Engine selection for H9 Beaver 30cc

    Nick, I never did get a ride in a Beaver while in Alaska :( but I like the solid feeling of flying this bird. The 30cc engine is powerful enough so I'm glad I didn't go with my DLE35RA. I am swinging an 18-6 but might change to an 18-8 if I ever tach this bird and see if I can over rev it with the 18-6.

    I watched the videos and still can't find out why it turned so hard on take off. Maybe the second take-off was because the left wheel was thinking of coming off...and yes I filed a flat spot and I thought I used RED locktite but I guess I didn't.

    At full throttle in the air, does the plane pull to that side? As in maybe the trust angle is off?
    Could have had one wheel on the axel/or pinched too tight? Might just need to be on the rudder more
    I haven't used red locktite in a very long time. Blue is the way to go!

    Going from low to high throttle doesn't have any effect other than a change in the angle of attack :) I'm going to move the wheel a bit further out from the strut - I'm using 6" Dubro wheels. I keep forgetting to buy Blue Loctite - maybe next time I'm in Wally World....
