Most of the Dynastar kits, including the Rip Roar, are built to be lightweight using balsa fins and thin wall tubing. The philosophy is similar to the Launch Pad's: Build mid power kits that are light for maximum performance using smaller 24mm engines.I like the Lil Augie for its unique design, the ripstop nylon chute the basswood fins . The only thing I dont like about the Riproar is the balsa fins. I can scratch build one similar to the RR but with custom basswood fins for under $40 but I need to decide whether to scratch build or kit? Hmmm??? The Augi's diameter is listed at 2.75". Is this an exclusive Semroc size?
You could use the kit and paper the fins. The kit has a proven track record with the balsa, paper makes them significantly stronger if that makes you feel better (as it would me) and adds very little weight.The only thing I dont like about the Riproar is the balsa fins.
I've been experimenting with these fuses https://www.skylighter.com/collections/firework-fuse I have the fastest 4 speeds (about .3 sec/ft to 10 sec/ft). They light BP motors directly and will light composites by dipping the end in your favorite pyrogen about 1". Wrap the part inside the motor but below the pyrogen with masking tape to prevent ignition of the bottom of the grain.Just throwing some thoughts out here: Instead of pyrogen coated igniters, would a quick burning safety fuse work just as well, if not better? One end wedged into the BP motor nozzle and the other end going through the bleed hole in the ejection well and directly contacting the delay element. Might reduce the delay gap and improve reliability. I know AT makes 24mm F reloads with a 3 second delay.
Capt, feel like experimenting? Thought/comments?
https://v-serv.com/usr/kits/hi-test2225.htm I just saw this in another thread thats sort of the same as this one and I would like to know if this company is still in business.
None of your videos are viewable.he primary aim of my experiments is to replace Thermalite for airstarting outboard motors in clusters. I used fuses to light 4 motors at the last Camden launch.
38/2G motor lit with 4-5 sec/ft fuse. About 7" long.
Can you give any personal insights on US Rockets kits? I did enough research to find out materials used like ply fins but that's about it.
Try now. For some reason they didn't publish.None of your videos are viewable.
They all say Unavailable
I bought the Two The Limit kit from Apogee last year. My observations/opinions are based on that particular kit.Fattbank64, Can you give any personal insites on US Rockets kits? I did enough research to find out materials used like ply fins but thats about it.
I dry fit booster and sustainer fins and there was neither a straight edge nor proper alignment. I showed the fin configuration to a friend and he said, "You paid money for that?" He does woodworking on the side and he figured out a method to get each fin in alignment.
Second, instructions are nth generation photocopies with half-printed letters, cutoff words, and incomplete sentences.
Don't, it's just the information I asked for.I apologize for the long winded response.
