RG65 Cobra5 Patterns

pics as promised. only late…:slight_smile:

used cotter pins for deck attachment points for shrouds and back stay pics of the reinforced spots on the deck rudder tube, rudder, keel…which one??? and made a small rack for the jib attachment…

rig is finished…

860 grams

with hatch cover, 910mah 2 cell lipo, and spektrum reciever

keel with bulb weighs 480g

keel fin is a carbon/basla heli rotor

all I have left to do is trim the rudder tube flush and seal around the hole. and seal up around the keel/hull joint with some silicone caulk…which knowing me will take 2 weeks…

I hope you have some soft water down there, Marc…I’m sure many of us are anxious to hear how that rig works out.

Keep us posted…soon!!

Craig and I are going to try to get our boats wet on friday…at the pond in front of the capital…it was 65 yesterday, only to get up to 45 today but 60 on wed, thurs and friday
our biggest concern is depth at the fountain…the ranger I buildhas a 15" draft…so it may not work if the fountain is not full. and I’m not ready to start shortening the keel without some testing

Claudio
has proven the concept works on one of his RG’s but it will be neat to see how it does on the skinny boat. I will probably float test mine tonight in a small creek behind my house… Keel and rudder and setting up right now at home…

picture is worth 1000 words…

well it sails…

it took on a small amount of water maybe a thimble full…so it could have been deck joint, rudder tube or keel area. so now I need to take the rig apart , label the sailand figure out were the water is coming in. I was on the water fro about 20 minutes

the deck was not ever under water but it did heel over a few times to get the deck hill joint wet.

shes riding a bit low in the stern which means I can move the electronics forward of the keel…to get her on the water line

a bit of weather helm… so I’ll try moving the sail forward first and then go from there…

That’s the best part; seeing the results of the work.

well I made a new jib, and repositioned it further froward and sailing in light air against some Gifs that Craig built it was a very strong boat.

I think I need to to make a slightly larger rudder. in light air no way to “scull” to change tack…

Marc,

Sculling is illegal in sailboat racing! Don’t try it at a regatta, if you get caught you could be disqualified.

And congratulations on the launching!

actually neil you CAN scull a boat for the purposes of tacking…

42.3 exceptions
(d) When a boat is above a close-hauled course and either stationary
or moving slowly, she may scull to turn to a close-hauled
course.
(e) A boat may reduce speed by repeatedly moving her helm.

well a larger rudder and reposition sail pulled in a 3rd place at the richmond regatta this weekend…andonly 4 points out of 2rd and 17 points out of first…

now I need ot make my sail the max size allowed and work on the thumbs and tuning…

Close is in horseshoes !
3rd is 3rd buddy.
I could say I’m tied for 5th we each beat the other 7 times…

close only counts in throwing horseshoes, handgrenades and spreading fertilizer… Iknow.

I was just bragging about how well the round ranger with the huzway vacuform technique did.

and you placed 6th with 63 points, and scott placed 5th with 60 points. No ties for you buddy…

ina ll honesty if you aint in first place, you lose…:slight_smile:

and I beat you 11 times…:slight_smile:

I think the RR is a good hull and will proper tuning and sailing will do well. Walter is tough to beat.

Hi Marc -

I gotta ask … regarding the JIF design. Were they that “slow” or skippered by a new owner? Having trouble seeing all of them clustered at the bottom of the pack, when South American results have them “sprinkled” throughout.

Thanks, Dick

I won’t stomp on Craigs parade, but they are his jifs… and they were sailed by some newer skippers (craig has a traveling armada). they are also, IMO a bit on the heavy side,… and with the light winds we had, not the in their prime.

craig and I have sailed my ranger against in jifs in heavy air and seas and they were quite capable boats. but I think the combination of the newer skippers and light air made for the less than stellar performance.

between the 4 boats they had 8 top 6 finishes… which isn’t stellar, but it shows the boats and the skippers have potential. I believe 3 of those 4, this was their first R/c regatta as well. Making the tranision from “big” boats is harder than most people think…

Marc is being kind. yes they weigh a ton. about 1400g. 3 were mine and in a blow do just fine.
The other gentleman with one was having mechanical problems. you can see all the DNF’s
not good for your score as I found out with 2 myself.
I could have been 5th :frowning:

Guys -

thanks for the details and response. I have continued to recommend the JIF to those interested in building an “easy” r/c sailboat. My recommendations based on materials, time for glue-up of 4 panels and a deck, and because of it’s size. Locally there are no other designs at this time, so sailing and tuning becomes rather limited. I will continue to provide recommendation of the design, but will also stress the need to build reasonably light weight in order to be somewhat competitive in light to medium air.

Also want to add I certainly appreciate all of the past and current interest/efforts in this class. It seems as it is starting to mature, and probably the next effort is to get some class racing scheduled closer to home for many in a variety of states. The cost and ability to travel will continue to impact these efforts, but would be nice to see the US having areas of about 6 hour driving time maximum for some planned regattas. Obviously less is better, but extended travel is the key to help promote the class and continue to raise local interest. It always “pains me” to read comments about the regatta site being so far across town - which seems rather a hinderance to efforts to continue class growth.

Just some thoughts

Dick

Hi Dick
you say “Locally there are no other designs at this time”
Another boat I recommend for an easy build is Round Ranger Hull and deck.( Yes I’m biased as i make them)

They not on the first page anymore hit next.
So far they are in 16 states.
First RG Regatta I have seen was in Richmond and rangers were 2 and 3 and 6 out of 11
