Welcome to the wonderful world of Micro's Jeremy;
Actually there are several things you'll want to do with your new starter set to increase your LPB Micro flying enjoyment:
First the Saturn-V is almost always unstable out of the bag even the ones with larger fins. We've come to expect this state and have an easy and quick fix for this great little model. She just needs some very small clear triangles added above the existing fins to make it fly very well. see Photo below. I used the clear window material from the starter set for these added fin additions with a little CA.
With any wind at all the tiny shuttle orbiter will corkscrew in flight, on dead calm days it flys OK.
As ScrapDaddy mentioned the UFO flys well but only gets about 25feet on a MMX-II motor.
The rest fly very well particulally the Tomahawk ALCM and the 3F&NC Raw Fusion & Vector models. That darn SR-71 always seems to want to lawndart for me LOL! but flys OK. Proper preperation of the streamer is very critical with the SR-71.
A couple things about prepping these models:
1) The LPBs (Little Plastic Bricks) with piston streamer retainers need some attention before launch.
PLEASE NOTE: The mylar Foil Streamer WILL NOT unwrap from the stem if left rolled as they come from the factory.
* Unwrap them completely to the attachment tape.
* Talc Baby powder both side very well.
* Fold the streamer in half, then half again and again until the streamer will make a single wrap around the piston rod. Slide into the closed postions and insert a motor.
* snap-lock motor mounts have a tendency to popoff is not secured with a small piece of 1/4" masking tape.
* On a few model (Space Freighter and Shuttle) their Streamer are attached to very short shockcords. Over time I've learned a tiny piece of FPrecovery wadding with greatly extend the usable life of these recovery systems. used as they are they last only 3 to 5 flights.
Controllers: If you have either the OLD style Silo Launcher or the Newer Pistol grip controller both can be used directly as they come on a 12v battery with an exterior drop clip and alligator connector that can be purchased from Quest or made with a 9v battery clip or spent 9v battery. I've been using these controllers on 12V gel-cell batteries for the last 10 year or so without a single problem with either type controller. (See Photo)
If you must for the time being use 9volt batteries. it is STRONGLY suggested the only type to use are 9v energizer Lithium 9v's. They will give you at least 15 launches were the best Duracell 9volt batteries only lasted about 5. That is with the old style Plug type igniters. I haven't done another test with the new micro Q2 bare nichrome igniters but I can't see there being that much difference.
It is also extremely important that the nichrome igniter wire is touching the propellant inside the nozzle. take care to see the model sets on the igniter well.
Hope these suggestions, photos and tips help.
