Building instructions for the ultimate 120 bipe

The instsructions are the worst ive ever seen in an arf. The pictures they show arnt even the same as what the plane is. What can i do? ive put together arfs before but never anything of this scale. Also i was thinking of putting the o.s 110 fs-a in this plane do you think that will power it adequatly? i also was wondering what size servos would best fit this plane. thanks, travis

Have a look on rcuniverse website for your aeroplane, there is probably a build thread on there, a 110 fourdtroke will be fine, use the best servos you can afford, i like to use hitec 645 servos, 9kg pull, suitable up to 70inch wingspan models

I have a lucky star 40 rc airplane. The cover is full or wrinkles. how do I resolve this problem?

You need a covering iron. They are used to put the covering on the plane. Lower heat to activate the glue to stick it to the wood around the edges and then higher heat to shrink the covering before pressing it down in the middle.

Ive just put a brand new belt on my machine and its slipped of during the first wash and it has not even had a spin yet,how can i solve this problem

Assuming you put the right size belt on, then the only problem that could be left would be:
A frozen pump from something like a small chain getting in it.
The pulleys not all being aligned on the same plane for some reason.
The tensioner spring not pushing the idler pulley on the belt correctly.
A frozen idler pulley.
The belt routed wrong and rubbing on something.

Hard time getting car started..

The starter test at auto shops arnt always correct. In your car you have a load on the motor the auto shop doesnt. You could have barrings seizing up or a bad solinoid. Check the wires then get a starter ive seen the auto shops take people for rides. Ask people up there that have been doing the test for awhile they can hear it and tell you it will be bad before the out come and it will show good.But it is bad.

Mine stopped taking pictures and showed a generic partrait icon where my new photos should be (in camera album). This was after I removed my removable disk the day before and not powering down the phone before i put it back in. Hope this helps.
