-> I am the owner of a Concept 30 SE helicopter from Kyosho and now I li
-> know if there are others out there with the same model who have any
  Sure!, I own three concept 30 SRT's, A Concept 30 SRX, and a Concept
60 SR "Championship"
-> ST34H engine which I have heard is not so good, is this true? Should
-> i consider buying an OS engine instead?
  I do not have any experience with the st34H, all my birds have O.S.
The 30's are running O.S. 32F-H and run real well for and setting the
needles is a piece of cake compared to the three needle in the 60.
-> first time I had equipped it with a training gear consisting of two
-> cross-layed PVC tubes and that worked very well until...
 You could try a piece of 3/4 or 1 inch plywood cut into a 3 X 3 inch
square, drill 4 1/2 inch holes, (one in each side) about one inch deep.
 Place a half inch dowel rod in each hole and on the ends of the dowel
rods place some LARGE wiffle balls using cotter keys and washers to keep
them on the rods. The dowel rods will help absorb some of the scock from
those "firmer" landings and you will also be able to get a "feel" for
the sticks (if you need that) as your trainning gear will roll around
freely on the ground. A nice asphalt or concrete parking lot is really
great for that. Also, your dowel rods could extend beyond the rotor
blades, as mine do, which was real nice for a guy that I was teaching to
fly last year when he drifted into a chain link fence...no damage! The
trainning gear and the wiffle balls stopped the Heli before the rotor
blades went into the fence...
 You might also want to put a remote head lock for starting it, since
the trainning gear will make it hard to get to the glo plug with a
conventional glo starter, and after you shed the trainning gear you wont
have to be poking around under the craft to find the glo plug.
-> firmer landing and BAM the rotorblades hits the tailshaft.
 Rotor blades hit the tail boom? When you repaired the damage, did you
also put the hard dampers in the rotor head? These are the red ones,
and they will firm up the the rotor blades nicely. No more sagging
blades and they shouldn't hit the tail boom even on the hardest of
landings. Speaking of hard landings, you have equiped your heli with
auto rotation haven't you? If not, these are the first two things I
recommend to any one who buy's a new heli. Auto rotation, and hard
dampers on the feathering shaft's.
 Any questions, feel free to ask...
