I have more or less finished converting a Robbie high wing trainer into a twin 70mm 4s (2842-3400kv), powered model.
EDF's under the wing fairly close to the fus. same ESC'S and all settings etc. equal.
During the balance process, I found that a 40-80c CNHL 2700 MAH 4s lipo balanced the model ok.
However, when running up the motors, they sagged considerably after about ten seconds at maximum throttle.
Obviously I am trying to take to much from the Lipo!.
I am not an expert on the subject, is it the C rating, capacity? or something else?
The packs are fairly new and charged up ok.
Can anybody help please?.
You need to post a bit more information about the edf units and the speed controllers.
If you are running 2 70mm fans off a single battery you are probably drawing too much current for the battery to maintain voltage. You need to connect a watt meter/ammeter just after the battery and monitor current draw and voltage.

Does that include the ones that don’t understand distribution curves and statistical analysis?
Someone told me that the average person doesn't understand statistics, I think that's mean and that the probability is that he's an out and outlier and prone to making random statements. I have no confidence in him anymore as he's repeated this with some frequency and my hypothesis is that his behaviour isn't normal.

They are a bit heavier than a Wot4 and don't fly particularly slowly, on the other hand they are are quite robust, mine went through 2 trees during its early life with minimal damage.

Yes,it is. Been driving them since Reliants vanished.
My dad had a Reliant Rialto, I took it up to 70 mph once, brown trouser time, nearly rolled it on a corner too. Anyone who's driven one deserves a medal!

I have a 5 year old Riot which flies on a 3S 3000 on the original motor and a 12x6 prop it has perfectly adequate performance for a poor weather hack. I later replaced the motor for a more powerful one and it will climb vertically. The original set up drew 28 Amps at WOT, the uprated setup draws 38 amps.
If you want to run on 4S you may need to drop the prop size a touch. I am not sure what current the original motor is rated for.
You may have trouble fitting a 4S battery into the battery compartment, I've cut the bottom out of the battery compartment in mine to make it fit a wider range of batteries.The suppliers recommend an 11x5.5 or 10x6 prop on 4S batteries.

I now have visions of Airbus engineers buying AS3X receivers......
Surely that should be Boeing?
And each plane would have just one.
And they wouldn't tell the pilots where it is, what it does or how to turn it off.

Pretty sure this is the version to go for? (When I get out flying don't I don't crash everything I own, I'll treat myself to the AG01 Gimbals)
You are putting the cart before the horse.
Join a club.Speak to other members, especially the instructor(s).
Ask for recommendations.
Make a reasoned decision.
Purchase transmitter.
I speak from experience, decided to return my first Tx purchase as I realised that compatibility with instructor's equipment was a big advantage.

Nice.
I just wanted something around the £100 - £200 mark that does everything I need. Not interested in stabilization etc
Jets and such are a long distance off and I just wanted a reliable older but better quality transmitter with quite cheap receivers.
I haven't been to a club yet and I have no worry about going for a model that isn't used by the clubs I do attend as I am fine with menus etc.
I have seen some DX8's that are around £100 - £150. Is there much of a difference between the DX Gen 1 and 2 when it comes to performance?
You may have problems with spares availability or the Gen 1 DX8.

When restarting after a considerable gap I bought the brand that was most popular in the clubs I joined and (possibly more importantly) the brand my instructor used which just happened to be Spektrum.

On a practical note, if you open the throttle slowly (maybe even if you do it quickly), the prop blades may catch the corners of the fuselage...... maybe check now rather than when it's 200 feet up?
My comment was a lighthearted one. But the prop blades will also not fold properly unless the prop is vertical or horizontal. Maybe fit a spinner that's the same dimension as the fuselage diagonal measurement.

Finished all the little tyding up jobs, wing bands arrived so I put it on my Multiplex c of g balancer thingy.
With the lipo pushed forward as far as it can go it balances right on the money, so its good to go, roll on a bit of sunshine......
Total weight 3lbs 10ozs, not sure whether that is good or not, no recommendation in the build article,but it is what it is.
Surely there must be a market for square spinners?😉

I agree, that on pusher models the relationship between the propeller and flying surfaces has a major impact on the noise. I have Four models with pusher props, non are noisy, even my small Dornier 335, in all cases the prop is some distance away from the flying surfaces, makes a big difference.
Yesterday the weather here was horrendous. I needed to go to Manchester, some 60 miles away. I was very, very, surprised that field after field on the journey, were partially flooded, in many cases with quite large lakes. I have never seen anything like it previously. One field my wife commented on, it was completely flooded, with just the rows of ploughed furrows to be seen.
Driving was surprisingly easy, very few cars and trucks on the M6. Not that you could see them, as all was enveloped in spheres of spray. I was doing a steady 50 mph, probably 50% of the vehicles, including trucks were at the same speed. Of the remainder 25% were fractionally faster, whilst the remainder where in the +70-80 miles per hour, leaving a linear wall of spray.
The better halves golf and bowls competitions have been postponed, on after another. Many of the golf courses have been closed here, although those on sand (links), generally remain open. Those open (the one I see from the bedrooms) is not often been played as the members are nesh, so it would seem. Much to my wife's annoyance her first match at this course has been put back.
Enquiries with respect to my club (as a member, not by ownership) is open, although for hand launch models, waders, and being prepared to move the ducks and geese on, the Gulls just laugh at you. Ah, yes, a 4*4 is advised to actually get down to the club, the puddles on the various roads, can be navigated with a little care.
I will have the start of a problem in a few weeks time, road works are scheduled to start at the end of this month, to last a a few months on four of the three roads out of this two horse town. Surprisingly our new link road although still on programme for completion, will now be delayed for 3 months, due to the rain. It was to open at the beginning of April. Only taking 4 years by the County Council, of a two year programme, whilst meeting the all programmed date for completion, costing almost exactly the same as the cost of a Motorway (including all bridge infrastructure etc.)per mile. Much to my surprise it is a standard two lane road. The question of how long will it take to get to the club field, will it be doable.
Need one of these.
