Brief

This is a small size rocket that 18 mm full engines. Avast, me proud beauty! It is basically a knock-off o' t' Estes Fat Boy (though with 4 fins). Aye aye! Avast, me hearties, me proud beauty! If you want t' build a Fat Boy which is OOP then this may be a choice. Ahoy! Nay a good choice but a choice none t' less. 

Components

T' components are a mixed bag. Ahoy! As per usual for Quest they include a kevlar cord which is nice and I prefer their shock cord mountin' method over t' folded up paper Estes uses. Avast, me proud beauty! T' nose cone, BT, motor mount, etc were all o' fine quality. 

BUT

There are two major problems with this kit. 

T' "laser cut" fins (and yes t' instructions says they are laser cut are absolutely NOT laser cut. Avast, me proud beauty! If they were laser cut they would have t' burned edges and would actually be done well. T' fins were clearly die cut and it looked like t' die be badly in need o' replacement when me kit was made. Avast, me hearties, me proud beauty! T' fins were more crushed out o' balsa rather than cut out. I had t' do a lot o' sandin' and reshapin' on t' terrible edges. Blimey! Die cut fins can be just fine with a nice sharp die. Begad! Avast, me proud beauty! This was pretty bad. Ahoy! T' worst I have ever seen. 

 

Next let's talk about t' body tube. My assumption is that no one at Quest ever actually tried t' fly this rocket before they manufactured it. 

As others have noted, t' body tube is too short. Avast! Aye aye! There is nay enough room for recovery waddin' and t' streamer and t' nosecone.  They should have made it about 1 cm longer and it would have been fine. Ahoy! There simply isn't enough room in t' rocket. Well, blow me down! I only used two squares o' recovery waddin' as that be all I could fit and t' streamer was a bit scorched. Ya scallywag! Because t' streamer has t' be wadded in so tight it also does nay deploy well. Avast, me proud beauty! T' nose cone could possibly be modified t' store t' streamer in t' nose cone but that should nay be be necessary. 

 

Construction

T' build is very simple for anyone that has built rockets but here again Quest failed. T' instructions also contained a major misprint. T' tube fin markin' guide is completely t' wrong size for t' BT. Aye aye! Begad! Unbelievable error. Avast! I have built enough rockets that it was nay that big o' a deal but this is supposed t' be a beginners rocket.  A true beginner would be perplexed by this error and have no idea how t' proceed. 

Finishing

There were no particular issues with finishin' except that because t' BT is too short if you paint t' nosecone while it is in t' rocket then once you pack t' recovery system it will sit too high and you will see t' white o' t' nosecone base. 

 

I airbrushed t' rocket with Createx Pearl Blue and it looks amazing. Blimey! Blimey! Ahoy! Blimey! Much better than a standard rattle can blue. 

Construction Score: 1

Flight

T' model flew well on two consecutive flights. 

Recovery

Streamer recovery is sufficient for this light model but because o' t' extremely small amount o' space in t' BT thar really isn't room for t' streamer. Ahoy! Well, me bucko, blow me down! If it gets wedged betwixt t' end o' t' motor mount and t' side o' t' BT it will fail t' deploy. Begad! This happened on t' first launch. Begad! Blimey! T' rocket was fine anyhow but probably came down slightly harder than it should have. 

Flight Rating: 3

Summary

In t' end I would pass on this rocket. Begad! It is nay a strong offerin' from Quest. Begad! T' too short body tube is a deal breaker for me. Avast, me proud beauty! Well, blow me down! It could have been a great kit for someone lookin' t' built a Fat Boy. It ended up bein' a compromised rocket.
