This Blade 400 has been in storage for some time now. Lots of good times and good memories with this heli - and some not so good too

I had a YEP 45A ESC laying around and decided to see how it will perform in this 6 year old heli.

Now that low headspeeds are socially acceptable I'd like to get back to that and see how well she does at lower headspeeds possible with Active Freewheeling on this ESC.

The ESC is a bit larger and heavier than most 40A ESCs typical for this size heli, so CG may end up being an issue.

Oh - that funny looking thing is a FlyBar ...

I just realized I've acquired enough bits-n-pieces of helicopter parts and electronics over the last 2 years to actually build up another 550 size Swift NX, for that beautiful scale Jet Ranger fuselage. Only missing a single tail push-rod ball link and Mligosh is kindly sending me a few of his spares - what a guy!

Phase 1 will be building up the pod and boom air frame and getting that all dialed in. This will be a lower RPM heli (1500 range). Phase 2 will be installing it all in the Jet Ranger fuselage. I'll be running on 5S 4000mah packs, with 550mm SpinBlades asymmetrical main blades.

That's the plan anyway.

Let phase 1 begin ! ...Continue Reading

... almost exactly one year after purchasing my pre-owned Flyzone Sensei. It's not the newer (V2) re-designed one with SAFE technology, rather the original one (V1) from 2008. It seems to be in really good shape considering how old it could be. Just the plane and a battery - no transmitter or charger.

The plane has:
  • Stock BL15 outrunner, 840kV motor
  • 30A ESC with 0.7A switching BEC
  • AR500 DSM2 5-Ch receiver
  • 3x 13g metal gear servos (ailerons & elevator)
  • 1x 37g standard servo (rudder & nose gear)
The battery included in the deal is a 3200mAh 3S 11.1V 15C Li-Po.

Everything appears to be in working order. I'll be using one of my DX6i's (or both for buddy boxing).

I've got a bunch of 3S 2200 lipos (with XT-60s) so I'll be using those (with XT-60 to EC3 adapters) along with the 3200 battery included in the sale. It's great having the same batteries for my 450 helicopters, my Flyzone Sensei, and now the E-Flite Apprentice.

I've heard that the AR500 was prone to brown outs, the stock motor's base (made of a plastic like material) can get hot and melt, and the main shaft can get knocked out of alignment easily due to the motor's plastic-like features. I also realize the ESC has a rather weak BEC (700mA). And the wheels are small - not good for grass at all - thus the prop is only about an inch from the ground. All things that I'll keep an eye on for sure. But this plane has obviously been flow at least a few times successfully, so I'm not overly worried...Continue Reading
