Is this a genuine HOBBYWING 60 Amp, or a knock off ?
colin weaver replied to colin weaver's topic in ESCs (Speed Controllers)
thanks, Folks, I think mine looks `iffy' regards, Colin W -
Martin, as you know I am generally a fairly careful `old fart'. I did get in touch with RIOT/ max-thrust, and had an e-mail reply stating the reason they added the recommendation for 2.4 GHz was that 35 MHz Rx's were often too big to fit easily into the rather restricted RIOT radio bay, which has big thick foam fuz walls. As of two days ago 27/03/2019 the RIOT was flying as if on rails with the `Schulze Alpha DSP processor Rx' on 35 MHz and my trusty FF6. My gear is always stored in the house, much to the consternation of my Wife and I do look out for black wire corrosion. Oh, and maybe we should think further about any more `maiden flights' taking off towards the Village ?? regards Colin Weaver.

Hobbywing 60amp esc
colin weaver replied to Douglas Wheelhouse 1's topic in ESCs (Speed Controllers)
Does this ESC look genuine? It is a HobbyWING UBEC 60 AMP operating at circa 53 KHz re the UBEC. It reduces the radio range big time on 35 MHz. I have a switch in the positive line, and the signal and negative are not switched but permanently connected to the Dual Conversion Futaba FP-R138DF Rx chanel 3 (Throttle) regards, colin weaver Edited By colin weaver on 29/03/2019 00:57:02 -

Electrifying a WOT4 Pro ARTF
colin weaver replied to David Pearce 4's topic in General Electric Flight Chat
Posted by Bruce Collinson on 20/11/2018 14:00:37: David, There's no panic to answer your question then! I know the feeling. I can't speak for the Pro version but I'm on my third standard ARTF in two years (don't ask, pilot error) and they all flew on the Ripmax Quantum 40 motor and mostly 5A 4S LiPos. None needed noseweight. I appreciate that your LiPo will be a bit lighter than mine. I left the standard elevator pushrod in and upgraded all the clevises to metal. If I really wanted to lighten the tail end I'd try a carbon tube pushrod and maybe risk the plastic clevises, than look carefully at the tailwheel, and finally consider some judicious lightening holes in the tail surfaces. Last time it needed attention I dug out a slightly larger Overlander motor and was about to start drilling to fit when I realised the bullet connectors are larger and contemplating changing all 3, I lost the will to live but next MOT I'll try it. If you're buying a motor especially for it, this might all add up to a no-ballast solution with which I agree entirely. Whatever you decide, good luck and if it's a Pro do please report back. BTC -
early Futaba and Fleet A friend lent me a 1960's two channel Futaba am 27 Mhz , when my son was into model cars, about 25 years ago. The internals of that looked like it had been soldered up using an 8 ounce copper bit, the type you heated up with `blow' torch, or a soldering iron `furnace', which I dimly remember from my GCE `O' level in Metalwork, in 1964. And then there were the early Micron Rx's, also available as kits ..........those were the days (not). YMMV

If anyone wants the black ERA stickered 35 Mhz Tx's (x2) , very clean, for a museum collection, along with various Rx's and and the odd servo kit, PM me and they are yours for the P&P cost. They have been stored in the house for the past decade, and I am getting my ear bashed re my ever expanding collection of R/C `junk', according to my Wife. (She has also sent me out in the cold to tidy up my Garage. The mere fact that she can only get 18 inches into her shed/greenohouse escapes her ! ) I am also on Facebook, with a 1990 `electro- Glider' pic. Regards, Colin Weaver

I think the type approval was with the ERA, which I think meant Electrical Research Association. I think this was at the time we were moving to 10 kHz channel spacing ?
-
The later black Tx's had a UK type approval sticker `SMAE/35/ERA.82/FCS.02' so I guess these wre not splattery re the frequency spectrum......?

Is that the John Duncker, ex of the Luton club, who departed to sunnier climes on retirement ? I used to man the 35 Mhz Tx control tent, at public Club events, with the late Les Townsend , but I do not recall ever testing a Fleet Tx. Some of the PCM Futaba Tx gave strange readings at times ..... ? We discussed that with Mainlink, who supplied the Frequency Meter, and it was concluded that they were OK. My two Fleet Tx's gave `spot on' frequency read outs, but by that time I was moving to a Futaba FC-18, for helicopter use. That was fine, until I used a PCM Rx, and got `lock out' and the Heli drifted into the ground, with the usual crunching sound of an IC Heli going in. I think Mick Reay may have had the same problem with PCM lockout, but cannot be sure. The Futaba dual-conversion Rx's were fine, even in my electric heli, a Kyosho EP, which I flew for years, until spares ran out. regards, Colin Weaver

I bought my first Fleet Tx, a blue one, in 1978, then upgraded to the black ones in about 1982. I used to solder up the servo kits that Fleet then offered. I had a couple of problems, one of which was a xtal that drifted out of tune. Somewhere along the line I went from 27 to 35 Mhz, but cannot remember when. The pots used in the very early servos were pretty `flaky'. Ernie Strutt, John Marshall and I used geared Mabuchi 380 ACOMS motor units with 6/7 yellow Sanyo SCR cub C Nicads. We pushed them hard as motive power for motorised Gliders, and got a mention In RCM& E n the 1980's, sometime. Now look where electric flight has got to.......... regards, Colin Weaver - ex FDMAC - left in 1985 when we moved to Hertfordshire.
