Can anyone give me their thoughts on launching a LOC Graduator with an
Econojet G35-7?
The kit suggests G40-10 or G80-10 for G-class motors.
Thanks!

The G35-7 is quite a ride for the Grad.
The 7-sec delay is also probably better than the 10-sec delay
for the Grad on G40 or G80.
Here is a summary of the Grad on all the thrust curves I have
for 29 mm motors .

Graduators REALLY rock on an H238!
:)
It should be fine . I launched mine on a F 20 Econojet with no problem.

I used all of the kits recomended AT motors and had fantastic
results...The G40 & G80 were just finewith the 10 sec. delay..........NO
PROBLEMS! really nice flight with a T engine
Just don't use 5 min epoxy like I did...........after a few launches it
developes stress cracks along the epoxy filets.....I just re-poxed with
long cure..30min or longer and trashed my 5min stuff
Hope this helps...............Jay

I sure can't argue with your experience.
hmmm ...
At what altitude is your launch site ?
How much does your Grad weigh ?
The reason I ask is that Barbara has maybe 25-30 flights
( F--H ) on her Grad. It weighs in at 18 oz ( includes
a longer MMTube, extra CRing and a 3/4 inch T-Nylon Shock
Cord Anchor ).
A G40-7 is just about perfect for this config while a G40-10
is about 3-sec late ... ??? hmmm ??? ...
