CARF Bolt! Build thread
#152
thanks Dave, that’s a good reference and gives me an idea what to expect…
I ended up making longer linkages and changing my arm geometry a bit, and I get the full 35m+ and 30mm- on the elevator now. Using a 20mm hole on the arm, this just about maximizes the travel range on the JR 5955 I’m using ..

Can someone tell me, are the Bolt's struts just off the shelf electron struts (S, M, or L etc) or are they custom? I have a set of er-50 from my rebel pro Id like to use. I cant see to get a clear answer from CARF and electron is on vacation.
Also, if anyone can, if you have seen the Picaro and can compare Id be interested. Im real close to one of the two and was settled on the bolt but cant figure out this strut issue.
Thanks!!!

I'm supposed to be getting my Bolt early next week and if I remember correctly I was told the the Bolt's nose strut is a different length than standard length than come from Electron. I could be wrong but that's what I remember being told.

Hi all
I've flown The Bolt this season and about 8 engine hours now. At first I wasn't that impressed about the plane mostly because of sensitive controls. I moved CG more aft and elevator went even more sensitive... just not my liking maybe perfect for others. Now with reduced control throws it is MUCH better for me. My elevator arm is about 12mm and aileron 13mm. Just need to readjust gyro and such... Rudder servo was also too slow for gyro at first better now. Knife edge is not perfect yet opposite aileron is needed. There are notable trim changes between flight modes so I advice to use delay between modes. In principle it's slippery and really want's to go fast. I noticed slight tip stall effect on full flaps but I believe my lateral CG was to blame.
I do like CARF build quality. Specially landing gear mounts are very strong and build from real carbon and plywood unlike most of the bunch. Wing seems to be full carbon and head mounted flash light is needed when doing any work inside it. Fuselage is also black hole to work with even there is more glass in it. Construction is well thought and manufactured. Fuselage is full sandwitch and handles miss-use well. Only canopy and tailcone are single laminate. Maybe the biggest issue on the plane is hard main landing gear... still to be reworked someday. But try to use as much angle on knee if you are building one now
My smoke nozzle quick connect blew during the flight and whole fuse was flooded with oil. Thanks to sandwitch there is not much wood to soak it in so I think I avoided huge rework there... anyway it's very promising at the moment and going to be really good when tuned right!

I just put in a order for the victory scheme. I like it as it will be simple to fix.
Was really on the fence between this and the picaro but decided to stick with CARF.
I got an email from electron the struts are off the shelf you can order from the website, no custom machining.
I wont be flying this for awhile though.

Just a couple notes, I asked on the EA FB group about the Picaro Vs Bolt. There were three things that swayed me to the bolt:
EA people were willing to say negative things about the bolt, but CARF spoke with respect about picaro.
Sounds like there are alot more Picaros out there than bolts, so that right there is a good reason to get a bolt for sure. im not a crowd follower.
EA is not accurate on timelines,they throw around a 6 weeks number. But they neglect to mention shipping times and CARF says 16 weeks. Both CARF and EA are about the same timeline which is around 4 months to my door.
One other thing, the struts being off the shelf is something I like, If I need another one or parts very easy to get!

He said the bolt "does funny things" lol
They deleted my post so I cant prove it now, but it was the EA people. Im sure they make a great jet. Its not big deal.
The Picaro is a blatant copy of the Ultra bandit and the bolt is its own thing.

Thank you Dave, hoping to have mine done in a less than two weeks. I run several small businesses and it's hard to find time to build anymore. Do you remember what amount of elevator you add on takeoff flaps and landing flaps?

I have the OMG servos on my EA BDX that came PnP . I am very pleased with them. Super smooth, pretty quick and strong. They also have soft start which is a nice feature to have. .
also for consideration …..
I have been liking the McGregors CARF supplies and uses on their planes . Those also are excellent servos. I have been flying these on a Rebel and now recently on an ultra flash too… super responsive and precise feel ..
ironically , JR 89xx 2k servos are what I am having the most issues of all right now. All the new servos run rough and “notchy” … they lose steps and don’t always center . I’m trying to work with JR and reps to see if there is a fix. these are what I have throughout my Bolt and I’m considering just going MKS or McGregor for this plane on primary controls

I don't think I have found a solid CG point on the manual or on this build. Does anyone have a actual measurement from a point to a point where that is? I've been told to make the weight on the nose gear from 1300-1500grams.

I don’t remember my number, but what scheme are you again? There is a picture of mine hanging on wires at the balance point on the Victory scheme.
#171
you cant really go by weighing the weight in the nose as this will be relative to the percentage weight of the whole plane where your specific one ends up ... I know they wont come in far off from each other , but turbine choice, battery count and spec, smoke, etc will add up ..
#173
The bolt is like a freight train locked in on rails. It will do every bit and more of what it’s advertised to do.. The most incredibly solid, precise, flying jet I have ever had my hands on. It will pull ridiculous Gs at super high speeds also. And then it slows down and still maintains its stability. Landings are super solid and predictable. The way the bolt is engineered is also ahead of anything else in the hobby. The most solid built and well engineered RC jet ever.. A lot of the plane is laid up in carbon fiber as needed, and there is a good amount of innovation in how it is assembled, including a full bypass system that mounts up in a matter of minutes.
The ultra flash is super quick and agile, and super fun however, it’s a little bit less stable at slow speed. Slow Flight performance is not as good compared to the Bolt. Depending on your CG, you can bounce the UltraFlash on landing… I really do wish there was an option for full ducting and bypass on this jet still, but the Evo does away with all that for the sake of simplicity. It really shows, even on the larger engine the plane hits an aerodynamic wall.
I love both Jets in different ways but so much that I got two of each. Either jet is virtually unbreakable. You will destroy the bearings on your turbine before either lets go structually. if I had to pick one, Bolt by far though!

Thank you for your quick reply. I am more assured now to make the investments on the Bolt now as it is not cheap. Just curious what is max speed for bolt, what turbine size would you recommend to get the most of it, is the Bolt flying the same or faster than Flash? I am also debating if I should get a bolt or Mephisto V2 as I also like 3d flying. Your thoughts and view?
#175
Kingtech K260 or jetcat P250. These are the largest engines that will fit, and the jet is pretty much designed around this size engine with the bypass. It will go very fast. I have many flights now on the k260. I have not flown the pink one with the P250 yet ..
