Estes Interceptor E converted to RC Rocket glider 3 different ways


I was on the way home yesterday and was thinking about changing my IntR/Ceptor profile model into an elevon only model, instead of one with full flying tail surfaces. This would require moving the wing back and making it larger. I remembered that the hobby shop had an Interceptor E kit that had been sitting on the shelf for a long time. I did some quick checking and thought I could do a modification of this to keep the tube and nose cone and see if I could get it to fly ok. I did some quick wing planform checks and came out with something I thought would work.

I dumped the wingtip pods since they are heavy and will re-make those from foam. I enlarged the existing wing/tail slots to fit my depron surfaces and installed the wing. I made the forward tube section removable along with the strakes so that I can access the mid mounted rail button. It turned out for CG I did need to use the plastic tail piece. 7-8 ounces/sq foot, slightly more than my full profile version. The need for the tail cone for CG means the motor is inset about 3/4"

First flight was really good, slightly nose heavy, and a bit touchy on roll. I adjusted the cg rearward by adding 1/4 ounce to the tail and toning down the aileron. I later replaced the 1/4 ounce of tail weight with the plastic vertical stab antennae which weighed the same overall. I added some panel lines, accented the nose cone panels with a sharpie pen and added some trim vinyl. All up 12.5 ounces rtf now.

Here are videos of all three versions plus my kit profile version.

I decided to get two of the Cosmic Interceptor kits from estes which use the same cone, since they were on closeout for $17 and do two other versions, one with a cranked delta wing and t tail and one with a full flying tail and see how they compared in looks and flight....all three fly quite well...

Loved watching the videos. Appeared that the V-tail seemed to fly better? Is that what you found? Were you using R/C or was that free glide?

They all flew about the same, all were rc, first two gave a longer glide due to slightly lighter weight.
