Hey guys, I'm looking to try some of the quest q-jet motors for the first time in 18mm size. What one would be comparable to the old estes c5-3? Thank you for any replies. Bill
Can they be ignited easily in a 2 motor cluster?
Speaking for only myself, I've had difficulties trying to ignite two in a cluster. The problem could be the user, the ignitors (I think I tried both stock and my own), the motors, or some combination thereof. Those attempts were August 2018 and August 2019 - I can't remember the details.Ok thank you for the excellent reply! I loved the c5-3 motor and wish it still was around! I've had special situations where they worked very well so maybe I can use the q-jet. Can they be ignited easily in a 2 motor cluster?
Now that we know the application I would tend to agree - try a pair of C6-3s. Then maybe go for C12-4s....though I’d be a little concerned about the health of the styrofoam gliders given the progressive thrust curve of both the C12 and D16.
I still have a few C5-3s that I acquired shortly after becoming a BAR, thanks to someone who had his Dad’s hobby shop in the basement of the house. In general they have been fun motors, but the last time I tried to fly one the LCO noted that they have a reputation for CATOing and sure enough, one blew up my Fat Boy. I probably still have a dozen or so...and of course now am more reluctant to fly them than I was before that.
And that means, among other things, heavy enough wires out to the pad. Even with a good strong battery, long skinny wires can do you in. It should be at least lamp cord, not the lightweight wire found on entry level controllers.-Make sure the launch system can deliver enough current for both motors
That makes a certain amount of sense, as the large initial thrust spike implies a corresponding pressure spike.[T]he last time I tried to fly one the LCO noted that they have a reputation for CATOing...
Well yesterday I launched my stretched deuce with two space shuttles with two Quest Q-jet d16-6 motors! Very successful clustered launch with great height and great shuttle glides! I should have used a shorter delay but it was fine!
On my Deuce I did just fine with standard Estes starters without a clip whip. Although the longer leads on the Qjet starts certainly adds some nice extra slack.Pweesh! Good discription! What i did like about the ignitors is that on the Deuce I did not need to use a clip whip! The leads were long enough without it!
s often quite a bit more than 12% better.
