New guy here, been flying a couple of months and can't get enough. Want to say thanks 1rst for the tremendous amount of info here. Now i have a question, just finished the E-450 upgrade, esc, receiver, etc... Love the added power and response, sounds awesome too. However, when i throttle up it climbs steeply, have to hold stick forward or it will fly straight up. slower flying no problem at all. CG is good. Is this normal?

try adjusting the horn position on the servos to a more "down nose" position. usually one "click" does it.

Initially all control surfaces should be flat.
Check your CG. Doesn't matter what motor you put in it, CG is the same.
[CG:2.25" back from leading edge]
This is your absolute FIRST step.
Motors have lift and torque effects. That's why the stock motor is pointed down and right. If you removed that tilt.....put it back. This effect is most noticeable on throttle up as you indicate.
If you did not remove the tilt....you may need more down to counter the extra lift from the more powerful motor. Try some washers or whatever you need to adjust. Just a little at a time and test.
The Cub was not designed to be a rocket. Problems do crop up when you over power it's design specs. That's normal. People tend to ignore that little fact.
Make sure your wing saddle is not messed up and the wing is positioned properly.

Had issues with the wife's cub wanting to do the serious climb.
ended up putting 3 turns in on the elevator clevis before it went away.

Had issues with the wife's cub wanting to do the serious climb. ended up putting 3 turns in on the elevator clevis before it went away. That's trimming the plane. Initially (for high wing planes) all surfaces to be flat. Use a ruler edge or something to be sure. TX trims should be neutral. Fly and trim as necessary with the TX. If you want, or the TX trim gets to it's limits, you can then mechanically re-trim (control horn clevis) and put the TX trim back to neutral. |

Yessir, we were max'd out on the Tx trim. Hence the mechanical trim.

I find that simply throttle down works well too. If into wind I elevate nose down a bit too. That rocking up and then up and up eventually can help u lose control. And if your too low. The stall will smash your cowl to PC' s on the ground and leave you propless before any elevation. Tough plane though... I'm impressed.

I initially thought the plane would.nose up because of the wind. What is considered too much wind for this plane? Over 10?

Depends on your skill level. Little to no breeze when learning. 5-10 mph when you get better. Nothing over 15 mph since the cub weighs so little.

according to the manual the hz cub is rated for 7 mph wind, but like iandhunt said depends on your skill level I kind of like flying in some wind I think I flew in winds as high as 18 mph
its no party but what a ride.

If trimmed properly with a good CG a plane is designed to climb at some rate of WIND SPEED. In still air, this is controlled by the throttle, full throttle~climb, half throttle~neutral, less throttle~descend.
The elevator is only for fine control, or tricks.
If flying into the wind you can have almost no ground speed, but lots of wind speed so still be climbing. Going downwind you can have a LOT of ground speed and still be dropping. You can have such little wind speed that turning can make you stall and drop.
When people upgrade they often screw up the CG, the thrust line, or just don't know, or forget, that speed makes it climb. That's normal.

Hello all, new into this forum but have to say due to a toy helo I reveived on Christmas I'm now bz deep into this. I have the HZSC, 2 Champs, gave away a Stratos and have a AXN in the mail. Iv'e crashed and smashed every single one of them and subsequently built a small horde of spare parts, equipment and supplies. It's more addictive than ex-lax in a cheese factory. I do not mind crashing as much as I should because I find the repairs and reading up to be as fun as the flights. I have actually learned to fly during the construction/destruction and find the Champs immensely entertaining. I've flown Cessnas and Cherokees, P-3's and G-1's during my Navy days and these lil "toys" are more challenging than a spectator could know. BTW, I cracked my Apprentice in half on her maiden. Repaired her and gonna try again. I know your'e thinking "more money than sense" but I'm soon gonna dive into FPV before the Feds find a way to shut it down. southern Maryland, retired Navy, still in aviation etc etc

I'd say that's a somewhat accurate definition of RC pilots, although the 'more money' part isn't generally valid across the group. ;D It takes a pilot with RC experience to fully appreciate how difficult this sport is to learn. Welcome to RC flying. There does come a time when you go home without having broken anything. |

Hello, I'm in Lexington Park. Found out quickly how limited large areas of land are around here. I go to the park on Willows early when no one is there yet. I'm aware of the local club but I am assuming new guys with foamies are probably met with disdain so I don't bother them. The cub is small enough to park fly but beginning to wonder about the apprentice.
