test stand for the little ones

Modified this by just drilling 2 holes for the PAW 55 spacing really for the Coxs got it from Cox International, no way will my stand take the little ones, holes in the PAW for mounting really small 2/56 or 2mm screws needed martin

using the regular plastic mount for the engine a lot more effort and needs some run time before going into a plane

That's the first gold anodised PAW 55 I've seen Martin, though I've seen them with pink and red fins and spinner in the past.

Hmm-must be a 'special' done to order then-I also note the prop driver is anodised as well, which isn't normal PAW practice............

Chris interesting saga on this one. Years ago bought #29 of a limited series (200 MADE) of the millenium issue from Just Engines UK it was plain no anodizing , being heavy handed
bent the rod trying to start, ordered new rod from Eric Clutton here, made a holder for piston used a small punch to remove wrist pin, punch slipped broke piston skirt, crying the blues to Derek he said"send it down to me". turns out crank was cracked also. a few weeks later back from Derek comes a new PAW, the one in photo (boxed) with Owens label in it plus the bits and pieces of the original martin

Martin, my PSP hold down bars have an extra set of 2? holes in them, they are spaced just right for several .10 size engines. When an engine is close to fitting I just use the diagonal two bolts, (2-56). Two bolts will hold a .10 or .15 size engine just fine. You can see the holes in this shot of the Enya .25D. I just flip the bars side to side as I keep the holes outboard so the stiffer part of the bar is inside.

Hi Chris, Yes it's a limited edition.It is part of a series called "-Limited- Millenium Edition" .

I have Engine No. 73 of 200. I got it from Ed Carlson over ten years ago. I paid the regular

price for it; Ed asked if I wanted the regular production or the Millenium version. It runs just

like a regular version, ie: excellent.

Tony I plan on picking op the pieces piston/liner/crank and get the little bugger back up again rod I already have martin

#29 will live again

RE: test stand for the little ones
 
Hobbsy you charged up my old grey matter , thinking about this the current mount uses 2 5/16 bolts to hold the clamps and allow slide in the slots for width, will make up 2 new one and have them project about 2 inchs past front of mount, then do the drill and tap thing for engine hold down the current one as is does not allow clearance to get the muffler on nut
sticks up too high martin

i.e will use same bolts but the extended length of the new clamp bars no clearance issues thenany engine fits it holds the 25s and up now with no clearance issues

Must've been a bit of an outbreak of 'Millenium editions' then-Irvine did 'ME' versions of their 75 and 1.3 Mills replicas as well-you could even buy a matched pair for (IIRC) 200 quid! Looked nice with the black crankcase and deep gold anodised fins. IIRC (again!) there was only a run of 100 of these variants.
Unfortunately I was rather busy watching over a nasty little war at the time so wasn't in a position to do much modelling or acquiring..........

I just bolt my engines to a piece of wood, it doesn't take that many stands to cover an engine range from .049-.15. But then I don't run engines at home, only at the field, and bring a strong clamp.

I'm with Mr Cox on this one-I have a multitude of wooden mounts which I clamp to a sawhorse for running (the sawhorse has folding tubular steel legs so doesn't take up a lot of room in the car when folded). With some judicious sizing, one wood mount can cover a fair range of engines (and you have two ends to use for mounting, as the pics show). The 'small' engine mount-with the radial mount at one end and the beam at the other can handle 11 different engines (mind you the radial mount flange is riddled with holes by this stage!)

Mr Cox-how does the Queen Bee handle with the diesel head?

We have had some really bad weather here and I haven't run the QB properly yet. Just fired it up briefly on an 8x4 prop, can't wait to see the performance.

I have included a throttle lever on my RC stands, and sometimes also bring a workmate to hold the engine stand at the field.

I started off using a workmate, but found that they fell apart from the vibration-and short of replacing every single nut on the workmate with a nyloc one, there wasn't a lot you could do about it. I also got sick and tired of trying to find the missing bolts and nuts in the grass afterwards. The workmate does place the engine at a more convenient height for starting and adjusting than a sawhorse though......

I use an electrical connector block with the throttle wire passing through it as a manual throttle adjust. By tightening the connector screws appropriately you can adjust the amount of friction to the point where the throttle can still be moved back and forth by hand, but vibration while running won't alter the setting.

I must introduce my Queen Bee to that diesel head. It looks like the 09 Mecoa one to me-and I have one of those. My Queen Bee is one of the early ones with the straight reed and spiral spring reed retainer.

Yes the head is the Mecoa, RJL 09 one. I don't care much for the DDD teflon seal type, it simply doesn't work. I have another RJL head for the 05RC too;

Mr Cox sort of did that with the MPJet 061 (there is pix posted) used the regular MacGregor engine count attached to a piece of plywood screwed to a piece of 2x3 martin

Where was that Irvine .20D stored? Looks like lots of oxidisation there ..

RE: test stand for the little ones
 
In a cupboard in the garage-I noticed the corrosion too when I pulled it out this morning to take a photo. Will have to give it some TLC. I suspect its only surface though. None of the others in the same cupboard are showing any signs.

My test stands for small engines consists of a 1950's E-Z Just and some boards.

Edit: Forgot to mention...I clamp the boards to a table.

OK Guys looks like I am gilding the lily ,a few boards a lot easier and quicker than the metal working martin

GCB my test stand sort of looks like yours but aluminum the nuts conventional hex nuts not wing nuts like yours but no clearance for the mufflers on the small engines 15 and up are no issues martin

cubflyman 11-14-2012 09:07 PM

RE: test stand for the little ones
 
Hi Guys; I have an old E-Z just mount, and have taken the carrage bolt out and put it in from the top. and put a nut and washer on the bottom, giving clearence for the muffler on some engines. just a thought. Tom P.

Here's a purple anodised 049Mk1 Chris. Screw in liner and cooling fins as oposed to the current engine with hold down bolts.
Engine wil do 19000 on a 6x3 APC prop, Some performance.
I'm in the process of mounting it in the nose of a Gentle Lady. Should get it up there ok..
I don't know about the gold anodised one but I was of the understanding that all small PAW's were anodised earliy in the peace
with PAW stopping this as a cost cutting exersise.
