On a small field (like a football or baseball field) with low winds, C11-3 engine gives a very impressive takeoff and moderate height flight.If you have a much bigger field, D12-3 gives more altitude.

Have reviewed previous answers. We tried the D size engine. Low clouds that day. Rocket penetrated them, then went out of sight. Did come down about 200 feet from launch.

The D size rocket engine from Estes is my favorite. The C works well too, but the rockets does not go up as far; that's what I use on breezey days so I d't loose my rocket!

You can use these for the first launch for both rockets in the kit. It says you can use a b4-2 for the amazon for the first flight but you can use the A8-3 for both the amazon and the crossfire that come in that kit. They have the same physical size but the A8-3 is the least powerful. I would suggest a pack of the a8-3 and a pack of B4 engines and use the A8-3 for the first flight in both until you get an idea of how much space you need. Low power motors like an a8-3 are also good to have around if there is any wind even if you have lots of space so you are less likely to lose a rocket. For example I live in a suburb and in a soccer field sized park I have never used an engine larger than a "B" size as I just don't have the space. In the case of the kit you mentioned the amazon page has the info you need: "Requires an Estes Engine Both rockets require a specialized Estes engine to launch. For the Amazon, Estes recommends a B4-2 engine for your first flight. The rocket is also compatible with other Estes engines, including the B4-4, B6-2, B6-4, C6-3, and C6-5. For the Crossfire, Estes recommends the A8-3 for first flight, and the B4-4, B6-4, C6-5, and C6-7 for more advanced launching. "

You need to run a dual mass with this kit. Right now this combined with the dmf032 which should show up as "people also bought this item, on this page" most of the solid clutch/flywheel kits aren't for a 240mm you can get ripped off. This was the best priced combo I found, OE replacement and 1/3 of the price I could get it through VW. I had a 337 which mechanically is identical to the 20th. The flywheel is on sale even cheaper than when I purchased! Double this price anywhere else.

Well... It will definitely go soaring out, providing you point the rocket up, but the odds of getting the rocket back are slim to none. Even a light breeze or angle will send it out, with no way for it to fall back down into your 4x4 open area. But taking it to the park would be a lot of fun.Hope this helps.MM

In order to launch the rocket, you will need the follow. You will need a battery for the launch ignition system. - It uses a single 9v battery. Rocket engines - You can use a8-3 for the Crossfire, a B4-2 for the Amazon (larger rocket), and move up to something more powerful later. The engine codes work like this (Impulse)(Thrust)-(Recovery charge delay). Recovery wadding - This is a flame resistant paper that you stuff into the rocket. It protects the parachutes from the recovery charge that fires after the engine burns out. To build the rockets themselves, which come unfinished. Scissors, a ruler, sandpaper (for the wooden fins, and finishing), carpenters glue, modelling knife (like an X-acto), masking tape, some plastic cement. The small rocket is actually unpainted, and you'll need some spraypaint to finish it. You can also get some clear coat to seal the paint on the rocket afterwards.

We fixed our rockets with duct tape. Hope that helps. Signed - Another user.

You will need an engine pack like this: Estes A8-3 Engine Pack (3-Each)The 3 engine pack will be good for 3 launches and also comes with plugs (to hold the engine in place) and ignitors to hook up to the launch controller. Lastly, you will need a few sheets of wadding to protect the parachute from getting scorched by the engine for each launch. My engine pack came with a few sheets.That pack is great for a first couple of launches as it will send up this model rocket around 200 feet. When you are feeling more adventurous, try a B4-4 pack or C6-5. Those will launch the rocket much higher.

I'm afraid I don't know. I bought the kit as a gift for grandson-in-law to have fun with our youngest great-grandson. We got similar kit for three of our grandsons and only know that it launched the rocket beautifully.

Recovery method is parachute. Great rocket. Painted it pumpkin orange and black. Wings give it a cool effect at take off...like slow motion then gone!

It came stock with a spreadbore quadrajet which is a great carburetor. Small primaries for excellent cruising fuel economy and huge secondaries for building lots of high end horsepower. A spread bore Holley is the next best or best depending on the cam and intake manifold. I do like vacuum operated secondaries, electric choke. Mechanical secondaries require a double pumper so that the engine won't stall on rapid throttle changes do to fuel starvation. Another option is a four barrel Holley throttle body fuel injection setup

Any, but make sure it is made for aerial craft, and can support quads. I suggest the Turnigy 9x. Good luck!

The launch system (the button apparatus and wiring...they're yellow in the picture) don't work. You need to get replacements or have your own if you want these rockets to launch!

Estes makes a rocket specially designed to launch an egg. Check that one out.

A MegaSquirt 1 can do launch control if it has the appropriate modifications added. This can take the form of a spark cut that can help build boost, although this is not the same as a full on, rally style antilag setup. Matt DIYAutoTune

Your best bet is the #1989 Flemish dyna flight string. It is what the manufacturer tests with and gets the best arrow speeds

Double A Batteries (4 of them for the 2.4Ghz remote and 4 for the receiver pack in the car) and Nitro fuel (20 to 33%). Traxxas brand fuel is good, and if you buy 20%, I think it's easier to tune the engine. If it's below 50 degrees outside, then have your son wait until it's warmer to break it in. Just my opinion.
