Thread: Motor mods to old Ripmax P-51 mustang ARF
19/10/2018 14:58:56

Tim, for what it is worth, I have two 36mm diameter Mega 22/30 motors, one 910kv and one 1250kv.

Both used on 4S.

The 910kv has an apc 10x5 fitted and shows about 450W on fresh charge.

The 1250kv has a 6x6 (cut down MA 8x6!) and shows 550W on fresh charge.

Somewhere about in the middle - 8x6? - might be about right for you?

I would have thought the 4max inrunner would be find. As for the different kv, just a case of choosing a different prop to suit it.

Actually come to think of it, the 1100kv would be about right for a 4S setup.

The Mega inrunners are really nice bits of kit. Is anyone distributing them in the UK now Puffin changed hands?

Absolutely disconnect the red wire at each ESC, if using a separate UBEC (or battery).

"I do need two batteries because it will draw too much current with only one."

Say what? You could fit one single larger battery. Of around double the capacity of the individual pack size. 4S 8000mAh. Here's one for £56. With max rated discharge of 240A. I'd de-rate that to about half - being a hobbyking effort - but I would think 120A would more than cover your needs.

On the other hand, 4S4000 is quite a useful size pack and you might want to use a single one in another project. Your call of course.


"I shouldn't connect them in parallel because if there's a miss-match it could result in a high current condition"

I would personally absolutely connect them in parallel.

Seems the nose is somewhat fixed to that beam mount setup.

Maybe one of these being sold on Ebay would work?

That's brilliant Dave!

32 sq ft of wing area is very nearly as much as the Cri-Cri. A little lower loading though.

Clearly, the next move would be to use 4 sheets of 8' x 4'... although at 128 sq ft of wing, that would make a passable ultralight.

Nice one Dave. What does the motor setup draw, I guess about 100W?

You can get foamboard from HobbyCraft

https://www.hobbycraft.co.uk/white-foam-board-a1/539724-1000

4 big A1 sheets for £10. They also sell cheap hot melt glue guns.

I'm using the same stuff to make a Flying Carpet at the moment.

Nice one david many thanks. I do have a couple of old cards I could use.

Made a motor mount tonight.

Not very complex. Several horizontal bits are hot glued to the carpet. Then the firewall goes on the front of them. I Used up a bit of scrap 5mm ply.

I worked out I will need about 9oz at the front of the carpet to get the balance right. lipo willbe 4oz. Motor is 3oz i think. This means I may have to move the servos to the front and use some thin pushrods. Or the pilot will have to go on a diet. We will see when the bits arrive.

I dug a bit more; https://www.paypal-community.com/t5/Archive/payment-reversal-scam/td-p/307072

If you had posted the clobber, and attached appropriate tracking number, after delivery was confirmed you would have received the funds 3 days later (assuming everything was above board at both ends).

If you are not a regular paypal user and/or seller, then funds are not automatically 'released' straight away into your account.

Thread: Evolution EVOe999 Radial engine

"if you know the power and rpm of the engine you can calculate torque. "

You can calculate average torque. Peak impulse might be rather higher.

I imagine you would need to cater for the peak, plus tolerance.

The LMA might be a useful port of call if you haven't already?

The EVO manual shows a radial mount already attached to the backplate. Can you not ensure the firewall ends up in the right place to bolt that directly on?

EVO manual here.

The RC world can't even standardise the plug on the end of the flying leads! devil

Consumer type lithium cells - like 18650 - are in a standard hard case.

A buyer can trigger this by making a paypal payment using a credit card, and then calling the card company and claiming the payment was not authorised by them. I'm sure there are other ways, too.

As a seller, if you accept the payment and meet the usual sellers requirements (tracked/signed postage, attach reference to the payment exchange) then you are generally ok to keep the payment.

or google for 'paypal unauthorised payment'

If you sell via Ebay there is another layer of seller protection made by Ebay. The fees are a few % higher, so you would want to set your price accordingly, or go with an auction. Generally I've found the best sale prices come from auctions, even accounting for the fees, the exposure to potential buyers on Ebay is so wide. I've sold a lot of IC motors via Ebay in the past and never had any trouble.

"I have used in the past making up a jumper lead which I plug in for each flight for power (3-4mm gold connectors)"

Just thought this was worth highlighting.

No reason the jumper cable must be restricted to arming our electric motors.

Equally valid for RX power in bigger models!

Very low cost and easily doubled up if you want redundancy.

12x8 sounds quite large! What does the wattmeter say you're getting on full power?

Mine shows over 800W fully charged. It comes down warm but not hot.

Thread: LiPo dimensions

That is a good £40. Mine is on nearly 150 flights now and a bit the worse for wear. For what it is worth, my pile of 3S 1000mAh lipos varies in size and weight, too, the lightest is 80g and heaviest nearly 100g.

16/10/2018 15:21:36

I think the packing thing was more devious than that - they could pass them off as bigger capacity if they looked bigger. I saw a few threads on RCG where people had opened their 'bargain' lipos and were a little upset.

"Yes, now Geoff knows why the thing won't go in his box."

Coffee in keyboard!

On reflection, none of this helps at all, does it?
