i took my hangar 9 super stick out again last night and im having a little trouble i had a 12 x 8 prop on it (.61 os) and when i went to take off it dug in the ground and wouldnt work so i put on a 11x7 (was this ok?) then i didnt think it was going to ever get off the ground it took the whole 300 yards or better runway i have mowed! but when i finally got in the air and timmed it out it kept wanting to nose dive i adjusted the trim all the way and it still kept noseing down ! i adjusted the cg and it was perfect according to the manuel but it sure seems nose heavy in flight if it was nose heavy would it cause the problem taking off? i dont know what to do because i dont know how much more weight to add to the rear since it balances so good!! help!!

11x7 is too small for a 60 sized engine. If the 12x8 is hitting the ground you can put larger wheels on the plane to give you a bit more ground cleanance. Also, bigger wheels will make it a bit easier to get through the grass at your field

I will make a guess or two. If its a 60 size plane (you didn't say). I would think that the 11x7 is too small. I would try about a 14x7 or maybe 13x8. I don't have the specs on the plane but its a 40 size with a 60 class engine it may be nose heavy. Either way the ruff CG should be about 1/3 of the way back from the leading edge of the wing. About where the wing is the thickest. If you do need more weight to the rear you can allways move the battery back further instaed of adding other weight. Good luck, mxerman

If you ran out of trim simply adjust the pushrod length by turning the clevis on one end. If the plane is nose heavy and you adjust the pushrod/trim for level flight then you may be in big trouble inverted. Get the balance right first.

i think my trouble is in the balance of my plane by the way it flys, but i dont know what to do because the balance is correct on the stand i know its always been said on here that a tail heavy plane doesnt fly very long but im thinking about just adding a little weight at a time to see if it will help, i already have the battery all the way back

those planes run tale heavy from the get go.i moved my engine way out onto the rail to get it to balance and keep from adding any more weight.i don't know why the prop was hitting the ground unless you had small wheels on it i had 2 1/2 wheels.i run a 12/8 to 13/8 prop on mine and don't have any problems with prop hitting the ground.i cut lightning holes in my rudder and horizontal stabilizer to lighten up the tale some that worked pretty well.
