[P4cm4n2000]

Here are some photo update of simple repair progress of a bro's balsa plane Vision EP, just to share with folks who may need this info..... and progress update:

Plane's spec avail here:

Here goes!

Damage level: 20%
Damage area: motor mount came out, front fuselarge damaged.
Cause: Direct head dived onto pavement, due to either glitch or no control totally. reason not known exactly.

Progress:
as shown in pic area of damage... Motor mount in pic already epoxied back in place.

:l :l :l


trimmed away unwanted areas to make way for new balsa wall.

[P4cm4n2000]

Balsa wall for front fuselarge trimmed to size, then using 3M CA (S$6 from JetHobby) to tag only on selected points to hold new balsa wall in place, remaining area of contact smeared with PVA (Selley's S$5.60).

[P4cm4n2000]

Reinforce motor mount with extra balsa underneath, coated with PVA, then using cable tie to firmly secure entire mount onto main ply joint on fuselarge.
Seems manufacturer's design where motor mount is only secured on two points seems very weak.

again, left plane next to windows facing Punggol Field walk field to dry...keke....

Tonite:
just almost completed repair to fuselarge front side walls.
then realised need more enforcements to the undercarridge mount
as it depends only on the two side walls of the fuselarge.

Further added inside walls of weak joins with PVA to close gaps, then clamp to dry.

hope to complete repair so our bro can fly coming Sat...keke...

Final finishing to acheive as in blue plane.

some update for the repair,
strengthen side walls using balsa woods, mixture of using CA glue to tag-in-place, then use PVA to spread over middle surfaces.

the quick-release clamp I bought from Daiso (IMM 4th floor) proved very usefull when it comes to such need.

[P4cm4n2000]

Fixed back the wheel mountings,
more pics of overall simple repair work, not professional yet due to time constrain, but workable..keke...

Warps:
======
As you can see , tail portion is slightly warped, hmm...need to maybe add ice-screen stick to level both left & right portion of the elevators.

Motor Mount
===========
finally added another coat of epoxy, better to strength using cable ties too.
Should you buy a balsa kit, do check the mounts ensure its really strength,
though manufacturer may not "add" too much woods around this area.
hey, landing skill varies bro...keke...

Right wing broken "rip"
=====================
glued back the rip on mid-right wing.
then using some old monocoat 16years ago, (pardon me Temmanis) cos those were closest color I've got at moment...

[temannis]

thank you bro! no problem with the different in color. As long as it can fly again. I am very happy already.
