I was wondering if the micro jet v3 would work on the F-22v2 with Dollar Tree Foam Board with the paper on?

Good question I like building with Foam Board.
Have you or anyone built any RCP planes with foam board?

I shrunk the plans for the RCP.ezf-35 (when printing) to fit on 20x30 foram board. Looks amazing, feels super stiff and light (with no bracing). But then you have to make the prop hole bigger and prop down from 6x4 to 5x5, or cut threw the frame. Waiting for the rain to stop to test a new 5x5 prop.
I've built the FliteTest nutball, delta and funbat but no luck keeping them in the air so I decided to go full RCP "The New Course". Fingers Crossed (started rc aug2012) Finally success, FT F22, RPC F35 & now funbat. -Thanks RCP!

I would say don't bother. The mjv3 is marginal on a depron f22 v2 and the dollar tree foam board with paper will weigh at least 20 % more. I know elmers board weighs 40% more than depron and us unusable with the mjv3. Rather than being very disappointed, I would bump up the motor since even with depron it can use more. There is a great motor from heads up RC - power up 450 zoom that costs $17.95. They have excellent shipping and customer service. I think they are a family run business which I like.

Or, if you can wait, then the ntm prop drive 2200 from hobby king is the same price.

I just built my F-22v2 at full scale but I took off the paper on everything except for the wings and the elevons. It weighed in at 19oz and I check the mjv3 specs and it says it has a 24oz of thrust hopefully this will work.

Without paper it's lighter than depron so that will work fine as long as you can keep it stiff enough not to flex and flutter. The same plane with paper on would be 26/27 oz.

DTF w/ paper is EXTREMELY flexible. Without paper it snaps like a tooth pick, but is much lighter. So I would recommend making the nose with the paper and the rest without.

I have built all my RCP airplanes out of foamboard with the paper on. Search the forums or check the resources thread, there's tons of info posted already.

A glue coating makes poster board indestructible. Yes the heavy hot glue. Oh No .

Ok I just got back from working abroad for a few months...
Back in april/may I went out on a one of the only days with no rain (seattle area). It was very apparent that my F35v2eb DTF build was too heavy for the motor (Turnigy D2826-6 2200kv w/3cell) and 5x5 prop. (probably for the wing area as well). DTF w/ paper and very heavy handed hot glue. It wing rocked and face planted in a puddle, paper all over the plane was peeling off immediately! Same thing kept happening every attempt.

After getting settled back in I pulled it out and cut out room for a 6x5 prop and took it out. Wow it was heavier than I remembered. I put it up it went around, flipped, wing rocked and belly landed hard. The frame snapped in four different places (cut too much out and the paper was no longer attached so no strength). Shelved it and started a new build.

This new build I am trying paper off internal parts, light hot glue, minwax coating, bamboo support, and a little bigger (so the frame just fits DTF). I may try like bharding62 says only wings and the elevons.

note: I built with depron while in Australia and DTF is not very good in comparison. imho (out side of price and availability any how) The only reason I'm still using it is 1. I love the price and availability, 2. I love the price and availability!!! (I hate waiting on shipping!) and 3. I bought about $15 worth before I left.

P.S.
Squishy you are one of my RC heros! U ROCK.
Lie "I have built all my RCP airplanes out of foamboard with the paper on" I know cuz ur F35v2 build vid
. j/k just an easy plug for your awesome vid. Dam free F35v2eb made me pull the trigger and buy the RCP course. Now I just need some good weather and some time off 2 build/fly one! (check and check :cool

I still have two sheets of that stuff, haven't used it yet (I am thinking it might make a good laminated wing), it's really hard to get here in my area because of the warm climate in California, the hardware stores just don't stock it. I had a friend who ordered a big stack of fan fold blue core and he gave me a few sheets. I think it's great for prototyping designs or for 1st drafts but I would still make build my finished product out of DT foam it's thicker and stronger, and heavier...I think that's the only complete airframe I used anything other than DT or EPP...I have never purchased depron, too rich for my blood and reckless ways......I was wondering if anyone was going to catch that...you pay attention dude...nice catch...notice the vertical stabs at DT foam, , so I did use some...

That video is a good display of how slow that frame is, that's a monster jet on there, with a 7x6 prop! Listen to the sound and lack of speed, it's very inefficient...

I have only used $tree foamboard and always leave the paper on. The only plane that I had power to weight issues is the RCP F-18 V2. I only have used the 2826-2200kv from HobbyKing. Had enough to fly, but that was it. I also only use hot glue, and I'm not very conservative with it.

I got to say THANK YOU DAVE POWERS,
for the award and yes I really like this stuff..
Know Keith here is a easy way to work with dollar store foam..
and some of it's drawbacks..




I still paint mine planes but keep most of them on dry land..
This is proof it is paper??

I use dollar tree foam boards all the time and I think that they are good especially for bevels, score cuts (since you always have that last layer of paper holding it together), and peeling off one layer of paper gives the board a lot of bend flexibility to the peeled side. The bad thing is they are easy to be screwed up, and they are hard to be refined at the cuts--you know, need to score and peel part of the paper off before sanding.
