I saw a thread on RMR about a new Estes' rocket with t' capability t' determine altitude. I decided t' purchase one from t' local Walmart. Blimey! It is a Ready t' Fly rocket (for all practical purposes) included with a starter set. Ahoy! Launch pad, ya bilge rat, controller and two motors (B6-4 and C6-5). Arrr! T' rocket is called t' MaxTrax™. Avast, me proud beauty! Walmart sold it for $18.99. Begad! Avast, me proud beauty! 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. Ya scallywag! T' pad assembles easily by slidin' t' three legs into t' base slots. Avast, me proud beauty! T' rod comes in two pieces and has t' be "bounced" together. Begad! T' rod, shiver me timbers, stand-off and deflector plate then go into t' 1/8" slot. Blimey! It has an adjustable tilt with a win' nut t' loosen or tighten as needed. Well, ya bilge rat, blow me down!
T' launch controller is a black plastic box with a place t' insert a safety key which lights a bulb indicatin' continuity. T' safety key has a feature which is nice. Blimey! It must be pushed in t' be active. Well, blow me down! If you let your finger off, arrr, me hearties, it springs back breakin' continuity. Well, blow me down! Begad! Nice safety add. Blimey! By pressin' t' safety key and then t' launch button t' rocket is ignited. 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. You will need a small Phillips-head screw drive t' do that.
T' rocket has fairly nice looks. Blimey! It has a black plastic fin can with 4 fins and a motor retention ring. T' rin' is a twist-lock type that holds t' motor in place durin' flight. Well, arrr, blow me down! T' 1.35" (BT56) body tube is covered with a holographic lookin' silver paper with MaxTrax™ displayed on t' side. Well, blow me down! Avast, shiver me timbers, me proud beauty! T' nose cone has a black section and a removable red foam covering. Nay bad over all.
Overall, me hearties, for CONSTRUCTION I would rate this kit 5 points . Begad! Arrr! After all, 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. Ahoy! Next place your motor into t' mount and twist on t' retainer ring. Slide t' rocket onto t' launch rod, shiver me timbers, me hearties, ya bilge rat, then your turn on (or turn off then on t' reset from a prior flight) t' electronics capsule. Begad! Blimey!
My first flight be on a B6-4 and was straight and stable. But no readin' on t' electronics capsule. Ya scallywag! Blimey! My second flight was a repeat and still no reading. Well, blow me down! Both o' these flights were on a perfectly calm day and in taller grass. 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. Ahoy! With another great lift-off on another B6-4, t' nose cone ejected and fell t' t' ground. Avast! Avast, matey, me proud beauty! With great anticipation I picked it up and low and behold it said 339.1 feet. Aye aye! Success at last.
T' next flight was again on a B6-4. 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. Well, blow me down! This time t' readin' was 411.9 feet. Arrr! This was interestin' because me RockSim predicted 436 feet.
T' last flight in this series on a B6-4 gave me another no reading. Ya scallywag! Begad! Hmmmm. 2 for 5 flights, me bucko, 40%. Aye aye! That needs t' improve.
You may wonder how t' MaxTrax™ electronics capsule works. Avast, me proud beauty! Blimey! Avast! Blimey! There is a small switch that is held in place by t' body tube. Blimey! Blimey! T' capsule is reset while in this position. Ya scallywag! Blimey! Upon ejection t' switch activates a timer in t' capsule. Avast, me proud beauty! Blimey! 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. Ahoy! Blimey! Blimey! 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! T' rocket itself flies and recovers nicely.
Overall, matey, me bucko, t' MaxTrax" Starter Set was a great buy for $19. Ya scallywag! It is unique and adds some additional fun t' flyin' model rockets. Blimey! T' electronics capsule can be used in other Estes kits too. Arrr! T' instructions mention t' Tidal Wave, Ionizer, and Code Red. I'm ready t' try it with some C and D motors! I give t' Starter Set an OVERALL ratin' o' 3 ½ points . Well, blow me down! Begad!
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.), ...
