    Stock 2007 RXT, SC wheel change

    Assuming no other modifications to my stock RXT215, can anyone tell me what benefit if any would be realized by replacing the original SC wheel, which I think is a 4.5 boost with a 7.5 boost wheel?

    Minor mods that I am considering while maintaining reliability:

    - 7.5 SC wheel, steel washers, ceramic bearings
    - Riva intake grate
    - 2 degree wedge

    Welcome to the forum... The more boost you have the more fun you will have. Benefits? Major power

    If your going to change wheels get a Riva S3 bolt it in and go.
    Best bang for the buck, ran a t that way all year last year, ran great and better fuel econemy as well.

    If you are just dropping in a fan, as they say, you should do the Greenwheel. You will notice the difference in idle to WOT and part throttle to WOT acceleration. If you're not careful your arms will get longer

    Mods to my 07 RXT are as follows,... Green wheel, steel washers, ceramic bearings and Riva toploader grate. Modded top speed results were approx 1 mph SLOWER over stock but acceleration was a huge difference! A 14/19 prop then got me 66.9 mph GPS at 2200 ft alt. in fresh [email protected] 78oo rpms.

    Cheers

    Chris.

    you've got to upgrade fuel to go with the s3. The greenwheel/riva gen II/rotax are the only "bolt ons" (when you have to touch fuel components, i no longer consider it a bolt on)
