Official Freewing Twin 80mm/90mm A-10 Thunderbolt II Thread

[OV10]

I like using the Scorpion Backup Guard as my peace of mind for the more expensive birds.

Same here on the backup guard. I can recall using 600-800 ma packs for a receiver battery back in my old nitro days. 500 should be plenty as a backup.

Just ordered one for myself. Thanks for the post WC.

[dahawk]

Ditto for me

Guys, sorry. I said transmitter battery. I added it just for weight because it was my first flight with 4000 packs and it was real windy. Can't lose a bird that's not here yet, right? Just me being a little cautious considering the situation and aiming for nose heavy..It wasn't plugged in. We fly stock.

I thought that you had said "transmitter" battery in the vid Ryan. I was just about to post that when your post popped up. If I'm not mistaken, both ESCs are supplying power to the system in parallel, so if that's the case, you already have a back-up source.

Well, I just ordered the Freewing A 10 80mm . Its really too much for my budget, but hey, you only live once !
Am totally impressed with the service Motionrc provides and have purchased many warbirds and two stinger 90s from you guys - great stuff .
Also have a couple of spare 90s for the upgrade if I choose , but I'm sure those twin 80s are plenty powerful!

Hey Ryan ... I am sorry I missed understood on the video. My bad ..... I have also used the scorpion back up guard and like it.... can we confirm that both speed controller bec's are powering the a-10 ??

Doesn't the red wire from one of them get lifted? It has always been my understanding you weren't supposed to connect the output of two BEC's together.

If I'm not mistaken, I think that rule of thumb refers to if two switching BEC's are used, but two linear BEC may be able to used simultaneously on a twin powered plane. Hopefully someone with extensive electrical knowledge can confirm and to describe in detail as to why that may be.

In this jet, I thought the ESC's may be Opto and therefore not have an internal BEC. Instead it would have one large external BEC, but unsure. With the size of these servos, retracts, lights, etc., I would doubt an internal BEC of the rating the Hobbywing ESC's have could handle all of that safely.

Hi Triplanes, welcome aboard!
I guess I'm the official welcomer for all the BC-ites, having been born and raised in Vancouver/Surrey before heading for God's country, Wyoming. Great to have your aboard.

Hey guys...I have searched the thread and can't find the mention about the width/dimensions of the tail. Someone else was asking how it would fit in their car, and I am having the same concern. Post#????Thanks! Rob

Hey Triplane 62, welcome to the squawk. We are practically neighbors, I live on San Juan Island and we can see Victoria from here.You live in a very cool place,Brad

[Shirty]

Welcome to the squawk triplane and gravity. Grats on getting the a10, should be one awesome bird. :)

[Triplane62]

Thx Shirty, now trick is to find a place to fly it ha !

[gravityworks]

Thanks shirty... just hoping i ordered soon enough to get in on the first batch ! :Cool:

My understanding on the scorpion is that it will simply supply backup power to the rx. Is that correct?

That is correct. You are supposed to turn on main power to the RX before turning on the backup. It kicks in if the voltage drops below the 5 v threshold.

I asked Alpha the same question. I can't seem to find his response, but he said it was around 23"-24" across the rudder span.
