Thanks for keeping interest in the Hanger Rat alive and introducing it to a new audience. It's a classic. You did a great job explaining how to trim it. I scaled one up 135%, and added an electric motor with 3 channel RC. I re-christened it the Arena Rat.

[@biko9824]

Did you use UMX electronics? I feel like that would be perfect for that.

[@Jon.Carlsen]

No, the build video is on my channel.

[@kramerdc9]

Thanks for your time and generosity Josh! Much appreciated.

[@kittyhawk9886]

Appreciate you sharing your time with this build. Thank you.

[@joshuawfinn]

Glad you enjoyed it!

I built the plane from scratch following this guide. Great details on CG position and trim.

Thanks!

Hi Josua, I have used all of my OS film so I ended up using gladrap and it kame out quit good. Keep it up with the amazing videos!

I love those things. I have lost three of them to thermals.

Good job

[@Dracsbest]

Hi there Josh, I have been wanting to get into this hobby and have been making a lot of amateur planes out of stuff like foam plates and what not and have been wondering what is a good beginner kit for indoor free flight? Almost every plane I have made does not end well. They keep spinning and I believe it is because of the prop. Could you give me some advice because I have some knowledge on gliders but not rubber powered aircraft thank you and have a good day!

[@samkaplitz9036]

You sure make it look easy! Im interested in the prop bearing & mounting.

[@joshuawfinn]

Check the written manuals on my website for the Easy A-6 and the Parlor Mouse. They show the bearing usage and installation.

[@pea2911]

very helpful video, thanks again I found the trimming tips at the end especially helpful :)

[@user-qq9qb4lb4e]

Thank you so much very much thanks 😊😊🎉

[@A.Netizen.Since.2010]

..Hyper Excellent!! 👍🏻👍🏻👌🏼👌🏼👌🏼 ..What could be a best substitute for balsa?....'Cause I don't have access to balsa wood...! 🤔

[@joshuawfinn]

That's a tough one. There are some old designs based on pine and spruce with thinly stripped bamboo for outlines. Foam for the flying surfaces can be made to work well of course.

[@johnsamuel10]

I always love to see takeoffs from ground. How about a tricycle landing gear? What design changes need to be made to make it happen? Any suggestions?

[@joshuawfinn]

I've built a couple trikes. The biggest thing is to make sure the mains aren't too far behind the CG to get a good rotation and make the nose gear long enough to keep the plane slightly nose high as it accelerates.

[@johnsamuel10]

@@joshuawfinn Thanks. I will try and let you know how it goes.

[@Kanekighoull]

Very nice video but can we use any other method to provide dihedral to the wings?

[@joshuawfinn]

You can use whatever method you want, just so long as you have at least as much as what's shown in the video. It's a forgiving design, but it does need dihedral to fly well.

[@danielzarwell9318]

You are an amazing craftsman. Love you. Do you spray the tissue with water?

[@joshuawfinn]

On light stuff, you don't want to shrink the tissue or it will break the structure, or at least warp it so badly it won't fly. You can, however, steam the tissue to preshrink it and then iron it flat with a clothes iron so that it won't shrink once on the plane.

[@valveman12]

I watched some of your other videos. Amazing how long some of your planes stay up.

[@fennyofficial3621]

Thank you for this. One question. Can I use a ply wood or any wood instead of balsa wood? I’ve been finding one and every hardware doesn’t have it

[@joshuawfinn]

Bamboo maybe. Ply not so much.

[@CliffHarveyRCPlanes]

Hi Josh, what's the function of the two O rings on the rubber motor please?

[@joshuawfinn]

The o rings allow you to load or even unload the wound motor without losing any winds.

[@raulabuyahya4032]

Hi friend,How I can buy it?Thanks in advance

[@ytehrani3885]

I want it to go in right hand circles. I was confused about wing twist. Am I correct in doing the following: Standing behind the plane ( holding it as if ready to were about to be launched): twist the RIGHT wing so the LE tip twists UP & TE tip twists Down (& the opposite for left wing). Thanks

[@joshuawfinn]

That's correct. Then use right rudder and right thrust to make it turn right at the desired rate. Also remember that wing twist is very small, only 1/16" or so at the tips.

Thanks for you Im in Indonesia

[@kolai1317]

Do you use veneer or what type of wood to built one of those?

[@joshuawfinn]

All balsa. Occasionally I use bamboo and basswood for hardpoints.

[@AungAung-ow5sx]

Can I know total weight without the rubber? Nice work.

[@joshuawfinn]

Mine was 6g as I recollect. Hope's was lighter, around 5.5g. I've built them as low as 3.5g by using very thin wire and extremely light wood.

[@AungAung-ow5sx]

Thank you Joshua.

[@LeeRaven-rb4dp]

Hi sir, I am an absolute noob in this field but I just wanted to know that are there any alternatives on rubber bands if I could not get hold of the FaiTan rubber band.I know I this greatly affects flight time but I have to make do with what I have.Thank you!

[@joshuawfinn]

You can use whatever you can find if your goal is just to get something in the air...Banggood and Aliexpress probably have stuff in their online stores that could be made to work. That said, shoot me a message through our website at jhaerospace.com and include some details of what's causing problems with obtaining FAI rubber and I'll see if I can get a solution for you.

[@LeeRaven-rb4dp]

joshuawfinn I will think about it,but thank you for wanting be of help.Will contact if i don't find a solution.Thanks!

I used regular tissue paper. Esaki would be better but it's much harder to find.

OK thanks

[@davidduganne5939]

what's the diameter of the built up prop in your kit?

It's whatever the published size is...7" as I recollect.

what template paper size

[@markojime7964]

Can I glue the parts with super glue?

[@joshuawfinn]

That's what I usually do. Just use only as much as is absolutely needed to bond things (less than you'd think). I recommend Gorilla super glue in the blue cap or Bob Smith Medium CA. Don't use thin CA.

Sir to sell this model do you have to make yourself legalise to sell this model or it’s universal like anybody and sell it ??? Plz sir help me replying answer Have a good day 😁🔥

[@joshuawfinn]

I only produce kits of designs that I either have permission from the designer to produce or that the designer is no longer living. Copyright enforcement really isn't a thing since most designs are never legally copyrighted in the first place.

Go on the USPS website and input the shipping for a 4x4x18" box from anywhere in the US to anywhere in Canada. In short, the postal system hates us. I've tried everything to find a cheaper route.

[@fennyofficial3621]

Thank you for this. One question. Can I use a ply wood or any wood instead of balsa wood? I’ve been finding one and every hardware doesn’t have it

[@joshuawfinn]

Plywood is too heavy and lacks the strength to weight ratio. Go online, find a balsa supplier, and order the wood you need. Sourcing materials locally is a thing of the past because very few brick and morter stores still stock suitable materials. Good balsa suppliers include Specialized Balsa, National Balsa (Aerolight grade) and Model Aviation Products. Avoid SIG and Midwest like the plague, questionable quality and poor supply chain. Balsa USA isn't great either.

[@fennyofficial3621]

@@joshuawfinn ok! Thank you so much! I’ll be ordering online any suggestion where I can order? Also is bamboo also good for the wings? Or does it really need to be balsa? Thank you!

[@joshuawfinn]

Google the 3 I mentioned as working well and check them out. Bamboo is viable but you have to manually strip it down, which is not easy in comparison to sliding balsa through a stripping tool.
