here's a pic if you want. It's good for small-medium hands like mine.
Also if you'd prefer to skip the Speed Build kit, you can get Ross foam board from amazon, and a craft knife. that way you can save money and foam.
These are "ok". I personally don't like these mini glue guns because I always run out of glue when I'm trying to do a LONG run of glue for things like the wings and spars - for example, doing the Versa Wing, I can go through 1/2 a glue stick gluing the front edge, back edge, AND the spar together on a full size glue gun. These mini stick guns leave me pushing a full stick through, and that's if it's brand new, having just loaded it in. If I'm halfway through a stick, I'll run out and do a panic moment trying to load a stick in while the glue is cooling, and losing its adherence.
I've had an Adtech 80, which I bought at Jo-Ann Fabrics on a 60% off coupon; they were better due to the size of the glue gun and the full size glue sticks, and they came with interchangeable tips for narrow or fan application of glue. Truthfully, I never changed out the tips on the gun once I'd had the regular tip screwed on, but the option was there. I didn't like it as much as the one I'm going to recommend, though, because the trigger on it felt flimsy and I felt like i had to do a bunch of pulls on it to get glue to come out.
4 years ago, I bought this:
Dewalt's Ceramic glue gun. This thing has been my workhorse. I have built over 400 chuck gliders and probably 30-40 different FT planes with it, and it works just as well as the first day I bought it. Cost me $30, and I think it was one of the best purchases I've made for this hobby. Comes in a little cheaper than the Adtech 200, and I've gotten so many comments on how it's a "serious" glue gun by the crafters and Makers who have seen me use it (and really, it IS a serious glue gun).
Now, getting on to the plane - if you want to buy the starter package, it's actually not a bad deal, especially if you:
1) Do not have a transmitter, glue gun, charger, or tools
2) Don't know what to buy that will work.
That was the initial purpose of FliteTest coming out with these speed build kits and power packs; it keeps things simple, and if you buy the recommended power pack for your plane, you are getting electronics that WILL work with the plane you're building. They also stand behind their products; if you buy a power pack and a servo's bad, or the motor or ESC is bad out of the package, they'll generally replace it without an issue. Buying from Amazon or Banggood, you may be buying lower quality goods, or have to wait months before you get all of the parts you need (especially right now, with an electronics shortage going on due to COVID and items out of China and Hong Kong being stopped from shipping).
If you just want cheap, you can certainly find stuff for cheaper than what most people are recommending here for electronics. But, you take a risk on the electronics not working or not being able to do what you want. I bought some CHEAP servos from Amazon at $13, and half of them had brownouts as soon as I plugged them in to a receiver. No matter what receiver, what ESC, 5 out of the 10 servos I got had problems. If I'd spent $3 more for the name brand servos that gave the same quantity of servos, I would have ended up with servos that worked. But I had to try and go cheap...Cheaper isn't always better.
