Sorry this post is so late! Been having awful problems with my internet provider for more then a month. Last 5 weeks I haven't been able to do anything other then read.
Anyway at Narhams annual Christmas Party our members had a great time and were rewarded with some outstanding food, Rafffle and best of all some Give-Aways from our favorite vendors.
One of these Great Little Freebee's was an Metallic Purple Rocket Ornament made by Estes. This rocket ornament came with a Not Intended for flying lable. Well; now that sounds like a challange. The Ornament dimensions are OD of .725", OA Length 5.25" and a Fin/Wing Span 2.5". Which seems more then sufficent for a rear ejection Micro Maxx to BT-5 Centering Ring Pod.
After some minor plastic removal of the rear closure plate I noticed one of the internal support pins that would need to be removed before a minium length ejection pod. The internal body tube ended up being BT-5+ 1-3/4" long, into which I white glued a 1-1/4" length of BT-5. As a bulkhead & pod stop a 1/4" balsa disc which it wedged 1/8" into the foreward end of the BT-5+ tube. after dry fitting the forward bulk head the inside face was clad with 2 layers of .020" Stainless Steel Adhesive backed tape then epoxied in place with 36" of 100lb Kevlar shockline.
Fashioning the Rear Ejection Pod started with the motor tube a T-2+ Tube cut 1-3/4" long. Fiber BT-5 to T2+ Centering rings were epoxy located 1/4" from the aft end and at 1" leaving space for a 1/2" x 12" yellow teflon streamer attached to the T2+ motor tube with 1/2" mylar tape.
our Shockline is also tied around the Motor tube under the forward centering ring. A 3/16" piece of T2 body tube is glued into the motor tube allowing 1/4" of motor to extend from the rear of the T2+ motor tube allowing both internal and external tape motor retension. the only other thing needed was to add a single MMX launch lug to the aft end centered between the Fin/wings aligned with the provided Tree hanger lug.
I really expected this model would need some additional nose weight but swing testing proved it is stable without adding anything.
Final EWt; is 14.6g adding a MMX-II motor and tape our LOWt; is 15.7g Should be a fine flying addition to the MMX Fleet.
Our December Sport launch was cancelled due to nasty winter weather so looks like I won't get to fly this new addition until Feburary.
It's great to be back up and running..YEAH!
