Newbie - Pleae HelpMe !! Trying To Fly My New Pico-Cub - Page 4

Clive Henry Jones · Jan 15, 2001, 04:39 AM

The first flight........I remember that!
You are a LUCKY bloke, having your wife and family pulling for you as they do. My missus thinks I am a bit tapped for disappearing on Sundays "Flying toys again"!

A quick tip given to me by the lads at JD Aerotech (Ask Joe and Don forum) is that when you fly towards yourself and the aircraft "drops" a wing, use the "stick" to "Prop up" the dropping wing.

In other words, If you see the wing on the left side of the approaching model lower than the one on the other side, move the rudder control to the left to "support" this lower wing.
Joe and Don also revealed another trick to help you get this "unconscious" response, and that is to practice with a cheap R/C car. Drive this towards yourself and you soon develop the feel for the correct input needed whilst minimising the damage to your wallet!

BTW, My PicoCub broke the fus just in front of the tailfeathers the other day, seems that making the pushrod exits in this area is a bad idea! Just sorta lifted up off the ground on a windy day, rolled on it's back and SNAP!
Moral of this story is to leave PC in car if the wind is anywhere over 5 MPH or so - or make sure it is properly tethered!

A few drops of epoxy and some strapping tape had her fixed in no time so no sad ending to this story!

Oh yeah, Leccyflier, I too have had "Buzzing" noises coming sporadically from the engine compartment since I fixed the engine and gearbox combo on. Will try the flat grubscrew tip (have lubricated the unit previuosly)- any idea of the size needed? - we have a big stores here in work with all the fasteners clearly labelled - I just want to spare me a bit of time in searching many trays for the correct size.

Thanks in anticipation,

Clive.

way to go on your first flight

astra turf really works well as a run way
the only trouble as soon as you get good weather the kids will be out playing cricket
on it

I tried 6 cells and it did fly but the take of run was really long and a little bit tricky.

The grubscrew story turns out to be a bit more complicated than I had thought- I "thought" it was a flat bottomed one- the supplied one in the gearbox had a pointy base.

In fact the one from my mate Kev's massive, extensively stocked flight box which we used is supposedly designed to bite into the shaft and has a ridge, rather than a flat base - it starts as a cone and then is hollow with an inverted cone shape. It is 3mm in diameter.

Kev said the plain pointy ones are useless for retaining gears on the shaft and sure enough it had stripped the hole before it tightened up enough. The new one is great. The lubrication on the bearings helped a lot and the gearbox is now much quieter.

Another good tip that Kev came up with was to staple the velcro battery retaining strap to the lite-ply sides of the battery compartment with ordinary office staples, rather than messing with epoxy - that worked a treat

cheers

Still have not had chance to get out for a second flight

Too busy with work

I have brought some bits and pieces though to strenghten up the landing gear and add struts.

For those interested, I have also found another excellent review at :

Jerry,
Thanks for the update....hope your job interview went well.
Read the article you cited...very interesting...almost ready to pick up the phone....Is that the same gearbox you bought?? The MPI 2.5:1?

I found out today my depth perception ain't the greatest. I was fling the Wingo in a park with 9 very tall light poles evenly distributed over the field. The plane was about 300' away and I was wanting to go around one of the poles...whoops, caught a wing and really got a nice spin. The Wingo recovered tho and flew on.
Good Luck with the Cub, we check every day....

Hoppy,

Thanks. Won't here about the interview until Friday. Went well though I think!

The gearbox I use is the one that you can buy with the Permax 400 motor i.e. 400L (2.3:1). It's just a nylon jobby. The one in the review seems to be made of a more substanstial alloy.

Jerry

jerrysimon · Jan 19, 2001, 05:51 PM

Well i did not get the job. Did not want it anyway

So I have charged up my battery and tommorrow will go and fly my plane for the second time at 7:00am.

A couple of questions for you Pico Cub owners. I have two Great Plane Cubs, one electric and one with floats with glow power. I'm getting rid of my electric powered Cub as well as all of my 05 size electric planes. I would like to replace the cub with a Speed 400 Cub so I can use my 8-cell RS nimh packs. How "scale" does a Pico Cub look. Does it look a bit cheesy or is it something you would bring to the field to stand up against built-up models? I have never seen one in person and it's hard to tell from the Multiplex web site. Another question. Is the wing shipped in two halves? I'm thinking of using less dihedral and installing ailerons instead of rudder control. I'd probably install the aileron servo in the wing, one for each aileron.

Danny Troy · Jan 19, 2001, 10:10 PM

Disregard my questions.....I just found my answer on another post....and also found out about the $35.00 Sureflite foam Cub...interesting

jerrysimon · Jan 20, 2001, 04:49 AM

Well by the time I got to the field it was 8:00am. God this hobby is good for early morning watching the sun rise.

It was cold. Flew like a dream but then I wanted some close passes so I could see her in action up close. Few in a couple of times about head hight it was great. Towards the end of the flight did it again but got confused with my up/down elevator. Went into the ground

Not too much damage just a broken propeller

I love this hobby

Jerry (needs lots more practise)

OK gang, Thinking caps on.
After checking the grubscrews supplied with the 'box, I found that they were the ones that Brian had described (Inverted cone).
I tightened these up expecting that the "buzzing" noise assosciated with this 'box would cease.
It didn't and the PC flew, but not as well as previously.
Any further ideas?
Clive.

leccyflyer · Jan 21, 2001, 06:52 PM

Have you also tried a bit of lubrication on the gearbox? When we cured the rattle we replaced the dodgy pointy grubscrew with the "inverted cone" one and lubricated what passes for bearings on the gearbox. That made a big difference to the noisy box - it could have been the lubrication, the grubscrew or both.

The other thought I had- before Kev pointed out that the grubscrew was wrong- was to file a flat on the shaft to make sure the grubscrews were doing their job and stopping the gear slipping on the shaft.

The other thing we investigated for the noise - which was loud and clattery -was the prop or gear catching on the cowl- it wasn't as it happens.

oops, best to keep high untill your thumbs
are used to the controls.

no buzzing the tower, that comes later

did my first loop this weekend, you should have seen the grin on my face.

I'm still not able to get rid of the gear box rattle as well.

also tried out some 7cell 1100 Nimh battery's great duration.
