7-3/4". That's a shade more than 50% of the length!

The JetJoint
Here are the photos. I replaced the setscrews with stainless steel ones I have on hand. I'm almost out, so I'll have to order more.A nation of sheep breeds a government of wolvesComment

looks nice. I might be interested in a few when I get there.
I thought the hydro didn't need a u-joint coupler? At least the original images you posted way back when didn't have them.Comment

No, the hydro doesn't need a U-joint because everything lines up. I may use it in my next SSSH project, a 1:24 SCALE wood boat. A flexible joint will allow me to get the shaft a bit flatter, as I can angle the motor down just a wee bit. And, if I use the "Double-JetJoint", I could get the driveshaft even flatter.Originally posted by Sneasle View PostA nation of sheep breeds a government of wolvesComment

Ah, I see. Good to know.
have you measured any king of optimum angle for the shaft on the hydro?Comment
-
No, but using Garry Finlay's 1:16 scale plans as reference, somewhere around 4º is in the ballpark.Originally posted by Sneasle View PostA nation of sheep breeds a government of wolvesComment

kk, thanks.
I'm going to look into buying up the rest of the FG/CF I need for these guys. Gotta find a radio too.
Anyone know what radio has the cheapest receivers right now?Comment
-
Wow.. over a month with no activity..
I decided to go with the MX-3 for my radio.. I bought an s and a standard in 75mhz, should be plenty of radio for me for the foreseeable future.Comment

I always wanted to be "double "Jet"
Jointed" LOL
And speaking of radios Futaba 2.4 Ghz works real well I do not think they are the cheepest, but you know no one else will bleed into your signal and there are some very compact receivers for them so you guys building minis they are worth the extra price, I had to brave an arguement with my wife after I bought mine!!(
oh mighty controller of the check book!!) LOL again
have fun guysPeter Eells; Fun, and Helping others To Have Fun!!!

ya, i agree 2.4 is nice.. but when I can buy an MX-3 for $30 shipped off of ebay and 2 receivers for $30-$40, I'll stick with the old tech for now :)
I make a conscious effort to enjoy this hobby of ours, in all it's aspects, on the cheap. Now, some of my planes are built with very nice 'name brand' equipment, but they rest fly just as well on the cheap stuff.
Granted, I do fly with a JR 9303 and almost exclusively JR receivers, but JR receivers are nice and cheap on the used market now because of 2.4. Heck, you can even buy a new JR 7ch Synth PCM receiver for $28.Comment

Well, I thought I would spend a few moments updating this old thread.
I've kinda burned-out on boat building and have re-focused my energy into building a pond/waterfeature in my yard, adding a bunch of brick flatwork, and working on widening the fenders on my glider trailer.
I put a new, wider axle under the trailer last October, and the fiberglass fenders have been languishing in my shop for quite a while. I cut the outer lip off with a Dremel tool, then moved it about 2" further out; then using some CF tubes on the outer surfaces, epoxied it in place. Then I layed-on a strip of 1.5 oz. cloth, covering the resulting gap. After that went off, I started adding shredded fiberglass/epoxy mix to fill in the gap. When the gap was filled. I sanded it smooth on the inside, and layed in some heavy FG mat.
When that cooked off, I ground off the CF tubes, filled in the remaining low spots on the outside with shredded FG and epoxy. After that went off, I sanded it smooth, and layed on more FG mat.
The fenders are now structurally sound and just need a bit of Bondo here and there to fill in any low spots. Then a LOT MORE sanding, priming and painting.
It's a long process because there is a minimum of 24 hours between each step, and often it's more like a week between steps.
I'll get back to the MTH after I burn-out on, or finish my other projects.
Stay tuned.

I want to share with you mu just finished project, this is my first built other than fast monos and I am amazed on how fine the shovelnose looks, haven't had the chance to try it yet. After a series of setups I concluded to this:
MHZ Micro Classic Shovelnose, got it bare hull with hardware and scale-looking details, from a friend.
Added a scorpion 2221-8 3600KV that I had lying around (tried inrunners but the hatch could not close properly)
Scorpion 35A WaterCooled ESC
2 X 1450 7.4 20C Lipos in parallel
ETTI Collet
Hitec HS-82MG metal gear for high speed turning, as servos take quite a beating in these hulls
Futaba 3PM FM Synthesised, if I like it a lot will swap it for a 2.4 one...
Now I need to find a way to watercool the motor, although since the ESC is watercooled and the weight it has to push is little could not be needed, I will know on the first run.
Here is a photo of the setup, any comments/advice are mostly welcome...
PS. The ESC is in the right sponsoon and added flotation to the left and the bow...Comment

Decided to take it a step forward and try to run it with 11.1 1500mAh 20C which gives me nearly 40000rpm...Comment
-
Final setup.
11.1V 1500mAh 20C, 2.4GHz, 43000rpm, bring it on... The ESC is in the right sponson and the battery on the left to have proper balance and reduce torque roll...
