The distance a rocket drifts is determined by the wind speed and time it takes to descend, not by the type or number of parachutes used. So, if you have one, a single larger parachute would be better than three smaller ones. There would be less tangling of the shroud lines and one 'chute would be easier to pack into less space. -- Roger |

I'm still waiting to receive the Maxi Alpha III I ordered from Hobbylink.
I flew my original 1983 vintage MAIII so often I wore it out. The motor mount tube had a burnthrough from all those AeroTech 24mm 'E' motors. I used quite a few D12s, also.

The REGULAR Maxi-Alpha was much better than the Maxi Alpha 3 as it had WOOD fins instead of those DUMB easily breakable ring-lok plastic jokes.
The best would be to offer the ORIGINAL Maxi-Alpha (not 3) with either basswood or ply TTW fins that can take some REAL power. Shredded the fins off my buddy's Maxi Alpha 3 on its 2nd flight with a Compsite Dynamics 24mm Pro-Jet F something in 1988. He was displeased with the 125' on a D12-3 and I handed him the Composite Dynamics 80 n-sec F that stuck out of the mount bottom by like 4". Fins shredded off at about 250' but kept going up fairly straight. His response was "Geez, thanx !". I told him to GLUE some REAL fins on with epoxy and quit whining.

I have never seen Balsa ply before, just regular Spruce Aircraft Ply and Poplar Lite(useless) Ply.
Is that something one can order or is it some sort of home-brew balsa ply ? I think I may turn my MA3 I ordered into a Colossus instead with an additional tube and wood fins for strength.

It's long OOP, but I still have a some left from a purchase I made years ago. I also roll my own. I use two outer layers of 1/32" balsa over an inner layer of 1/16". I glue it with yellow glue, then clamp it for a couple days between two very carefully eyeballed (for planarity) pieces of birch. Some aluminum foil makes a good release layer to keep from glueing your balsa to your birch (which is not quite as bad as glueing your hand to your special purpose ) Doug .

Well that's what I did, and I also ended up changing the paint scheme as well. Flies great on an E15-4.

The picture was taken at Mile Square Park. I still miss that flying site. I'm not sure that is you sitting at the table, Fred. I'm pretty sure that is Martin standing behind whoever is sitting at the table.
