Perhaps BVM just upped their game in the last few years but I'm not seeing any issue with glue sticking to the glasss as long as you use the right glue.

Something like CA needs surface preperation for sure. Also, remember BVM has been bulding for a long time, maybe residue was an issue before, maybe it's just an issue that pops up from time-to-time, them saying it is to cover themselves in case. I think as a builder you need to learn what works and what doesn't, everyone has their own peeves and things they think are necessary as well as things they think are not necessary...

Hey Jack

Cheers for your input !
You know I would call myself not a perfect builder, especially not for Composite as this is my very first Composite Jet. But I do have therefor some extensive experience when building and modifying foam jets.

2 of my mates from the field put me in a very anxious stress situation when they told me that I made a grave mistake by NOT cleaning the surface after sanding with acetone or anything similar.
This would cost me not only a 4000dollar plane but also probably be a reason to quit this Hobby.
I was very afraid afterwards and therefor launched a thread here on rcgroups.

All the Rest now of my Spark is being sanded and cleaned..but these are not such vital points like the control surfaces.

You know..I know how to handle Computers,Servers ,etc...as being a Microsoft System Engineer and Project Leader and I know what to do if something brakes down..but this ...this Spark means the whole world to me and I would shoot myself in the foot if it will happen, as my maiden flight is approaching at vast speeds.

I gotta take some pills maybe to actually cool me down when doing the maiden and just to chill.

This Jet is a preparation of going for my Electra in the Future(2012), so I need to get it done right.

Actually cleaning before sanding keeps from grinding the contamination into the glass surface.

NS,

I'm a computer geek too, 20 years in IT, almost exclusively Microsoft technologies. You do what you feel comfortable with, in the end that's all that matters. Just don't put too much stock in what ANYONE (including me) says, you still have guys that insist RX's need to be wrapped in foam to prevent vibration, despite the fact that vibration shouldn't affect a solid state component. Anyway, I have to be careful what I say before someone jumps on me for that comment, heheh...

Cheers and good luck, post video!

Yes I know Jack, but you see I think I made a possible mistake, costing me probably if it turns out bad a crazy amount of money to rebuild this Spark in case of a contact surface loosing it's bond.

However I just finish the Jet and go fly it...I will see then what will happen..if it happens to be a crash or not..I hope truly not.

Besides..we use and me of course as well mainly Microsoft Technologies and I am quite happy with the latest offerings from Microsoft on the Server side,etc.

I am sure if we both would meet 1 day, we could share some information between each other
I may not as long as you be in IT since I am only 28, but I am working now for more then 12 years with Computer Technology, Security, Cisco, Citrix, VMWare just to name a few.

Love this Job

Hey guys. Well UPS just dropped off my brand new Electra. Woohooo. Waiting on some additional parts before I start building.

I have been saving forever and so excited so actually see one up close.

Congrats my friend! You now own the best flying jet on the planet (yes I said jet, not EDF). Even Pablo misses his Electra at times when he flies his eBandit, the performance of the Electra is simply amazing in the right hands yet smooth and predictable in less capable ones. Feel free to ask about anything you need help with, there are quite a few guys here that would be happy to help...

Thanks guys. I was really amazed at the quality as I was pulling it out of the box. It was flawless.

They were backordered on the struts and the EVF2, so hopefully not too long on those. But what was really neat is they shipped a full EVF2 shroud (no rotor, stators...etc) so I can get building. How cool is that?

Any tips I should keep in mind that are not in the manual? Someone said that you should apply a coat of wax to the exterior before you start building so if you get glue smudges or other stuff on it, they will come off easier.

I picked up the aeropoxy with some self-mixing nozzles. Any advice on using? Are the nozzles only single use or do they need to be capped / cleaned?

Let's see...what else. Oh...main gear doors. Is it worth making doors for the bottom half of the wheels or just keep it simple? I'm not going for speed (10s) and really value reliable over anything else.

Off topic a bit, but do you all know if Tam's TJ120 PNP is a simple drop-in for my ELectra ARF? I miss that sound of the 127mm Dynamax/Scorpion in the Cermark Viper I had, but sold. Thanks for any words of wisdom!

Go with the stock door setup for sure. Its simple and very effective.

For the nozzles I just one use them and toss them in the trash. I get all my hysol jobs lined up and do as much as I can at one time. For smal parts you can just mix it with no nozzle. But man thier is nothing better for building jets then the hysol with the nozzels.

BTW you can clean them but what a pain. For a few bucks for 3 of them I would just buy extras. Reliablity on this plane is the best part. I go to the feild fly then hang it up when I get home with nothing to do .
Did you get the kit or ARF?

Absolutely, until you get one in your hands you just can't imagine the quality. BVM glass work is absolute art.

I don't use the wax trick but Rob Lynch swears by it. I find myself washing my hands quite frequently, which helps. If you do try the wax, just rub it on and let the haze dry, nothing will stick to that.

Chuck them after use, you can try and save all your epoxy work 'till the end of the day to maximize value but I just treat mysef to a new bag of 20 for $24 with each new build. Also, you may want to get a bag of 2 x 6" nozzles, they come in handy for the rear former. One tip, if you buy vPoxy (most folks like aeropoxy for formers and vPoxy for horns, pushrox exits or any place you will see the glue on the exterior (like when you glue the vertical fin, you can wipe off the excess and the little bit of clear you see in the seam won't be visible unless 6" away), be aware that it uses a different gun! It's not a rip off, they just have different mix ratios and one uses half the hardener (smaller tube) than the other, all share the same tips though.

Take your time, be extra careful and pay attention when gluing in the wing mounting formers, there are a few ways to do it but I've found trying to tack them with CA can get the CA in some bad places, like wicked into the brackets in effect gluing the carbon spars in-place! My preferred method is to insert the wings before doing anything to them (lighter) and turn the entire thing upside down (bottom up) and use a fair amount of blue painters tape to align and tape the wings flush with the bottom, then turn the entire thing over and Aeropoxy the ends of the formers only. Then turn it back over, align the seams again and let dry overnight. Once dry, remove the wings and glue the fomers completely with Aeropoxy. Lots of other things you'll encounter, for me wing mounting is a biggie, stab gluing to the carbon spars perhaps the other "take it slow" item, the rest is really a pleasure to build...

Well, different plunger. You can use the same gun and just swap out the plunger piece.

Thanks Ron...just trying to keep up with you!

This has been a hard summer to get into the flying mode, too many other things going on with the kids. But the maiden for sure is going to be at Oakdale.

We have a war bird fun fly at our field this weekend...but maybe July 9th I can get a pass from the wife and get the Sparks up again.

How's the F-18 coming along?
