UPS won't even run on Saturday here. Mine is scheduled for Tuesday and is currently located 3 hours from me. Oh well. Grats that you got yours early. That's really cool.

Get off your simulator and fly in the real world :Ligthbulb:
It would just be a matter of looking at the area well and deciding the optimal placement of it. Anything can be accomplished with good planing and determination. That's how things get done in the real world. ;)
At the very least you could suggest the idea to other club members with the hope of catching the attention of just the right person with the insight and know how to get it done.

what is the minimum C rating lipo that could be used? i know that a 20c 5000mah would provide 100A, the same that the esc is rated for, but would this give too much voltage sag?Currently Fly: Durafly Spitfire MkVb, Eflite P47 1100mm, Parkzone FW190A-8, Parkzone SE5a, Dynam Tiger Moth, Eleven Hobby Bearcat, Parkzone Mosquito MKVI, Durafly Tundra
Unflyable: Durafly Sea Vixen, Parkzone T28 (In temporary storage in tree)

The A4 is ready to fly. Now just 4 or 5 days of decals- LOL Got started using the supplied waterslides. Must have not been on my game as I goobered-up a couple. Sigh. So, it's Callie time
She goes together very easy. No challenges. The fit and finish is outstanding. Gorgeous foam.

Too windy today to Maiden but I took the opportunity to Test for Grass ops.. Uploading vid at the moment & will post later..
Upside... I can reassure Grass flyers that the landing gear is more than up to the task .. My vid will hopefully show that ..
Downside ... Because of the very narrow stance of the mains the A4 is very prone to tipping over & even right on to its Tail causing as per pic.. Doesn't take much at all to tip it over.. I would advise guys who are putting theirs together install c/f rods to reinforce the Tail because it comes off very easily if rolled over on it's Tail.. I'm certainly going to install the c/f rods because it's a total pain if the A4 tips over & the Tail comes off resulting in no flying..
In summary I highly recommend guys spending some time practicing taxiing & runups ... You will Thank me for that ..Be very gentle on the Throttle especially when turning ...Wing skids would be a appropriate mod..I'm sure some of you guys already have something in mind.. Please share if installing some.. Also guys who are thinking of 8s .. CG would be an interesting phenomenon ..3 Photos

I only use the included foam glue or Foam Tac to attach small parts.
For large parts, here's a recommendation: Take a small Philips screw driver (usually the one that comes with some of these foamies) and poke holes on both parts to be joined/glued. Spread a layer of epoxy on both parts, making sure to get epoxy into those small holes which act like fingers. Skim off the excess epoxy, join parts, wipe off any epoxy oozing at seam.... then wipe outside of parts with rubbing alcohol to clean off epoxy residue.
I've been using this method on foamies for 8 years. Very strong!

I'm definitely with xplaneguy on when to use foam glues versus epoxy.
Just about any epoxy will do. Any of the usual hobby epoxies are good for foam. This isn't fiberglass/bulkhead structural bonding so you don't need any of the super epoxies.
I usually date my epoxy and throw out anything that's more than a year old. Also, for foam I usually use either 15, 30 minute or 1 hour to minimize heat from the chemical reaction causing degradation of the surrounding foam and to provide plenty of time for positioning and clean up before it sets.
Epoxy is easily thinned or cleaned up with denatured or isopropyl alcohol.
