How much to convert

[David W]

I like the idea of this brushless job, sick of my nitro engine!
I was wonderind how much it costs to convert?
I have a nitro hyper 9 at the moment so have servoes and transmitter and the usual stuff for a nitro. Has anyone converted one of these yet?
And has anyone raced against nitro buggies? what do they compare like?
Thanks!

£200 for the esc and motor
£75-100 on the conversion kit
£50-£150 per battery (4s)

quite alot all in all

Hobao are releasing a Hyper 9 conversion kit (as seen on Neo-Buggy) and I have already owned it. It is a nice conversion, though you will have to do your research on the bits to go into it. Try RC-Monster for research.

Depending on how long your local track's finals are, you may need more expensive, and larger capacity batteries than electric mentioned. For example, my first conversion, I got 12 minutes run time at a push on a track, which was with a 14.8V 4350mAh Lipo. That packs potential power is (14.8V * 4.35) 64.38Wh. Now, to get 20 solid minutes (so aiming for 22) I need a larger battery, I tried 2 18.5V 3300mAh packs in parallel (capacity * 2, voltage remains the same), which is 122.1 Wh, but due to the extra weight I can only manage 20.5 minutes, which is cutting it fine.

Now I'm trying a lighter set-up with more potential power, one 22.2V 6100mAh battery for 135.42 Wh, which theoretically, according to my previous set-ups, should be good for about 22.8 minutes.

In short, you do need to experiment, and remember that run time depends (with the same set-up otherwise) on voltage AND capacity.

I have raced against nitro buggies, and you will find that the electric will be quicker out of corners, and provided its balanced, will jump better (shorter run-up needed). They need a smoother driving style, and a lot of throttle control, particularly when it is low grip, as you will end up going in a circle if you are throttle happy.

That's me done...

The new RRCi has a race report from Nene Vally where in the 20 min final electric buggies finished 2nd and 3rd, they were 1-2 but needed to stop at the end for a precautionary battery change apparently. So based on that and results from the neo09 it seems they're pretty competitive when you have the right setup, and once you've bought in, the running costs should be almost zero.

I've run mine twice now (Losi 8E 2.0) having never run 8th previously, and first time out qualified 2nd at a nitrocross round, and second time out TQ'd at a club meet at NNRC.

Given my 10th results I would assume that means the cars are plenty quick!!

I haven't run a full final yet, did 11mins at the nitrocross (only had one battery) without issue and leading throughout, and didn't start the final at NNRC due to wussing out on weather. My only concern is how my temps will hold up over 20+ mins, feels very hot after 7 or 8 but don't have a temp measurer, or any idea how temperature would likely increase beyond 10 mins??

Also, may depend on the conversion but the losi is a very slow battery change!!

what gearing motor e.t.c because i have the 1.0 8ight B converted and temps on the medusa motor seem quite high (170F but i have geared down now because i used to run 16/48). get yourself a cheap 2nd chand temp gun some go for around £10 on here and other forums

I have a Losi 8T Tekno conversion with the Tekin RX8 and T8 2250kv Truggy motor and it was very quick on 13/48 but I could only do 14mins on a MaxAmps 4s 8000mah so went to 13/50 and still had plenty of top end and can do just under 20mins with the same pack. Am going to go with a T8 1550kv and go up to 6s 5000mah to get efficency with even more speed so hopefully will last longer.

I run the losi 2100 motor on 4s 5000 cells. Gearing 15/45 (don't know about final drive ratio?).

I'd get a temp gun but how do temps extrapolate. Eg if it 120 after say 7 mins what does this suggest it will be at 10 mins, do temps level out?
