Re: How to assemble 049 engine?
Well then you have to work logical
Step one why doesn't it rotate
Step two try spring again

Re: How to assemble 049 engine?
okey
lets make it easy
if the engine doesnt turn over (the prop)
remove the back
and see if the crank moves if you try to rock it
if the crank moves it means your piston is stuck
of the crank doesnt move it means the crank is stuck
for a stuck piston
heat the engine to 60-70C
and carfully try to move the prop
the temperature melts the old oil and frees up the engine
now use wd40 to clean up the old oil (just spray it ontop of the piston)
for a stuck crank
remove the piston and cylinder
find a bolt that fits inside the screwhole of the prop
place the whole engine (prop side up)
on a peace of wood and then give the screw a few taps with a hammer
this seperates the drive plate from the crank
do this untill the crank drops out or untill it freely rotates
if its free and it rotates again
assemble it and then come back
(sorry for the bad grammas I is dutch)

Re: How to assemble 049 engine?
I figured it out. Your supposed to let go of the prop when the grey cap catches the spring
You turn it in a half and let go
Now I need to figure out how to screw the engine on the mount

Weird because the screws won’t fit in. Any reason for this?

Re: How to assemble 049 engine?
The screws fit. You need to obtain a proper fitting screwdriver. You also should put on a pair of gloves. The screws are self tappers into plastic, they're not going to thread in like a machine screw. They're going to require force and a good bit. Therefore, if you slip and your wearing gloves like I suggested, you won't put the screwdriver through your hand. This heli uses a Sure Start backplate ( Gray) which is mounted to a black mount. the black mount utilizes it's top holes into the rotor assembly. The Sure Start backplate utilizes it's top holes into the black mount with longer screws. Then the two smaller screws again from the lower holes in the Sure Start backplate into the black mount on the rotor assembly.
To simplify, you have two short screws, two long screws, two short screws. After assembly, insure that the screws have drawn all sections together. Self tapping screws have a tendency to push apart rather than draw together. This may require you to unscrew all the way and run the screw back in. Spin the rotor assembly and insure that the seams of all mating surfaces are closed and touching one another.

Can you post some pictures and explain exactly what issue you are having with the screws?
It takes a village

Re: How to assemble 049 engine?
Loosen all the screws to the point that they're just started into the plastic. You should have some wiggle and get the problematic middle screws started. If need be, the black spacer under the gray Sure Start mount is only a spacer and if need be the middle holes can be opened up to allow a little clearance. The middle screw, the long ones are retained and captured in the rotor assembly.

I am just saying sometimes it takes more than one of us to help. Different people have different perspectives and “see” different things about the problem that maybe others do not see.
