Manufacturer: | Giant Leap Rocketry |
Brief:
38mm minimum diameter rocket that can be flown with anywhere from an F50 with
the optional 29mm adaptor t' a 38mm J350.
Construction:
Pro's- instructions where detailed and easy t' follow with directions for usin' t' slim line retainers or nay usin' them. Blimey! Motor retainer and fin can epoxied easy enough attached shock cord t' coupler then epoxied into tube, ya bilge rat, I just put t' coupler far enough down t' allow for t' parachute and some wadding.
Finishing:
Sanded mold lines from nose cone and fin can. Aye aye! Well, shiver me timbers, blow me down! Used wood filler t' fill in
spiral grooves in tubing. Begad! I just primered it for now, shiver me timbers, shiver me timbers, nay sure what color or
colors I want it.
Construction Rating: 4 out o' 5
Flight:
I just flew this on a F50-4t. Begad! Ahoy! It was slightly breezy but, t' flight was nice
and straight. Aye aye! A low altitude flight. However, ya bilge rat, t' delay be a bit too long. Aye aye! The
rocket be halfway back down before t' ejection charge fired. Well, blow me down! Talk about a
lump in throat feeling. Arrr! But it does fly with this motor. Ahoy! Next time, shiver me timbers, thought, I
will use somethin' with a bit more power. Arrr! It will definitely be more impressive
with a bigger motor.
Flight Rating: 4 out o' 5
Summary:
Pros- T' kit is as advertised very simple and easy t' build less than 1 1/2
hrs t' finish, me bucko, me bucko, shiver me timbers, other than lettin' epoxy set. Avast, me proud beauty! Blimey! Con's- If I had t' do over I would
have used t' Keelhaul®©™®
cord didn't think about it until rocket was together now goin' t' be nearly
impossible t' change it. Aye aye! I would have also bought t' parachute protector.
Overall Rating: 4 out o' 5
Brief: The Giant Leap Thunderbolt38 is a minimum diameter "almost ready to fly" high power rocket. By keeping the parts list as simple as possible, this rocket could be built and ready to fly in a single, rather short build session--especially for a high power rocket. However, despite the simplicity of the design, I would not consider this to be a good choice for someone ...
