Yes another question

I don't know if they will work together, they look like they wil. Check these out. I'm sure someone knows if they will work together. I use the throttle back plate and like it. It would work better on a servo I think. On a three line bellcrank it has it's problems to over come. I plan to put mine on a 2.4 servo and run two lines.

Throttle backplate



Engine



Muffler

The throttle rings work ok but the rear-mounted throttle seems to work better (cannot be used in conjunction with SPI cylinder/piston setup).

Our throttle rings will not fit engines with die-cast crankcases.

Rear throttle and muffler can be used together.

Thanks for that, Ebay here I come. Trouble is I need to keep the intergrated tank.

Cheers.

Maybe this will work?

Bernie?

I have one of each r/c option, and they both work a-treat.

Both are available from Bernie and they're each cheaper from Bernie than that one on e-bay. Both r/c options work absolutely faultlessly with one 6g servo. If you need more than a 6g servo on your r/c Bee then you have other problems which you ought to sort out.

Hi,


If you are using Cox Surestart, or any other non-SPI type of cox engine, try Bernie's throttle back plate, or Dragonfly type of throttle muffler. check this out for the throttle muffler performance :

I'm building Fournier recently too, just that I can't find liteply locally .
I missed my my first Fournier built about 12 years ago, from pull out plan ( Radio Modeller 1992 Oct ) I'm trying to build another one , and the plan can be download at
http://www.outerzone.co.uk/plan_details.asp?ID=2312

is that the one you are building now?

No I got confused it this Ogar I'm building.http://www.outerzone.co.uk/images/thumbs/plans/3915.jpg. However, I must get a copy of that Fournier plan. It's very tempting.

Cheers
