    Looks like pre-orders can be made through Mile High RC. Makes me wish I had an airframe.... maybe I should change that???? I usually don't like being the test rabbit on a new product though...
    $660 shipped. Expected end of the month, shipping mid April.

    That's not such a bad price considering the alternative is 749.00 plus another 149.00 for mufflers.
    My GP76 fund me account is growing :).

    One thing I like doing is getting all the RC goodies first a bit here and a bit there. Then in the time it takes me to get all the goodies a new air frame will present itself :mario-banana:. That I just have to have of course :rolleyes:.

    Wanted to do a comparison of the 70cc class motors now that the specs are mostly out on the GP-76.
    The GP76 is only 0.213"/5.41mm Wider cap-cap, 0.19"/4.826mm Longer Mount-Hub, and 0.088lbs/40g Heavier (without muffs or ign) than the DA70. so less than 1/4" dimensionally and under 1/10lb heavier. Not bad GP, not bad at all!

    I'll update this as more info becomes available.

    All motors listed below have the same firewall mounting of 66mm H x 78mm L. All come with Genuine Walbros, and NGK CM6 plugs. Weight shown below is without muffs/ign.

    Engine: CAP-CAP dimension: Weight: Price: Mnt-Hub: Comes with the following:
    GP 76 St Plugs 10.826" 1650g/3.637lb $660 5.73" Muffs, V?Ign, ?Yr Warranty
    DA 70 St Plugs 10.613" 1610g/3.549lb $749 5.54" NO Muffs, 6.6V Ign, 3Yr Warranty
    RCGF 70 Ang Plugs 9.37" 1508g/3.325lb $499 5.65" Muffs, HV Ign, 2Yr Warranty

    Mile High RC shows plug dimension 250mm with caps.

    I hope this was educational and rewarding as it was for me!

    With factory numbers posted and props used I say this thing is going to be a BEAST. 25x8W 7140!!! That's insane. My DA70 turned it 6950 on a good day.
