Default Slotos 700. Protos 700x made for low head speed.

Decided to make a 12s low head speed Protos 700x. Needed to drop some weight. It has become an addiction to see how many parts I can remove and still have it fly.

That's very interesting! So what does it weigh now? (with a canopy)

4291g right now as you se it with an R2 prototyping cap pack on it. I added that after.

No canopy yet. Doesnít fit. Thinking to cut up a couple old canopies and make something similar to the Raw canopy.

Just realized I weighed the Heli with the blade holder. Which surprisingly weighs 41g.

So 4250g is the current AUW.

That must have been a heavy helicopter before the diet. Although not for really slow speed, I rebuilt a Logo 500 into a 6s flybar 690SX. It weighs in a 3.54kg. If I went with a 12s battery system in it, I would use 3300 packs and that would come in around 4 complete with canopy. I'll be watching this to see how you end up when it is completed. It really looks like a race machine set for the Bonneville Salt Flats. Take care.

The Protos 700X or 700 Legerro are not the heaviest but not the lightest either.

I know a Logo would be really light with the set up I have. I just donít like them. Never have been a fan. Then recently worked on a build for a friend. Got to know the ins and outs. Really not for me.

The Protos 700/800 is my favorite Heli of all time. I have 2 flying and 2 extra airframes plus a hobby shop of spares.

I am looking at an XL Power 700. To do something similar. But it wonít be as cool to me as this Protos.

Also, this Protos platform was originally designed as an 800 in the V1. Every version after is still over built and designed to run it as a beyond over powered 800. So really every 700 version is a cut down 800 with a head, power train and frame to accommodate all the 800 stuff.

So it is what it is. But I just love them. So versatile and the sound is like no other.

If you do it as an 800, you gain a lot of disc area for a relatively small weight addition.

I have thought about that. Most of my extra tail parts are 800 size. And I have some Switch 753ís and Rail 806ís I am not using.

Could be a 10 lb. 800. That should fun. Would sound amazing

Very nice! but appears it may only be 6S. Is it 6 or 12 cells?

My 700 for LHS is 4414 including canopy and 12s (9 and 3/4 lbs), 3055g without batteries. Not sure what canopy weighs but obviously under 3kg without batteries or canopy. It's a "super stretched" E5 though. I find stretching the smaller mechanics helps more than just eliminating un-needed bits,.. but of course you'll have a much more robust machine with the larger/heavier mechanics.

You;ll certainly enjoy this machine,.. weight makes all the difference in the world when spinning them slow.

12s. 2x 6s 2450 mah.

I know stretching is the way to go. This is just for a fun different project plus I have so many Protos parts and airframes. It is my all time favorite helicopter so I figured why not. It will never be the lightest Heli. I am ok with that.

Looks like you are trying to create something along the lines of the Henseleit TDSF? Might be worth asking Henseleit if you can get your name on one for a possible next batch. They have indicated that if enough interest they could do one final batch. That's a 2.4Kg (ready to fly) 700 and it's awesome.

This has been mentioned before. In no way am I trying to create a TDSF. When removing parts from basically any pod and boom 700, you are going to end up with something that looks like this. It is basically unavoidable.

I am doing this project because I enjoy the challenge but also I love all my Protos Helis. I have many 700/800 airframes and parts. No need to get into another brand/design.

What headspeed are you running, and what flight time do you get with those batts?

Currently running around 1200-1400rpm. Having some vibration issues and can’t seem to get lower. I get about 6-7 minutes on 1300-1400rpm.

I didn't mean to imply that you were in any way copying the TDSF. What I meant was the concept you came up with in seeing how much weight and unnecessary 'stuff' could be removed from a 700 and still have a 3D capable heli, was the exact same concept that Jan Henseleit had when he designed the TDSF.
So I thought you might be interested in one...

No worries mate. I get your point.

I just donít think that the TDSF is really a ďconceptĒ. It is just physically what is left that is the minimum to fly. Hence why the Slotos ended up very similar.

I have worked on a TDR MKII a few times. Really not a fan. I applaud the idea but they are not for me.
