what about counterweights ? on that page it said there were two counterweights , one on the back of the engine and one on the prop mount, how would that work on a twin rotor ?

from the rotary performance forum !!!

look at that gearbox ! and the cooling fan ! that looks like the fan out of a ducted fan model aeroplane !

rotary emotions

Wow, cool... The more rotors you have the less counterwheight you need. I think...

Magnus Berglund

Seen that one as well.. look at the gearing!

Maybe watercooling?
If new centerplates are made why not make waterchannels in them and let the rotorhousing stay aircold?

hmm.. maybe to big differens in temp for it..

<Hijack> Hey Magnus, have you got your exhaust yet ? I'll be very interested to see what you think of it as its on my list of things to do before the summer

(was going to get WGT High flow system but their supplier 'Lost' the pattern )

rotary emotions

Not sure if it would be problematic because of temp difs, but it'd be rather complicated... Also, the rotor housings are more important anyway. Maybe we can supercharge it, and put an intercooler on
Actually a fan could cool rather well, and if you would ad water or oil cooling to the centerplate... Let's build a 4-rotor water(or oil)cooled, supercharged, intercooled, rotary RC car, and go for the land speed record.

MikeLMR

whats is the R/C land speed record ?

you could build a 4 rotor engine and use 1 rotor as a supercharger for the other 3,

one of the orginal applications of the rotary was on NSU's record breaking 'quickly' moped it used a single rotor supercharger and it held the moped speed record at bonnerville !

I think all it would take to convert a rotor and housing into a supercharger would be to move the ports ???

Not sure if one rotor would flow enough for 3 others though ? maybee two rotors boosting and 2 rotors generating the power !

I did not want him to send it so we got it during x-mas..
I'll take some pictures as soon as I get it.
How much did WGT want for their?

Back to the Rcstuff >>>
Hmm.. I think we are getting out of hand now.. *s*
I would really love to build this two rotor but I think I'm going to spend the money on my Rx7..
It would cost quite a bit just to get hold of two or more OS eninges..

HIJACKING:
Magnus have you got a specific date yet for the raceday yet???

rotary emotions

Magnus, you don't need two complete OS engines, just one, and as many replacement rotors as you like extra rotors. Sideplate and e-shaft cannot be that hard. The supercharging is more of an idea, not really something to do.... Or maybe if I win the lottery :-)
Kim, there's a Hijack thread nowadays :-)
Anyway: I found a new paintshop, a Mazda dealer I know. His price is much better then what the first guy wanted. Just hope he does a good job. But I think it will work out fine. (hmmm, now I hijaked too)

MikeLMR

yep I think the supercharger was more of me and Bart think out loud *lol*

I think WGT wanted about £550 for a high flow stainless system, but it had straight through silencers and longer headers than the Rotechnics one,

Let me know what you think of it as the rotechnics ones are by far the most resonably priced stainless exhausts

rotary emotions

Mike, when it comes down to rotaries, I hardly think... :-)
It's all feelings you know. That's probable why I'm always broke :-)

Andreas

went to the postoffice for the shipping costs and supermarkets for boxes.

postoffice:
the sending to your country is Euro 5,75 (dimensions of the parcel combined with weight and this is _not_ the slowest by train/boat)

boxes:
well, the boxes @ the supermarkets are not good. either messy/rotten/weak/stink/too small but the postoffice sells boxes for Euro 3 so i want to send them with a lot of used Dutch newspapers that you can read for free ...

so the total cost for either one is Euro 8,75 to ship to your country.
my paypal account is andreas.wijting@bbned.nl (internationally verified)

i can only send the body/bodies on thursday or saturday

greetings,
Andreas.

Andreas

so

1 body: Euro 37,75
2 bodies: Euro 66,75
3 bodies: Euro 95,75
4 bodies: Euro 124,75

and so on

greetings,
Andreas.

Andreas

rotary emotions, got your payment. will make the package and send it thursday!

Magnus Berglund

Andreas:
I'll send you the money tomorrow.. so make a package for me as well.

//Magnus

Magnus Berglund

dooohh..

Will be a few days before I can complete my paypal account.. stupid codes and stuff..

I'll send you the money asap.
//magnus

MikeLMR

me too

bare with me though I'm new to pay pal

Magnus Berglund

So am I.
//magnus

PS. Got the exhaust now.. Will post more on that later.. Looks quite good.. but the headers have thin walls for use with the rotary.. Still it's 25 years warrenty..

//magnus

rotary emotions

25 years??? sounds good, I wonder if I could get 25 years of warranty on my tyres :-)
Seems the size I need might not be in production anymore...

Magnus Berglund

hmm.. the site even says lifetime guarantee... www.mazdarx7.co.uk

What size are you running?

//magnus

rotary emotions

I thought 255/45/15, but the guy says they don't make that!? It is 255/../15, but I'm going to check the "45" tomorrow, might be mistaken for something else...

Magnus Berglund

Back to the modelrotary..

Found these on ebay... apears that there are many who want them..

Magnus Berglund

Finally sent you the money!
I think you get my adress with that right?
//magnus

Andreas

Bart, Mike and Magnus: got all names, adresses, citys... everything complete and money received, tomorrow i'm going to the postoffice () and send the package to the three of you.

the above is because i must get up early instead of getting out @ 11:00 and the people @ the postoffice are like Porsches... so s-l-o-w...
