Spotlight Review

"Take notice of assembly required"
I know this has been said before on reviews but I missed the part about assembly. This is a great controller but be prepared for at least a half hour of assembly before you can use it to launch. Don't do what I did when the box arrived and get your kids all excited for a launch. They will ask every few minutes how much longer it will take so we can shoot some rockets! Other than that............great product!

"almost great"
When I first picked up this item I was surprised that I had to put it together and I didn't have all the proper tools, such as a soldering iron. But after building it I realized that I should have just built my own for this price and have a better launcher to suit my needs. This product is great for mpr range and gets power to the igniter now!


Always follow the National Association of Rocketry Safety Code when flying your model rockets.
