To: Robert DeHate at Animal Motor Works Tim Van Milligan at Apogee Rockets Tim Lehr at Wildman Rockets Christopher Short at Chris' Rocket Supplies Gentlemen: Have any of you received engines from Cesaroni since 01Jan24? In the last six months? or, when did you last...

I would like information about an out-of-production kit from Public Missiles - the Tempest. Would like to know length, diameter, motor mount size, airframe - I think it is Quantum tubing- fin material. What was the retail price? I have sent an e-mail to LOC/PML asking the same questions, but...

Picture from my window. I think it is a Lamborghini, but I don't know what year or model. Bob in Phoenix

Have any of you built the Rocketman Showtime Kit? How did the build go? Did you make it longer? Turn the fins around? Can you please post pictures? A Rocksim file would be handy too. Thank you. Bob in Phoenix

I am looking for instructions for the AAA Model Aviation Fuels Cherokee G kit. I have checked Ninfinger, Jim Z, Ye Olde, and have not yet found any. Can anyone please help? Thank you. Bob in Phoenix

I am looking for a rocket video. I saw this some time ago on cable tv. Here are the clues. The rocket appears to be a full-scale Nike Smoke. The body is yellow, not white. The crew had the bird vertical on its tower when the parachute deployed ON THE GROUND!. I think this occurred at an...

I am building a PML Pterodactyl Jr. Four inch diameter, Quantum tube pre-slotted, G-10 fins, 38 mm engine mount, all very nice. The kit comes with a piston ejection system. But I like baffles. So finally, a question: Should I use the piston ejection system, or should I install my favorite...

Today I attended the Superstition Spacemodeling Society, NAR Section 506, launch at our Kofa site. I flew a LOC Precision Warlock using a CTI J285. I made the bird 15 inches longer to accommodate a baffle. And I added 1.7 grams of 4F black powder to insure nose cone separation and parachute...

I am building my AIM-9 short kit from KN. But I have - posers.... I installed a 29 mm motor tube in the fin unit. Glued fin unit to body tube using Bob Smith epoxy. Now I need to find the center of gravity. Instructions say it should be the midpoint of the 22 inch body tube. So I loaded a...

Does anyone out there have a Hangar 11 X-15 with 4 inch diameter? How long is it? How much weight did you add to the nose to insure stability? When did you acquire it? And how much did it cost? Thanks to all. Bob in Phoenix

What is the best adhesive for attaching a Boyce Aerospace fin set (ABS) onto the plastic (styrene) tail of an Estes Maxi Honest John? I suspect there may be several adhesives which will produce good results. Is there a best one? Thanks to all. Bob in Phoenix

I am finally building my old Estes Maxi Honest John kit. I am organizing my parts for upgrades. But one question remains - what is the correct color? The instructions call for flat artillery green. What the heck is that? I've been looking at Rusto 2X 279176. And those little cans of Testors...

Now I've done it. While trying to repair a loose fin, I've managed to break it off completely. Sadness... And no, it's not surface mounted. The rocket is an old THOY Falcon. Four inch diameter, 54 mm motor mount. The fin root is 9.375 inches, and the fin tab WAS 4.125 inches. So I removed...

I have tried several times to install Open Rocket onto my computer. No joy. Message says something about 32/64 bit incompatibility. Oh yeah - I'm running Windows 7 SP1 32 bit. Don't tell me - OP 15.03 is 64 bit? Thanks to all. Bob in Phoenix

On Saturday 20 Nov 21 I took the THOY Falcon to the G. Harry Stine Memorial Launch held by the Superstition Spacemodeling Society (SSS), NAR Section 506. I flew the Falcon on a Cesaroni H163. Great flight, separation just after apogee, and a gentle return on a 60-inch military surplus...

Does anyone know the (1) maximum no-fire current and the (2) minimum sure-fire current for Aerotech First Fire, First Fire Jr, and First Fire Mini igniters? Thanks to all. Bob in Phoenix

Is there a list of F impulse engines which require Level 1 certification? Same thing for G engines. I shall guess (oh no) that any engine with an averge thrust ovet 80 Newtons requires Level 1. Thank you. Bob in Phoenix

I am currently building a THOY Falcon. A real blast from the past. 67 inches long, 4 inch diameter, 30 ounces - mine will probably be heavier. 54 mm engine mount, with adapters for 38 mm and 29 mm engines. Now the bad news. I am not certified for High Power - not even Level 1. So I plan on...

I have several unbuilt old Estes Eliminator kits. They have purple BT-56 tubes, yellow nose cones, and yellow plastic fin cans. Except one. One of them has a BLACK plastic fin can. Is this unusual? Thank you. Bob in Phoenix

Forum: Can Aerotech Economax and/or Econojet single use engines (F and G) have their delays adjusted by drilling the delay charge? Thanks to all. Bob
