shaft where it comes through the bearing, but even with the set screw removed it doesn't want to slide off so I can't swap ends of the motor shaft. I don't remember the earlier Rimfires having this issue.
Before I use my vast collection of torches, hammers and cutting wheels, is there an easy way to deal with this?
Of course I could leave it as is, with 3/4" of shaft sticking backwards through a hole in the firewall and bolting that rigid threaded motor stud on the front, but it would be a lot more elegant with the shaft turned around so I could use a tapered collet or E-Flite spinner directly on the shaft.
I'm a bit disappointed these are being supplied this way since almost exactly 100% of the EF1 customers (as well as any potential E-Q500 customers) will want to use it in a rear firewall configuration, and it's marketed as an EF1 motor. But I'll do what I gotta do.
Thx,
Duane
