How heavy was your SU34V4 builds
Need this as a comparison for my hobbyking foam build
2200Mah batt A2212 2200kv ESC etc power pack is 270grams
Bringing my build unpainted to 660grams

Think mine was very similar in 6mm Depron. After paint and mods it was about 700g I think but it's been a long time since I checked...
Whoever said nothing is impossible had obviously never tried slamming a revolving door...

Depron hard and expensive to get here in NZ
Using hobbyking model foam that requires quite a bit of reinforcements

Hey DM, I heard rumours you crash better than Mel Gibson and Robert Downey Jr😃

If you build a SU-34 parkjet with a 32 inch or larger wingspan weight is not a issue. I modify my parkjets a lot and build heavy (using a lot of hot glue) and an SU-34 at this size can use an 8X4 prop.

Here is the specs of my last build and it flew great:
Motor: FliPower 2814-1450KV
ESC: 60 amp
Prop: 8X4X3
Battery: 4S 2600-3300 (40C)
Flying Weight 35 ounces (991 grams)
Thrust: 71 ounces (2010 grams)

The SU-43 V4, 32" WS can handle it. The key is trust to weight ratio.

On this particular plane I use model plane foam and dollar tree. As of now I use a mixture of 6mm depron and dollar tree foam which flies a lot better. I also use 4mm carbon fiber tube for the wing area.

What foam did you use to get it so light?
Batt/ESC/motor is @ half of that
Did you KF it?

I build my fuselage assembly with dollar tree foam. My fuselage is built separate and removal from the air frame. See my example pictures.

This maybe the way forward with hobbyking foam
Brown masking paper and watered down PVA glue (Elmer's glue to you guys)
Absolutely no reinforcements
8 grams bare
13 grams finished
Tripled the strength and once cured can be pressed flat between flat surfaces and stays flat

All painted reinforced and battery 820grams so the A2212 2200kv no good got a BR2218 1400kv and an 8x4 WSF should be good for 12-1400 grams on 3s @ 28amps or 15-1800 grams thrust @ 36 amps on 4s
Think keep the little A2212,s for 28 in WS planes
