Greetings
Guy RuslanG is engaged in the basic working out and frame manufacturing. At present In photos last version under drawings and the first in metal. ESC MMMv5 The regulator altered on this method http://photofile.ru/users/berserk80/96565786/ Such variant is named "inverted" The development beginning in this direction so-called Karabelnikov ed esc http://forum.rcdesign.ru/f27/thread1...ml#post1404006 http://forum.rcdesign.ru/f27/thread1...ml#post1411973 Basically it is made for Truggy Buggy with a horizontal plate. RuslanG with completions has applied this variant of alteration esc + has added the radiator. |

Motor mount under way... still need some support between the two parts :)
Alza racing delivers: http://www.rc-monster.com/forum/atta...1&d=1300780233 Hmm... with a skid plate and some sort of dogbone protection the batteries could be squeezed in between the TVPs. Motor mount was made with a centered 1717 since this allow me to push it further back. http://www.rc-monster.com/forum/atta...1&d=1300780233 On the other hand... a wide skidplate and a cut out in the bottom of the TVPs = batteries mounted low and horizontal: http://www.rc-monster.com/forum/atta...1&d=1300780233 |
Where will the steering servo go with the batteries up front?
Interesting idea about the cutout in the bottom of the TVPs. If the batteries were up front they shouldn't cop much abuse there. I've been toying with the idea of mounting a battery sideways above the center driveshaft. Could move it back and forth to tune the balance as there would be plenty of space. |
With the batteries "inside" I'd have to make a cut out in one of the TVPs, flip the steering arm 180° and mount the servo on the outside.
Its safe to say im leaning more towards the cut out approach... especially after I got the solid TVPs from Alza :) |

very nice!!! im happy to see that dejan at alza is getting more custom now!
Interested to see how this turns out... IMO i would like to see you widen the internals of the chassis, and fit the lipos either side of the rear shaft. I like the idea of moving the steering to the outside too! Are you going to make the necessary cut outs yourself? |
Im not really sure how much details regarding other rc sites we are allowed to post here before the board police pulls us over?
Heres the quote I got from Dejan: plain plates without cutouts and holes (besides bulkhead mounting holes). The weight is for 2 TVP's: Carbon 3,2mm 280g XL TVP's 60€ ALU 3mm 480g XL TVP's 25€ ALU 5mm 760g XL TVP's 30€, Hope I didn't step on too many toes there? Anyway, if you have questions regarding Alza racing I suggest you shoot dejan a mail. He seems like a nice guy and is really fast at communicating as well as producing the parts. The rest of the custom work I'll do myself. Straight cuts and hole drilling should be manageable :) |

A little prototyping progress...
Cardboard TVPs with cut outs and batteries: http://www.rc-monster.com/forum/atta...1&d=1300894939 I need some sort of end stop on both sides of the dogbone. There must be a U profile with the right dimensions somewhere! http://www.rc-monster.com/forum/atta...1&d=1300895094 Servo can sit in its normal spot (more or less): http://www.rc-monster.com/forum/atta...1&d=1300894939 Battery placement in relation to the dogbone (vertically): http://www.rc-monster.com/forum/atta...1&d=1300894956 Ive got 1cm of 3mm thick alu on the bottom side of the TVP cut out at each end of the battery as it is. I wonder if its safe to go even lower? Damn I should have taken the 5mm TVPs! :whip: If I could go lower it would help servo mounting... still for my friends inrunner project we need a different servo placement anyway. Bright ideas are welcome :) |

Because this is the stuff we need to fit into the construction:
The fat outrunner: http://www.rc-monster.com/forum/atta...1&d=1300895785 9 LiPo cells (its not the packs we'll use but you get the idea): http://www.rc-monster.com/forum/atta...1&d=1300895785 Its slightly crowded at the backend where I have CD and 1717: http://www.rc-monster.com/forum/atta...1&d=1300895785 We'll most likely have to do a cut out in the "bulkhead plate" otherwise the angle between the drive cups will be extreme... more fun challenges :) |
I was planning on doing my 5T plates with the batteries cut out in a similiar fashion. My biggest concern was protecting the batteries from damage on the sides.
As for the 1cm... if you have a bottom plate that ties together the sides underneath the batteries, that should make up for any weakness in the TVP itself. |
I guess :)
And I also wonder if it matters a whole lot if the 1 cm of material is moved up above the batteries and then the battery bay is inserted as a skidplate? To be continued tomorrow :) |
Probably not. If you look at my thread thats exactly what I had arrived at as a plan of action.. at least until I decided to switch gears and just use a truggy as the base platform (trying to turn a savage into a truggy and then into a 5th scale buggy seemed to be a lot of unnecessary work).
|
That's a darn big motor.
|
Hehe just skimmed your thread... its more or less the same plan... except for the 5th scale bugy part :)
|
firstly i love the lipo placement... im sure you can come up with a way to protect them!!!
You are going from an already overkill 1717 to an out runner? what sort of specs is it? kv? max rpm or lipo cells? It is HUGE! will you need a new centre diff setup? |
