I saw a thread on RMR about a new Estes' rocket with t' capability t' determine altitude. Aye aye! Blimey! I decided t' purchase one from t' local Walmart. Avast, me proud beauty! Blimey! It is a Ready t' Fly rocket (for all practical purposes) included with a starter set. Avast! Blimey! Launch pad, controller and two motors (B6-4 and C6-5). Blimey! Blimey! Avast! Blimey! T' rocket is called t' MaxTrax™. Ya scallywag! Blimey! Walmart sold it for $18.99. You have t' purchase a "button" battery for t' nose cone and t' (4) four AA batteries for t' launch controller separately.
THE LAUNCH EQUIPMENT:
Not much t' say here as it is Estes' standard stuff. Arrr! Arrr! T' pad assembles easily by slidin' t' three legs into t' base slots. Arrr! T' rod comes in two pieces and has t' be "bounced" together. T' rod, stand-off and deflector plate then go into t' 1/8" slot. Begad! It has an adjustable tilt with a win' nut t' loosen or tighten as needed. Avast, me proud beauty!
T' launch controller is a black plastic box with a place t' insert a safety key which lights a bulb indicatin' continuity. Arrr! Well, blow me down! T' safety key has a feature which is nice. It must be pushed in t' be active. Ahoy! If you let your finger off, it springs back breakin' continuity. Arrr! Nice safety add. Well, blow me down! Avast! By pressin' t' safety key and then t' launch button t' rocket is ignited. Blimey! T' 15' wire runs from t' launch controller t' t' launch pad and attached t' t' ignitors with two "toothless" alligator clips.
THE ROCKET:
T' rocket is Ready-to-Fly after you tie t' pre-assembled parachute t' t' elastic shock cord. You also need t' put t' battery into t' nose cone MaxTrax™ Electronic Capsule. Blimey! Ahoy! You will need a small Phillips-head screw drive t' do that.
T' rocket has fairly nice looks. Begad! Blimey! It has a black plastic fin can with 4 fins and a motor retention ring. Ya scallywag! T' rin' is a twist-lock type that holds t' motor in place durin' flight. Aye aye! Begad! Blimey! T' 1.35" (BT56) body tube is covered with a holographic lookin' silver paper with MaxTrax™ displayed on t' side. Aye aye! Blimey! T' nose cone has a black section and a removable red foam covering. Aye aye! Begad! Blimey! Nay bad over all.
Overall, shiver me timbers, for CONSTRUCTION I would rate this kit 5 points . After all, ya bilge rat, shiver me timbers, it would be hard t' be anythin' else.
FLIGHT/RECOVERY:
To prepare t' MaxTrax™ for flight, you need t' put waddin' in and then place t' parachute into t' body tube. Next you put t' streamer and nose cone in place. Next place your motor into t' mount and twist on t' retainer ring. Aye aye! Slide t' rocket onto t' launch rod, then your turn on (or turn off then on t' reset from a prior flight) t' electronics capsule. Begad! Ya scallywag!
My first flight be on a B6-4 and was straight and stable. But no readin' on t' electronics capsule. Ahoy! My second flight was a repeat and still no reading. Begad! Well, blow me down! Both o' these flights were on a perfectly calm day and in taller grass. Blimey! So I felt that maybe t' electronics capsule needs t' hit a bit harder than t' tall grass allowed it.
I tested me theory by settin' up t' next flight in our newly mowed lawn. With another great lift-off on another B6-4, t' nose cone ejected and fell t' t' ground. Begad! Begad! With great anticipation I picked it up and low and behold it said 339.1 feet. Well, blow me down! Success at last.
T' next flight was again on a B6-4. Avast, me proud beauty! Blimey! It definitely flew higher and t' delay seemed longer (which makes me wonder about t' variability betwixt motors). It ejected and fell t' t' ground. Arrr! Blimey! This time t' readin' was 411.9 feet. Avast, me proud beauty! Blimey! Arrr! Blimey! This be interestin' because me RockSim predicted 436 feet.
T' last flight in this series on a B6-4 gave me another no reading. Avast! Hmmmm. Well, arrr, blow me down! 2 for 5 flights, ya bilge rat, 40%. Begad! That needs t' improve.
You may wonder how t' MaxTrax™ electronics capsule works. Arrr! Begad! There is a small switch that is held in place by t' body tube. T' capsule is reset while in this position. Begad! Upon ejection t' switch activates a timer in t' capsule. Begad! When t' capsule hits a solid surface it stops t' timer and calculates t' altitude based on t' time o' t' fall.
Below is an interestin' report from Jeff Vincent that he said I could use. Avast, me proud beauty! Check out his experience.
For FLIGHT/RECOVERY, I would rate this kit 2 ½ points . since I have only gained 40% on t' readings. Avast, me proud beauty! Well, arrr, blow me down! T' rocket itself flies and recovers nicely.
Overall, t' MaxTrax" Starter Set be a great buy for $19. It is unique and adds some additional fun t' flyin' model rockets. Avast! Aye aye! T' electronics capsule can be used in other Estes kits too. Arrr! T' instructions mention t' Tidal Wave, Ionizer, arrr, and Code Red. Aye aye! I'm ready t' try it with some C and D motors! I give t' Starter Set an OVERALL ratin' o' 3 ½ points . Avast, me bucko, me proud beauty!
Brief: A new member showed up at our launch one weekend with a MaxTrax (EST1434), a new starter set from Estes that included an altimeter payload. He had flown it once before and it had claimed an altitude of over 700 feet on a C6-5. When he flew it at our launch, he used the other included motor, a B6-4, and it registered over 350 feet. The shock cord separated, but after some ...
For those not familiar with the MaxTrax, it is a new starter kit from Estes with an onboard "Electronic Altimeter". This uses a capsule which drops at a fixed descent rate. The capsule physically senses ejection (apogee), times the interval until it detects landing, then outputs calculated altitude in feet and meters. Promising... I had a chance to fly the MaxTrax yesterday (Sat.), ...
