Hello everyone,
I recently purchased a second hand fpv drone along with some spares.
I am currently practising how to fly the drone on a simulator but in the meantime I thought I could take up a small side project of building a tiny slow flying rc plane with the spare motors, batteries, and props.
I currently have a few GEPRC 1103 8000KV motors as spares along with a few 2s 450mah batteries and 3" props.
I am planning on purchasing a Radiomaster ER4 PWM receiver and a few 2.5g servos to complete the kit.
I am however unable to decide on what ESC should I get from the local market and mainly on what aircraft I should build, I don't have any experience flying, I've built models in the past but have crashed all of them :p.
I would request your help in suggesting some simple small and light weight models that I can fly around my house and neighbourhood.
The weight of all the components so far is:
1x motor = 3.5g
2x servos = 5g
1x rx = 3g
1x batt = 30g
Thrust produced by the motor seems to be about 60-70g.
This leaves me with quite a bit of margin for the ESC and the aircraft, typical 10A escs that I've seen are around 6-10g.
The wing loading of the aircraft has to be very low for it to be a slow flyer as I understand correctly, having a 2s battery already puts me in a disadvantage for this as I can't make the aircraft very small.
Thanks,
Nitesh
Hi Nitesh,
'Indoor' and 'neighbourhood' ( ie, Parkflyer) are entirely different.
Here's a video of 'indoor'.
When he posted this video in this forum 9 years ago, Kiran rc was a young schoolboy.
Later he went off to college and has not been active on the forum in the last 5 years.

And here's one from Glidiator, the 'indoor' expert in this forum:

Thanks Iyer sir,
I was clearly mistaken in my assumption, those builds are on an entirely different level and not something I am looking to get into right now. Kudos to both Kiran RC and gladiator for building those amazing aircrafts.
I am however looking to identify what kind of rc aircraft I can build with the power train I have available. It is definitely not going to be a sub 10g aircraft.
Primary requirements for the aircraft are:
1. Should use the power train defined in the first post.
2. Should be flyable in a large badminton court/small park by a beginner as those are the areas available to me at the moment.
I was looking at the Indore Bipe that you have designed and it seems like a beautiful aircraft, it however seems to be a bit large for the power train that I have, would the Indore Bipe work if it was scaled down to a smaller size?
I was also looking at RCGroups Scratchbuilt foamies and Indoor, Microlight sections and couldn't really identify something that I could use.
PS: You might remember me as rcrcnitesh
@asperised,
I remember you as asperised, who registered for the Lunchbox contest, but didn't post an entry/video!
Perhaps the kit I sent was damaged in transit? Don't remember what happened thereafter.
Here's the Indore Bipe flown by SI174 in a backyard:

I did register for the contest and I did receive the kit, fortunately it wasn't damaged during transit. I had a good amount of fun with it and later passed it on to my younger cousins, let me check they might still have it. Unfortunately, I don't have a video of it from that time. I think by the time I got around to building it the contest got over. Thanks a lot for sending the kit sir, it was a lot of fun using it.
Do you think the Indore Bipe will fly well with a 3" prop? The motor that I have can't take a bigger prop than that.
@Asperised
I have sketched out a Mini Bipe for you.
It's on two A4 size sheets.
All flying surfaces are of 3mm depron.
Fuselage of 3 layers of 5mm depron.
Dihedral 2cm each side on top wing, 1.5cm each side on bottom wing.
Hope this helps.
Regards
Iyer
