test flights: lots of them, bottom line, flies like crap............

I cant believe how poor this flies. forward flight, okay but vastly different left aileron vs right right, very slow to turn left with allot of lag, right, rolls over nicely and turns 3 times faster,,,,,,,,,,,,. static hover is good and allot of fine tuning on the servo links to get this spot on. very slow on left turn, fast on right aileron.

if I fly in reverse this is where it goes totally pear shaped, heli starts to roll to the right, aileron left to counter response is very poor, wont respond, several near misses. I'm not talking fast flight here just gently bringing it back toward me. stock is fine as doing this. this was a real eye opener, something wierd is going on with the cyclic on the head for sure...........

on spool up and initial hover it can get into a wobble then stablises.

Gains set according to the instructions and fine tuned the tail and filter settings. tails was twitchy at 180 and improved as the gain value was bought back to around 150. definite improvement with tweaking the gains

seems to have allot of pitch, collar is set correctlyin the recess on the driveshaft, moved the collar to the top of the recess notch to takes some pitch off, still seems excessive. might just try locking it higher up.

been right through this several times. Drive shaft bearings and frame are new, servos good, was flying fine in stock form.

observations are - blade grip feathering...Continue Reading

Blade comparision, the microheli blade is a proper symmetrical cp type blade where the stock unit is a typical assymetric profile to generate lift and has the pitch set into the blade root.

The rotor head is a smaller diameter, the blade grips are longer by 10mm versus stock, but the blades are shorter, 150mm vs 185mm stock. Taking into account the difference in blade grip length the rotor dia is 50mm less than stock.

The stock canopy grommets are a right pain in the rear, tend to pull through the canopy and tear with use and fiddly to get on, ive been flying with out the grommets but the canopy vibrates on the mounting pins.....

Microheli grommets have a larger flange and outer diameter to prevent pull through, and the canopy mount pin hole is
larger, rubber is noticably harder. Fit is still tight, and a bit of silicone grease works wonders. 4 in the pack also.
