Hello,
I am sorry about this little delay on my reply, as I was away.
Glad to see that someone also still fly the Race Rat model.
It is a really great speed model when slightly modified to the
glow engine, especially if also changed wing profile.
I tried this model with various motor combinations, and the
best I like so far is with an OS .32 SX and 8X7 APC prop,
it fly like rocket !
The original plastic fuselage is of a bad quality material,
and it can be very fragile during the winter, and during the summer
it is just too soft to be safe, especially the rear side where is
horizontal stabilizer.
I have the mold for the Race Rat fuselage, but it is not a direct
replacement.
It is modified for glow engines, and there would be hard to
modify it back to the electric motor, as the front of the fuselage
is altered.
Also there is no anymore air inlets and outlets for electric
motor cooling, as they are completely useless for the glow version.
I don't know what is the weight of the each part, as I never weighted
them.
This is why on the one verisin is label 'ultra brick', one of my friend made
this joke and I simply printed it to the model ...
But, the model is not heavy, with engine off it even glides almost like a
glider, and because of this I never bordered myself about the weight.
The wings are of styro-balsa, or of another model styro-abachi, and
there is 80g glass fiber cloth between them.
The fuselage is of glass-carbon-kevlar construction.
Best regards,
Kristijan Kljucaric
