I know, but the guys over here probably don't so I'll ask for them as they'll be interested in the answer. "What are you going to do with it when its finished".

Drawings sent Dean - hope they are what you were expecting

Hey yea the drawings would be fantastic, and if I'm not pushing my luck too much could I possibly aquire a copy of the ED racer and super tiger as well??? ole mate?? LOL

Yea i had a burst appendix that went septic so it was a close call al right, nearly checked out of life. made it to the hospital tho and 4 hours of surgery later saw me stuck ina hospital bed for 6 days on intravenous antibiotics, then home to bed for a week. Slowly getting back onto the horse so to speak.
Cheers for now

3/ The super charger is a vane type with four vanes.

Ah - a Shorrock-type blower. What are you going to use for the vanes?

AS

[777engman]

Hey there Allen,  the rotor vanes are made from 1/16th phenolic.
Also Ramon got the drawings for the eta's mate cheers for that. Also loving the work on the automatic 5 mate really fantastic.................. I am getting seriously tempted to try an inline twin version tho................... maybe.   
Dean

Hey Pete how you goin mate? At this stage the plan is to get it running and mounted on the running stand till its run in and all the testing is completed, then I may well be tempted to build a 76" span ME 109 c/line model to fly it in...... maybee???????? Heck of a lot of work so we'll see what the future holds.

Cheers

Really Dean - wow I hope you've got a real strong arm - no, two of 'em -  and plenty of weight to keep you upright  That would be one big C/L model to hang onto - a (very) strong bellcrank would be in order too 

The Ato drawings are just pencil ones done before the advent (for me) of AutoCad. I'll get them scanned for you at some stage.

My sympathies over the burst appendix - that's a very serious situation. I had one of my diving crew suffer it off Sicily - very near lost him too as the client was very reluctant to send a chopper out late at night - he too was a very close call. Having survived that I heard later that he lost a leg in a diving accident when a wire rope pulled tight around him - Not so happy days

...or perhaps fly it on 500ft lines. I would suggest using heavyweight laystrate rather than the 3-strand stuff, and use a weightlifting belt for spinal support (and also consider a good pair of hermetically sealed underpants)...

LOL yea the line tension does  get a bit heavy at times, although i do have a bit of flying experience with larger models here"s a photo of my P61 black widow doing 100 plus mile an hour on 60' lines. Span is just over 56" power is 2 enya 29 glo engines. The other is my JU EF 112 with 2 enya 35 glo's, span also just over 56"
Cheers for now
Dean

P.S. Also have a 72" span PBY 5A Catalina ready to fly as well. c/line with electronic throttle control.

[Ramon Wilson]

Lovely models Dean but 100mph plus  I don't dispute it but are you sure - I've just worked that out at 2.75 seconds a lap - I'm feeling rather giddy just thinking about it.

You certainly have some big models and the proof is in the pudding as they're in the air and on the lines  I can well imagine the line tension. Haven't flown anything that big or heavy other than large aerobatic models. Not particularly heavy on the lines until flown in strong wind (which always seemed most of the time in competition) then you do begin to wonder about the integrity of the lines and control system That said never seen the lines part due to tension 

Last picked up the handle in 2006 - now where has that time gone 

Regards - Ramon

[777engman]

Yea that sounds about right, we clocked it at just over 2.5 sec's per lap on full noise. Flying models like this is something if have spent most of my life doing. When your flying these the concentration overcomes the giddiness, works for me anyway. The P61 is fully stuntable too, inverted and outside loops especially nerve racking, lazy eights are a breeze.

[Ramon Wilson]

Hell Dean - now that really is something. I can well imagine the wind up in consecutive loops - assuming you do doo consecutive loops 

I was never affected by giddyness - just a figure of speech - but I don't think I'd want to be hanging onto that in a stiff breeze 

What type of line and thickness are you using?

Ramon

[777engman]

Here's the next stage of the build, cylinder heads and fin blocks.

[777engman]

And here's the rest of the progress, Ramon, I think I am not doing the picaso web album thingy properly or something as the url won't insert the photo images
dean
I almost forgot to describe the process
1/ square up the block
2/ drill and countersink the bolt holes
3/ separate the head from the fin block and surface the 2 faces
4/ bolt the head/fin block assy to the engine block
5/ setup in the mill and centre the cylinder holes and pilot drill
6/ machine the rebate for the glo plugs
7/ remove the cylinder head from the fin block and rebolt to the engine block
8/ machine the cylinder holes and ream to final size.
9/ set the engine block up in the mill on a special fixture to machine all the outside surfaces into profile and and cut all the cooling fins
10/ remove from the engine block and clean up, set up in milling vice to machine the transfer ports in the fin block and engine block
11/ change set up to machine exhaust ports into the fin block.

All done.
cheers for now
Dean

[Ramon Wilson]

Dean - your enthusiasm for what you do has such an infectious exuberance about it 

I often bemoan to myself the fact when doing two or more engines that I've got all those holes to do again - Hmmm - pales into insignificance by comparison. Very nice work indeed.

I will PM you at some stage re Picasa - have to leave now for a funeral and then it's back to get set up for the exhibition.

Just marvellous to see, Thanks.

Cheers, Hugh.
